From Xiamen to Port Sulphur, 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 Port Sulphur.

US entry is decided as much by paperwork filed in China as by anything at the port. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.

Route profile

How Xiamen → Port Sulphur differs from other lanes

Origin port

Xiamen (Haicang / Songyu)

Fujian's battery gateway, handling more than 90% of the province's lithium battery exports, with 10-minute online packaging appraisal for compliant products and the Taiwan Strait's winter monsoon on the doorstep.

Import country

United States

Section 301 duty on Chinese lithium-ion batteries at 25% since January 2026, UFLPA scrutiny of lithium supply chains, ISF 24 hours before loading, and a US-only marking rule for SP188 packages.

Where this route gets difficult

What to watch between Xiamen and Port Sulphur: 5 points

In the order the cargo meets them: at the loading port, at sea, at Port Sulphur and at customs in United States.

  1. Origin port

    Xiamen's 10-minute packaging appraisal only works for clean data

    Xiamen Customs now issues the packaging use-appraisal certificate for lithium batteries through the single window after automatic pre-review matching: about 10 minutes in the case reported in August 2026, against roughly half a day for the old on-site inspection. The fast path is only for products that pass pre-review as compliant and valid; anything that does not match goes back 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.

  2. Sea corridor

    Gatun Lake sets the Neopanamax draft

    How deep ships can load through Panama's new locks depends on Gatun Lake. In September 2026 the Canal Authority's advisory A-33-2026 postponed a cut in the Neopanamax draft from 14.63 m to 14.48 m that had been due on 1 October, citing lake levels; a lower limit reduces what a ship bound for Port Sulphur can carry.

    What Anxin does: We check the canal advisory in force when we quote for Port Sulphur and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.

  3. Import country

    Section 301 at 25% on lithium-ion non-EV batteries from January 2026

    USTR's 2024 review moved lithium-ion batteries of HTSUS 8507.60.0020 (the 'other', non-passenger-EV line) from a 7.5% to a 25% additional duty for entries from 1 January 2026; EV traction batteries under 8507.60.0010 reached 25% in 2024. Other China-specific duties can stack on top and change with little notice, so the landed cost depends on the exact classification and entry date.

    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.

  4. 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 Port Sulphur 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.

  5. 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 Port Sulphur includes products with button or coin cells, we ask for the certificate and photos of the battery compartment warnings before booking.

Documents & compliance

Checklist for Xiamen → Port Sulphur

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.

At the Xiamen end

  • Packaging appraisal data (product, UN38.3 summary, packaging codes) checked before single-window submission
  • '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
  • 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

For the shipping line

  • Canal routing and any canal-related surcharge confirmed for the booked vessel
  • UN 38.3 test summary for every cell and battery type
  • Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)

For the importer in United States

  • HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
  • ISF filer named; stuffing location and consolidator sent right after packing
  • Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request

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.

Questions

Questions about shipping from Xiamen to Port Sulphur

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.
