Asia – Mediterranean via Suez
Mediterranean services are the ones most likely to use Suez again (57% in September 2026), which puts the cargo back through Bab el-Mandeb, rated a SUBSTANTIAL threat.

From Shenzhen to Porto, cargo moves from Dongguan and Shenzhen factories via Yantian, crosses a Suez corridor that Mediterranean services are using again more than any other Asia–Europe lane, and is discharged at the port of Porto.
Portugal registers battery producers with APA on SILiAmb. Below are 5 route-specific points to plan for, what we do about each, and the documents to have ready before booking.

Where this route gets difficult
What to watch between Shenzhen and Porto: 5 points
Listed from loading in Shenzhen to import into Portugal, each with what we do about it.
- Origin port
Factory stuffing in Dongguan, loading at Yantian: avoid a second opening
Much Shenzhen battery export is stuffed inland and trucked to the terminal. In May 2026 Yantian MSA and Dongguan MSA ran a cross-regional 'one-box' pilot: four battery containers were inspected jointly at the Dongguan factory and loaded at Yantian without being opened again. It shows that the inspection record made at the factory is what matters at the terminal.
What Anxin does: We ask at booking whether your factory and the terminal's MSA office can use the one-box arrangement, and we have stuffing photos, the packing certificate and the DG declaration match exactly, so the container is not held for re-inspection.
- Sea corridor
Mediterranean services are back in the Red Sea more than others
Sea-Intelligence data for September 2026 show 57% of Asia–Mediterranean services routed via the Red Sea, against 27% for North Europe. For Porto the Suez routing is therefore the likely one, and it runs through Bab el-Mandeb, which the JMIC rated SUBSTANTIAL on 24 September 2026: the Houthis describe their blockade as selective, and they now hold Perim Island in the channel.
What Anxin does: We ask the carrier which routing its service to Porto uses and name it on the quote, together with any war-risk or emergency surcharge.
- Import country
CE marking and a declaration of conformity in the right language
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.
- Import country
The importer's name and address on the battery
The Battery Regulation asks the importer to put its own name, registered trade name or trade mark and postal address, with a single contact point, on the battery. Only when the battery's size or nature makes that impossible may the details move to the packaging or an accompanying document, so a Portugal importer's details need to reach the factory before printing.
What Anxin does: We pass the Portugal importer's name and address block to the manufacturer before the goods are packed in China and check carton or battery photos for it before loading.
- Import country
The truck leg out of Porto runs under ADR
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 Shenzhen.
Documents & compliance
What to have ready: Shenzhen to Porto
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.
In Shenzhen, before the box is loaded
- Confirmation from the carrier of the DG cut-off at Yantian or Shekou, rechecked in typhoon weeks
- Annex V safety documentation confirmed for stationary storage systems
- Substance declaration covering mercury, cadmium and lead limits
- 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)
For the shipping line
- Routing (Red Sea or Cape) and any war-risk surcharge stated on the booking
- Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
At the Portugal end
- Haulier in Portugal briefed with UN number, class 9 and tunnel code (E) for the road leg
- Instructions and safety information in the language Portugal requires
- APA (SILiAmb) registration and management entity of the Portuguese producer
Before you book
Send the file once, complete
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 Shenzhen 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 table for Shenzhen → Porto
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Container reopened at the terminal because records do not match | Factory → Yantian | Photos, packing certificate and DG declaration cross-checked before trucking | Anxin |
| Security incident near Bab el-Mandeb changes the routing or adds surcharges | Southern Red Sea | Routing and surcharges stated in writing before booking | 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 |
| Road route planned through a category E tunnel | Road leg from Porto | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
Common questions on the Shenzhen → Porto route
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.
Often: in September 2026, 57% of Asia–Mediterranean services used the Red Sea routing. Bab el-Mandeb was rated a SUBSTANTIAL threat by the JMIC on 24 September 2026, so we confirm each service's routing before booking.
Yes, provided a certified packing inspector supervises the stuffing and signs the container packing certificate. Since May 2026 Yantian and Dongguan MSA have also piloted joint factory inspection so the container can be loaded at Yantian without reopening; we check whether your shipment can use it.
