Lithium batteries for Key West go out of Xiamen's Haicang and Songyu terminals on the Taiwan Strait. On the way they face a Panama Canal corridor whose draft limit depends on Gatun Lake, and they arrive at the port of Key West.
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. The 6 points below are particular to this lane; each comes with what we do and the paperwork it touches.
What we need to start
- Online packaging appraisal
- Taiwan Strait monsoon Oct–Apr
- Supply-chain tracing file
- HTS code 8507.60
- ISF filer

Where this route gets difficult
What to watch between Xiamen and Key West: 6 points
In the order the cargo meets them: at the loading port, at sea, at Key West 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.
- Origin port
Strong winds in the Taiwan Strait from day one
Leaving Xiamen, ships are in the Taiwan Strait at once. A Chinese government weather account says the strait's funnel effect adds 1–2 Beaufort levels to the wind, and that the north-east monsoon of winter and spring brings force 7 or more on about two days in three. Lashing on container ships should be secured accordingly.
What Anxin does: From October to April we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
- Sea corridor
North Pacific winter storms before the canal
NOAA's Ocean Prediction Center has recorded hurricane-force North Pacific storms in every month from October to April, most often in December. The Pacific leg to Panama crosses that ocean.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing.
- Import country
The FMC's 30-day rules on demurrage and detention bills
If a battery container waits at Key West, the demurrage or detention invoice has to arrive within 30 days and carry accurate and sufficient information, or the charge is not owed (46 CFR part 541). The billed party then has at least 30 days to dispute it; in 2025 the D.C. Circuit struck down only the rule on who may be invoiced.
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.
- Import country
Day 15 at the terminal: the General Order deadline
US customs rules give an unentered container 15 calendar days at the place of unlading. After that the carrier hands it to a bonded general order warehouse, with transport and storage at the consignee's risk and expense, and for DG cargo that needs specialized storage the port director decides where it is kept (19 CFR 4.37).
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Key West, and chase any missing invoice or HTS detail while the ship is still at sea.
- Import country
Button and coin cells: Reese's Law
Consumer products containing button or coin cells manufactured or imported after 19 March 2024 must meet the UL 4200A-2023 performance and warning-label rules adopted as 16 CFR part 1263, and battery packaging labels have been mandatory since 21 September 2024. The importer also needs a certificate citing the rule.
What Anxin does: When a shipment for Key West includes products with button or coin cells, we ask for the certificate and photos of the battery compartment warnings before booking.

Before you book
Send the file once, complete
Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Xiamen filings, the carrier booking and the United States import file. We check the three against each other before the booking is confirmed.
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
Risks on this route and who deals with them
| 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 |
| Cargo shift in winter monsoon seas | Taiwan Strait, Oct–Apr | CINS blocking and bracing checked on photos | Packing site, checked by Anxin |
Questions
Common questions on the Xiamen → Key West route
No. The carrier must also send its cargo declaration through AMS 24 hours before loading, and CBP will not issue the permit to unlade without it.
It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.
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.
