Asia – North & Atlantic Europe
The map shows the Suez corridor, but in September 2026 most Asia–North Europe capacity still sails round the Cape of Good Hope.

Lithium batteries for Swansea go through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules. 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 Swansea.
British importers report battery tonnage and chemistry each year and need a CDS subscription for customs. 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
- Photo-verified packing certificate
- Yangshan / Waigaoqiao export
- Consignee EORI
- EU declaration of conformity
- BPRN
Route profile
What sets Shanghai → Swansea apart
United Kingdom
UK producer registration, a compliance scheme for portable batteries above 1 tonne a year, and import clearance through HMRC's Customs Declaration Service.
Where this route gets difficult
What to watch between Shanghai and Swansea: 5 points
Listed from loading in Shanghai to import into United Kingdom, each with what we do about it.
- Origin port
Not every Shanghai warehouse can stuff lithium DG
Shanghai MSA's 2024 draft reporting guide says warehouses that stuff lithium battery dangerous goods must provide fire-department proof of their fire hazard classification and fire-resistance rating. The site's information must also be up to date on the Shanghai single window, which took over MSA account and site records in 2026.
What Anxin does: We only propose stuffing sites that can show the fire-safety documents and are on Shanghai MSA's system; if you use your own warehouse, we check this before booking.
- Sea corridor
Container losses off South Africa
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.
- Import country
Mercury, cadmium and lead under UK rules
Batteries sold in the UK may contain no more than 0.0005 % mercury and 0.002 % cadmium by weight, subject to listed exceptions, and those above 0.004 % lead need the Pb symbol beneath the bin symbol. The Office for Product Safety and Standards enforces the rules.
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.
- Import country
Harbour master notice a day ahead under DGHAR
Under the Dangerous Goods in Harbour Areas Regulations 2016, dangerous goods may not enter a British harbour area unless the harbour master has had notice at least 24 hours (and at most six months) in advance, or has agreed a shorter period. UN numbers, names and quantities are part of that notice, so the vessel's report is only as good as the booking data.
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.
- Import country
Bin symbol and capacity label under the 2008 regulations
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 Shanghai, because relabelling after discharge at Swansea means opening dangerous goods packages.
Documents & compliance
What to have ready: Shanghai to Swansea
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.
At the Shanghai end
- Stuffing site registered and geo-verified with Shanghai MSA; fire-safety proof for lithium DG warehouses
- Crossed-out bin symbol and mAh/Ah capacity label checked on battery and packaging photos
- Substance statement for mercury, cadmium and lead from the manufacturer
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
Carrier and voyage
- Routing (Suez or Cape of Good Hope) and any transhipment port stated on the booking confirmation
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
At the United Kingdom end
- Battery weight and chemistry per shipment for the importer's NPWD return
- Importer's GB or XI EORI and CDS subscription confirmed; declarant named
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Shanghai filings, the booking with the carrier and the documents for United Kingdom before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Swansea.
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
What could go wrong from Shanghai to Swansea, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Heavy weather off South Africa | Cape of Good Hope | CINS stuffing and blocking checks before sealing | Packing site, checked by Anxin |
| Harbour notice late or wrong | Swansea 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
Shanghai → Swansea: questions we are asked
HMRC's Customs Declaration Service. The importer or agent needs a GB (or XI) EORI number and a CDS subscription; HMRC grants access within 2 hours or up to 5 working days.
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.
It can, but Shanghai MSA checks the phone location of the packing photos against a verified stuffing site, and sites outside Shanghai must be registered with it. We confirm registration before the stuffing date; otherwise the container can be refused for loading.
