Lithium batteries for Gdansk go through Dayaowan, where Liaoning's first JT/T 1543 lithium export sailed in May 2025. On the way they face a Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and they arrive at a Baltic port where the harbour master sets conditions for handling each dangerous-goods cargo.
Poland expects the importer to hold a BDO register entry for batteries. This page sets out 6 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
Route profile
North-east China's battery gateway at Dayaowan, with a small but growing lithium export flow, a local MSA that has named misdeclaration as its main problem, and both winter ice and spring fog.
The Baltic is reached only through the Danish straits, where deep-draught ships are advised to take pilots, and its northern ports set ice-class restrictions every winter.


Where this route gets difficult
Loading port first, then the sea leg, then Gdansk and the Poland market.
Sea ice forms every winter in the Bohai Sea and northern Yellow Sea. In winter 2021/22 China's marine forecast centre expected floating ice about 15 nautical miles out in the northern Yellow Sea, where Dalian's Dayaowan lies, and about 60 in Liaodong Bay, peaking from mid-January to mid-February.
What Anxin does: For January–February sailings from Dalian we allow extra time between stuffing and the DG cut-off and reconfirm the vessel schedule the week before loading.
Before the Danish straits, the voyage from Asia is the same as for North Europe: Sea-Intelligence data for September 2026 put Red Sea routing at 27% for North Europe services, so most boxes still go round the Cape of Good Hope, where SAMSA estimates about 35% of 2024's lost containers went overboard.
What Anxin does: We quote the Suez and Cape routings separately when both are offered and apply the CINS stuffing checks strictly on Cape sailings.
In the ports supervised by the Maritime Office in Gdynia, the dangerous goods on an arriving ship are declared through the National Single Window at least 24 hours ahead, or on departure from the previous port on a short leg, which is common for Baltic feeders. The harbour master then gives consent and sets conditions for entry and handling.
What Anxin does: Because most Chinese cargo reaches Gdansk by feeder, we check the DG data are final before the mainline ship leaves Dalian, so the feeder's declaration is not built on a draft.
The importer in Poland carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Poland asks for, have both been required since 18 August 2024 for batteries entering the EU market.
What Anxin does: We ask the manufacturer in China for the declaration of conformity and a photo of the CE marking on the battery or its packaging before loading, and pass them to the Poland importer. We check that the documents exist and match the goods; we do not assess conformity.
Poland tracks battery introducers through the BDO waste database: an importer needs its entry in the battery section before placing batteries on the market, and the BDO number goes on the documents used to trade them. Buyers often check for it on the invoice.
What Anxin does: We ask the Polish importer for its BDO number and put it on the commercial documents we prepare with the shipper.
Article 11 of the Battery Regulation says that from 18 February 2027 portable batteries inside appliances must be readily removable and replaceable by the end-user using commercially available tools, without heat or solvents, except under limited derogations. Appliances sold in Poland after that date need a design that complies.
What Anxin does: When appliances with built-in batteries are booked for Poland we point the importer to the February 2027 date so the manufacturer answers the design question before shipment; we do not assess compliance.

Documents & compliance
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.

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 Dalian filings, the carrier booking and the Poland 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 |
|---|---|---|---|
| Ice delays berthing in mid-winter | Northern Yellow Sea, Jan–Feb | Extra time before cut-off; schedule reconfirmed | Carrier, monitored by Anxin |
| Feeder's declaration differs from the mainline booking | Port of Gdansk | DG data final before the mainline departure | Carrier / agent |
| Importer without a BDO entry for batteries | Importer in Poland | BDO number confirmed before booking | Importer |
| Declaration of conformity missing or not in the required language | Importer in Poland | Declaration and CE photo collected before loading | Manufacturer / importer |
Questions
An entry in the BDO register as a business introducing batteries, obtained before placing them on the market. Its BDO number goes on the trading documents.
Often, but it depends on the service. The Baltic is reached through the Danish straits, and we ask the carrier to name any transhipment port and confirm DG acceptance for each vessel.
Sea ice forms every winter in the northern Yellow Sea; in 2021/22 it was forecast to reach about 15 nautical miles out there, peaking mid-January to mid-February. We plan extra time for those weeks.

We check carrier acceptance for Dalian → Gdansk before any booking, and ask for missing battery documents first.
