From Lianyungang to Washington DC, cargo moves through Lianyungang port, crosses a Panama Canal corridor whose draft limit depends on Gatun Lake, and is discharged at the port of Washington DC.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.

Route profile
The Lianyungang → Washington DC route in brief
United States
US entry hinges on filings made in China (ISF and AMS), a traceable lithium supply chain and a road leg that is regulated as a hazmat move.
Where this route gets difficult
5 pain points from Lianyungang to Washington DC
In the order the cargo meets them: at the loading port, at sea, at Washington DC and at customs in United States.
- Origin port
Yellow Sea fog from April to July
The China Meteorological Administration describes sea fog as a major marine hazard in the Yellow and Bohai Seas, mainly from April to July. At Lianyungang, as at Qingdao, fog can hold vessels at anchor, and a changed vessel means amended DG filings.
What Anxin does: In fog season we keep slack between stuffing and the DG cut-off and have the filing data ready to amend.
- 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 Washington DC and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
- Import country
ISF closes 24 hours before loading in Lianyungang
The Importer Security Filing must reach CBP no later than 24 hours before the container is laden aboard the vessel abroad. CBP's liquidated damages guidelines provide for a claim per violation for late, inaccurate or incomplete filings. Two of the data elements, the container stuffing location and the consolidator, only exist once the box is packed.
What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Lianyungang, ahead of the vessel's loading window.
- Import country
AMS: the manifest CBP sees before the ship leaves Lianyungang
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 Washington DC 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 Lianyungang, so the AMS filing and the DG manifest say the same thing.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Washington DC 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 Washington DC, and chase any missing invoice or HTS detail while the ship is still at sea.

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 Lianyungang 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 table for Lianyungang → Washington DC
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Draft cut reduces capacity or adds surcharges | Panama Canal | Advisory checked at quotation; carrier confirmation | Carrier, checked by Anxin |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
| Permit to unlade delayed for a late or inaccurate AMS manifest | Port of discharge | Final cargo data given to the carrier before the cut-off | Carrier / NVOCC, with data from Anxin |
Questions
Common questions on the Lianyungang → Washington DC route
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.
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.
Under its Notice No. 1 of 2024, the cargo side submits the DG safe-carriage declaration, the inspector-signed packing certificate, the packaging inspection certificate where the goods are packaged, and a power of attorney.
