Self-Certification of Origin — EPA/FTA Origin Declarations and Recordkeeping Obligations
Interlink編集部What Is the Self-Declaration System?
The self-declaration system is a framework under which exporters, producers, or importers declare that their cargo qualifies as originating under agreements such as EPAs or FTAs and request the application of preferential tariff rates under those agreements.
Unlike a system where a third-party issuing authority issues a Certificate of Origin, the self-declaration system requires the declarant to verify origin themselves, retain supporting documentation, and be prepared to explain the origin claim if customs authorities conduct a post-clearance review.
The self-declaration system has become an important origin certification method under recent EPAs and FTAs, including CPTPP, the Japan-EU EPA, and RCEP. Because it does not require going through an issuing authority, it can make ongoing or high-volume transactions more efficient. However, if the system is used without documents that support the origin claim, preferential tariff treatment may be denied during customs post-clearance verification.
In practice, it is necessary to confirm not only the wording of the origin declaration or origin declaration statement, but also HS codes, Product-Specific Rules of Origin, CTC, RVC, processing criteria, cumulation rules, de minimis provisions, shipment criteria, supporting documentation, and the scope of responsibility of the declarant.

Purpose and Background of the System
The purpose of the self-declaration system is to simplify proof-of-origin procedures and allow EPA and FTA benefits to be used more quickly. Under the third-party certification system, it is necessary to apply to an issuing authority in the exporting country and obtain a Certificate of Origin. In contrast, the self-declaration system allows exporters, producers, or importers recognized by the agreement to declare that the goods are originating products themselves.
Because the process does not go through an issuing authority, it can reduce procedural burdens in continuous transactions, high-volume trade, or repeated imports and exports of the same product number. However, the simplicity of the system does not mean that responsibility is reduced.
Under the self-declaration system, the declarant must retain documents that explain the basis for the origin determination and must be prepared to respond if customs requests verification. The origin declaration or origin declaration statement is only the starting point for claiming origin. Supporting materials such as HS codes, Product-Specific Rules of Origin, materials, processes, costs, and transportation routes are critical.
Scenarios Where the Self-Declaration System Applies
The self-declaration system is not uniformly applicable across all EPAs and FTAs. Its use depends on the relevant agreement, exporting country, importing country, applicable period, declarant, and required documentation.
| Application Scenario | Common Issues | Documents to Check | Practical Measures |
|---|---|---|---|
| When using CPTPP | Exporters, producers, and importers may each act as declarants, making management of mandatory declaration details and document retention essential. | Origin declaration, commercial documents, HS codes, PSR, origin evidence | Ensure the declarant retains documents that can substantiate origin. |
| When using the Japan-EU EPA | Issues arise around the origin declaration statement, exporter reference numbers, and importer’s knowledge. | Invoice, commercial documents, origin declaration statement, REX number, corporate number | Verify the EU-side exporter number, Japan-side corporate number, and their correspondence to the relevant cargo. |
| When using RCEP | Certification methods differ by country and timing, including third-party certification, declarations by approved exporters, and self-declarations by exporters, producers, or importers. | Documents confirming certification method, Certificate of Origin, origin declaration, agreement operation documents | Confirm available certification methods according to exporting country, importing country, and applicable period. |
| When the exporter makes the declaration | If the exporter is not the manufacturer, they may lack complete manufacturing process or material information. | Supplier declarations, material lists, process charts, manufacturer documents | Confirm that there is a system to obtain necessary documents from the manufacturer. |
| When the producer makes the declaration | The producer can explain origin more readily, but issues arise regarding the extent of disclosure for pricing or manufacturing information. | Process charts, material lists, RVC calculation data, manufacturing records | Confirm what range of documents can be shared with importers and exporters. |
| When the importer uses self-declaration | If the importer does not hold documents explaining origin, post-import verification becomes difficult. | PSR verification documents, material lists, process charts, RVC calculation data, transport documents | Confirm in advance that documents can be obtained from exporters or producers. |
| When importing the same item number repeatedly in ongoing transactions | Previously checked content is easier to reuse, but changes in materials or processes may go unnoticed. | Item number tables, specifications, material change notifications, periodic confirmation documents | Periodically verify updates to origin-related documents. |
| When considering post-import refunds or corrections | Handling varies depending on the import situation, agreement deadlines, and submitted documents. | Import declaration, origin documents, refund-related documents, agreement reference documents | Confirm details before import declaration rather than relying on post-import remedies. |
Common Misunderstandings
With the self-declaration system, misunderstandings such as “It is easy because the declarant can issue it,” “An origin declaration statement alone is sufficient,” or “The exporter can handle everything” often arise. In practice, the declarant, applicable agreement, supporting documentation, record-keeping obligations, and customs post-clearance verification must be managed as an integrated whole.
| Misunderstanding | Actual Consideration | Potential Issues |
|---|---|---|
| The self-declaration system can be used by anyone under any agreement | Whether the self-declaration system can be used and who can act as the declarant varies depending on the agreement. | Declarations prepared using an unsupported method may result in preferential tariff rates being denied. |
| Creating an origin declaration proves origin | The origin declaration or origin declaration statement is only the starting point; supporting documentation such as HS code, PSR, materials, processes, and costs is required. | The declarant may be unable to demonstrate origin during customs post-clearance verification, leading to denial of preferential tariff treatment. |
| The self-declaration system is simpler and safer than the third-party certification system | While issuance procedures are simplified, the declarant’s responsibility for document management increases. | Continued use with insufficient internal controls may lead to cumulative denial later on. |
| The Authorized Exporter System and the self-declaration system are the same | The Authorized Exporter System allows exporters who meet certain requirements and have been authorized to make origin declarations. It may be treated as a type of self-declaration method, but prior authorization is required. | Exporters who are not authorized might mistakenly believe they can declare as if they were authorized exporters. |
| The importer only needs to check the exporter’s origin declaration statement | The importer must verify not only the presence of an origin declaration statement but also the applicable goods, agreement, country of origin, transportation route, and whereabouts of supporting documents. | Failure to obtain documentation from the exporter or producer during post-clearance verification may prevent the importer from explaining origin. |
| Importer self-declaration means no cooperation from the exporter is needed | Although the importer must explain origin under importer self-declaration, documentation from the exporter or producer may still be required. | If the importer does not have material lists, process charts, or RVC calculation documents, they may be unable to respond after import declaration. |
| The self-declaration system is always available under RCEP | Under RCEP, operational differences between countries and phased implementation mean that available certification methods vary by exporting country, importing country, and timing. | Declarations using methods that should not be used may result in preferential tariff rates being denied by the importing country’s customs. |
| Revised declarations after import can be submitted anytime to recover duties | Post-import corrections or refunds are subject to restrictions based on the agreement, deadlines, submitted documents, and import declaration conditions. | Failure to verify the requirements at import may result in an inability to apply preferential tariff rates retrospectively. |
Difference from the Third-Party Certification System
In the third-party certification system, the issuing authority in the exporting country issues the Certificate of Origin. Exporters or producers submit the necessary documents to the issuing authority and use the issued Certificate of Origin during import declaration.
In the self-declaration system, the exporter, producer, or importer declares origin without involving an issuing authority. Therefore, instead of relying on the issuing authority’s examination, the declarant must retain supporting evidence of origin and respond to customs verification as needed.
| Item | Self-Declaration System | Third-Party Certification System | Practical Notes |
|---|---|---|---|
| Certification or declaration entity | Exporter, producer, importer, or another party recognized under the agreement makes the declaration. | Issuing authorities such as Chambers of Commerce issue the Certificate of Origin. | Confirm who bears responsibility for certification or declaration at the outset. |
| Involvement of issuing authority | Generally, no issuing authority is involved. | Issuing authorities review application documents and issue the certificate. | Note that the self-declaration system does not include prior review by an issuing authority. |
| Responsibility for document retention | The declarant retains supporting documents for origin and responds to customs verification. | Applicants must also retain supporting evidence for origin and application details. | Document retention is important in both systems. |
| Suitable situations | Ongoing transactions, high-volume trade, or cases where the declarant can manage documents. | Transactions where the importing country or agreement requires a third-party issued Certificate of Origin. | Check which certification method is accepted under the relevant agreement. |
| Main risks | If the declarant lacks documentation, responding to post-clearance verification becomes difficult. | Delays in issuance, corrections, reissuance, and document inconsistencies can create problems. | Do not select the system based on speed alone; verify the document management system. |
Relationship with the Authorized Exporter System, REX System, and Importer Self-Declaration
Around the self-declaration system, there are similar schemes such as the Authorized Exporter System, the REX System, and importer self-declaration. While all relate to rules of origin certification methods, they differ in applicable agreements, registration or authorization requirements, declarant parties, and declaration contents.
| System / Method | Overview | Relation to the Self-Declaration System | Practical Notes |
|---|---|---|---|
| Authorized Exporter System | A system under which exporters meeting certain criteria are authorized and make origin declarations on commercial documents. | It is related to self-declaration-type certification methods, but prior authorization as an authorized exporter is required. | Confirm the authorization number, scope, applicable products, and relevant agreements. |
| REX System | Short for Registered Exporter System, a mechanism for registered exporters to declare origin information. | It is connected to self-declaration-based origin certification in EU-related transactions. | Verify whether a REX number is required, monetary thresholds, applicable agreements, and the contents of the origin declaration statement. |
| Exporter self-declaration | The exporter declares that the goods are originating products. | It is a type of self-declaration system. | If the exporter is not the manufacturer, confirm whether manufacturing information can be obtained. |
| Producer declaration | The producer declares origin based on manufacturing information. | It is a type of self-declaration system. | The disclosure scope of manufacturing and cost information may become an issue. |
| Importer self-declaration | The importer declares origin themselves. | Among self-declaration types, this imposes a greater record-keeping responsibility on the importer. | Confirm that the importer holds documents capable of explaining origin. |
Differences in Declarants
Under the self-declaration system, the information that can be verified, the documents to be retained, and the response to customs verification vary depending on who acts as the declarant. Exporters, producers, and importers cannot use the system under the same conditions; it is necessary to confirm which declarants are recognized under each applicable agreement.
| Declarant | Who Makes the Declaration | Information Easily Verifiable | Required Documents | Points to Note |
|---|---|---|---|---|
| Exporter declaration | The exporter declares the goods as originating products. | Export cargo, transaction documents, supplier information, documents from the exporting country. | Origin declaration, origin declaration statement, material documents, supplier declarations. | If the exporter is not the manufacturer, they may not have sufficient manufacturing information. |
| Producer declaration | The producer declares based on manufacturing information. | Manufacturing process, raw materials, cost information, processing details. | Process sheets, material lists, RVC calculation documents, manufacturing records. | There can be issues regarding how much information can be disclosed to importers or exporters. |
| Importer self-declaration | The importer declares the origin status themselves. | Import declaration information, import documents, documents obtained from the exporter. | PSR verification documents, material lists, process sheets, RVC calculation documents, transport documents. | This method is difficult to use unless the importer possesses documents that can explain the origin themselves. |
Comparison of Self-Declaration Systems under CPTPP, Japan-EU EPA, and RCEP
The self-declaration system differs by agreement in terms of the declarant, required documents, content to be stated, and points of caution. Although the self-declaration system under CPTPP, the Japan-EU EPA, and RCEP all raises practical issues, treating them as identical methods can cause mistakes.
| Agreement | Persons Who May Be Declarants | Main Documents / Format of Statements | Details to Verify | Points of Caution |
|---|---|---|---|---|
| CPTPP | Exporter, producer, importer, etc. | Origin declaration, commercial documents fulfilling mandatory content, etc. | Information on exporter, producer, importer; description of goods; HS code; criteria for origin. | The declarant must retain documentation that can explain the origin. |
| Japan-EU EPA | Exporter, importer, etc. | Invoice or other commercial documents with an origin declaration statement, importer’s knowledge. | Origin declaration statement, country of origin, exporter reference number, correspondence to the goods. | Attention is required regarding the EU’s REX number and Japan’s corporate number. |
| RCEP | Approved exporter, exporter, producer, importer, etc. | Certificate of Origin, origin declaration, declaration by approved exporter, etc. | Eligible country, applicable period, certification method, country of origin, consecutive certificates of origin. | It is necessary to confirm available methods by country and by period. |
Origin Declaration and Origin Declaration Details
An origin declaration is the declaration itself, stating that the goods qualify as originating under the applicable agreement. Under the self-declaration system, the importer, exporter, or producer declares that the goods meet the requirements of the relevant agreement to be treated as originating.
Origin declaration details are supporting materials that organize the basis for the declaration, such as HS codes, Product-Specific Rules of Origin, raw materials, manufacturing processes, CTC analysis, RVC calculations, cumulation, and de minimis analysis. While the origin declaration is the actual declaration, origin declaration details explain why the goods qualify as originating.
| Item | Origin Declaration | Origin Declaration Details | Practical Notes |
|---|---|---|---|
| Role | Declares that the cargo is originating under the agreement. | Organizes the basis explaining why the goods qualify as originating. | Avoid the misunderstanding that origin can be proven by the declaration alone. |
| Main contents | Declarant, target cargo, country of origin, agreement, required description items, etc. | HS codes, PSR, raw materials, processes, CTC, RVC, cumulation, de minimis, etc. | Confirm consistency between the declaration and supporting documents. |
| Prepared by | Exporter, producer, importer authorized under the agreement. | Exporter, producer, importer, origin management personnel, etc. | Confirm in advance who holds the supporting documents. |
| Retained by | Declarant, importer, etc. | Declarant, importer, exporter, producer, etc. | Clarify retention responsibility in preparation for customs post-clearance verification. |
| Notes | Insufficient entries can hinder verification of preferential tariff rates. | Retain as evidence supporting the declaration in preparation for customs verification. | Do not treat the declaration and details as documents with the same role. |
Applicable Requirements and Non-Applicable Cases
To use the self-declaration system, it is necessary that the relevant agreement recognizes the self-declaration system, that the declarant is authorized under the agreement, and that the required information and supporting documents are properly prepared. Simply preparing the declaration form is not sufficient.
| Category | Applicable Requirements | Non-Applicable Cases and Common Issues | Practical Measures |
|---|---|---|---|
| Relevant agreement | The EPA or FTA in use must recognize the self-declaration system. | Agreements focused mainly on third-party certification, where only a self-declaration form is prepared. | Confirm the certification method specified by the relevant agreement. |
| Declarant | The declarant must be an entity recognized under the agreement, such as the exporter, producer, or importer. | Cases where an entity not recognized under the agreement makes the declaration. | Confirm on a case-by-case basis who is eligible to be the declarant under each agreement. |
| Required information | Meet the requirements specified in the agreement for information, wording, numbers, signatures, dates, etc. | Omissions or errors in the agreement name, country of origin, covered goods, exporter number, etc. | Verify the declaration text and declaration form against the requirements of each agreement. |
| Supporting documentation for origin | Be able to explain HS codes, PSR, CTC, RVC, process sheets, material lists, and similar evidence. | Only the declaration form is available and supporting documents are not retained. | Retain supporting documents in preparation for post-clearance customs verification. |
| Importer self-declaration | The importer must possess documents to explain the origin. | The importer cannot obtain documents from the exporter or producer. | Confirm the document acquisition framework before import. |
| Shipment criteria | Be able to demonstrate that originating goods did not lose eligibility during transport. | Instances of processing during transit through third countries, non-bonded storage, or unclear transport routes. | Check Bills of Lading, Sea Waybills, Air Waybills, and transit documentation. |
| Record-keeping obligation | Retain necessary documents according to the agreement and domestic laws. | Documents become untraceable due to personnel changes or system migration. | Clarify responsibilities, retention periods, and storage locations. |
| Post-import corrections and refunds | Verify whether procedures are possible according to the agreement, deadlines, submitted documents, and the situation at import declaration. | Assuming refunds can always be claimed afterward without prior confirmation at import. | Confirm before import declaration without relying on post-import remedies. |
Application Process Flow
The self-declaration system requires management not only at the stage of preparing the declaration form but also from the start of the transaction through to post-import verification. Confirm, in order, the applicable agreement, declarant, HS code, PSR, proof-of-origin documents, transportation route, and document retention.
| Step | Items to Confirm | Main Parties Involved | Decision to Proceed |
|---|---|---|---|
| 1 | Confirm the EPA or FTA to be used, such as CPTPP, the Japan-EU EPA, or RCEP. | Importer, exporter, customs broker | Confirm the certification method of the applicable agreement. |
| 2 | Check whether the self-declaration system can be used under that agreement. | Importer, exporter, customs broker | If not applicable, review alternative methods such as third-party certification. |
| 3 | Confirm who can act as the declarant: exporter, producer, or importer. | Importer, exporter, producer | Without identifying the declarant, the location of required documents cannot be confirmed. |
| 4 | Confirm the HS code of the applicable goods. | Importer, exporter, customs broker | Confirm the PSR based on the HS code. |
| 5 | Review the Product-Specific Rules of Origin. | Importer, exporter, producer | Decide how to explain origin: CTC, RVC, processing criteria, etc. |
| 6 | Organize supporting materials for origin. | Exporter, producer, importer | Check materials such as bill of materials, process charts, RVC calculation data, and supplier declarations. |
| 7 | Confirm cumulation rules, de minimis provisions, and shipment criteria. | Importer, exporter, freight forwarder, customs broker | Obtain transport documents or additional materials as needed. |
| 8 | Prepare and verify the origin declaration, origin declaration statement, and invoice details. | Declarant, trade operations personnel | Correct any omissions in required information. |
| 9 | Declare the application of preferential tariff rates at import declaration. | Importer, customs broker | Confirm that declaration details match the cargo content. |
| 10 | Retain documents for customs post-import verification. | Importer, exporter, producer | Clarify responsible party, retention period, and contact point for submission. |
Four-Column Decision Checklist
Under the self-declaration system, it is necessary to organize who should confirm what at each stage and how to respond if any issues arise. Management should cover not only whether a declaration form exists but also supporting documents and follow-up verification actions.
| Confirmation Stage | Party to Confirm | Items to Confirm | Response if Issues Arise |
|---|---|---|---|
| At start of transaction | Importer, exporter, sales representative | Applicable agreement, existence of preferential tariff rates, eligibility to use the self-declaration system. | If the agreement or certification method is unclear, organize details on the target country, HS code, and agreement name. |
| At confirming declaration entity | Importer, exporter, producer | Who among the exporter, producer, or importer can be the declarant. | If the declarant is unclear, verify the certification method of the relevant agreement. |
| At HS code verification | Importer, exporter, customs broker | HS code of the cargo, basis for classification, Product-Specific Rules of Origin. | If classification is unclear, check specification sheets or prior rulings. |
| At origin determination | Exporter, producer, importer | Applicability of CTC, RVC, processing criteria, cumulation rules, de minimis provisions. | If supporting documents are insufficient, confirm additional information with the producer or supplier before declaration. |
| At preparation of origin declaration or origin declaration statement | Declarant, trade operations personnel | Origin declaration, origin declaration statement, mandatory items, reference numbers, date. | If there are omissions or errors in the agreement name, correct them before import declaration. |
| When utilizing the Japan-EU EPA | Exporter, importer, customs broker | Origin declaration statement, exporter reference number, REX number, corporate number, importer’s knowledge. | If there are errors in numbers or wording, request correction from the exporter. |
| When utilizing RCEP | Importer, exporter, customs broker | Certification methods, target countries, applicable periods, country of origin, consecutive certificates of origin. | If eligibility for the self-declaration method is unclear, confirm the third-party certification method as well. |
| At transport arrangement | Exporter, importer, freight forwarder | Shipment criteria, transshipment through third countries, through Bills of Lading, transport routes. | If routed through third countries, confirm the necessity of transit documents or non-processing certificates. |
| At import declaration | Importer, customs broker | Preferential tariff declaration, declaration documents, consistency with cargo contents. | If documents are insufficient, avoid proceeding solely on the assumption that preferential tariff treatment will apply. |
| After import | Importer, exporter, producer | Record-keeping obligations, customs post-clearance verification, correction or refund possibilities. | Establish a system to submit records, and clearly define responsible personnel and storage locations. |
Main Documents
When using the self-declaration system, it is essential to manage the declaration documents together with supporting evidence explaining origin, transportation documents, and import declaration materials. It is important to decide in advance who will retain which documents.
| Documents / Materials | Purpose of Verification | Main Holders | Practical Notes |
|---|---|---|---|
| Origin declaration | Declare that the cargo is an originating product under the agreement. | Exporter, importer, producer | Confirm necessary details and consistency with the subject cargo. |
| Invoice or commercial document with origin declaration statement | Indicates origin through the declaration statement required by the agreement. | Exporter, importer | Verify wording, country of origin, exporter number, and correspondence with the cargo. |
| Origin declaration details | Organize evidence supporting origin. | Exporter, importer, producer | Retain as supplementary material supporting the origin declaration. |
| Invoice and Packing List | Verify cargo contents, quantities, prices, and transaction details. | Exporter, importer | Cross-check declarations against shipment documents. |
| HS code verification materials | Identify applicable cargo and Product-Specific Rules of Origin. | Importer, exporter, customs broker | Incorrect HS codes may lead to incorrect origin determination. |
| Product-Specific Rules of Origin reference | Confirm necessary origin criteria. | Importer, exporter, origin management staff | Note that requirements vary by agreement. |
| Raw material list / parts list / materials list | Distinguish originating and non-originating materials. | Producer, exporter | Verify consistency with materials actually used in production. |
| Manufacturing process chart | Confirm which processes were performed in which countries. | Producer, exporter | Subcontracted and intermediate processes are also subject to verification. |
| RVC calculation documents | Confirm compliance with regional value content criteria. | Producer, exporter, importer | Retain FOB price, non-originating material costs, and calculation formulas. |
| Supplier declarations | Confirm origin and value of materials. | Supplier, producer, exporter | Check applicable agreements, materials, and periods covered. |
| Materials origin documents when using cumulation | Verify materials subject to cumulation. | Supplier, producer, exporter | Do not treat materials purchased only from contracting countries as originating materials automatically. |
| Calculation support documents when using de minimis rules | Confirm whether non-originating materials are within tolerated limits. | Producer, exporter, importer | Check agreement-specified limits, values, and weights. |
| B/L, Sea Waybill, Air Waybill | Verify transport routes and shipment criteria. | Freight forwarder, shipping line, airline, importer | Additional documents may be required if third-country transit is involved. |
| Documents retained for customs verification | Explain origin in post-clearance verification. | Importer, exporter, producer | Retain declaration documents, supporting evidence, and transportation documents as a complete set. |
Common Practical Issues
In the self-declaration system, problems often arise not only from mistakes in preparing the declaration, but also from misidentifying the declarant, insufficient supporting documentation, misunderstanding certification methods under each agreement, and relying on post-import corrections or refunds.
| Case | Common Issues | Documents to Check | Practical Measures |
|---|---|---|---|
| Omission in origin declaration statement | The origin declaration statement lacks required information, causing delays in confirming eligibility for preferential tariff rates. | Agreement name, country of origin, exporter information, registration number, applicable goods | Cross-check the required information for each agreement before import declaration. |
| RVC calculation errors | A self-declaration is made despite not meeting regional value content criteria, and the issue cannot be explained during post-clearance verification. | FOB price, non-originating material value, RVC calculation documents | Verify calculation formulas and supporting documents before declaration. |
| Insufficient CTC documentation | Documentation comparing HS codes for finished goods and non-originating materials is missing, preventing explanation that change in tariff classification is met. | HS codes of finished goods and materials, material list, PSR | Organize HS codes by material and clarify the scope of non-originating materials. |
| Lack of evidence | Manufacturing process charts or raw material documents substantiating origin are not retained, making it impossible to respond to customs inquiries. | Process charts, material lists, supplier declarations, manufacturing records | Keep and store origin declarations together with all supporting documents. |
| Misunderstanding certification method under RCEP | Available methods by country and timing are not sufficiently confirmed when using self-declaration under RCEP. | Applicable country, certification method, applicable period, country of origin, consecutive certificates of origin | Confirm certification methods by exporting country, importing country, and timing. |
| Importer self-declaration without document acquisition | The importer makes a self-declaration but cannot obtain necessary information from exporters or producers. | Material lists, process charts, RVC calculation documents, cooperation framework with exporters and producers | Agree on the scope of document provision and contact points before import. |
| Confusion with the Authorized Exporter System | An exporter without authorization mistakenly believes they can declare using the Authorized Exporter System method. | Authorization number, authorization scope, applicable agreements, origin declaration statements on commercial documents | Confirm authorization status and applicable scope. |
| Relying on post-import refunds | The importer fails to verify requirements at import and expects preferential tariff application or refunds afterward. | Agreement deadlines, submission documents, circumstances at import declaration | Prepare necessary documents before import declaration and avoid relying on post-import remedies. |
Application Scenarios of the System
This section organizes typical challenging situations involving the self-declaration system into separate scenarios. The sequence of decisions, which can be difficult to grasp from tables alone, is confirmed along the actual business flow.
Scenario 1: Confusing the Authorized Exporter System with the Self-Declaration System
Exporters sometimes mistakenly believe they are using the Authorized Exporter System simply because they prepare the origin declaration statement themselves. However, the Authorized Exporter System applies only to exporters who meet specific requirements and receive authorization, allowing them to declare origin based on that authorization. Merely creating the declaration wording on their own does not mean they are utilizing the Authorized Exporter System.
This confusion can lead to issues such as missing the required authorized exporter number in transactions where it is mandatory, declaring non-eligible products, or incorrectly citing the applicable agreement. It is not possible to determine from the origin declaration statement on commercial documents alone whether the exporter is genuinely an authorized exporter.
In practice, when using the Authorized Exporter System, confirmation is needed of the authorization number, authorization scope, applicable agreements, eligible products, and the wording of the origin declaration statement. It is important not to treat the self-declaration system and the Authorized Exporter System as the same, but to clearly separate them as different certification methods under each agreement.
Scenario 2: When Importer Self-Declaration Fails to Obtain Materials from the Exporter or Producer
Under importer self-declaration, the importer declares origin themselves. However, explaining origin may require information held by exporters or producers, such as manufacturing processes, raw materials, HS codes, RVC calculation data, and supplier declarations.
If the importer is the declarant but the exporter or producer does not disclose cost or material information, it could become impossible to explain origin during customs post-clearance verification. Especially with RVC calculations, details about non-originating material values, FOB prices, and cost composition may be needed, making information-sharing arrangements with trade partners critical.
In practice, before using importer self-declaration, it is essential to confirm what documents can be obtained from exporters or producers, how confidential information is handled, and who will respond during customs verification. If the necessary documents cannot be obtained, proceeding on the assumption of importer self-declaration is not advisable.
Scenario 3: Misunderstanding the Certification Method under RCEP
RCEP involves multiple certification methods, including third-party certification, self-declaration by approved exporters, self-declaration by exporters or producers, and importer self-declaration. Which methods can be used depends on the exporting country, importing country, timing, and conditions set by the agreement.
If these factors are not verified and declarations are prepared assuming that the self-declaration system applies simply because the transaction is under RCEP, preferential tariff treatment may be denied by the importing country’s customs. Besides the self-declaration system, RCEP also involves other compliance points such as cumulation across a wide area, identification of the country of origin, consecutive certificates of origin, and shipment criteria.
In practice, when utilizing RCEP, confirm separately the target countries, applicable periods, available certification methods, countries of origin, consecutive certificates of origin, and shipment criteria. Do not judge solely by the certification method. These points should be organized as part of overall RCEP origin management.
Scenario 4: Confusing the Origin Declaration with Origin Declaration Details
The origin declaration is the document or statement declaring that the cargo qualifies as originating under the agreement. Origin declaration details are supporting materials explaining why the goods qualify as originating. Confusing these two can lead to the mistaken belief that preparing the declaration alone completes the explanation of origin.
For example, even if the origin declaration contains the necessary information, if HS codes for finished products and materials, Product-Specific Rules of Origin, CTC determinations, RVC calculations, production process charts, and supplier declarations are not retained, customs post-clearance verification may be unmanageable.
In practice, the origin declaration is treated as the actual declaration, while origin declaration details are treated as supporting evidence. Both should be managed as a set. If the personnel preparing the declaration differ from those maintaining the origin evidence, it is necessary to clarify storage locations and responsible individuals.
Scope of Freight Forwarder Involvement
In the self-declaration system, freight forwarders may verify the consistency of documents such as invoices, packing lists, B/L, Sea Waybill, and Arrival Notices, and may assist with customs clearance procedures. They may also help organize transportation documents necessary for confirming shipment criteria.
However, freight forwarders are generally not the responsible party for determining the origin of the cargo itself. Origin determination requires information such as HS codes, raw materials, manufacturing processes, cost calculations, and supplier details, which should be managed by importers, exporters, or producers.
| Category | Tasks Suitable for Support | Tasks Not to Conclude | Practical Approach |
|---|---|---|---|
| Shipping documents | Check for consistency among invoice, Packing List, B/L, and Sea Waybill. | Final determination of whether the cargo qualifies as originating under the agreement. | If there are document discrepancies, prompt importers, exporters, and customs brokers to check. |
| Origin declaration or origin declaration statement | Formally confirm the presence of origin declarations or origin declaration statements. | Guarantee that the declaration content meets the Product-Specific Rules of Origin. | Verify required information is present and prompt the cargo owner to confirm the origin determination. |
| Shipment criteria | Organize transportation documents such as B/L, Sea Waybill, and transshipment records. | Legally conclude that shipment criteria under the agreement are met. | Arrange transportation route documentation and share it with customs brokers. |
| Facilitating confirmation with cargo owners | Encourage importers, exporters, and producers to verify HS codes, PSR, and supporting documents. | Decide on the fulfillment of CTC, RVC, or processing criteria. | Items requiring origin determination should be confirmed with cargo owners, customs brokers, and experts. |
| Preparing for customs verification | Organize transportation-related and customs-related documents. | Guarantee that origin will be accepted in customs post-clearance verification. | Separate the locations of transport documents and origin-related documents for verification. |
| Schedule management | Share timing of import declarations, document arrival, and customs clearance plans. | Guarantee that declaration documents will always be accepted or preferential tariff rates granted. | If documents are insufficient, share this information promptly with relevant parties before import declaration. |
Points to Note
When using the self-declaration system, it is important to note that whether the system can be used depends on the specific agreement. Who is eligible to be the declarant, whether the exporter, producer, or importer submits the declaration, and what information must be included in the origin declaration or origin declaration statement all vary by agreement.
If there are omissions or errors in the content of the origin declaration or origin declaration statement, preferential tariff rates may be denied. Additionally, the declaration alone is insufficient; supporting documentation based on criteria such as CTC, RVC, or processing requirements must also be retained.
There are deadlines and conditions for corrections or refunds after import. Neglecting necessary verifications at the time of import declaration and assuming corrections can be made later is risky. Under the self-declaration system, confirming details before import declaration and retaining documentation to respond to customs post-clearance verification are crucial.
Freight forwarders can assist with document consistency checks and organizing transportation records, but they are not responsible for origin certification. The judgment of origin should not be entirely delegated to the freight forwarder; importers, exporters, producers, and customs brokers must share responsibilities and perform the necessary verification.
Summary
The self-declaration system is an origin certification framework under which exporters, producers, or importers declare themselves that the goods qualify as originating products under the agreement. Compared with the third-party certification system, it allows for faster procedures; however, the declarant must manage documents that can justify the origin claim.
Whether the self-declaration system can be used, who can act as the declarant, and which documents are required differ depending on the agreement, such as CPTPP, the Japan-EU EPA, or RCEP. It is important to keep it clearly distinguished from the Authorized Exporter System, the REX System, and importer self-declaration.
In actual practice, it is necessary to verify not only the wording on the origin declaration or origin declaration statement but also HS codes, Product-Specific Rules of Origin, CTC, RVC, processing criteria, cumulation rules, de minimis provisions, shipment criteria, supporting documents, and customs post-clearance verification as an integrated process.
While the self-declaration system is convenient, if used without properly preparing supporting evidence, preferential tariff treatment could be denied during later customs verification. It is essential to manage origin declarations and supporting evidence separately, and clearly define the responsibilities for declaration and document retention in daily operations.
