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.

This route runs out of Xiamen's Haicang and Songyu terminals on the Taiwan Strait, then follows a Suez-or-Cape voyage that ends with the Danish straits and the Baltic; at the far end is the port of Sundsvall.
The Swedish side adds the Naturvårdsverket register 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.
Naturvårdsverket registration under Ordinance 2025:813 since 1 January 2026, plus EU duties from CE marking to ADR on the road leg.


Where this route gets difficult
Loading port first, then the sea leg, then Sundsvall and the Sweden market.
Ships leaving Xiamen enter the Taiwan Strait straight away. A Chinese government weather account notes that the strait's funnel effect makes winds 1–2 Beaufort levels stronger than outside it, and that the winter and spring north-east monsoon brings force 7 or stronger winds on about two-thirds of days. Container ships are advised to secure lashing.
What Anxin does: From October to April we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
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 Sundsvall in the restriction period.
What Anxin does: For winter shipments we check the restrictions in force on baltice.org for Sundsvall and ask the carrier to confirm that the final feeder has the required ice class before we book.
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 Sweden 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 Sweden 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 Xiamen.
Since 18 August 2024 a stationary battery energy storage system placed on the EU market must be safe in normal operation, and its technical documentation must show testing against the Annex V safety parameters, from thermal shock and short-circuit protection to over-discharge and thermal propagation. Buyers of ESS cabinets in Sweden increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Sweden we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.
From 18 February 2027, Article 11 requires portable batteries built into appliances to be readily removable and replaceable by the end-user with commercially available tools, without heat or solvents, apart from limited derogations. Appliances shipped to Sweden for sale after that date need a design that meets the rule.
What Anxin does: When appliances with built-in batteries are booked for Sweden we point the importer to the February 2027 date so the manufacturer answers the design question before shipment; we do not assess compliance.

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 Xiamen filings, the booking with the carrier and the documents for Sweden before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Sundsvall.
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 |
|---|---|---|---|
| Cargo shift in winter monsoon seas | Taiwan Strait, Oct–Apr | CINS blocking and bracing checked on photos | Packing site, checked by Anxin |
| Feeder lacks the ice class required under winter restrictions | Northern Baltic, winter | Ice class confirmed at booking | Carrier, checked by Anxin |
| Road route planned through a category E tunnel | Road leg from Sundsvall | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
| Storage system delivered without Annex V test file | Buyer in Sweden | 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.
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. Xiamen MSA reported 104 ESS containers of 36 tonnes each loaded for Houston in June 2026. Xiamen's ESS guide 2.0 requires a pre-voyage meeting and use of a class 9 qualified terminal.
