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.

This route runs out of Tianjin's Xingang terminals, where customs can supervise stuffing at the factory and the box goes straight to the ship on a booked slot, 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 Tavira.

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.

Where this route gets difficult
Listed from loading in Tianjin to import into Portugal, each with what we do about it.
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.
Tianjin MSA itself said in July 2026 that, under the traditional review model, long document reviews often made firms miss the vessel's document cut-off, leaving cargo in port to be re-allocated to another ship. Its new fast-track green channel (appointment-based, more than 50% faster, with a fixed document list) is for new-energy-vehicle cargo; battery shipments should not assume they qualify.
What Anxin does: We submit the cargo report with the full document set (safe-carriage declaration, SDS, packing certificate, packaging certificate) days before the cut-off rather than on the day, and treat any MSA query as same-day work.
Ships of 5,000 GT and above calling at EU ports, Tavira 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.
Since 18 August 2024 a battery sold in the EU needs the CE marking and an EU declaration of conformity from its manufacturer. The declaration has to be available in the language Portugal requires, and the importer is the one who must check both before the goods are released for sale.
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.
Two marking dates fall into current shipping plans for Portugal: the general label from 18 August 2026 and the QR code from 18 February 2027, which for EV, LMT and larger industrial batteries has to open the battery passport.
What Anxin does: Before booking we ask the Portugal importer to confirm the battery category and whether the label and QR-code elements are already on the goods, and compare carton photos with that answer.

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 Tavira.
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 |
|---|---|---|---|
| Document review runs past the vessel cut-off; cargo re-allocated to a later ship | Tianjin MSA review | Complete document set filed days before cut-off | Anxin with the declarant |
| 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 |
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line with its basis | Carrier, 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 |
| Stock shipped without the label due from August 2026 | Importer in Portugal | Label status confirmed before booking | Manufacturer / importer |
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).
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.
The green channel Tianjin MSA announced in July 2026 is for new-energy-vehicle cargo. For battery containers we plan on the normal review and file early, because Tianjin MSA has said long reviews under the traditional model often cost firms their vessel cut-off.
