Lithium batteries for Olhão go from North China through Tianjin Xingang. On the way they face a lane whose routing, Suez or Cape of Good Hope, is decided service by service, and they arrive at the port of Olhão.
The Portuguese side adds SILiAmb registration to the EU battery rules. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
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.
SILiAmb registration with APA and an annual declaration, a licensed management entity or approved individual system, and the EU-wide battery and ICS2 duties.


Where this route gets difficult
They run from the Tianjin terminal through the voyage to Olhão and the Portugal import file.
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.
Routing round Africa takes battery boxes past the Cape. The World Shipping Council counted 576 containers lost at sea in 2024, and the South African Maritime Safety Authority estimates around 200 of them, about 35%, were lost near the Cape; in August 2024 SAMSA reported 99 boxes lost from the CMA CGM Belem off Richards Bay and 46 from the MSC Antonio off Port St Johns in winter weather.
What Anxin does: When the booking goes via the Cape, we apply the CINS stuffing checks (gaps, blocking, wall clearance) more strictly and ask for photos at every stage of packing.
The importer in Portugal carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Portugal 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 Portugal 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 Portugal 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 Portugal 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 Tianjin.
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 Portugal increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Portugal 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
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.

Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Tianjin filings, the carrier booking and the Portugal import file. We check the three against each other before the booking is confirmed.
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 |
| Heavy weather off South Africa | Cape of Good Hope | CINS stuffing and blocking checks before sealing | Packing site, checked by Anxin |
| Declaration of conformity missing or not in the required language | Importer in Portugal | Declaration and CE photo collected before loading | Manufacturer / importer |
| Road route planned through a category E tunnel | Road leg from Olhão | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
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.
It depends on the service. In September 2026 most Asia–North Europe capacity still sailed round the Cape of Good Hope; Sea-Intelligence put the Red Sea share for North Europe vessels at 27%. We ask the carrier to confirm the routing on the booking and quote each routing separately.
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.
