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.

Lithium batteries for Stralsund go from the Pearl River Delta via Nansha. On the way they face a Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and they arrive at the port of Stralsund.
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
In the order the cargo meets them: at the loading port, at sea, at Stralsund and at customs in Germany.
Nansha MSA told a July 2024 meeting on energy-storage carriage that ESS batteries should travel at roughly 25% state of charge, with accidental activation prevented. It is advice, not a binding rule, yet it is the number the local authority has put on the record.
What Anxin does: For ESS cargo leaving Nansha we ask the manufacturer to state the shipping state of charge and the anti-activation measures in writing, and put both in the documents the carrier sees.
Ships of 5,000 GT and above calling at EU ports, Stralsund included, are in the EU Emissions Trading System: 50% of the emissions of a voyage from China are covered, and the share of emissions for which lines must surrender allowances rises from 70% (for 2025 emissions) to 100% from 2027. Carriers can pass that cost on as a surcharge.
What Anxin does: We ask for the emissions surcharge to be shown as its own line in the quote, with the basis the carrier uses, so that successive quotes can be compared like for like.
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 Guangzhou loading cut-off.
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.
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 Germany for sale after that date need a design that meets the rule.
What Anxin does: When appliances with built-in batteries are booked for Germany 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
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

We line up UN numbers, model names and package counts across the Guangzhou filings, the booking with the carrier and the documents for Germany before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Stralsund.
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 |
|---|---|---|---|
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line | Carrier, checked by Anxin |
| 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 |
| Storage system delivered without Annex V test file | Buyer in Germany | Test documentation confirmed before booking | Manufacturer |
Questions
ADR, which the EU applies to domestic journeys through Directive 2008/68/EC. UN 3480 is class 9, transport category 2, with tunnel restriction code (E).
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.
Nansha MSA has recommended around 25% for ESS batteries and measures against accidental activation. Treat it as the local authority's recommendation; the carrier's own acceptance conditions also apply.

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