Lianyungang to Brunswick
Yellow Sea · Korea Strait · Tsugaru Strait · North Pacific · Eastern Pacific · Panama Canal · Caribbean Sea · Windward Passage
This route runs from northern Jiangsu through Lianyungang on the Yellow Sea, then follows a corridor through the Panama Canal; at the far end is the port of Brunswick.
Brunswick means US customs filings that are due while the container is still in Lianyungang, and a supply chain CBP may ask to see. Below are 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
Route profile
Jiangsu's Yellow Sea port, with a simplified document list for 'new three' cargo since 2024 and its own guide for energy-storage units on break-bulk ships.
Gatun Lake levels set how much a ship can load through Panama; the Caribbean leg then crosses hurricane waters from June to November.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Brunswick and at customs in United States.
For energy storage shipped on break-bulk vessels, Lianyungang MSA's June 2025 guide classes ESS cabinets as UN3480 and ESS containers as UN3536, recommends 20–50% remaining charge, and requires converters and monitoring switched off, series and parallel circuits disconnected, packages spread evenly with a low centre of gravity, and a safety meeting before the ship arrives.
What Anxin does: For ESS units we confirm the UN number the unit ships under, get the state of charge and isolation steps in writing from the manufacturer, and join the pre-arrival safety meeting with the stowage details.
Between April and July sea fog is a major marine hazard in the Yellow and Bohai Seas, the China Meteorological Administration says. Lianyungang, like Qingdao, can see vessels held at anchor by fog, and moving a box to another vessel means amending its DG filings.
What Anxin does: In fog season we keep slack between stuffing and the DG cut-off and have the filing data ready to amend.
After the canal, ships to Brunswick cross the Caribbean, where the Atlantic hurricane season lasts from 1 June to 30 November and peaks around 10 September; an average year brings 14 named storms and 7 hurricanes. Ports close ahead of a storm and vessels wait or divert.
What Anxin does: For August–October arrivals we build slack into delivery plans and pass the carrier's revised arrival straight to your consignee.
The IMDG waiver in 49 CFR 171.25(d)(2) spares the emergency telephone number only when cargo stays on the ship or moves between vessels without using a public highway. Once the container is trucked out of Brunswick, the shipping paper needs a numeric emergency response number that is monitored at all times and answered by someone who knows the material; an answering service that calls back does not count. Goods shipped as 'Battery powered equipment' are exempt.
What Anxin does: Before sailing we confirm who provides the 24-hour number for the US leg, usually the importer's emergency response provider, and put it with the contract reference on the DG documents we send to the trucker.
CBP must have the Importer Security Filing 24 hours before the container is laden in Lianyungang, and its liquidated damages guidelines provide for a claim for each late, inaccurate or incomplete filing. The stuffing location and consolidator can only be filled in once the container is packed, which leaves a short window.
What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Lianyungang, ahead of the vessel's loading window.
Georgia Ports Authority rules effective 1 October 2025 treat battery energy storage systems (UN3536) like explosives: at least 96 hours' written notice, no storage on any Authority facility, no receipt by rail, and at Garden City discharge or loading directly shipside. Packed cells and modules under UN3480 are not caught, so the UN number decides how the container is handled at Brunswick.
What Anxin does: We confirm the UN number with the shipper before booking. For a containerised energy storage system, we make sure the carrier gives the 96-hour notice and the consignee has trucks ready at the ship.

Documents & compliance
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Lianyungang export filings, the carrier booking and the United States import papers. We compare all three before confirming space.
Carriers we book with
Our booking panel; availability on this lane and acceptance of the declared UN numbers are confirmed for each booking. It does not mean that a listed carrier runs a direct service on this route. Carrier choice depends on the trade lane, cargo classification and each carrier's dangerous-goods acceptance at booking. The final carrier is confirmed on the booking.
Risk & mitigation
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| ESS unit not isolated or poorly distributed in a break-bulk hold | Lianyungang, break-bulk loading | Manufacturer's written isolation steps; safety meeting | Manufacturer / ship, coordinated by Anxin |
| Hurricane closes ports or diverts the vessel | Caribbean / Gulf, Jun–Nov | Slack in delivery plan | Carrier / consignee |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Yes. Under 49 CFR 171.25(b)(3), SP188 packages of UN3480 or UN3090 need the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so do packages of batteries packed with or contained in equipment above 5 kg net. We check for it on carton photos before stuffing.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
Its June 2025 break-bulk ESS guide recommends 20–50% remaining charge, with converters and monitoring off and circuits disconnected.
