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 Ningbo to Ventspils, cargo moves through Ningbo's Beilun or Meishan terminals under Zhejiang MSA's 2026 battery guide, crosses a Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and is discharged at the port of Ventspils.
Latvia applies the EU Battery Regulation, starting with registration in its own national producer register. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.

Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Ventspils and at customs in Latvia.
Zhejiang MSA runs a 'one-document' rule for battery water-to-water transhipment: if the cargo report is made at the port of loading, only a ship report is needed at the transhipment port. Cargo barged into Ningbo can therefore avoid a second cargo report, provided the first one was filed correctly.
What Anxin does: When cargo starts on a feeder or barge, we make sure the cargo report is filed at the first port of loading and carries the ocean routing, so no second cargo report is needed at Ningbo.
Every winter Finland's Transport Infrastructure Agency sets traffic restrictions for its ports: only ships of a stated ice class and deadweight get icebreaker assistance. Exemption requests must be in at least three working days before arrival, and the restrictions for the Baltic are published on baltice.org. A feeder without the right ice class may not be allowed to call at Ventspils in the restriction period.
What Anxin does: For winter shipments we check the restrictions in force on baltice.org for Ventspils and ask the carrier to confirm that the final feeder has the required ice class before we book.
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 Latvia 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 Latvia importer. We check that the documents exist and match the goods; we do not assess conformity.
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 Latvia importer's details need to reach the factory before printing.
What Anxin does: We pass the Latvia 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.
For portable batteries, Annex I sets maximum levels of 0.0005 % mercury, 0.002 % cadmium and 0.01 % lead by weight, the lead limit applying since 18 August 2024. The importer in Latvia may be asked by market surveillance to demonstrate compliance.
What Anxin does: We ask the manufacturer for its substance declaration or test report reference and file it with the shipping documents for the Latvia 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 Ningbo filings, the booking with the carrier and the documents for Latvia before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Ventspils.
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 |
|---|---|---|---|
| Feeder lacks the ice class required under winter restrictions | Northern Baltic, winter | Ice class confirmed at booking | Carrier, checked by Anxin |
| Declaration of conformity missing or not in the required language | Importer in Latvia | Declaration and CE photo collected before loading | Manufacturer / importer |
| Importer details missing from battery and packaging | Importer in Latvia | Address block sent to the factory before packing | Manufacturer / importer |
Questions
ADR, which the EU applies to domestic journeys through Directive 2008/68/EC. UN 3480 is class 9, transport category 2, with tunnel restriction code (E).
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.
Yes. Zhejiang MSA's 2026 guide removed it from the MSA cargo-report stage, but it still has to go to the carrier, which must refuse batteries that do not meet JT/T 1543-2025.

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