Hazardous Materials Declaration Form
Interlink編集部What Is a Dangerous Goods Declaration?
A Dangerous Goods Declaration is a document used to declare to the carrier the hazards, classification, packaging, quantity, markings, and transport conditions of cargo classified as dangerous goods. In maritime transport, it may be called a Dangerous Goods Detail Statement, Dangerous Goods Declaration (DGD), or Multimodal Dangerous Goods Form. For air transport, the Shipper’s Declaration for Dangerous Goods is used.
In freight forwarder operations, the Dangerous Goods Declaration serves as a core document for dangerous goods bookings, carrier acceptance confirmation with shipping lines or airlines, CFS and warehouse in-gate, airline confirmation, and document verification. If the declaration does not align with the SDS, invoice, packing list, actual cargo labels, or external markings, this may lead to in-gate refusal, shipping delays, or rejection of air carriage.
The Dangerous Goods Declaration is not merely a supporting document. It is a fundamental operational resource used to determine whether the dangerous cargo can be safely transported, whether shipping lines, airlines, and warehouses can accept it, and how to respond in case of an emergency.
Freight forwarders should not simply forward the Dangerous Goods Declaration as received. They must cross-check it against the SDS, invoice, packing list, actual cargo markings, transport mode, and the carrier’s acceptance criteria. If any clear discrepancies or omissions are identified, the freight forwarder should confirm details with the shipper.

Role of the Dangerous Goods Declaration
The purpose of the Dangerous Goods Declaration is to accurately communicate hazardous cargo information to all parties involved in transportation. It includes details such as the UN number, proper shipping name, hazard class, packing group, quantity, packaging, labels, marks, marine pollutant status, and emergency contact information.
In hazardous materials transport, shipping lines, airlines, warehouses, CFS, trucking companies, and customs brokers verify acceptance and handling conditions based on the declaration contents. Inaccurate declarations may lead not only to accidents during transport but also to refusal of receipt, cargo loading restrictions, repackaging, relabeling, additional costs, and liability disputes among involved parties.
A critical point to note is that the Dangerous Goods Declaration must state the proper shipping name as specified in transport regulations rather than a general product name. The product name on the invoice, sales name, or commercial product name may differ from the proper shipping name shown on the declaration.
Differences Between Maritime and Air Transport
Dangerous goods declarations differ between maritime and air transport in terms of applicable regulations, format, submission destinations, deadlines, and quantity limits. Documents used for maritime transport cannot necessarily be used as-is for air transport.
| Category | Maritime Transport | Air Transport | Practical Notes |
|---|---|---|---|
| Main Regulations | Primarily refer to the IMDG Code. | Primarily refer to the IATA Dangerous Goods Regulations. | Even for the same hazardous materials, packaging, quantity limits, and acceptance conditions may differ between sea and air transport. |
| Examples of Document Names | Dangerous Goods Declaration, Dangerous Goods Detail Statement, Multimodal Dangerous Goods Form, etc. | Shipper’s Declaration for Dangerous Goods. | Maritime declaration forms cannot necessarily be used in the same format for air transport. |
| Main Submission Destinations | Shipping lines, NVOCCs, CFS, hazardous materials warehouses. | Airlines, air freight forwarders, courier companies, air cargo terminals. | Submission deadlines, completion details, and required attachments may vary by recipient. |
| Frequently Checked Items | UN number, hazard class, packaging group, marine pollutant status, stowage, segregation, container loading condition. | UN number, hazard class, packaging group, packing instructions, quantity limitations, passenger aircraft carriage permission, cargo aircraft-only restrictions. | Quantity limits and packaging requirements are particularly strict in air transport. |
| Consequences of Deficiencies | CFS cargo acceptance may be suspended, shipping line approval delayed, shipment postponed, cargo held at hazardous materials warehouse. | Cargo may be refused boarding, rejected at cargo terminal, flight changes, repacking, or relabeling required. | Even urgent cargo cannot proceed without confirmed hazardous materials information. |
| Practical Notes | For LCL, acceptance eligibility, compatibility with other cargo, and CFS acceptance conditions are common issues. | Even small quantities may be rejected due to airline differences or courier-specific restrictions. | When switching from maritime to air transport, the dangerous goods declaration and all details should be reconfirmed. |
Freight forwarders must avoid confusing maritime and air dangerous goods declarations. In particular, cargo accepted for sea transport may be rejected for air transport due to quantity limits or packaging requirements.
Main Entry Items and Their Verification Purpose
The Dangerous Goods Declaration contains a wide range of information, each carrying practical significance. It is necessary not only to check if fields are filled but also to understand the purpose of the information and the consequences of any deficiencies.
| Entry Item | Purpose of Verification | Impact of Deficiencies | Reference Documents / Information |
|---|---|---|---|
| Shipper and Consignee Information | Confirm who is making the declaration and to whom the cargo will be delivered. | Unclear responsibility or contact details may halt acceptance confirmation. | Invoice, B/L or AWB details, booking information |
| UN Number | Identify the hazardous material internationally. | Without this, the carrier or airline cannot determine acceptance, delaying booking. | SDS Section 14, hazardous materials assessment data, manufacturer confirmation |
| Proper Shipping Name | Identify the hazardous material using the correct name per transport regulations. | If only a product name is given, documents may be returned or correction requested. | SDS, UN number information, dangerous goods list, manufacturer confirmation |
| Hazard Class | Indicate the type of hazard involved. | Errors can cause incorrect labeling, stowage, segregation, or air transport decisions. | SDS, DGD, hazard class data |
| Subsidiary Hazard | Confirm hazards other than the primary hazard. | Omission may lead to missing required labels or segregation requirements. | SDS, subsidiary hazard section, hazardous materials assessment |
| Packing Group | Verify the degree of hazard and appropriate packaging conditions. | Improper packaging, quantity limit violations, or rejection of acceptance may result. | SDS, packaging documents, container certificates, specialized hazardous materials responses |
| Quantity / Weight | Confirm quantity as hazardous material, net weight, gross weight, and number of packages. | If inconsistent with packing list or actual goods, in-gate confirmation may be stopped. | Packing list, invoice, booking details, actual cargo |
| Type of Container / Packaging | Verify compliance of container, outer packaging, and inner packaging with regulations. | Non-UN approved containers or packaging may require repacking. | Packaging specifications, container certificates, photos, packing contractor confirmation |
| Label and Mark Information | Ensure that markings on the outer packaging match the documentation. | Insufficient labels, missing UN number, or missing orientation marks may cause refusal of acceptance. | Photos of packaging, actual labels, CFS or warehouse acceptance conditions |
| Marine Pollutant Designation | Confirm if environmental regulations require special marking or declaration for sea transport. | Omission can lead to shipper approval issues or problems at CFS in-gate. | SDS, environmental information, marine pollutant marking, carrier confirmation |
| Emergency Contact | Secure valid contact details for emergency response. | Delayed emergency response and possible document return by the accepting party. | Shipper response, manufacturer contact, emergency response desk |
| Signature and Date | Clarify who verified the declaration content and the declaration date. | Unsigned or undated declarations may be rejected as official documents. | Declarer information, submission date, format requirements |
Relation with SDS
The SDS is a critical document for preparing and verifying the hazardous materials declaration. The transport information section of the SDS may include details such as the UN number, proper shipping name, hazard class, packing group, and marine pollutant status.
However, the information in the SDS and the hazardous materials declaration does not always match. Situations may arise where the SDS is outdated, the product name differs, concentration levels have changed, transport modes vary, or conditions differ between maritime and air transport.
Freight forwarders must cross-check the hazardous materials declaration against the SDS transport information upon receipt. Particular attention should be paid to discrepancies in the UN number, proper shipping name, hazard class, packing group, subsidiary hazards, and marine pollutant designation, as these are common points of inconsistency between the SDS and the declaration.
Responsibility for Preparation and Scope of Freight Forwarder Review
The Dangerous Goods Declaration is a document for accurately reporting hazardous cargo information and is closely linked to the shipper’s responsibility. It is important that the freight forwarder not only forwards the document but also checks for obvious discrepancies or omissions. However, freight forwarders should be cautious about independently determining the cargo classification themselves.
| Stakeholder | Main Role | Practical Considerations | Actions When Issues Arise |
|---|---|---|---|
| Shipper / Cargo Owner | Declare hazardous cargo information and verify consistency between actual cargo, SDS, packaging, and labeling. | They bear ultimate responsibility for the declaration contents, so the basis for classification should be confirmed. | Prepare SDS, confirm with manufacturer, and arrange hazardous cargo classification documents. |
| Manufacturer | Provide SDS, composition data, classification basis, and transport information. | If product specifications or concentrations change, the latest SDS or manufacturer confirmation letter may be required. | Request verification of the latest documents, product specifications, and transport information. |
| Hazardous Materials Specialist | Support classification confirmation, preparation of the Dangerous Goods Declaration, packing, labeling, and marking. | Act as practical consultants if the shipper cannot prepare the declaration or if classification judgment is difficult. | Request assistance with classification basis, packaging, labeling, and document preparation. |
| Freight Forwarder | Verify documentation, confirm acceptance, and coordinate with shipping lines, airlines, and warehouses. | Check for clear inconsistencies among SDS, declaration, invoice, packing list, and actual cargo information, and return to shipper if there are doubts. | Avoid speculative classification; confirm with shipper, manufacturer, or specialist. |
If the freight forwarder is asked to prepare the Dangerous Goods Declaration on behalf of the shipper, they must have a clear instruction from the shipper, the latest SDS, actual cargo information, packaging details, quantity data, manufacturer confirmation, and an established internal hazardous materials handling system. The freight forwarder should avoid entering UN numbers or packaging group designations based on guesswork without a clear classification basis.
Criteria for Freight Forwarders Acting on Behalf of Shippers
Even if the shipper cannot prepare the dangerous goods declaration, freight forwarders cannot always act on their behalf. The decision to do so depends on the reliability of the information and the availability of specialized expertise.
| Situation | Approach to Acting on Behalf | Practical Measures | Notes |
|---|---|---|---|
| Latest SDS is available, and UN number, proper shipping name, class, and packaging group are clearly identified | If the company has internal systems, qualified personnel, or specialists, acting on behalf can be considered. | Prepare the declaration based on the SDS and actual cargo information after obtaining shipper confirmation. | Keep records of the preparer, reviewer, and shipper approval. |
| SDS is available, but the transport information section is blank or unclear | Do not make judgments based on the freight forwarder’s assessment alone. | Request confirmation from the manufacturer or hazardous materials specialist and ask for SDS correction. | Do not speculate UN numbers or packaging groups. |
| Only product name, catalog, or invoice are provided | Should not act on behalf under these conditions. | Request submission of SDS, ingredient information, or manufacturer confirmation letter. | Dangerous goods classification cannot be determined from product name alone. |
| Contents of SDS and declaration differ | Do not submit as is. | Return to the shipper and clarify which information is correct through manufacturer confirmation. | Submitting inconsistent information could lead to refusal of carriage or liability issues in case of incidents. |
| If quantity restrictions or packaging standards apply for air transport | Exercise particular caution in judgment. | Check IATA regulations, airline-specific differences, packaging standards, and conditions for passenger and cargo aircraft. | Avoid reusing maritime transport information; reconfirm specifically for air transport. |
| Cargo requiring confirmation by hazardous materials specialists | It is safer not to act solely on behalf as a freight forwarder. | Request classification confirmation from hazardous materials specialists, manufacturers, or shippers. | Delay creating or submitting the declaration until classification basis is clearly identified. |
Creating a dangerous goods declaration on behalf of the shipper is not merely a clerical task. Without a proper understanding of classification, packaging, labeling, quantity limits, and transport conditions, accidents or transport suspension could result. When in doubt, confirming with the shipper, manufacturer, or hazardous materials specialists is the safest course of action.
Verification Sequence When Documents and Physical Cargo Do Not Match
Discrepancies may occur between the SDS, invoice, packing list, actual cargo labels, outer packaging markings, and booking information on the dangerous goods declaration. In such cases, do not rely on just one document. Instead, verify by referring back to the actual cargo and the latest classification basis.
| Example of Discrepancy | Verification Approach | Recommended Action | Parties or Documents to Confirm |
|---|---|---|---|
| UN number differs between SDS and dangerous goods declaration | Do not guess or select one arbitrarily. | Confirm with the shipper or manufacturer and correct the SDS or declaration based on the accurate classification. | Shipper, Manufacturer, Latest SDS, Hazardous Materials Classification Reference |
| Invoice item name differs from official transport name | Product names and official transport names may not always match. | Cross-check the official transport name against the SDS for regulatory compliance. | SDS, Dangerous Goods Declaration, Invoice, Manufacturer Confirmation |
| Quantity on packing list differs from declaration quantity | Verify against the actual cargo’s quantity and number of packages. | Reconcile the packing list, declaration, and booking details. | Shipper, Packer, Warehouse, Packing List, Actual Cargo Information |
| Class on outer packaging label differs from declaration | Treat as a serious mismatch. | Check with the shipper before in-gate; if necessary, relabel or amend the declaration. | Photos of Actual Cargo, Outer Packaging Labels, SDS, Dangerous Goods Declaration |
| Information intended for maritime transport is used for air transport | Transport mode changes conditions significantly. | Confirm air transport packaging standards, quantity limits, and airline requirements. | IATA Regulations, Airline, Air Freight Agent, SDS |
| Cargo has hazardous materials labels but shipper declares as non-hazardous | Do not treat as non-hazardous until verification is complete. | Request supporting evidence such as SDS, manufacturer confirmation, or a non-hazardous certification. | Shipper, Manufacturer, Photos of Actual Cargo, Non-Hazardous Certification |
In practice, the basic principle is never to submit with unresolved discrepancies. Simply amending the dangerous goods declaration without aligning the SDS, cargo labels, packaging, and booking information could lead to delays or rejection during in-gate or prior to loading.
Points to Note in Maritime Transport
In maritime transport, the hazardous material declaration is reviewed based on the IMDG Code. Shipping lines determine acceptance eligibility by checking the UN number, hazard class, packaging group, quantity, cargo form, marine pollutant status, stowage, and segregation requirements.
For LCL consolidations, acceptance at the CFS and compatibility with other cargo are also critical. Incomplete or insufficient hazardous material declarations can lead to delays or refusals at CFS in-gate, prohibition of consolidation, or delayed shipping line approval.
Even with FCL shipments, failure to provide a proper hazardous material declaration, container packing certificate, labels, placards, or appropriate container stowage can result in halted in-gate or loading processes. Early verification is especially important for marine pollutants, segregation requirements, temperature control, and cargo with leakage risk.
Points of Caution in Air Transport
In air transport, a Shipper’s Declaration for Dangerous Goods may be required in accordance with IATA Dangerous Goods Regulations. Air transport of hazardous materials involves strict checks on packaging standards, quantity limits, labels, markings, whether the goods can be carried on passenger aircraft, and conditions for cargo-only aircraft.
It is important to note that documentation deficiencies in air transport are more likely to result in cargo being refused for loading compared to maritime transport. Particular attention should be paid to items such as lithium batteries, aerosols, paints, adhesives, fragrances, alcohol-containing products, and reagents, as airlines and courier companies may impose additional restrictions.
Furthermore, air transport requires careful attention not only to the dangerous goods declaration but also to detailed requirements such as packaging standards, quantity per package, overpack markings, orientation arrows, and exclusive cargo aircraft labels. Even for urgent shipments, if hazardous materials information is not finalized, it may not be possible to secure a booking on the desired flight in advance.
Comparison Table of Freight Forwarder Involvement
| Category | Supportable Actions | Actions to Avoid Definitive Judgment | Practical Response |
|---|---|---|---|
| Receipt of Dangerous Goods Declaration | Confirm whether the declaration has been submitted and if all required items are filled out. | Assuming the contents are correct just because the declaration exists. | Cross-check against SDS, invoice, packing list, and actual cargo markings. |
| Verification Against SDS | Match the UN number, proper shipping name, class, packaging group, and subsidiary hazards. | Submitting the declaration with discrepancies between SDS and declaration unchecked. | If inconsistencies exist, confirm with the shipper or manufacturer. |
| Maritime Transport Confirmation | Check DGD, detailed dangerous goods list, marine pollutants, CFS in-gate, and shipping line approvals. | Assuming maritime information can be applied to air transport as well. | Verify formats and conditions for each mode of transport. |
| Air Transport Confirmation | Confirm Shipper’s Declaration, packaging standards, quantity limits, and airline-specific conditions. | Assuming acceptance for maritime transport guarantees acceptance for air transport. | Confirm IATA requirements and variations between airlines. |
| Declaration Preparation Support | If documentation is clear and internal processes are established, assist with preparation after obtaining shipper confirmation. | Guessing and entering UN numbers or packaging groups without clear classification basis. | Obtain confirmation from the shipper, manufacturer, or dangerous goods specialist. |
| Physical and Label Verification | Verify that outer labels, UN number markings, quantity, and packaging correspond to the declaration details. | Relying solely on documentation without confirming actual cargo markings. | Cross-check via photos or warehouse inspections before in-gate. |
| Acceptance Confirmation | Communicate dangerous goods information to the shipping line, airline, CFS, warehouse, and delivery companies for confirmation. | Assuming all parties will accept the cargo if regulations permit. | Record each party’s response and conditions. |
| If Doubts Remain | Withhold submission, in-gate, and loading until classification basis is properly reconfirmed. | Submitting declarations with discrepancies due to deadline pressure. | Return to the shipper, obtain corrected documents, and resubmit. |
Common Practical Issues
| Issue | Problem Points | Documents/Parties to Check | Recommended Actions |
|---|---|---|---|
| Mismatch between SDS and Dangerous Goods Declaration UN numbers | The correct classification cannot be confirmed due to an outdated SDS, use of SDS for a different product, or transcription errors. | SDS, DGD, shipper, manufacturer, hazardous materials assessment documents | Confirm with the shipper or manufacturer, then correct the SDS or declaration accordingly. |
| Product name is used instead of the official shipping name | The invoice name is recorded as is, not the proper shipping name required under transport regulations. | Section 14 of SDS, UN number information, invoice, manufacturer confirmation | Correct to the official shipping name and ensure consistency across documents. |
| Packaging group or subsidiary hazards are omitted | Insufficient SDS review or incomplete understanding of hazardous material classification leads to missing packaging or label requirements. | SDS, hazardous materials assessment documents, DGD, manufacturer responses | Add the missing information and verify any additional labeling or segregation requirements. |
| Quantities or package counts do not match the packing list | Changes in shipment quantity, packaging, or failure to update the declaration cause inconsistencies with the actual cargo. | Packing list, invoice, DGD, warehouse records, photos of actual cargo | Reconcile actual cargo, packing list, declaration, and booking details. |
| Marine pollutant declaration is missing | Environmental or transport information on the SDS is overlooked, resulting in inadequate markings and declaration for sea transport. | SDS, marine pollutant applicability, shipping line feedback, outer packaging markings | Recheck the SDS, and if applicable, correct the declaration and outer package labels. |
| Mismatch between outer packaging labels and documentation | Old labels remain, labels are applied incorrectly, or transcription errors cause discrepancies between the physical cargo and declared information. | Photos of packaging, DGD, SDS, warehouse verification, CFS requirements | Physically inspect the cargo and relabel or revise the declaration as needed. |
| Dangerous goods declaration does not comply with IATA requirements for air transport | Sea transport information is reused without checking packaging standards or quantity limitations for air transport. | IATA regulations, airline feedback, packaging documents, SDS | Review air transport requirements specifically and revise the declaration if necessary. |
| Missing signature, date, or emergency contact information | Insufficient format checks or reuse of templates results in incomplete official documentation. | DGD, Shipper’s Declaration, shipper feedback, emergency contact details | Confirm all mandatory fields before submission and include valid emergency contacts and signature dates. |
4-Column Checklist
| Verification Scenario | Party to Confirm With | Items to Confirm | Actions if Issues Are Found |
|---|---|---|---|
| Upon Receiving the Dangerous Goods Declaration | Shipper / Dangerous Goods Declarant | Verify UN number, proper shipping name, hazard class, packaging group, quantity, packaging, signature, and date. | If any details are missing, request corrections before submission. |
| When Comparing with the SDS | Shipper / Manufacturer | Confirm that Section 14 of the SDS matches the declaration’s UN number, proper shipping name, class, packaging group, and subsidiary hazards. | If discrepancies exist, seek confirmation from the manufacturer or request corrected documents. |
| When Submitting for Maritime Transport | Shipping Line / NVOCC / CFS | Check Dangerous Goods Declaration (DGD), marine pollutant status, CFS intake conditions, LCL consolidation eligibility, and need for container loading certification. | If acceptance is denied or documentation is incomplete, consider alternative shipping line, different CFS, converting to FCL, or resubmitting corrected documents. |
| When Submitting for Air Transport | Airline / Air Freight Agent / Courier | Verify Shipper’s Declaration, packaging standards, quantity limits, passenger aircraft carriage eligibility, and cargo-only aircraft conditions. | If conditions are not met, consider repackaging, changing flights, using another airline, or switching to maritime transport. |
| When Checking Quantity and Packaging | Shipper / Packer / Warehouse | Confirm that the DGD, packing list, invoice, and actual cargo quantities, packaging numbers, containers, and weights match. | If inconsistencies exist, correct the packing list or declaration before intake. |
| When Inspecting External Markings | Shipper / Warehouse / CFS / Air Freight Warehouse | Confirm that dangerous goods labels, UN number markings, marine pollutant marks, and orientation arrows match the declaration details. | If defects are found, perform relabeling, repackaging, or correct the markings. |
| When a Freight Forwarder Is Considering Preparation on Behalf of the Shipper | Shipper / Manufacturer / Dangerous Goods Specialist | Verify the latest SDS, actual cargo information, packaging details, quantity data, classification basis, and shipper approval. | If the rationale is unclear, refrain from preparing the declaration and seek specialist verification. |
| If There Is Suspicion of Non-Declaration or Incorrect Declaration | Shipper / Manufacturer / Warehouse / CFS / Shipping Line / Airline | Confirm with the actual cargo, SDS, DGD, external labels, booking information, and acceptance conditions. | Do not continue processing as regular cargo; stop operations and reconfirm. |
Example 1: Case Where the UN Number on the SDS and DGD Did Not Match
The shipper submitted both the SDS and the DGD, but the UN number in Section 14 of the SDS did not match the UN number on the DGD.
In this situation, do not guess or select either number to submit to the shipping line or airline. It could be due to an outdated SDS, an SDS for a different product, transcription errors, or classification changes.
The freight forwarder should verify with the shipper or manufacturer to confirm the specific product, the latest SDS, the correct UN number, the official proper shipping name, the hazard class, and the packaging group.
Then cross-check the DGD, invoice, packing list, outer packaging labels, and booking information, and only submit after these discrepancies have been resolved.
Example 2: Attempted Use of a Maritime DGD for Air Transport
Due to shipment delays, the shipper requested to switch hazardous cargo to air transport, and attempted to submit the Dangerous Goods Declaration (DGD) prepared for maritime transport directly to the airline.
Maritime and air transport have different applicable regulations, formats, packaging standards, quantity limits, passenger aircraft carriage eligibility, and conditions exclusive to freighter aircraft. Information intended for maritime use cannot necessarily be used as is for air transport.
The freight forwarder should verify compliance with the IATA Dangerous Goods Regulations, airline-specific conditions, packaging, quantity restrictions, and whether a Shipper’s Declaration for Dangerous Goods is required.
If the cargo does not meet air transport requirements, options include repackaging, redrafting documents, changing flights, using freighter services, selecting a different airline, or continuing maritime transport.
Example 3: Case Where Outer Packaging Label and Dangerous Goods Declaration Class Differed
In this case, the DGD indicated Class 3, while the actual outer packaging bore a Class 8 label.
Such discrepancies may not be simple labeling errors but could indicate product mix-up, leftover old labels, mistakes in preparing the declaration, or inconsistencies with the SDS.
Before proceeding with in-gate confirmation, the freight forwarder should verify with the shipper, warehouse, and manufacturer, cross-checking the SDS, DGD, invoice, packing list, and photos of the packaging.
Until the correct classification is confirmed, submission to the CFS, air cargo terminal, shipping line, or airline should be withheld.
Example 4: Case Where a Freight Forwarder Was Asked to Prepare a Declaration Based Only on the Product Name
This case involved a situation where the shipper requested, "Because it is urgent, please prepare the hazardous materials declaration using the invoice product name and catalog."
The hazardous materials declaration cannot be prepared based solely on the product name or catalog. It requires verification of the UN number, proper shipping name, hazard class, packing group, packaging, quantity, label, transport mode conditions, and other supporting details.
The freight forwarder requests the latest SDS, manufacturer confirmation, actual cargo details, packaging information, and quantity data. If the information is incomplete, the declaration should not be prepared based on assumptions.
As needed, confirmation with hazardous materials specialists or requesting the shipper to prepare the declaration may be necessary.
Points to Confirm with the Shipper
If there are unclear points in the hazardous materials declaration, the freight forwarder should promptly confirm them with the shipper. The following items especially need to be clarified before booking or cargo in-gate:
- Who will prepare the hazardous materials declaration.
- Whether it is based on the latest SDS.
- Whether the UN number, proper shipping name, class, and packaging group have been finalized.
- That maritime and air transport declarations have not been confused.
- Whether quantity, packaging form, and packaging specifications match the actual cargo.
- Whether outer packaging labels and marks are consistent with the declared information.
- If the cargo is declared non-hazardous, whether supporting documentation is available.
- Whether emergency contact information is valid.
- Whether confirmation from the manufacturer or hazardous materials specialists is required.
- If the freight forwarder is preparing the declaration on behalf of the shipper, that the shipper’s confirmation and approval have been obtained.
If the shipper cannot prepare the hazardous materials declaration, the freight forwarder should carefully consider whether they can prepare it on the shipper’s behalf. Since classification and declaration of hazardous materials relate to shipper responsibility, relying on hazardous materials specialists or manufacturer confirmation is advisable for safety.
Common Misunderstandings
It is common to mistakenly assume that simply having the dangerous goods declaration document is sufficient. For hazardous cargo transport, it is important to verify the declaration form, SDS, the actual cargo, packaging, labels, and transport mode as a complete set.
| Misunderstanding | Practical Consideration | What Should Be Checked |
|---|---|---|
| Having an SDS means the dangerous goods declaration is not required | The SDS serves as a reference for classification and has a different role from the dangerous goods declaration. | Confirm whether a declaration is required for hazardous cargo transport based on carrier conditions. |
| If the dangerous goods declaration is available, no physical inspection is needed | It is necessary to verify consistency between the declaration, external labels, packaging, quantity, and cargo condition. | Cross-check DGD, SDS, packing list, exterior photos, and warehouse inspection. |
| It is sufficient to copy the invoice product name as is | The official transport name as required by transport regulations must be confirmed for the declaration. | Verify section 14 of the SDS, UN number, and the official shipping name. |
| The declaration for maritime transport can also be used for air transport | For air transport, IATA requirements, packaging standards, quantity limits, and airline-specific conditions must be separately confirmed. | Check the Shipper’s Declaration, airline requirements, and packaging and quantity limitations. |
| Small quantities can be exempted from declaration | Limited and excepted quantity provisions have specific applicability, labeling, documentation, and acceptance conditions. | Confirm Limited Quantity, Excepted Quantity provisions, and carrier conditions. |
| The freight forwarder can decide the UN number | Classification should be based on shipper or manufacturer data, SDS, and hazardous materials regulations. | Do not guess classification; verify with the shipper, manufacturer, or hazardous materials experts. |
| Signatures and dates are formalities and can be added later | Unsigned or undated documents may not be accepted as official paperwork. | Confirm the signer, date, and format requirements before submission. |
| If the shipping line accepts it, CFS and warehouse will accept it too | Acceptance decisions by shipping lines, CFS, warehouses, and inland delivery companies are separate. | Check CFS in-gate conditions, hazardous materials warehouse criteria, and inland delivery acceptance conditions. |
Practical Points to Note
- The dangerous goods declaration must always be cross-checked against the SDS.
- Verify the UN number, proper shipping name, class, and packaging group together as a set.
- Do not confuse declarations for maritime transport with those for air transport.
- Confirm quantities, packaging, and outer markings against the actual cargo.
- Check acceptance conditions of shipping lines, airlines, and warehouses in advance.
- If there are any doubts, verify with the shipper, manufacturer, or hazardous materials specialists.
- If documents conflict, do not submit as-is; revert to the correct classification basis and verify.
- If the freight forwarder prepares the declaration on behalf of the shipper, clarify shipper confirmation and internal procedures.
- Even when submission, in-gate, or loading is urgent, do not proceed without confirming hazardous materials information definitively.
Summary
The hazardous materials declaration form is a critical document that affects both the safety of hazardous cargo transport and the acceptance decision. Accurately declaring the UN number, proper shipping name, hazard class, packaging group, quantity, packing, labels, and emergency contact details allows shipping lines, airlines, warehouses, CFS, and trucking companies to determine whether they can safely handle the cargo.
Maritime and air transport use different rules, forms, verification items, quantity limits, and submission destinations. Using maritime information for air transport or relying solely on the SDS as a substitute for the hazardous materials declaration form may lead to rejection of acceptance or transport delays.
Freight forwarders should not only forward the hazardous materials declaration form but also verify it against the SDS, actual cargo, packing, mode of transport, and the conditions of shipping lines and airlines. If there are obvious inconsistencies or missing information, it is essential to confirm with the shipper, manufacturer, or hazardous materials specialists.
The key point of this article is to treat the hazardous materials declaration form not simply as a submission document, but as a central reference linking hazardous cargo information, document consistency, physical markings, acceptance eligibility, and emergency response.
