Lithium batteries for Astoria go from Dongguan and Shenzhen factories via Yantian, where the one-box route had moved 409 battery containers by September 2026. On the way they face a North Pacific corridor with no canal or chokepoint, and they arrive at the port of Astoria.

Astoria means US customs filings that are due while the container is still in Shenzhen, and a supply chain CBP may ask to see. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.

Route profile

The Shenzhen → Astoria route in brief

Sea corridor

Transpacific (North Pacific)

A North Pacific crossing with no canal or chokepoint risk, but with a record of winter storms strong enough to collapse container stacks.

Import country

United States

Two filings before loading, a Section 301 line set by classification, UFLPA supply-chain questions and a 15-day General Order clock after discharge.

Where this route gets difficult

Where Shenzhen → Astoria shipments get held up: 5 points

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

Origin port
Dongguan's packaging certificate data is shared
Dongguan, home to more than 500 battery companies, supplies much of the cargo leaving Shenzhen. Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data, described as a first in China, and act jointly against concealed and false declarations; the one-box route to Yantian, 409 containers by then, relies on the same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
Sea corridor
Hurricane-force winter storms, October to April
NOAA's Ocean Prediction Center has recorded hurricane-force winds (64 knots or more) in mid-latitude North Pacific storms in every month from October to April, most often in December, with 15 to 23 such storms a season in its 2001–2004 study. These are not tropical systems, so they arrive outside typhoon season.
What Anxin does: For October–April sailings we check blocking and bracing on stuffing photos before sealing and confirm the full DG data are on the manifest.
Import country
AMS: the manifest CBP sees before the ship leaves Shenzhen
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 Astoria 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 Shenzhen, so the AMS filing and the DG manifest say the same thing.
Import country
A US-only carton mark for SP188 shipments
Packages of UN3480 or UN3090 moving under IMDG special provision 188 skip the DG declaration at sea, yet 49 CFR 171.25(b)(3) still wants the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' mark or a Cargo Aircraft Only label on each one, and on packages of batteries with or in equipment over 5 kg net.
What Anxin does: When the shipper declares SP188 for a Astoria booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
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 Astoria 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 Shenzhen, rather than leaving it for re-marking in a US warehouse.

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 Shenzhen export filings, the carrier booking and the United States import papers. We compare all three before confirming space.

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 Shenzhen to Astoria

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.

Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.

Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
