Lithium batteries for Gdynia go out of Shenzhen's Yantian and Shekou terminals. On the way they face a long Europe voyage extended through the Danish straits into the Baltic, and they arrive at a Baltic port where the harbour master sets conditions for handling each dangerous-goods cargo.
The Polish side adds the BDO number to the EU battery rules. 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
Pearl River Delta battery cargo, often stuffed at factories in Dongguan or Huizhou, exported through Yantian or Shekou, with a typhoon season from June to October.
Dangerous goods declared through Poland's National Single Window 24 hours before arrival, with the harbour master's consent and conditions for handling.


Where this route gets difficult
Loading port first, then the sea leg, then Gdynia and the Poland market.
Much of Shenzhen's battery cargo is made in Dongguan, home to more than 500 battery firms. In September 2026 Dongguan Customs and Dongguan MSA began sharing dangerous-goods packaging certificate data, described as a first in China, and committed to joint action against concealed and false declarations. The one-box route to Yantian, which had moved 409 containers by then, rests on that 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.
The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
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 Gdynia by feeder, we check the DG data are final before the mainline ship leaves Shenzhen, so the feeder's declaration is not built on a draft.
The Battery Regulation asks the importer to put its own name, registered trade name or trade mark and postal address, with a single contact point, on the battery. Only when the battery's size or nature makes that impossible may the details move to the packaging or an accompanying document, so a Poland importer's details need to reach the factory before printing.
What Anxin does: We pass the Poland importer's name and address block to the manufacturer before the goods are packed in China and check carton or battery photos for it before loading.
Importers must make sure batteries come with instructions and safety information in a language end-users in Poland easily understand, as that Member State decides. Printed inserts and carton text are far easier to change before the goods are packed in China.
What Anxin does: We ask the importer which language Poland requires and check carton and insert photos against it before loading.

Documents & compliance
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

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 Poland 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
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | Anxin with the declarant |
| Feeder's declaration differs from the mainline booking | Port of Gdynia | DG data final before the mainline departure | Carrier / agent |
| Importer details missing from battery and packaging | Importer in Poland | Address block sent to the factory before packing | Manufacturer / importer |
Questions
The CE marking on the battery and the manufacturer's EU declaration of conformity, which must be available in the language Poland requires. Both have applied since 18 August 2024.
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.
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.

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