Tianjin to Vila Real de Santo António
Bohai Sea · Bohai Strait · Taiwan Strait · Malacca Strait · Indian Ocean · Bab-el-Mandeb · Suez Canal · Strait of Gibraltar
This route runs from North China through Tianjin Xingang, then follows a voyage that may run through Suez as drawn or round the Cape, depending on the service; at the far end is the port of Vila Real de Santo António.
On the Portuguese side, APA's SILiAmb register and the EU importer checks both apply. 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
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
In the order the cargo meets them: at the loading port, at sea, at Vila Real de Santo António and at customs in Portugal.
Sea ice forms every winter in the Bohai Sea, and the Haihe estuary at Tianjin is among the severe areas. In winter 2021/22 China's national marine forecast centre expected the peak ice period from mid-January to mid-February, with floating ice reaching about 5 nautical miles out in Bohai Bay. Ice and cold spells slow port operations around the Chinese New Year shipping peak.
What Anxin does: For January and February sailings from Tianjin we add slack between stuffing and the DG cut-off and confirm the vessel's berthing window with the carrier the week before loading.
Round-Africa routing puts battery containers through South African waters. Of the 576 containers the World Shipping Council recorded as lost at sea in 2024, the South African Maritime Safety Authority estimates about 200, roughly 35%, went overboard near the Cape. In August 2024 alone, SAMSA reported 99 boxes lost from the CMA CGM Belem off Richards Bay and 46 from the MSC Antonio off Port St Johns in wintry 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.
Anyone placing batteries on the Portuguese market, importers included, registers with the Portuguese Environment Agency on SILiAmb and files an annual declaration by 31 March, counting batteries built into other products. Responsibility is met through a licensed management entity such as Electrão, or an individual system authorised by APA.
What Anxin does: We ask the Portuguese importer for its APA registration and management entity before booking, and list battery weights separately so its declaration is easy.
Road delivery from Vila Real de Santo António 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 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.
The Battery Regulation's due diligence obligations on cobalt, lithium, nickel and natural graphite were postponed by Regulation (EU) 2025/1561 and now apply from 18 August 2027, with Commission guidelines due by 26 July 2026. Buyers in Portugal are already asking suppliers for the supply-chain data they will need.
What Anxin does: We pass the Portugal 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
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

We line up UN numbers, model names and package counts across the Tianjin filings, the booking with the carrier and the documents for Portugal before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Vila Real de Santo António.
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 |
|---|---|---|---|
| Ice or cold spell slows berthing in mid-winter | Bohai Bay, Jan–Feb | Slack between stuffing and cut-off; berthing window reconfirmed | Carrier, monitored by Anxin |
| Heavy weather off South Africa | Cape of Good Hope | CINS stuffing and blocking checks before sealing | Packing site, checked by Anxin |
| Importer not registered on SILiAmb | Importer in Portugal | Registration confirmed before booking | Importer |
| Road route planned through a category E tunnel | Road leg from Vila Real de Santo António | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
The CE marking on the battery and the manufacturer's EU declaration of conformity, which must be available in the language Portugal requires. Both have applied since 18 August 2024.
Ships of 5,000 GT and above calling at EU ports are in the EU Emissions Trading System, covering 50% of the emissions of a voyage from outside the EU. Lines must surrender allowances for 70% of 2025 emissions and 100% from 2027, and may pass the cost on as a surcharge.
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.
