This route runs from Fujian's battery makers through Xiamen port, then follows the Pacific, the Panama Canal and the Caribbean; at the far end is the port of Port Arthur.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. 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
- Online packaging appraisal
- Taiwan Strait monsoon Oct–Apr
- ISF filer
- Supply-chain tracing file
- HTS code 8507.60

How Xiamen → Port Arthur differs from other lanes

A duty line set by the exact 8507.60 code, lithium supply-chain questions under UFLPA, and ISF and AMS filings that are due before the box is loaded.
Where this route gets difficult
6 points to plan for on the Xiamen → Port Arthur route
Listed from loading in Xiamen to import into United States, each with what we do about it.
- Origin port
Energy-storage units may go on multipurpose ships
Xiamen's energy-storage transport guide 2.0 (August 2026) notes that some ESS containers are carried on multipurpose ships and requires a pre-voyage meeting with the terminal and lashing parties. It also lists the terminals with class 9 qualification: Xiamen Hyundai terminal, Yuanhai Tongda, and Haixiang berths 7–8.
What Anxin does: For ESS units we confirm early whether the carrier offers container-ship or multipurpose carriage, which qualified terminal is used, and who attends the pre-voyage meeting.
- Origin port
The Taiwan Strait's winter monsoon starts at the port
Ships leaving Xiamen enter the Taiwan Strait straight away. A Chinese government weather account notes that the strait's funnel effect makes winds 1–2 Beaufort levels stronger than outside it, and that the winter and spring north-east monsoon brings force 7 or stronger winds on about two-thirds of days. Container ships are advised to secure lashing.
What Anxin does: From October to April we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
- Sea corridor
Panama's draft limit depends on the lake
The Panama Canal Authority sets the maximum draft in the Neopanamax locks according to Gatun Lake levels. In September 2026 it postponed a planned cut from 14.63 m to 14.48 m that was due on 1 October (advisory A-33-2026). A lower limit means ships transiting the new locks can load less.
What Anxin does: We check the canal advisory in force when we quote for Port Arthur and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
- 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 Port Arthur. 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.
- Import country
Which 8507.60 line decides the Section 301 duty
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 Port Arthur.
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.
- 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 Port Arthur, and chase any missing invoice or HTS detail while the ship is still at sea.
Documents & compliance
Checklist for Xiamen → Port Arthur
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

- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
- 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)
Carrier and voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
For the importer in United States
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
- 24-hour emergency response number (and provider reference) for the US road leg
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Xiamen filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Port Arthur.
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 Port Arthur, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Cargo shift in winter monsoon seas | Taiwan Strait, Oct–Apr | CINS blocking and bracing checked on photos | Packing site, checked by Anxin |
| ESS unit arrives at a terminal without class 9 qualification | Xiamen port | Qualified terminal confirmed at booking | Anxin with the carrier |
| Draft cut reduces capacity or adds surcharges | Panama Canal | Advisory checked at quotation; carrier confirmation | Carrier, checked by Anxin |
Questions
Questions about shipping from Xiamen to Port Arthur
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.
