Lithium batteries for Brunswick go out of Qingdao on the Yellow Sea, where April to July is fog season. On the way they face a corridor through the Panama Canal, and they arrive at the port of Brunswick.
Brunswick means US customs filings that are due while the container is still in Qingdao, and a supply chain CBP may ask to see. This page sets out 6 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
Route profile
Qianwan exports from Shandong, where Qingdao MSA's one-document pilot cuts repeat filings for cargo moved between terminals by water.
A Pacific crossing, a Panama Canal transit that depends on lake levels, and a Caribbean passage in hurricane season.


Where this route gets difficult
Listed from loading in Qingdao to import into United States, each with what we do about it.
ESS units loading at Qingdao fall under a Shandong MSA waterway safe-transport guide written for lithium battery energy storage systems at the province's coastal ports, so preparation should follow that guide alongside the IMDG Code.
What Anxin does: For ESS cargo we review the unit's packing and securing plan against the Shandong guide with the packing site before booking.
The China Meteorological Administration lists sea fog among the major marine hazards of the Yellow and Bohai Seas, mostly between April and July and with a serious effect on shipping. At Qingdao a fog hold can shift a battery container onto another vessel, and its DG filings must follow.
What Anxin does: In fog season we leave slack between stuffing and the DG cut-off at Qianwan and keep the cargo report ready to amend quickly if the vessel changes.
The Atlantic hurricane season, covering the Caribbean and the Gulf of America, runs from 1 June to 30 November, peaking around 10 September, with an average of 14 named storms. Ports on the way to Brunswick close ahead of storms, and ships 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.
For lithium-ion batteries entered from 1 January 2026 USTR set the Section 301 additional duty on HTSUS 8507.60.0020 (the non-EV line) at 25%, the level EV batteries under 8507.60.0010 reached in 2024. Other China-specific duties can be added and change at short notice, so the classification and the entry date both move the landed cost at Brunswick.
What Anxin does: We do not give duty rulings. We make sure the invoice describes chemistry, configuration and application precisely enough for the importer's customs broker to classify it, and we flag the entry date when a vessel's arrival could straddle a duty change.
A container landed at Brunswick without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Brunswick, and chase any missing invoice or HTS detail while the ship is still at sea.
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
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

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 Qingdao 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 |
|---|---|---|---|
| Fog hold forces a vessel change after filing | Qingdao, Apr–Jul | Slack in schedule; amendment-ready filing | Anxin with the declarant |
| Hurricane closes ports or diverts the vessel | Caribbean / Gulf, Jun–Nov | Slack in delivery plan | Carrier / consignee |
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.
Mainly April to July, according to the China Meteorological Administration, which calls sea fog a major hazard for Yellow Sea transport.
