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.
Europe · sea freight from Ningbo
Ningbo to Viana do Castelo
East China Sea · Taiwan Strait · Malacca Strait · Indian Ocean · Bab-el-Mandeb · Suez Canal · Sicily Channel · Strait of Gibraltar
From Ningbo to Viana do Castelo, cargo moves through Ningbo-Zhoushan, crosses a Suez corridor that Mediterranean services are using again more than any other Asia–Europe lane, and is discharged at the port of Viana do Castelo.
The Portuguese side adds SILiAmb registration to the EU battery rules. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.
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.
An annual SILiAmb declaration, a licensed management entity or individual system, and EU importer duties from the declaration of conformity to the importer's address on the battery.


Where this route gets difficult
They run from the Ningbo terminal through the voyage to Viana do Castelo and the Portugal import file.
Zhejiang MSA's January 2026 battery guide lets the shipper skip the UN38.3 test summary at the MSA cargo-report stage (it goes to the carrier instead) and skip resubmitting the safety data sheet for the same maker, owner and model. The carrier, however, must still check the documents and refuse batteries that do not meet the ship-carriage standard JT/T 1543-2025.
What Anxin does: We send the UN38.3 summary and SDS to the carrier with the booking request, and keep a per-model file so repeat shipments use the SDS already on record.
Ships of 5,000 GT and above calling at EU ports, Viana do Castelo 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.
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.
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.
An importer has to ensure that batteries are accompanied by instructions and safety information in a language that end-users in Portugal can easily understand, as the Member State determines. Inserts and carton print are much simpler to adjust before packing in China.
What Anxin does: We ask the importer which language Portugal requires and check carton and insert photos against it before loading.

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 Ningbo 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 | Where | Mitigation | Who acts |
|---|---|---|---|
| Carrier rejects booking over UN38.3 / JT/T 1543-2025 documents | Ningbo booking stage | UN38.3 summary and SDS sent with the booking request | Shipper with Anxin |
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line | 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 |
| Importer details missing from battery and packaging | Importer in Portugal | Address block sent to the factory before packing | Manufacturer / importer |
Questions
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. Zhejiang MSA's 2026 guide removed it from the MSA cargo-report stage, but it still has to go to the carrier, which must refuse batteries that do not meet JT/T 1543-2025.
