Ningbo-Zhoushan (Beilun / Meishan)
Beilun and Meishan exports under Zhejiang MSA's January 2026 battery guide, which trims duplicate filings but not the carrier's own document checks.

Lithium batteries for Martha's Vineyard go through Ningbo-Zhoushan, where Zhejiang MSA's guide sets a 60% weight-balance test for battery containers. On the way they face a corridor through the Panama Canal, and they arrive at the port of Martha's Vineyard.
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.

Route profile
Beilun and Meishan exports under Zhejiang MSA's January 2026 battery guide, which trims duplicate filings but not the carrier's own document checks.
Gatun Lake levels set how much a ship can load through Panama; the Caribbean leg then crosses hurricane waters from June to November.


Where this route gets difficult
They run from the Ningbo terminal through the voyage to Martha's Vineyard and the United States import file.
Zhejiang MSA's January 2026 battery guide sets a concrete loading test: no half of the container's length may carry more than 60% of the cargo weight, and packages must be braced. On board, deck stowage should be inside fire-fighting coverage and shaded from direct sun, and under-deck stowage in holds with temperature probes.
What Anxin does: We ask for the load plan before stuffing and check the 60% split on the stuffing photos, and we pass the shading and away-from-heat stowage request to the carrier on the booking.
Zhejiang MSA runs a 'one-document' rule for battery water-to-water transhipment: if the cargo report is made at the port of loading, only a ship report is needed at the transhipment port. Cargo barged into Ningbo can therefore avoid a second cargo report, provided the first one was filed correctly.
What Anxin does: When cargo starts on a feeder or barge, we make sure the cargo report is filed at the first port of loading and carries the ocean routing, so no second cargo report is needed at Ningbo.
The Atlantic hurricane season, covering the Caribbean and the Gulf of America, runs from 1 June to 30 November, peaking around 10 September, with an average of 14 named storms. Ports on the way to Martha's Vineyard close ahead of storms, and ships wait or divert.
What Anxin does: For August–October arrivals we build slack into delivery plans and pass the carrier's revised arrival straight to your consignee.
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 Martha's Vineyard 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.
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 Martha's Vineyard, and chase any missing invoice or HTS detail while the ship is still at sea.
If a battery container waits at Martha's Vineyard, 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
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

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 Ningbo 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
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Uneven load rejected at the Ningbo packing check | Beilun / Meishan stuffing | Load plan checked before stuffing | Packing site, checked by Anxin |
| Hurricane closes ports or diverts the vessel | Caribbean / Gulf, Jun–Nov | Slack in delivery plan | Carrier / consignee |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
Questions
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.
1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.
Zhejiang MSA's 2026 guide says the cargo weight in any half of the container's length should not exceed 60% of the total, with every package braced and checked for damage and marks.
