What Documents Do Chemical and Dangerous Goods Exports Need? UN, SDS and Classification

Establish the product identity before deciding whether it is dangerous

Begin the file with the product name in Chinese and English, model or specification, use, composition information, physical form, packaging and actual shipping quantity. For mixtures, solutions, coatings, resins, powders or equipment containing batteries, make sure the description identifies the exact product being delivered rather than an unclear internal abbreviation. A different concentration, formulation or battery configuration can change the assessment, so documents should not simply be borrowed from another product.

The word “chemical” in a product description does not automatically make it dangerous goods, and the absence of a strong odour or obvious corrosivity does not establish general-cargo status. Transport classification must be based on actual composition, physical and chemical properties and applicable rules. BLUESea can assess transport characteristics from the SDS and classification documents and consider FCL, LCL or air options for non-dangerous chemicals and dangerous chemicals eligible for carriage.

Check the UN number, shipping name, class and packing group

For a substance or article classified as dangerous goods, the file commonly needs the UN number, proper shipping name, primary and subsidiary hazard classes where applicable, packing group and relevant special provisions. Packing groups I, II and III indicate degrees of danger for entries to which a packing group applies. They should not be estimated by commercial staff for booking convenience. The cargo description, SDS, classification documents and packing information must remain consistent.

Some products do not have a UN number or packing group. Certain entries may also have limited quantity, excepted quantity or other special arrangements, but applicability depends on current regulations, the product classification and carrier conditions. Never borrow the UN number of a similar product to simplify handling, and do not confuse packing group with the strength grade of the packaging material. These are different compliance concepts.

• UN number and proper shipping name, where applicable
• Primary and subsidiary hazard classes and special provisions, where applicable
• Packing group I, II or III only for entries to which it applies
• Chinese and English names, model references and consistency across documents

Provide an accurate SDS that matches the actual cargo

A Safety Data Sheet (SDS) provides information on composition, hazards, handling and storage, spills, firefighting and transport. It is an important basis for chemical assessment. The manufacturer, supplier or other responsible party with knowledge of the product should provide an accurate version. Check product and model names, formulation correspondence and preparation details. Blurred screenshots, missing pages or an SDS that does not match the physical cargo undermine later classification and carrier review.

Transport information in an SDS is an important reference, but it does not alone prove that a shipment meets every ocean, air, customs or destination requirement. A carrier may request transport classification evidence, packing documents, declarations or product photographs. If the SDS conflicts with actual composition, the UN number or another document, the responsible party should investigate and correct it. Selecting whichever version appears easier to book is not a valid solution.

Supply transport classification and packing evidence as required

A carrier or relevant regulatory process may require a transport-condition appraisal, classification report or other evidence issued by an appropriate body. Document names and requirements vary with the product, transport mode and origin. The tested sample, report product name and cargo to be shipped should correspond, and the report’s scope and validity conditions should be checked. Non-dangerous chemicals may also need evidence supporting their status, but this does not mean every general chemical shipment uses one fixed certificate.

Packing information normally covers inner and outer packaging types, materials, package counts, unit net and gross weights, total gross weight and volume, together with required packaging performance or compliance evidence, photographs, marks and labels. Dangerous goods packaging must correspond to the classification, packing group and applicable packing instructions. Replacing drums, bags, cartons or a combination packaging arrangement before shipment can change the assessment and should trigger an update rather than silent reuse of the original approval basis.

• Transport-condition appraisal or classification documents where required
• Packaging types, materials, quantities, net and gross weights and volume
• Required packaging compliance evidence, photographs, marks and labels
• Consistency among samples, reports, packaging and the actual shipment

UN38.3 applies only to specific battery transport situations

UN38.3 concerns tests in the UN Manual of Tests and Criteria and is generally relevant to certain lithium metal or lithium-ion cells and batteries, including batteries contained in equipment or packed with equipment. Where applicable, the file may need a UN38.3 test summary corresponding to the battery model and other information requested by the carrier. The test summary should have a clear relationship to the actual cell, battery or equipment configuration.

It is not a universal certificate for every chemical, electronic product or item marketed as “new energy”, and it does not replace the SDS, UN classification, packaging or other applicable documents. A chemical without batteries may have no UN38.3 requirement at all. A battery shipment may also need assessment of state of charge, packaging, protection, marks and other conditions under current ocean or air rules. Applicability always depends on the actual product, current rules and carrier review.

A complete file does not create automatic carrier approval

Ocean dangerous goods need to be assessed under the applicable IMDG Code, while air shipments involve applicable IATA DGR and carrier variations. Chinese export, port, customs, destination-country and local-agent procedures may also apply. Regulations and airline or shipping-line policies can change, so confirm the file for the current booking and shipment rather than treating an old checklist as permanent. A forwarder can review consistency, but testing, classification and truthful declaration remain tasks for the relevant responsible parties.

BLUESea can use the UN number, hazard class, packing group, SDS and transport classification documents to assist with transport feasibility, document review, dangerous goods booking, packaging confirmation, carrier approval processes and related declaration coordination. Submission does not mean every product can be carried, nor does it guarantee approval, space or a departure date. Final arrangements must comply with current applicable regulations and receive all required carrier approvals.

Use a controlled pre-booking file to reduce rework

Keep product information, SDS, classification evidence, UN details, packing descriptions, package weights and dimensions, photographs and transport requirements in one version-controlled file. Nominate a contact who can answer formulation, packaging and labelling questions. Notify the forwarder of any post-booking change to product model, quantity, packaging or transport mode so the assessment can be reconfirmed. Allowing time for additional documents and carrier review is more manageable than changing a product name or classification near the cut-off.

For an initial enquiry to BLUESea, provide the Chinese and English product names, UN number, hazard class, packing group, SDS, classification documents, packing method, package count, gross weight, volume, origin, destination and intended shipping date. Mark non-applicable or unresolved fields for confirmation rather than guessing. The team can identify missing information and approval dependencies before discussing a feasible transport arrangement.

• One clearly versioned file that matches the physical shipment
• Prompt updates for every product, packaging and transport change
• Reasonable time for carrier review and supplementary documents
• No concealment of hazards or borrowed documents in place of classification
