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.

Lithium batteries for Holyhead go from North China through Tianjin Xingang. On the way they face a voyage that may run through Suez as drawn or round the Cape, depending on the service, and they arrive at the port of Holyhead.
Great Britain runs its own post-Brexit pre-filing and battery producer rules. Below are 6 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.
The map shows the Suez corridor, but in September 2026 most Asia–North Europe capacity still sails round the Cape of Good Hope.


Where this route gets difficult
They run from the Tianjin terminal through the voyage to Holyhead and the United Kingdom import file.
In July 2026 Tianjin MSA acknowledged that long document reviews under its traditional model often caused firms to miss the vessel's document cut-off, leaving cargo in port for another ship. The new appointment-based green channel, more than 50% faster with a fixed document list, is for new-energy-vehicle cargo; battery shipments should not count on it.
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.
Every winter the Bohai Sea ices over, and the Haihe estuary at Tianjin is one of the harder-hit areas. For 2021/22 the national marine forecast centre put the peak ice period between mid-January and mid-February, with floating ice about 5 nautical miles out in Bohai Bay. Ice and cold slow port work just as the Chinese New Year peak arrives.
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.
The map on this page shows the corridor through Bab-el-Mandeb and Suez, but Sea-Intelligence figures for September 2026 put Red Sea routing on the Asia–Europe head-haul at 13–25%, with 27% for North Europe services and 57% for the Mediterranean. The service that calls at Holyhead decides between Suez and the Cape of Good Hope, and with it the distance, the waters and the possible transhipment ports.
What Anxin does: We ask the carrier to state the routing and any transhipment port on the booking confirmation, and we quote the two routings separately when both are on offer rather than mixing them.
Great Britain still labels batteries under the Batteries and Accumulators (Placing on the Market) Regulations 2008: a crossed-out wheeled bin symbol of a set minimum size on every battery, moved to the packaging only when the battery is too small or cannot practically be marked, and a capacity in mAh or Ah on portable rechargeables and on the front of their packaging.
What Anxin does: We compare carton and battery photos with the UK marking list before goods leave Tianjin, because relabelling after discharge at Holyhead means opening dangerous goods packages.
The Dangerous Goods in Harbour Areas Regulations 2016 bar bringing dangerous goods into a British harbour area without notice to the harbour master at least 24 hours ahead (and no more than six months), unless the harbour master agrees a shorter period. The notice carries UN numbers, names and quantities, so the vessel's data depend on the booking.
What Anxin does: We freeze the UN number, proper shipping name, package count and gross weight on the booking before departure and send any change to the carrier at once.
The UK limits mercury to 0.0005 % and cadmium to 0.002 % by weight in batteries, with listed exceptions, and a battery with more than 0.004 % lead must show the symbol Pb below the bin symbol. OPSS enforces these rules for batteries sold in the UK.
What Anxin does: We ask the manufacturer for a substance statement covering mercury, cadmium and lead and file it with the shipment documents for the UK importer; we do not test batteries.

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 United Kingdom 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 |
|---|---|---|---|
| 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 |
| Service switches between Suez and Cape routing | Main voyage | Routing written on the booking; quotes kept separate per routing; packing assumes the longer voyage | Carrier, tracked by Anxin |
| Harbour notice late or wrong | Holyhead harbour area | DG data frozen before departure | Carrier / agent |
| Batteries arrive without the bin symbol or capacity marking | Importer in the UK | Photos checked against the UK marking list before loading | Manufacturer / importer |
Questions
The crossed-out wheeled bin symbol at a minimum size, on the packaging if the battery is too small, and for portable rechargeables a capacity in mAh or Ah on the battery and the packaging front.
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.
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.
