Sea & Air Freight · Lithium Batteries · DG Documentation & Compliance
Wingocean ships eligible dangerous goods by sea, air and selected specialized routes—handling cargo classification, packaging assessment, booking, documentation and customs coordination.
Each shipment is assessed by cargo characteristics, UN number, hazard class, packaging, destination and applicable regulations before we recommend a solution.
Different dangerous goods require different handling procedures, packaging standards and transportation documentation. Wingocean coordinates shipment assessment and logistics arrangements according to the applicable regulations and carrier requirements.
Pre-shipment assessment to identify the applicable dangerous goods transportation requirements.
Sea freight solutions for eligible dangerous goods shipments, including containerized DG cargo.
Air freight arrangements for dangerous goods accepted by airlines and permitted under applicable aviation regulations.
Specialized shipping assessment for lithium-ion and lithium-metal batteries, as well as equipment containing or packed with batteries.
Shipping requirements depend on battery chemistry, configuration, watt-hour rating or lithium content, test status, packaging and the selected transport mode.
Support with the documentation and packaging requirements involved in dangerous goods transportation.
Dangerous goods are divided into nine hazard classes under international transportation regulations. Each class has specific requirements for classification, packaging, marking, documentation and transportation. Wingocean assesses cargo requirements individually and coordinates shipping arrangements for eligible goods, subject to route availability and carrier approval.
Explosive substances and articles.
Flammable, non-flammable and toxic gases.
Flammable liquids and related products.
Flammable solids, substances liable to spontaneous combustion and substances that emit flammable gas when in contact with water.
Oxidizing agents and organic peroxides.
Toxic substances and infectious substances.
Radioactive substances and materials.
Acids, alkalis and other corrosive materials.
Other regulated dangerous substances and articles, including lithium batteries classified under applicable entries.
Not all dangerous goods can be transported on every route or by every carrier. Acceptance depends on the specific substance, UN number, packaging, transport regulations and destination restrictions.
Dangerous goods transportation requires careful assessment, accurate documentation and coordination across multiple parties. Wingocean focuses on compliance-oriented shipment handling and practical logistics solutions.

Clearly communicate restricted and prohibited cargo requirements. We do not accept shipments involving false declarations, concealed dangerous goods or non-compliant cargo.
We assess the cargo before booking to identify applicable requirements and reduce avoidable operational risks.
Provide the product name, composition, UN number (if available), SDS/MSDS, battery specifications and shipment details.
Review the cargo classification, applicable transportation regulations, packaging requirements and route restrictions.
Coordinate required packaging arrangements, labels, marks, declarations and applicable inspection or appraisal documents.
Arrange carrier acceptance, booking and the relevant dangerous goods declaration procedures.

Required documents depend on the cargo classification, packaging, transport mode and destination.
Common documents may include:
• Safety Data Sheet (SDS/MSDS), where applicable
• Dangerous goods classification and identification report, where required
• UN packaging performance test documentation, where applicable
• Export dangerous goods packaging use appraisal, where required
• Dangerous goods declaration
• Shipping documents and supporting cargo information
For applicable shipments, export dangerous goods packaging performance testing and packaging use appraisal may be required under Chinese customs procedures. Wingocean reviews the cargo details and helps identify the applicable documentation before shipment.
Lithium-ion and lithium-metal batteries are regulated as dangerous goods under applicable transportation regulations.
However, certain battery shipments may qualify for specific exceptions or reduced documentation, packaging and labeling requirements when all relevant conditions are met. For example, some shipments may qualify under applicable special provisions or packing instruction exceptions. This does not mean that all small batteries or batteries installed in equipment are automatically exempt.
We assess each shipment based on battery type, UN number, configuration, capacity, test status and transportation mode before confirming the shipping arrangement.
We can assess dangerous goods across Classes 1–9 and coordinate transportation for eligible cargo.
However, not every dangerous substance is accepted by every airline, shipping line or route. Some goods are prohibited or subject to special approval and handling requirements. Final acceptance must be confirmed based on the cargo details and carrier requirements.
We can assess eligible lithium battery shipments for both sea and air transportation.
Sea freight requirements are governed by the applicable IMDG Code, while air freight follows the applicable ICAO Technical Instructions and IATA Dangerous Goods Regulations. The permitted packing method, documentation and transport conditions vary depending on the battery type and shipment configuration.
UN38.3 refers to the lithium battery testing requirements under Section 38.3 of the UN Manual of Tests and Criteria.
Battery manufacturers and distributors should maintain the relevant test documentation and make the UN38.3 test summary available when required.
The test summary alone does not guarantee shipment acceptance. Other classification, packaging, marking, documentation and carrier requirements must also be met.
Selected dangerous goods may be eligible for door-to-door or DDP shipping arrangements, subject to the destination country's regulations, import requirements and carrier acceptance.
The agreed quotation should clearly specify customs clearance, applicable taxes and duties, and final delivery coverage.
