Certificate of Origin — Preferential vs. Non-Preferential Certification Practice
Interlink編集部What Is a Certificate of Origin?
A certificate of origin is a document that indicates the country or region where cargo is considered to have originated.
In international trade, a certificate of origin goes beyond simple origin labeling. It is relevant to customs duties, preferential tariff rates under EPAs and FTAs, the Generalized System of Preferences (GSP), import restrictions, origin marking requirements, anti-dumping measures, letter of credit conditions, and submission requests from trading partners.
There are two main types of certificates of origin: preferential certificates of origin used to apply for preferential tariff rates under EPAs and FTAs, and non-preferential certificates of origin used for purposes unrelated to tariff preferences.
Although both are called certificates of origin, the relevant systems, required documents, certification methods, and responsible parties differ depending on the intended purpose. In practice, origin certification requires confirming not only the presence of a certificate of origin but also the HS code, Product-Specific Rules of Origin, Change in Tariff Classification criteria, Regional Value Content criteria, processing criteria, cumulation provisions, de minimis rules, shipment criteria, and the certification method as an integrated process.

Reasons Why Certificates of Origin Are Required
Certificates of origin are used to verify the country or region where cargo is considered to have originated.
In particular, when applying preferential tariff rates under EPAs or FTAs, it is essential to demonstrate that the cargo qualifies as originating under the relevant agreement. Without this, preferential tariff treatment cannot be granted.
Additionally, certificates of origin are relevant not only for preferential tariffs but also for anti-dumping duties, safeguard measures, import quantity restrictions, country of origin labeling, trade statistics, letter of credit conditions, and verification requests from trading partners.
Therefore, certificates of origin are not merely supporting documents but are critical practical documents directly linked to customs duties, customs clearance, trading terms, and regulatory compliance.
Purpose and Background of the System
The purpose of the origin certification system is to enable verification of the cargo’s country of origin, facilitating proper handling of customs duty rates, preferential tariffs, trade controls, origin labeling, and conditions in trading documents.
Under preferential schemes such as EPAs and FTAs, it is necessary to restrict benefits to the intended partner countries and eligible products. Granting preferential tariff rates simply because goods are shipped from an agreement country may lead to circumvention or abuse, such as diverting goods originating from third countries.
Meanwhile, general certificates of origin or non-preferential certificates of origin may be used not for preferential tariff purposes, but for submission to trading partners, compliance with letter of credit terms, origin labeling, import controls, or anti-dumping measures.
Therefore, when verifying a certificate of origin, the starting point should be to clarify the purpose for which the certification is being obtained.
Key Situations Where Origin Certification Applies
| Situation | Certificates / Documents Used | Main Parties Involved | Practical Points to Note |
|---|---|---|---|
| Import Declaration Using EPA/FTA Tariff Rates | Specified certificates of origin, origin declarations, origin declaration statements, etc. | Importer, exporter, producer, customs broker | Supporting evidence that meets origin criteria is required in addition to certificates |
| Import Declaration Using GSP Tariff Rates | GSP certificates of origin such as Form A | Importer, exporter, issuing authority, customs broker | Confirm eligible countries, applicable products, and direct shipment requirements as a system separate from EPA |
| Submission of General Certificates of Origin | General certificates of origin issued by Chambers of Commerce, etc. | Exporter, Chamber of Commerce, trading partner | These certificates may not qualify for preferential tariff treatment |
| Compliance with Letter of Credit Conditions | Certificate of Origin, commercial documents, shipping documents | Exporter, bank, trading partner, freight forwarder | Verify consistency between L/C terms and certificate contents |
| Origin Marking | Supporting documents for marking, manufacturing process records, general certificates of origin, etc. | Importer, seller, manufacturer | Do not confuse the declared country of origin with preferential origin certification |
| Anti-Dumping Measures and Countervailing Duties | Country of origin documents, manufacturing country records, transaction documents | Importer, customs broker, trade compliance personnel | Check whether the product is subject to measures for the concerned country |
| Customs Post-Verification | Certificates of origin, origin declarations, bill of materials, process flow charts, cost records, transport documents | Importer, exporter, producer, customs broker | Maintain and be able to explain supporting documents even after declaration |
Common Misunderstandings
The following misunderstandings frequently occur regarding certificates of origin.
| Misunderstanding | Actual Consideration | Potential Issues |
|---|---|---|
| Having a certificate of origin means the origin criteria are satisfied | While the certificate is important, customs may require supporting documents proving compliance with origin criteria | Lack of evidence may prevent explanation for preferential tariff application |
| The country of manufacture is automatically the country of origin | The country of manufacture and the country of origin do not always coincide; determination should follow the rules of origin | Incorrect origin may be declared for products containing materials from third countries |
| The country of shipment is the country of origin | The country of shipment indicates the export or transit location, which can differ from the product’s origin | Transshipment locations or ports of export may be confused with the country of origin |
| Freight forwarders can issue certificates of origin | Freight forwarders assist with document coordination and transport paperwork but generally are not parties certifying origin | Origin certification may be mistakenly treated as complete based on transport documents alone |
| A general certificate of origin can be used for EPA tariff rates | General certificates of origin are often for non-preferential purposes; EPA tariffs require agreement-specific certification methods | Failure to prepare required preferential origin certification results in standard tariff rates |
| GSP and EPA certificates of origin are the same | GSP is a separate system from EPA/FTA, with different eligible countries, products, certificates, and direct shipment requirements | Submitting under the wrong scheme may cause denial of preferential tariff treatment |
| An origin declaration alone suffices for post-clearance verification | Additional supporting documents, such as material lists, processing records, cost data, and transport documents, may be required | Failure to substantiate origin during post-clearance verification can lead to loss of preferential tariff benefits |
| A certificate once obtained can be used for subsequent shipments without change | Reconfirmation is needed if materials, manufacturing processes, HS codes, suppliers, prices, or transport routes change | Relying on past certificates for current cargo may result in mismatched or invalid certification |
Preferential and Non-Preferential Certificates of Origin
Certificates of origin can generally be categorized into preferential and non-preferential types.
Preferential certificates of origin are used to apply preferential tariff rates under agreements such as EPAs and FTAs. In these cases, the certificate of origin, origin declaration, or origin declaration statement is used to demonstrate that the cargo qualifies as originating goods under the agreement.
Non-preferential certificates of origin are used separately from tariff preferences to address import regulations, origin labeling, anti-dumping duties, letter of credit requirements, or client requests.
In practice, when a trading partner requests a certificate of origin, it is important to first confirm whether it is intended for EPA preferential tariff treatment, GSP usage, or a general certificate of origin.
Differences Between Preferential and Non-Preferential Certificates of Origin
| Item | Preferential Certificate of Origin | Non-Preferential Certificate of Origin | Practical Notes |
|---|---|---|---|
| Main Purpose | To apply preferential tariff rates under EPAs, FTAs, GSP, and similar systems | To comply with origin marking, letter of credit conditions, import regulations, anti-dumping duties, and customer requirements | First verify the purpose of the certification |
| Main Certificates and Documents | Specified certificates of origin, origin declarations, origin declaration statements, GSP certificates, etc. | General certificates of origin, trade-related certificates issued by Chambers of Commerce, etc. | Even if document names are similar, the applicable system differs |
| Rules to Confirm | Preferential rules of origin under the relevant agreement, PSR, shipment criteria, certification methods | Non-preferential origin rules, trade terms, marking regulations, import country requirements | Do not confuse origin determination for preferential use with country of origin marking |
| Situations Where Used for Determination | Import declarations applying EPA, FTA, or GSP tariff rates | Letter of credit conditions, submission to business partners, origin marking, trade controls, AD duty response, etc. | Distinguish whether the certificate is for import declaration or for transactional documentation |
| Required Supporting Materials | HS codes, PSR, material lists, processing charts, RVC calculations, shipment documents | Manufacturing country information, commercial documents, marking basis, customer requirement documentation | Retain not only the certificate but also supporting evidence |
| Points of Caution | Supporting materials proving compliance with origin criteria are required, not just the certificate | Certificates do not necessarily qualify goods for preferential tariff treatment | Do not rely solely on the term “Certificate of Origin” for judgment |
Comparison of EPA, FTA, GSP, and General Certificates of Origin
It is important not to confuse EPA/FTA, GSP, and general certificates of origin in origin certification.
| System / Document | Main Purpose | Typical Certificates / Declarations | Contents to Verify | Practical Notes |
|---|---|---|---|---|
| EPA / FTA | To apply preferential tariff rates under trade agreements | Specified Certificate of Origin, origin declaration, origin declaration statement, etc. | Applicable agreement, HS code, PSR, CTC, RVC, processing criteria, shipment criteria | Certification methods and required documents vary by agreement |
| GSP | To apply general preferential tariff rates to eligible goods from developing countries | GSP Certificate of Origin, Form A, etc. | Eligible countries, eligible goods, GSP rules of origin, direct shipment requirements, certificate validity | GSP should be confirmed as a separate system from EPA |
| General Certificate of Origin | For submission to trading partners, L/C conditions, and non-preferential origin confirmation | General Certificate of Origin issued by Chambers of Commerce, etc. | Country of manufacture, country of origin, transaction documents, requirements from the submitting party | Does not necessarily qualify as a certificate for EPA preferential tariff rates |
| Origin Marking / Trade Control | For compliance with marking, import restrictions, AD duties, countervailing duties, and similar measures | Legal basis documentation by system, manufacturing data, marking justification documents | Non-preferential origin, applicable measures, marking systems, regulations of the importing country | May require separate judgment from preferential origin certification |
Applicable Requirements and Common Exceptions
| Check Items | Requirements for Application | Common Exceptions and Problematic Situations | Practical Responses |
|---|---|---|---|
| System Identification | Specify whether the certificate is for EPA/FTA, GSP, a general certificate of origin, or a non-preferential purpose | Proceeding based only on the trading partner’s instruction that “C/O is required” | Confirm the purpose of submission, submitting party, applicable tariff rate, and system name |
| HS Code | Confirm the HS code of the cargo involved | Confirming only the certification method without clarifying the HS code | Check classification materials and consult the customs broker or experts if necessary |
| Origin Criteria | Comply with PSR, CTC, RVC, processing criteria, etc. | Deciding origin based solely on the manufacturing country or shipping country | Verify bill of materials, process charts, and cost records |
| Certification Method | Use a certification method accepted under the applicable system | Attempting to apply EPA tariff rates with a general certificate of origin | Check for each agreement the acceptance of third-party certification, self-certification, or importer self-declaration |
| Shipment Criteria | Meet direct shipment or third-country transit requirements | No through B/L or bonded storage documents when shipped via a third country | Confirm the transport route and required documentation before shipment |
| Retention of Supporting Documents | Retain documents sufficient for customs verification | Keeping only the certificate without bills of materials or process charts | Determine document retention responsibilities among importer, exporter, and producer |
The Country of Origin Is Not Simply the Country of Manufacture
The country of origin is not always determined solely by the country where the final processing was done or the country from which the goods were shipped.
When parts procurement, processing, and assembly occur across multiple countries, the country of origin must be determined according to the applicable rules of origin.
For example, even if parts from a third country are assembled in Japan, the goods may not automatically qualify as Japanese-origin products. It is necessary to verify whether the product meets the Product-Specific Rules of Origin, whether a tariff classification change has occurred, whether Regional Value Content criteria are satisfied, and whether the required processing steps have been performed.
Therefore, statements such as “made in Japan,” “imported from the EU,” or “assembled in China” alone are insufficient as proof of origin. It is important to clearly explain under which origin system and criteria the goods qualify.
Main Items to Verify with Origin Certification
Origin certification primarily involves verifying the following items.
- Which system is applied: EPA, FTA, GSP, or general origin certification
- HS code of the applicable cargo
- Product-Specific Rules of Origin
- Change in Tariff Classification criteria
- Regional Value Content criteria
- Processing criteria
- Eligibility for cumulation systems
- Applicability of the de minimis rule
- Shipment criteria
- Certification method
- Status of supporting document retention
These items are verified not only individually but also in relation to each other. For example, if the Product-Specific Rules of Origin require the CTC criterion, and some non-originating materials fail to meet the standard, it should be confirmed whether the de minimis rule can be applied. Additionally, even if the origin criteria are fulfilled, failure to meet shipment criteria when routing through a third country may affect the application of preferential tariff rates.

Main Methods of Origin Certification
The methods for origin certification vary depending on the system or agreement. Common methods include third-party certification, exporter self-declaration, producer declaration, and importer self-declaration.
Which method can be used depends on the applicable agreement, the countries involved, and the importing country's system. Confirmation of whether the cargo meets the origin criteria and which certification method to use should be conducted simultaneously.
Comparison of Certification Methods
| Certification Method | Issuing Entity | Suitable Situations | Points to Note |
|---|---|---|---|
| Third-Party Certification System | Issuing authorities such as Chambers of Commerce | When using a system where the issuing authority provides the certificate | Confirm application procedures, issuance lead time, certificate contents, and retention of supporting documents |
| Exporter Self-Declaration | Exporter | When the exporter can verify origin and include an origin declaration statement on commercial documents | The exporter needs to retain documents that can explain the origin |
| Producer Declaration | Producer | When the producer has knowledge of manufacturing processes, raw materials, and cost information | If the exporter lacks manufacturing information, producer documents become crucial |
| Importer Self-Declaration | Importer | When the importer can obtain and manage supporting origin documents | The importer must hold documents sufficient to respond to customs verification |
| General Certificate of Origin | Issuing authorities such as Chambers of Commerce | When a certificate of origin is required for counterparties, L/C terms, or non-preferential purposes | May differ from certification methods used for EPA tariff rates |
Main Documents Required for Origin Certification
For origin certification, not only the certificate itself but also supporting materials that verify the origin are important.
| Document | Purpose of Verification | Main Holders | Points to Note |
|---|---|---|---|
| Certificate of Origin | To demonstrate that the goods are originating under third-party certification systems and similar frameworks | Exporter, issuing authority, importer | Check the issue date, validity period, contents, and consistency with the invoice |
| Origin Declaration | To declare origin under a self-declaration system | Exporter, importer, producer | Confirm that the declarant possesses the supporting documentation |
| Invoice or Commercial Document Containing an Origin Declaration Statement | To indicate origin through a declaration statement recognized under the agreement | Exporter, importer | Verify conformity with the agreement’s prescribed wording and requirements |
| HS Code Verification Documents | To identify the applicable cargo and corresponding Product-Specific Rules of Origin | Importer, exporter, customs broker | Misclassification of tariff codes leads to incorrect origin determination |
| Product-Specific Rules of Origin Verification Documents | To confirm which origin criteria must be met | Importer, exporter, customs broker | Criteria required may differ by agreement |
| Raw Material List, Parts List, or Material Sheet | To verify the materials used and their origin | Producer, exporter | Manage originating and non-originating materials separately |
| Production Process Chart | To confirm which processes were performed and where | Producer, exporter | Must be able to explain that processing was more than minimal |
| RVC Calculation Documents | To demonstrate compliance with Regional Value Content criteria | Producer, exporter, importer | Consistency between FOB price, material costs, and cost records is crucial |
| Supplier Certificates | To verify the origin and value of materials | Supplier, producer, exporter | Especially important when using cumulation systems |
| Transport Documents such as B/L, Sea Waybill, or Air Waybill | To confirm shipment criteria and transportation routes | Freight forwarder, carrier, importer | When routed via a third country, a through B/L or transshipment documentation may be required |
| Retention of Documentation for Customs Verification | To explain the origin in post-clearance verification | Importer, exporter, producer | Maintain documents in a state ready for submission after declaration |
Post-Clearance Verification by Customs
When using preferential tariff rates under EPA, FTA, or similar agreements, customs may conduct a post-clearance verification of origin after importation. This process is often called post-clearance verification, verification, or origin investigation.
During customs verification, you may be required to submit or explain not only the certificate of origin or origin declaration but also the HS code, Product-Specific Rules of Origin, raw materials, manufacturing processes, RVC calculations, supplier certifications, transportation documents, and other related materials.
If the necessary documents are not retained or supporting materials for the declared information cannot be presented, the application of preferential tariff rates may be disallowed.
Documents Often Requested for Post-Verification
| Item to Be Verified | Commonly Requested Documents | Purpose of Verification | Risks if Documents Are Lacking |
|---|---|---|---|
| HS Code | Classification materials, catalogs, ingredient lists, specifications | To confirm the correct application of Product-Specific Rules of Origin | The applied origin criteria might be incorrect |
| Origin Criteria | PSR verification documents, decision tables, certificates of origin, origin declarations | To verify which criteria were used to determine originating status | Inability to explain origin may lead to denial of preferential tariff rates |
| Origin of Materials | Material lists, parts lists, supplier certificates, raw material documentation | To distinguish between originating and non-originating materials | Unable to substantiate cumulation or classification as originating materials |
| CTC | Finished product HS code, material HS codes, classification justification documents | To confirm compliance with tariff classification change requirements | Unable to explain compliance with HS code changes |
| RVC | FOB price documents, value of non-originating materials, cost data, RVC calculation sheets | To verify fulfillment of Regional Value Content criteria | Lack of calculation basis may prevent explanation of RVC compliance |
| Processing Criteria | Manufacturing process charts, production records, work instructions, subcontractor documents | To confirm that required processing operations were performed | Risk of being judged as having undergone only minor processing |
| Shipment Criteria | B/L, Sea Waybill, through Bill of Lading, transit documentation, bonded storage records | To verify that originating status was maintained during transit via third countries | Unable to substantiate maintenance of originating status during transport |
Initial Response When Receiving Post-Verification
| Verification Stage | Party to Confirm With | Items to Confirm | Actions If Issues Are Found |
|---|---|---|---|
| Immediately After Customs Inquiry | Importer, customs broker | Relevant declaration, subject cargo, applicable agreement, submission deadline | Create a deadline management chart and prioritize submission documents accordingly |
| Verification of Documentation | Importer, customs broker, exporter | Certificate of Origin, origin declaration, invoice, packing list | If discrepancies exist, confirm whether corrections or supplementary explanations are possible |
| Confirmation of Rules of Origin | Exporter, producer, importer | Whether to explain based on CTC, RVC, processing criteria, cumulation, or de minimis | If supporting documents are insufficient, request additional materials from producers or suppliers |
| Verification of Transport Route | Freight forwarder, customs broker, importer | Direct shipment, third-country transit, transshipment, bonded storage, through Bill of Lading | Obtain transit point records, transshipment logs, and bonded storage documents to the extent possible |
| Organizing Response Content | Importer, customs broker, experts as needed | Explanations for customs inquiries, attached documents, reasons for any documents not submitted | Do not provide speculative answers; offer supplementary explanations or conduct further confirmation |
| Review Impact on Past Declarations | Importer, customs broker, finance and trade compliance departments | Past declarations involving the same product, supplier, and agreement | If similar issues arise, consider reviewing and taking additional measures on past declarations |
Freight Forwarders’ Scope of Involvement
Freight forwarders are neither the issuing party of certificates of origin nor the party responsible for determining origin status itself.
Determining origin requires information such as HS codes, manufacturing processes, raw materials, cost calculations, and supplier details, which should be managed by importers, exporters, and producers.
Meanwhile, freight forwarders are positioned to verify the consistency of documents such as invoices, packing lists, Bills of Lading, Sea Waybills, and arrival notices, as well as to check for the presence or absence of certificates of origin or origin declarations. They may also assist with organizing transportation documents related to shipment criteria.
What Freight Forwarders Can Support and What They Should Not Decide
| Item | What Freight Forwarders Can Support | What Freight Forwarders Should Not Decide | Practical Approach |
|---|---|---|---|
| Transport Documents | Verification of B/L, Sea Waybill, Air Waybill, and Arrival Notice | Final determination whether the cargo qualifies as originating under the agreement | Confirm consistency of transport documents; origin determination should be confirmed by importer, exporter, or manufacturer |
| Certificate of Origin | Presence of certificate, consistency with shipping documents, formal check of stated information | Guarantee that the certificate meets origin criteria | If discrepancies are found, promptly share them with the shipper and customs broker |
| Shipment Criteria | Organizing documents related to direct shipment, transshipment, third-country routing, and through Bills of Lading | Legal judgment on whether shipment criteria under the agreement are satisfied | Arrange necessary transport documents; final judgment is made by the importer or customs broker |
| Customs Preparation | Check for the presence of the invoice, packing list, and origin-related documents | Assessment of whether PSR, CTC, RVC, or processing criteria are fulfilled | If documents are missing, request additional information from the exporter or importer |
| Guidance to Cargo Owners | Advise exporters, importers, and manufacturers on documents they should confirm | Guarantee of origin based on cost data or manufacturing processes | Clearly separate guidance on confirmation documents from origin determination |
| Post-Verification Support | Assist in re-acquiring transport route records, transshipment logs, B/L, Sea Waybill, etc. | Substantive judgment on origin in response to customs inquiries | Organize transport-related documents; explanations regarding origin criteria should be supplemented with documents from the cargo owner |
In freight forwarding practice, it is safer to position the forwarder as a supporter for preparing necessary documents, transport routes, customs procedures, and responses to customs verification, rather than making definitive calls on whether EPA preferential tariff rates apply.
Practical Workflow for Verifying Certificates of Origin
- Confirm the reason why a certificate of origin is required
- Determine whether a general certificate of origin or a preferential certificate of origin is needed
- Identify the system to be used, such as EPA, FTA, or GSP
- Check the HS code of the relevant cargo
- Review the Product-Specific Rules of Origin
- Confirm whether to explain origin based on CTC, RVC, or processing criteria
- Verify if the cumulation system can be applied
- Check whether the de minimis rule applies
- Confirm whether the shipment meets shipment criteria
- Identify the available certification methods
- Prepare certificates of origin, origin declarations, or origin declaration statements
- Retain documentation supporting the origin claim
- Prepare for potential customs post-clearance verification
Checklist for Decision Points
Origin certification should not be checked only immediately before import declaration or submission of the certificate. It needs to be managed as a continuous process from the start of the transaction through customs post-verification.
| Checkpoint | Parties to Confirm | Items to Confirm | Actions if Issues Are Found |
|---|---|---|---|
| At Transaction Initiation | Importer, exporter, sales representative | Reasons for needing origin certification, customer requirements, use of EPA, FTA, or GSP | If the purpose of submission is unclear, verify the intended use with the customer or customs broker |
| At HS Code Confirmation | Importer, exporter, customs broker | HS code of the cargo, classification, Product-Specific Rules of Origin | If classification is uncertain, consider advance rulings or expert verification |
| At Origin Determination | Exporter, producer, importer | Applicability of CTC, RVC, processing criteria, cumulation, and de minimis | If bills of materials, cost data, or process charts are lacking, defer preference utilization |
| At Certification Method Confirmation | Exporter, importer, customs broker | Whether to use third-party certification, exporter self-declaration, producer declaration, or importer self-declaration | If using a certification method inconsistent with the system, review the certificate or declaration method |
| At Transportation Arrangement | Exporter, importer, freight forwarder | Shipment criteria, direct shipment, third-country transit, transshipment, transport documents | For third-country transit, verify through B/L, transit documents, and bonded storage records |
| At Import Declaration | Importer, customs broker | Eligibility for preferential tariff rates, validity of certificate, consistency with cargo | If discrepancies are found, consider correction, replacement, or switching to the standard tariff declaration |
| At Customs Post-Verification | Importer, exporter, producer | Compliance with origin criteria, supporting evidence, materials, processes, costs, shipment criteria | If documentation is insufficient, obtain additional materials, provide supplementary explanations, or review past declarations |
Common Issues with Origin Certification
| Situation | Typical Issues | Documents to Verify | Practical Measures |
|---|---|---|---|
| Difference between Manufacturing Country and Origin | Goods assembled in Japan using parts from a third country may fail to meet Product-Specific Rules of Origin and thus cannot be treated as Japanese-origin goods | HS code, PSR, CTC, RVC, processing workflow documents | Do not rely solely on manufacturing country; verify according to the origin rules of the relevant system |
| Non-Use of EPA | Preferential EPA tariff rates are not applied because origin certification was not prepared despite the cargo qualifying under EPA | Applicable agreement, preferential tariff rates, certification methods, required documents | Confirm EPA eligibility and availability of certification documents at the start of the transaction |
| Insufficient GSP Verification | Failure to confirm whether the cargo qualifies under GSP by country and product, or to check for necessary origin certification, resulting in loss of preferential treatment | Covered countries, covered products, GSP rules of origin, direct shipment requirements | Check GSP eligibility conditions separately from EPA |
| Incorrect HS Code | Origin determination based on an incorrect HS code, leading to post-fact discovery of errors in verifying Product-Specific Rules of Origin | Product classification documents, advance rulings, PSR verification documents | Confirm or finalize HS code before preparing origin certification |
| Insufficient RVC Documentation | Regional Value Content criteria are used but the party cannot provide cost documents or the value of non-originating materials | FOB price, value of non-originating materials, cost data, RVC calculation sheets | Keep calculation rationale and decide document submission scope among importer, exporter, and producer |
| Omission of De Minimis Verification | Some non-originating materials fail CTC, but the applicability of the de minimis rule is not checked | Material prices, weights, agreement-specific eligibility, PSR verification documents | Confirm applicability of the de minimis rule by agreement and product |
| Insufficient Shipment Documentation | Although goods qualify as originating, there is a lack of supporting documents explaining bonded control or non-processing during transit through third countries | B/L, through B/L, transit documents, bonded storage records, transshipment logs | For third-country transit, confirm necessary transport documents before shipment |
| Inadequate Response to Customs Verification | Origin declarations are present, but manufacturing process charts and material documents are not retained, hindering response to post-clearance verification | Complete set of retained documents, material lists, process charts, cost data, supplier certificates | Keep documents from the declaration stage anticipating potential post-clearance verification |
Application Scenarios for the System
Scenario 1: Misunderstanding that a General Certificate of Origin Allows Use of EPA Tariffs
There are cases where exporters obtain a general certificate of origin from a Chamber of Commerce because the trading partner requests its submission, leading importers to mistakenly believe this document permits application of EPA tariff rates.
However, general certificates of origin are often used for submission to trading partners, meeting letter of credit conditions, or confirming non-preferential origin, and may differ from preferential certificates of origin required for applying EPA tariff rates.
In such cases, it is important first to confirm the purpose of submitting the certificate. If the EPA tariff rate is to be applied, the certificate or declaration format recognized by the relevant agreement, such as a specified certificate of origin, origin declaration, or origin declaration statement, should be checked.
Scenario 2: Determining Origin Solely by Manufacturing Country
Sometimes, origin certification is prepared on the assumption that goods assembled in Japan qualify as Japanese origin.
However, if parts from third countries are used, merely assembling the product in Japan may not meet the criteria to be recognized as originating under the agreement. When Product-Specific Rules of Origin require criteria such as CTC, RVC, or processing criteria, each standard must be confirmed as satisfied.
In these cases, it is essential to check the HS code, bill of materials, process flow chart, and RVC calculation documents to clearly identify under which origin criterion the goods qualify as originating.
Scenario 3: Confusing GSP with EPA
There are cases where importers assume preferential tariff treatment applies for imports from developing countries without distinguishing between GSP and EPA, leading to incorrect preparation of origin documents.
The GSP is a separate system from EPA/FTA, with differences in eligible countries, covered products, origin criteria, required certificates, and direct shipment requirements. Certificates of origin or origin declarations prepared for EPA may not satisfy GSP requirements.
In practice, it is advisable to first check the MFN tariff rate, then decide whether to use EPA/FTA, GSP, or declare under normal tariffs. Once the system to be applied is determined, confirming the necessary origin documentation format ensures accuracy and compliance.
Scenario 4: Failure to Submit Supporting Documents during Post-Verification
While an importer may submit an origin declaration at import and apply the EPA tariff rate, there have been cases where the importer cannot present supporting documents such as bills of materials, process flow charts, or cost data during subsequent customs post-verification.
Possession of certificates of origin or origin declarations alone does not always suffice. Customs requires explanations on which origin criteria are met and on what evidence this is based.
To mitigate this risk, it is critical at the time of declaration to establish clear agreements among the importer, exporter, and manufacturer regarding the scope of retained documentation. Also, it is important to have systems in place to obtain supplier certificates or manufacturing process records as needed.
Practical Checklist
When verifying certificates of origin, confirm the following points:
- Whether the reason for requiring the certificate of origin has been identified
- Whether the certificate is for preferential or non-preferential origin
- Which certificate to use among EPA, FTA, GSP, or general certificates of origin
- Whether the HS code for the cargo concerned has been checked
- Whether the Product-Specific Rules of Origin have been reviewed
- Whether the origin explanation is based on CTC, RVC, or processing criteria
- Whether the applicability of cumulation rules or the de minimis provision has been confirmed
- If the cargo is routed through a third country, whether shipment criteria have been verified
- Whether the available certification methods have been confirmed
- Whether it has been determined which document is needed: certificate of origin, origin declaration, or origin declaration statement
- Whether supporting documentation for origin determination is retained
- Whether document management is adequate to respond to post-clearance customs verification
- Whether origin determination responsibility is not entirely delegated to the freight forwarder
Summary
Origin certification is the practical process of demonstrating the country or region where cargo is treated as originating.
It is closely related to preferential tariff rates, non-preferential origin, GSP, import restrictions, origin marking, anti-dumping measures, and significantly affects customs duties and clearance decisions.
In practice, it is important to verify not only the presence of a certificate of origin but also the HS code, Product-Specific Rules of Origin, CTC, RVC, processing criteria, cumulation systems, de minimis provisions, shipment criteria, and certification methods.
Origin certification does not end with document submission. It also requires managing the retention of supporting evidence to respond to customs verification.
When handling certificates of origin, it is essential first to confirm their purpose and avoid confusing preferential certificates of origin, non-preferential certificates of origin, GSP certificates, and general certificates of origin.
