DG ocean freight (FCL) is a full-container-load sea shipping service booked under Class 9 dangerous goods regulations, purpose-built for charged new-energy cargo such as lithium batteries, energy storage cabinets and EV batteries. Unlike standard FCL, both the shipping line and the freight forwarder must hold dangerous-goods qualifications: DG space must be requested separately from the carrier, and cargo must be declared, labelled and segregated in line with the IMDG Code. HUIN International Logistics holds NVOCC and IMDG qualifications and has contracted DG space with six shipping lines, ensuring compliant and stable FCL bookings for charged cargo..

Cargo suitable for DG ocean FCL includes: lithium batteries (cells, modules and packs), energy storage cabinets and systems (including oversized 43/45-ton units), EV traction batteries, solar panels, new-energy vehicles, and powered equipment such as EV chargers and inverters. The prerequisites are that goods have passed testing such as UN38.3 and are accompanied by an MSDS, a dangerous-goods packaging certificate (where applicable) and a transport appraisal certificate. Different cargo types carry different UN numbers, packing groups and segregation requirements. HUIN offers a free evaluation of your cargo type and document readiness to confirm DG FCL eligibility before you book..

Four types of documents are typically required: ① a UN38.3 test report (mandatory for lithium batteries); ② an MSDS (Material Safety Data Sheet, preferably less than one year old); ③ a dangerous-goods packaging certificate for export packaging (where applicable); and ④ a maritime transport appraisal certificate. You will also need the commercial invoice, packing list and customs declaration, with the accurate UN number, packing group and piece count stated on the declaration. Documents must match the actual cargo, or carriers may refuse the booking and destination authorities may inspect. HUIN provides one-stop arrangement for UN38.3, MSDS, packaging certificates and appraisal reports, coordinating issuance with booking so incomplete paperwork never delays your sailing..

The price typically has four parts: base ocean freight, a DG surcharge, documentation/handling fees, and destination charges. DG costs more because shipping lines price DG space separately with limited allocations; certified staff must make IMDG-compliant declarations; and terminal segregation plus dangerous-goods container management add expense. Lithium battery cargo generally incurs a per-container DG surcharge whose amount varies by line, route and cargo type. HUIN holds direct DG allocations from six shipping lines and compares multiple carriers on the same route; our quotations itemize the ocean freight and every surcharge with no hidden fees.
