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 Lianyungang to Naantali, cargo moves out of Lianyungang, crosses a long Europe voyage extended through the Danish straits into the Baltic, and is discharged at the port of Naantali.
The Finnish side adds producer registration to the EU battery rules. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
Route profile
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.
The national producer register at the Finnish Supervisory Agency, a Finnish authorised representative for distance sellers, and the EU-wide battery and ICS2 duties.


Where this route gets difficult
Listed from loading in Lianyungang to import into Finland, each with what we do about it.
For energy storage shipped on break-bulk vessels, Lianyungang MSA's June 2025 guide classes ESS cabinets as UN3480 and ESS containers as UN3536, recommends 20–50% remaining charge, and requires converters and monitoring switched off, series and parallel circuits disconnected, packages spread evenly with a low centre of gravity, and a safety meeting before the ship arrives.
What Anxin does: For ESS units we confirm the UN number the unit ships under, get the state of charge and isolation steps in writing from the manufacturer, and join the pre-arrival safety meeting with the stowage details.
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.
Stationary battery energy storage systems placed on the EU market since 18 August 2024 must be safe in normal operation, with technical documentation showing tests against the Annex V parameters, including thermal shock, short-circuit protection, over-discharge and thermal propagation. ESS buyers in Finland increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Finland we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.
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 Finland after that date need a design that complies.
What Anxin does: When appliances with built-in batteries are booked for Finland we point the importer to the February 2027 date so the manufacturer answers the design question before shipment; we do not assess compliance.
Annex I of the Battery Regulation caps mercury at 0.0005 %, cadmium at 0.002 % and lead at 0.01 % by weight in portable batteries, and the lead limit has applied since 18 August 2024. Market surveillance in Finland can ask the importer to show that the goods meet these limits.
What Anxin does: We ask the manufacturer for its substance declaration or test report reference and file it with the shipping documents for the Finland importer; we do not test batteries.

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

We line up UN numbers, model names and package counts across the Lianyungang filings, the booking with the carrier and the documents for Finland before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Naantali.
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 |
|---|---|---|---|
| ESS unit not isolated or poorly distributed in a break-bulk hold | Lianyungang, break-bulk loading | Manufacturer's written isolation steps; safety meeting | Manufacturer / ship, coordinated by Anxin |
| Storage system delivered without Annex V test file | Buyer in Finland | Test documentation confirmed before booking | Manufacturer |
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.
Its June 2025 break-bulk ESS guide recommends 20–50% remaining charge, with converters and monitoring off and circuits disconnected.

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