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 Ningbo to Porto, cargo moves through Ningbo's Beilun or Meishan terminals under Zhejiang MSA's 2026 battery guide, 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 adds its SILiAmb register to the EU Battery Regulation duties. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
What we need to start
Route profile
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.
Portugal's SILiAmb register at APA on top of EU duties: CE marking, the 2026 label and 2027 QR code, and ADR for the road leg.


Where this route gets difficult
Loading port first, then the sea leg, then Porto and the Portugal market.
Zhejiang MSA's January 2026 battery guide sets a concrete loading test: no half of the container's length may carry more than 60% of the cargo weight, and packages must be braced. On board, deck stowage should be inside fire-fighting coverage and shaded from direct sun, and under-deck stowage in holds with temperature probes.
What Anxin does: We ask for the load plan before stuffing and check the 60% split on the stuffing photos, and we pass the shading and away-from-heat stowage request to the carrier on the booking.
Asia–Mediterranean services used the Red Sea 57% of the time in September 2026 according to Sea-Intelligence, compared with 27% for North Europe, so a box for Porto most probably goes via Suez and through Bab el-Mandeb. The JMIC rated that strait SUBSTANTIAL on 24 September 2026; the Houthis call their blockade selective and 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.
Sea cargo for the EU needs a complete Entry Summary Declaration under ICS2 Release 3, and for deep-sea containers it is due 24 hours before loading at the departure port. Carriers apply 'no manifest, no load', and a filing without a valid EORI number is rejected, so a data gap in Ningbo leaves the box on the quay.
What Anxin does: We collect the consignee's EORI number, an HS-level goods description and the house-bill parties at booking, and make sure the party filing the ENS has them before the Ningbo cut-off.
Importers placing batteries on the market in Portugal register with the Portuguese Environment Agency (APA) on SILiAmb and submit an annual declaration by 31 March that includes batteries built into other products. They meet their responsibility through a licensed management entity such as Electrão, or through 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.
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
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.

A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Ningbo export filings, the carrier booking and the Portugal import papers. We compare all three before confirming space.
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 |
|---|---|---|---|
| Uneven load rejected at the Ningbo packing check | Beilun / Meishan stuffing | Load plan checked before stuffing | Packing site, checked by 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 |
| Importer not registered on SILiAmb | Importer in Portugal | Registration confirmed before booking | Importer |
| ENS not filed and the box is refused at loading | Loading port, Ningbo | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
Questions
It registers with APA on the SILiAmb platform, files an annual declaration by 31 March, and joins a licensed management entity or runs an APA-authorised individual system.
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.
Zhejiang MSA's 2026 guide says the cargo weight in any half of the container's length should not exceed 60% of the total, with every package braced and checked for damage and marks.
