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 Dalian to Ronne, cargo moves from Liaoning through Dalian's Dayaowan terminals, crosses a long Europe voyage extended through the Danish straits into the Baltic, and is discharged at the port of Ronne.
Denmark registers battery producers through Dansk Producentansvar. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.

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.

Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Ronne and at customs in Denmark.
The Bohai Sea and the northern Yellow Sea freeze every winter. For 2021/22 China's marine forecast centre expected floating ice around 15 nautical miles offshore in the northern Yellow Sea, where Dayaowan is, and around 60 in Liaodong Bay, with the peak between mid-January and mid-February.
What Anxin does: For January–February sailings from Dalian we allow extra time between stuffing and the DG cut-off and reconfirm the vessel schedule the week before loading.
According to Dayaowan MSA in April 2024, lithium battery cargo was often under-declared or misdeclared because the rules are complicated. It responded with a dedicated desk and hotline, priority for EV batteries, and AI-based document comparison intended to reduce container openings, which means any mismatch between the declaration and its supporting papers gets flagged.
What Anxin does: We reconcile the UN number, classification, packing group, quantity and SDS across every document before filing, which is exactly what an automated comparison will test.
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.
The importer in Denmark carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Denmark 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 Denmark importer. We check that the documents exist and match the goods; we do not assess conformity.
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 Denmark 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 Denmark 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 Dalian.

Documents & compliance
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

We line up UN numbers, model names and package counts across the Dalian filings, the booking with the carrier and the documents for Denmark before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Ronne.
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 |
|---|---|---|---|
| Declaration flagged by document comparison; container opened | Dayaowan | Cross-document reconciliation before filing | Anxin with the declarant |
| Ice delays berthing in mid-winter | Northern Yellow Sea, Jan–Feb | Extra time before cut-off; schedule reconfirmed | Carrier, monitored by Anxin |
| Declaration of conformity missing or not in the required language | Importer in Denmark | Declaration and CE photo collected before loading | Manufacturer / importer |
| Road route planned through a category E tunnel | Road leg from Ronne | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
In the producer responsibility register at Dansk Producentansvar, via virk.dk. Foreign companies selling directly to end-users need a Danish authorised representative.
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.
Sea ice forms every winter in the northern Yellow Sea; in 2021/22 it was forecast to reach about 15 nautical miles out there, peaking mid-January to mid-February. We plan extra time for those weeks.

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