From Xiamen to Brunswick, cargo moves out of Xiamen's Haicang and Songyu terminals on the Taiwan Strait, crosses a Pacific crossing and a Panama Canal transit, and is discharged at the port of Brunswick.
The US side adds a 25% Section 301 duty line, forced-labour scrutiny of lithium supply chains and an ISF deadline that falls before loading. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
- Xiamen export
- Online packaging appraisal
- Supply-chain tracing file
- HTS code 8507.60

Route profile
How Xiamen → Brunswick differs from other lanes
Asia – Americas via the Panama Canal
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
5 pain points from Xiamen to Brunswick
In the order the cargo meets them: at the loading port, at sea, at Brunswick and at customs in United States.
- Origin port
Xiamen's fast appraisal needs matching data
Through the single window, Xiamen Customs now issues the lithium battery packaging use-appraisal certificate after automatic pre-review matching: roughly 10 minutes in a case reported in August 2026, compared with about half a day for the former on-site inspection. Only products that pass pre-review as compliant and valid get the fast path; mismatches return to inspection.
What Anxin does: We check the product data, UN38.3 summary and packaging codes against the application before it is submitted, so the certificate comes through pre-review rather than falling back to an on-site check.
- Sea corridor
Hurricane season on the Caribbean side
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.
- Import country
Georgia Ports: no terminal storage for UN3536 battery systems
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.
- Import country
AMS: the manifest CBP sees before the ship leaves Xiamen
Under 19 CFR 4.7 the carrier's cargo declaration must be in CBP's Automated Manifest System 24 hours before loading abroad. Without it, or with inaccurate data, the permit to unlade the container at Brunswick can be delayed or refused.
What Anxin does: We give the carrier or NVOCC the final cargo description, HS code, UN number and package count before the documentation cut-off in Xiamen, so the AMS filing and the DG manifest say the same thing.
- Import country
Demurrage and detention invoices must follow FMC rules
Battery containers held for DG checks or paperwork can run up demurrage and detention at Brunswick. Under the FMC's billing rule, in force since May 2024, carriers and terminals must invoice within 30 days with accurate, complete information, or the charge is not payable, and the billed party has at least 30 days to ask for a waiver or refund. A 2025 court ruling set aside only the section on who may be billed.
What Anxin does: We keep the dates of discharge, availability and any DG hold for each container, so the importer can check invoices against them and dispute charges inside the FMC time limits.
Documents & compliance
What to have ready: Xiamen to Brunswick
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.
Before loading in Xiamen
- Packaging appraisal data (product, UN38.3 summary, packaging codes) checked before single-window submission
- Transport-condition classification report where applicable
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
- 'Made in China' marking on articles or containers checked on photos
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
For the carrier and the voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
- UN 38.3 test summary for every cell and battery type
For the importer in United States
- ISF filer named; stuffing location and consolidator sent right after packing
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
Before you book
One consistent file
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 Xiamen 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
What could go wrong from Xiamen to Brunswick, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Application fails pre-review and falls back to on-site inspection | Xiamen Customs | Data checked against the application first | Anxin with the manufacturer |
| Hurricane closes ports or diverts the vessel | Caribbean / Gulf, Jun–Nov | Slack in delivery plan | Carrier / consignee |
| Permit to unlade delayed for a late or inaccurate AMS manifest | Port of discharge | Final cargo data given to the carrier before the cut-off | Carrier / NVOCC, with data from Anxin |
Questions
Common questions on the Xiamen → Brunswick route
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.
For products that pass automatic pre-review, Xiamen Customs issues it through the single window; the case reported in August 2026 took about 10 minutes, against about half a day for the old on-site inspection. Products that do not pass pre-review still need inspection.
