Asia – Baltic via the Danish straits
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.

From Shenzhen to Swinoujscie, cargo moves from Dongguan and Shenzhen factories via Yantian, crosses a long Europe voyage extended through the Danish straits into the Baltic, and is discharged at the port of Swinoujscie.
The Polish side adds the BDO number to the EU battery rules. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.

Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Swinoujscie and at customs in Poland.
Much Shenzhen battery export is stuffed inland and trucked to the terminal. In May 2026 Yantian MSA and Dongguan MSA ran a cross-regional 'one-box' pilot: four battery containers were inspected jointly at the Dongguan factory and loaded at Yantian without being opened again. It shows that the inspection record made at the factory is what matters at the terminal.
What Anxin does: We ask at booking whether your factory and the terminal's MSA office can use the one-box arrangement, and we have stuffing photos, the packing certificate and the DG declaration match exactly, so the container is not held for re-inspection.
Because Swinoujscie is an EU port, container ships of 5,000 GT or more calling there fall under the EU Emissions Trading System, which covers half the emissions of the voyage from China. Lines surrendered allowances for 70% of those emissions in 2025 and must cover 100% from 2027, a cost that can reach shippers as a surcharge.
What Anxin does: We ask for the emissions surcharge to be shown as its own line in the quote, with the basis the carrier uses, so that successive quotes can be compared like for like.
For Swinoujscie, EU security pre-filing happens at the other end of the voyage: the ICS2 entry summary must reach the system 24 hours before the container is loaded in Shenzhen. No filing means no loading, and a missing EORI number is enough to reject it.
What Anxin does: We collect the consignee's EORI number, an HS-level goods description and the house-bill parties at booking, and make sure the party filing the ENS has them before the Shenzhen cut-off.
Once the container leaves the terminal by road, ADR applies: Directive 2008/68/EC makes EU countries use it for domestic dangerous goods journeys as well as international ones. UN 3480 is class 9, transport category 2, with tunnel restriction code (E), so the haulier in Poland has to plan around category E tunnels, and damaged or defective batteries fall under special provision 376 and packing instructions P908 or P911 instead of P903.
What Anxin does: We give the Poland haulier the same UN number, class and package details that appear on the sea dangerous goods declaration, so the ADR transport document matches the container paperwork from Shenzhen.
A battery entering Poland has to identify its importer: name, registered trade name or trade mark, postal address and a contact point belong on the battery itself, or on the packaging or accompanying document when the battery is too small. That text is fixed at the factory, not at Swinoujscie.
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.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

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 |
|---|---|---|---|
| Container reopened at the terminal because records do not match | Factory → Yantian | Photos, packing certificate and DG declaration cross-checked before trucking | Anxin |
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line | Carrier, checked by Anxin |
| ENS not filed and the box is refused at loading | Loading port, Shenzhen | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
| Road route planned through a category E tunnel | Road leg from Swinoujscie | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
The importer's: name, registered trade name or trade mark and postal address with a contact point, on the battery or, if it is too small, on the packaging or accompanying document.
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.
Yes, provided a certified packing inspector supervises the stuffing and signs the container packing certificate. Since May 2026 Yantian and Dongguan MSA have also piloted joint factory inspection so the container can be loaded at Yantian without reopening; we check whether your shipment can use it.
