UN-spec packaging, DG packaging certificate (危包证), expedited in 3 working days. Performance certificates, MSDS, and safety data sheets prepared by our team.
Maritime dangerous goods declaration submitted to port authorities. We pre-book with DG-approved carriers, MSK, HPL, MSC, COSCO, HMM, OOCL, EMC, YML, for confirmed space even in peak season.
Secondary reinforcement, leak-proof treatment for fragile/liquid cargo. Professional container stuffing supervised by DG-certified personnel. Custom packaging: IBC drums, steel drums, cartons as required.
Real-time GPS tracking across all transport modes. We coordinate with specialist DG customs brokers at destination ports for seamless dual-clearance, including bonded transit and inland delivery to final door.
In summary, Great Hensen's dangerous goods freight service from China follows a structured five-step compliance process — from IMDG classification and UN-spec packaging certification to port declaration, DG-supervised container loading, and destination customs clearance — ensuring every hazardous shipment meets regulatory standards with zero incidents.
Not all ports accept all DG classes. We match your cargo to the right port, based on carrier availability, DG acceptance policy, and transit time to destination.
Our headquarters port. Best for Class 9, UN3536 energy storage, and general DG to Europe, South America, and Africa.
China's largest port. Best for chemical DG (Class 3, 6, 8) with the widest carrier choice and highest sailing frequency.
Northern China gateway. Best for DG to Russia, Central Asia, and China-Europe rail intermodal shipments.
In summary, Great Hensen leverages a three-port strategy — Qingdao for UN3536 energy storage and general DG to Europe/South America/Africa, Shanghai for chemical DG with the widest carrier choice, and Tianjin for northern China manufacturers and China-Europe rail intermodal — matching each dangerous goods shipment to the most DG-friendly departure port.
Containerized lithium-ion battery energy storage systems are the hardest DG category to ship. Most freight forwarders won't touch it. We've made it our specialty.
Serving multiple top-tier Chinese energy storage manufacturers. Cargo sourced from inland factories across China, moved via river-sea combined transport to European base ports, then trucked to inland European door points.
Serving chemical companies across Shandong and China. We handle the full compliance chain: classification identification, DG packaging certificate expedited in 3 working days, MSDS preparation, and multi-port flexible shipping via Qingdao, Shanghai, or Tianjin. Door-to-door dual clearance with specialist chemical brokers at destination.
In summary, Great Hensen has safely shipped over 1,000 TEU of UN3536 energy storage systems from China to Europe, handling inland factory pickup, river-sea combined transport, DG documentation, and door-to-door delivery — making containerized lithium battery energy storage a proven specialty rather than an experimental service.

In summary, Great Hensen combines an unblemished DG safety record, 3-day DG packaging certificate turnaround, long-term carrier agreements with eight major shipping lines, and true door-to-door DG logistics — including inland transport, dual-clearance customs brokerage, and final delivery — to provide a single point of accountability for the entire dangerous goods supply chain.
We handle IMDG Classes 2 through 9: Class 2 (Gases), Class 3 (Flammable Liquids), Class 4 (Flammable Solids), Class 5 (Oxidizing Substances), Class 6 (Toxic Substances), Class 7 (Radioactive, limited), Class 8 (Corrosives), and Class 9 (Miscellaneous DG, including UN3536 lithium battery energy storage systems). We ship via sea, air, and rail, with full IMDG/IATA DGR/RID compliance for each mode.
UN3536 covers lithium batteries installed in cargo transport units, typically large-scale containerized Battery Energy Storage Systems (BESS). Unlike UN3480 (lithium-ion batteries shipped standalone) or UN3481 (batteries packed with equipment), UN3536 covers batteries that are permanently installed in a structure (the container itself). This classification has specific documentation, packaging, and handling requirements distinct from other lithium battery categories. We have shipped 1,000+ TEU of UN3536 cargo, it is our specialty.
A standard DG export requires: (1) MSDS (Material Safety Data Sheet, per GHS standards), (2) DG Packaging Certificate (危包证, confirming packaging meets UN performance standards), (3) Maritime DG Declaration (submitted to the maritime authority 24-48 hours before loading), (4) Port Filing Approval (required by Chinese ports for DG cargo), (5) Packing List with DG classification noted, (6) Commercial Invoice, and (7) Carrier DG Booking Confirmation. We handle the entire document chain, pre-auditing every document before submission to ensure zero rejections.
Industry standard is 7-10 working days. Our accelerated process delivers in 3 working days for most DG classes. This is possible because we manage the entire chain, packaging performance testing coordination, application preparation, and authority submission, in-house, without relying on third-party agents. See our chemical DG case study for how this process works in practice. For time-critical shipments, the 3-day turnaround can be the difference between making a sailing and waiting two weeks for the next one.
We maintain DG-approved relationships with 10+ major carriers: MSK (Maersk), HPL (Hapag-Lloyd), MSC, COSCO, HMM, OOCL, EMC (Evergreen), YML (Yang Ming), and others. Each carrier has different DG acceptance policies, varying by DG class, route, and season. Our team knows which carrier accepts which DG class on which route, and books accordingly. During peak season when DG space is the first to be cut, our allocated space agreements protect our clients' shipments.
We offer three-port optionality: Qingdao (primary, strongest DG infrastructure in northern China, dedicated DG storage yards, highest sailing frequency to Asia/South America/Africa), Shanghai (best for Europe and North America routes, widest carrier choice), and Tianjin (optimal for northern China origins and Russia/Central Asia destinations). We match cargo attributes, DG class, destination, and timeline to the optimal port, not just the closest one.
Carrier DG policy changes are becoming more frequent, driven by: insurance cost escalation (a single container fire can trigger claims exceeding $100 million (read about DG risk trends)), vessel capacity optimization (non-DG cargo generates higher revenue per slot without additional risk), and specific route incidents that cause carriers to temporarily suspend DG on affected corridors. This is why we maintain relationships with 10+ carriers, when one suspends, we have immediate alternatives. We also provide early warning of pending carrier policy changes.
Our safety system operates on four pillars: (1) Pre-shipment compliance audit, every document reviewed by our in-house DG specialist before authority submission. (2) Packaging verification, we confirm that packaging matches the DG certificate specifications before cargo leaves the factory. (3) Carrier compatibility check, we verify that the specific vessel and stowage position are approved for the DG class and quantity. (4) Real-time monitoring, DG cargo milestones tracked and reported daily. Result: zero DG incidents across 1,000+ TEU shipped.
Yes. We provide door-to-door service with dual customs clearance (China export + destination import). We work with specialist DG customs brokers at destination ports in Europe, South America, the Middle East, and Africa, brokers who understand DG-specific import permit requirements, tariff classifications, and inspection procedures. The client receives their DG cargo at their warehouse, not at the port.

We handle IMDG Classes 2 through 9, including gases, flammable liquids, flammable solids, oxidizing substances, toxic substances, corrosives, and miscellaneous DG including UN3536. We ship via sea, air, and rail from Qingdao, Shanghai, and Tianjin ports.
Typically 2-3 working days for standard DG classes when the manufacturer has proper test reports. For complex classifications, allow 5 working days. Our in-house DG specialist pre-audits all documentation to catch potential rejection issues before submission.
MSK, HPL, MSC, COSCO, HMM, OOCL, EMC, YML, and CMA CGM all accept DG cargo, but each has different restrictions per class and destination. We route your shipment through the most DG-friendly carrier and port combination for your specific cargo.
Core documents: DG Packaging Certificate (危包证), Maritime DG Declaration, MSDS (Material Safety Data Sheet), IMDG compliance declaration, commercial invoice, packing list, and bill of lading. Additional documents may be required depending on the DG class and destination country.
DG sea freight typically carries a 15-40% surcharge over standard cargo, depending on the IMDG class, packing group, and carrier. This surcharge covers DG declaration fees, specialized container handling, and compliance documentation. Air freight DG surcharges are significantly higher due to stricter IATA DGR requirements and limited capacity.
Lithium batteries require UN38.3 test certification, a compliant MSDS, UN-spec packaging with short-circuit protection, and a DG Packaging Certificate. For UN3536 energy storage systems, SP389 compliance is mandatory. We pre-audit all lithium battery documentation before submission to avoid port rejection and ensure carrier acceptance.
