Lithium batteries for Miami go through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules. On the way they face a corridor through the Panama Canal, and they arrive at the port of Miami.

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 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.

What we need to start

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

Route profile

What sets Shanghai → Miami apart

Origin port

Shanghai (Yangshan / Waigaoqiao)

Yangshan and Waigaoqiao exports under Shanghai MSA's photo-verified packing system, where a mismatch between photos and EDI data keeps a DG box off the ship.

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 Shanghai and Miami: 5 points

Loading port first, then the sea leg, then Miami and the United States market.

  1. Origin port

    Shanghai checks during and after the voyage filing, not just before

    Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration from the stuffing company, but places the burden on the shipper: the batteries must meet the UN tests and be protected against damage, short circuit and accidental activation, and MSA runs spot checks during and after the process, with proof to be produced on request.

    What Anxin does: We keep a file per container (UN38.3 summary, SDS, packing photos, terminal protection details) so that proof can be produced the same day if Shanghai MSA asks for it after sailing.

  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 Miami can carry.

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

  3. Import country

    AMS: the manifest CBP sees before the ship leaves Shanghai

    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 Miami 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 Shanghai, so the AMS filing and the DG manifest say the same thing.

  4. Import country

    Where the lithium came from: UFLPA questions at entry

    Since August 2025 lithium has been a high-priority sector under the Uyghur Forced Labor Prevention Act, and CBP had by then stopped more than 16,700 shipments for UFLPA review. A container for Miami can be held while the importer shows where the cells, cathode material and lithium compounds were sourced.

    What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.

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

Documents & compliance

Documents to line up for Shanghai → Miami

These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

Before loading in Shanghai

  • Per-container evidence file (UN38.3 summary, SDS, photos, short-circuit protection) kept for Shanghai MSA spot checks
  • 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)
  • 'Made in China' marking on articles or containers checked on photos

For the carrier and the voyage

  • Canal routing and any canal-related surcharge confirmed for the booked vessel
  • Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
  • SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label

At the United States end

  • 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
  • 24-hour emergency response number (and provider reference) for the US road leg

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 Shanghai 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.

Questions

Common questions on the Shanghai → Miami route

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.

Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration issued by the stuffing company. Either way, the shipper remains responsible and must provide proof if MSA spot-checks.
