This route runs through Ningbo-Zhoushan, where Zhejiang MSA's guide sets a 60% weight-balance test for battery containers, then follows the Pacific, the Panama Canal and the Caribbean; at the far end is the port of Port Arthur.
Port Arthur means US customs filings that are due while the container is still in Ningbo, and a supply chain CBP may ask to see. 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
- Zhejiang MSA battery guide 2026
- Beilun / Meishan export
- Supply-chain tracing file
- HTS code 8507.60

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

Zhejiang's weight-balance and stowage rules
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.
- 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.

SP188 packages need an extra US marking
Small cells and batteries shipped under IMDG special provision 188 do not need a dangerous goods declaration at sea, but 49 CFR 171.25(b)(3) adds a US condition: each package of UN3480 or UN3090 must carry the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so must packages of batteries with or in equipment above 5 kg net. Cartons printed for other markets often lack it.
What Anxin does: When the shipper declares SP188 for a Port Arthur booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Port Arthur without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
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.

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

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 Ningbo 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.
Risk & mitigation

Questions
Common questions on the Ningbo → Port Arthur route
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.
It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.
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.
