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.

Lithium batteries for Naantali go from North China through Tianjin Xingang. On the way they face a long Europe voyage extended through the Danish straits into the Baltic, and they arrive at the port of Naantali.
Finland keeps its battery producers in a national register at the Finnish Supervisory Agency. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.
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.
Registration in the Finnish Supervisory Agency's producer register, a Finnish authorised representative for distance sellers, and EU importer duties such as CE marking and the importer's details on the battery.


Where this route gets difficult
Loading port first, then the sea leg, then Naantali and the Finland market.
In July 2026 Tianjin MSA acknowledged that long document reviews under its traditional model often caused firms to miss the vessel's document cut-off, leaving cargo in port for another ship. The new appointment-based green channel, more than 50% faster with a fixed document list, is for new-energy-vehicle cargo; battery shipments should not count on it.
What Anxin does: We submit the cargo report with the full document set (safe-carriage declaration, SDS, packing certificate, packaging certificate) days before the cut-off rather than on the day, and treat any MSA query as same-day work.
Ships of 5,000 GT and above calling at EU ports, Naantali included, are in the EU Emissions Trading System: 50% of the emissions of a voyage from China are covered, and the share of emissions for which lines must surrender allowances rises from 70% (for 2025 emissions) to 100% from 2027. Carriers can pass that cost on 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.
Producer responsibility for batteries in Finland runs through the national producer register, now held by the Finnish Supervisory Agency. A seller abroad that ships directly to Finnish customers must appoint an authorised representative established in Finland, and a producer organisation can take that role.
What Anxin does: We ask whether the Finnish consignee or a foreign seller is the producer of record, and for the register details, before booking.
Since 18 August 2024 a battery sold in the EU needs the CE marking and an EU declaration of conformity from its manufacturer. The declaration has to be available in the language Finland requires, and the importer is the one who must check both before the goods are released for sale.
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 Finland importer. We check that the documents exist and match the goods; we do not assess conformity.
For Naantali, 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 Tianjin. 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 Tianjin cut-off.

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.

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 Tianjin filings, the carrier booking and the Finland 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 |
|---|---|---|---|
| Document review runs past the vessel cut-off; cargo re-allocated to a later ship | Tianjin MSA review | Complete document set filed days before cut-off | Anxin with the declarant |
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line | Carrier, checked by Anxin |
| Distance seller with no Finnish authorised representative | Finnish producer register | Producer role confirmed at booking | Seller / importer |
| Declaration of conformity missing or not in the required language | Importer in Finland | Declaration and CE photo collected before loading | Manufacturer / importer |
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.
Yes, but in the restriction period only ships of the required ice class and deadweight receive icebreaker assistance. Finland's agency publishes the restrictions on baltice.org, with exemption requests due at least three working days before arrival.
The green channel Tianjin MSA announced in July 2026 is for new-energy-vehicle cargo. For battery containers we plan on the normal review and file early, because Tianjin MSA has said long reviews under the traditional model often cost firms their vessel cut-off.

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