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 Shanghai, where MSA spot-checks battery containers during and after filing, then follows a Suez-or-Cape voyage that ends with the Danish straits and the Baltic; at the far end is 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.
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 with Dansk Producentansvar via virk.dk, a Danish authorised representative for foreign sellers, and the EU-wide battery and ICS2 duties.


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.
Shanghai MSA's Notice No. 4 of 2024 lets the shipper use either an inspector-signed packing certificate or a packing declaration from the stuffing company, but the responsibility stays with the shipper: UN-tested batteries, protected against damage, short circuit and accidental activation. MSA spot-checks during and after the process and can ask for proof.
What Anxin does: We keep a file per container (UN38.3 summary, SDS, packing photos, terminal protection details) so that proof can be produced the same day if Shanghai MSA asks for it after sailing.
Every box for Ronne passes the Danish straits, where IMO recommends pilotage on Route T for ships with a draught of 11 m or more and the Danish Maritime Authority reports non-compliant ships to their flag state. If the container is moved to a feeder at a North Sea port, that second vessel must also 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.
Since 18 August 2025 Danish battery producers register with Dansk Producentansvar through virk.dk, declaring expected quantities and chemistries. A foreign company selling straight to Danish end-users must appoint a Danish authorised representative, who confirms the registration and, for portable and LMT batteries, joins a collective scheme on its behalf.
What Anxin does: We ask the Danish buyer whether it or a foreign seller is the producer, and for the registration reference, before booking.
Stationary battery energy storage systems placed on the EU market since 18 August 2024 must be safe in normal operation, with technical documentation showing tests against the Annex V parameters, including thermal shock, short-circuit protection, over-discharge and thermal propagation. ESS buyers in Denmark increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Denmark we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.
Regulation (EU) 2025/1561 pushed the Battery Regulation's due diligence duties for cobalt, lithium, nickel and natural graphite back to 18 August 2027 and gave the Commission until 26 July 2026 for its guidelines. Buyers in Denmark are already collecting the supply-chain information they will need.
What Anxin does: We pass the Denmark buyer's due diligence questions to the manufacturer and keep their answers with the shipment file; the policy itself remains the producer's responsibility.

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 Shanghai 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 |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Feeder operator does not accept the UN numbers | North Sea hub | DG acceptance for the feeder leg confirmed | Anxin with the carrier |
| Foreign seller without a Danish authorised representative | Danish producer register | Producer role and representative confirmed at booking | Seller / importer |
| Storage system delivered without Annex V test file | Buyer in Denmark | Test documentation confirmed before booking | Manufacturer |
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.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration issued by the stuffing company. Either way, the shipper remains responsible and must provide proof if MSA spot-checks.

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