Tianjin (Xingang)
North China's main container gateway, where Tianjin Customs lets DG containers be inspected at the factory and loaded on arrival within a booked port slot, and where the Bohai Bay freezes at its edges in mid-winter.

From Tianjin to Rostock, cargo moves through Tianjin, with its Beijiang and Dongjiang terminals on the Bohai Bay, crosses a Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and is discharged at the port of Rostock.
Germany expects the battery to be registered, labelled and pre-declared before it is loaded in China. 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
North China's main container gateway, where Tianjin Customs lets DG containers be inspected at the factory and loaded on arrival within a booked port slot, and where the Bohai Bay freezes at its edges in mid-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 Rostock and at customs in Germany.
Tianjin Customs runs a 'supervised factory loading, direct loading on port arrival' model for dangerous goods: officers oversee stuffing at the factory, the declaration goes in early through the single window, and the container enters the port in a slot booked on the customs–port platform and goes straight to the ship. Any inspection happens in closed yards inside the Beijiang and Dongjiang terminals. The time saved depends on the stuffing date, the slot and the declared data all matching.
What Anxin does: We fix the stuffing date against the vessel's DG cut-off first, then book the entry slot, and check that the declaration, the packing certificate and the container number agree before the truck leaves, so the box is not diverted to an inspection yard for a data mismatch.
Cargo for Rostock 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.
Whoever first makes batteries available in Germany is the producer and must hold a registration with stiftung ear for each brand and battery category. A non-German brand cannot register itself; it needs one authorised representative in Germany. Since 1 January 2026 every category must also be linked to an approved producer responsibility organisation (OfH), and registrations that were not updated by 15 January 2026 were withdrawn by law.
What Anxin does: We ask who acts as producer for this shipment (importer, brand owner or authorised representative) and for the Batt-Reg.-Nr. DE before the container is booked, so the question is answered while the goods are still in China.
The importer in Germany carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Germany 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 Germany importer. We check that the documents exist and match the goods; we do not assess conformity.
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 Tianjin 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 |
|---|---|---|---|
| Box sent to the terminal inspection yard because declared data do not match | Beijiang / Dongjiang terminals | Declaration, packing certificate and container number cross-checked before trucking | Anxin |
| Feeder operator does not accept the UN numbers | North Sea hub | DG acceptance for the feeder leg confirmed | Anxin with the carrier |
| Batteries arrive without a valid German producer registration | Placing on the German market after clearance | Batt-Reg.-Nr. DE and OfH status requested before booking; shipment planned only once the producer role is clear | Importer / producer |
| Declaration of conformity missing or not in the required language | Importer in Germany | Declaration and CE photo collected before loading | Manufacturer / importer |
Questions
The importer's: name, registered trade name or trade mark and postal address with a contact point, on the battery or, if it is too small, on the packaging or accompanying document.
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.
Tianjin Customs offers a 'supervised factory loading, direct loading on port arrival' model: stuffing is supervised at the factory, the box enters the port in a booked slot and is loaded directly. Whether a given shipment can use it depends on the customs arrangement for the exporter and the port slot; we check both when you book.
