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 Lubeck, cargo moves from factories around the Pearl River Delta through Yantian or Shekou, crosses a long Europe voyage extended through the Danish straits into the Baltic, and is discharged at the port of Lubeck.
The German side adds producer registration with stiftung ear and the EU Battery Regulation's labelling calendar. 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
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.
EU Battery Regulation labelling and QR-code dates, stiftung ear registration under the BattDG, and an ICS2 entry summary that must exist before the box is loaded.


Where this route gets difficult
Listed from loading in Shenzhen to import into Germany, each with what we do about it.
Dongguan, home to more than 500 battery companies, supplies much of the cargo leaving Shenzhen. Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data, described as a first in China, and act jointly against concealed and false declarations; the one-box route to Yantian, 409 containers by then, relies on the same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
Every box for Lubeck 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.
EU pre-arrival security filing moved to ICS2 Release 3: sea cargo needs a complete Entry Summary Declaration, and forwarders issuing house bills of lading have had to file or pass house-level data since 1 April 2025. For deep-sea containers the ENS is due 24 hours before loading at the departure port, and carriers apply 'no manifest, no load'. A missing EORI number is enough for the filing to be rejected.
What Anxin does: We collect the consignee's EORI number, a goods description at HS level and the house-level parties at booking, and make sure they reach whoever files the ENS ahead of the Shenzhen loading cut-off.
Road delivery from Lubeck is an ADR movement, because the EU applies ADR to domestic journeys through Directive 2008/68/EC. For UN 3480 that means class 9, transport category 2 and tunnel code (E), which restricts the route through category E tunnels; batteries found damaged at unloading move to special provision 376 packing (P908 or P911).
What Anxin does: We give the Germany 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 Shenzhen.
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 Germany increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Germany we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Shenzhen export filings, the carrier booking and the Germany import papers. We compare all three before confirming space.
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 |
|---|---|---|---|
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | 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 |
| ENS not lodged in time | Loading port in China | House-level data and EORI collected at booking and passed to the filer ahead of the loading cut-off | Anxin with the ENS filer |
| Road route planned through a category E tunnel | Road leg from Lubeck | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
The registration is needed before the batteries are first made available on the German market, by whoever is the producer for that market. A company without a German establishment has to act through one authorised representative in Germany, and since 2026 each battery category must also be covered by an approved OfH. Shipping can start earlier, but goods without a valid registration cannot be sold in Germany once they arrive, so we ask for the registration number at booking.
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.
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.

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