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 Sundsvall, cargo moves from Dongguan and Shenzhen factories via Yantian, crosses a Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and is discharged at the port of Sundsvall.
Sweden has required producer registration with Naturvårdsverket since January 2026. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
- Yantian / Shekou export
- Typhoon season Jun–Oct
- Consignee EORI
- EU declaration of conformity

Where this route gets difficult
5 points to plan for on the Shenzhen → Sundsvall route
They run from the Shenzhen terminal through the voyage to Sundsvall and the Sweden import file.
- Origin port
Typhoon season squeezes Shenzhen cut-offs
The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
- Sea corridor
Through the Danish straits, possibly on a feeder
Cargo for Sundsvall has to pass the Danish straits. IMO recommends pilots on Route T for ships of 11 m draught or more, and the Danish Maritime Authority reports ships that ignore the recommendation to their flag state. Whether the box stays on one vessel or is transhipped onto a feeder at a North Sea port, each vessel has to accept the UN numbers.
What Anxin does: We ask the carrier to name any transhipment port and the feeder operator on the booking and confirm DG acceptance for that leg as well as the mainline.
- Import country
CE marking and a declaration of conformity in the right language
The importer in Sweden carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Sweden asks for, have both been required since 18 August 2024 for batteries entering the EU market.
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 Sweden importer. We check that the documents exist and match the goods; we do not assess conformity.
- Import country
Naturvårdsverket registration since January 2026
Sweden's supplementary ordinance to the Battery Regulation (SFS 2025:813) has required battery producers to be registered with Naturvårdsverket since 1 January 2026. A producer responsibility organisation such as El-Kretsen can help with the filing, but the data remain the producer's responsibility.
What Anxin does: We ask the Swedish importer to confirm the registration is in place before booking, and pass on battery chemistry and weight data it may need for reporting.
- Import country
The importer's name and address on the battery
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 Sweden importer's details need to reach the factory before printing.
What Anxin does: We pass the Sweden 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.

Before you book
Send the file once, complete
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 Shenzhen filings, the carrier booking and the Sweden 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 table for Shenzhen → Sundsvall
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Feeder operator does not accept the UN numbers | North Sea hub | DG acceptance for the feeder leg confirmed | Anxin with the carrier |
| Producer not yet registered with Naturvårdsverket | Importer in Sweden | Registration confirmed before booking | Importer |
| Declaration of conformity missing or not in the required language | Importer in Sweden | Declaration and CE photo collected before loading | Manufacturer / importer |
Questions
Shenzhen → Sundsvall: questions we are asked
Yes. Since 1 January 2026 producers, which includes importers placing batteries on the Swedish market, must be registered with Naturvårdsverket under Ordinance 2025:813.
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.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
