From Shanghai to Freeport, cargo moves out of Shanghai, crosses a Panama Canal corridor whose draft limit depends on Gatun Lake, and is discharged at the port of Freeport.

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 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

  • Yangshan / Waigaoqiao export
  • Photo-verified packing certificate
  • ISF filer
  • Supply-chain tracing file
  • HTS code 8507.60

Where this route gets difficult

6 points to plan for on the Shanghai → Freeport route

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

  1. Origin port

    Photo evidence before Shanghai issues the packing certificate

    Shanghai's electronic packing certificate goes out by EDI only after the inspector has uploaded before, during and after stuffing photos through the MSA's remote system, with face recognition and phone location switched on. Missing, late or off-site photos, or photos that do not match the EDI cargo data, stop the container from loading. Stuffing sites outside Shanghai need registration with Shanghai MSA.

    What Anxin does: We confirm that the stuffing site (including factory sites in Jiangsu or Zhejiang) is registered for Shanghai's remote system, and we check the photo upload against the EDI data before the packing certificate is sent.

  2. Origin port

    Fire-rating proof for Shanghai stuffing warehouses

    Under Shanghai MSA's 2024 draft reporting guide, a warehouse stuffing lithium battery dangerous goods must hold fire-department proof of its fire hazard class and fire-resistance rating, and keep its details current on the Shanghai single window, which took over MSA account and site records in 2026.

    What Anxin does: We only propose stuffing sites that can show the fire-safety documents and are on Shanghai MSA's system; if you use your own warehouse, we check this before booking.

  3. 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 Freeport and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.

  4. Import country

    'China' has to be marked on each article or its container

    19 CFR 134.11 requires every imported article, or its container, to carry the English name of the country of origin in a conspicuous place, as legibly, indelibly and permanently as the article allows, at the time it is imported. Batteries and battery products reaching Freeport without it can be held until they are marked.

    What Anxin does: We check product and carton photos for a durable 'Made in China' marking before stuffing in Shanghai, rather than leaving it for re-marking in a US warehouse.

  5. Import country

    A monitored US emergency number for the truck leg

    The IMDG waiver in 49 CFR 171.25(d)(2) spares the emergency telephone number only when cargo stays on the ship or moves between vessels without using a public highway. Once the container is trucked out of Freeport, the shipping paper needs a numeric emergency response number that is monitored at all times and answered by someone who knows the material; an answering service that calls back does not count. Goods shipped as 'Battery powered equipment' are exempt.

    What Anxin does: Before sailing we confirm who provides the 24-hour number for the US leg, usually the importer's emergency response provider, and put it with the contract reference on the DG documents we send to the trucker.

  6. Import country

    The FMC's 30-day rules on demurrage and detention bills

    If a battery container waits at Freeport, 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.

Documents & compliance

What to have ready: Shanghai to Freeport

Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

In Shanghai, before the box is loaded

  • Stuffing photos (before, during, after) uploaded to Shanghai MSA's remote system before the EDI packing certificate is sent
  • Stuffing site registered and geo-verified with Shanghai MSA; fire-safety proof for lithium DG warehouses
  • 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)

For the shipping line

  • 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 import into United States

  • 24-hour emergency response number (and provider reference) for the US road leg
  • Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
  • CPSC certificate data and eFiling arrangement, if the product is subject to certification

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 Shanghai 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 Shanghai to Freeport

For lithium-ion batteries classified in HTSUS 8507.60.0020 and entered from 1 January 2026, USTR set the Section 301 additional duty at 25%; EV traction batteries in 8507.60.0010 have been at 25% since 2024. Other duties can apply on top. The importer's customs broker confirms the classification and total duty; we make sure the invoice gives the broker enough detail to do so.

1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.

It can, but Shanghai MSA checks the phone location of the packing photos against a verified stuffing site, and sites outside Shanghai must be registered with it. We confirm registration before the stuffing date; otherwise the container can be refused for loading.
