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.

Lithium batteries for Lisbon go out of Nansha, at the mouth of the Pearl River. On the way they face a Bab el-Mandeb and Suez passage into the Mediterranean, and they arrive at the port of Lisbon.
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.
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 Lisbon and the Portugal market.
The Hong Kong Observatory puts the region's tropical cyclone season from June to October, busiest July to September. Nansha sits at the mouth of the Pearl River; a closed gate or a changed vessel means the DG filings and the packing certificate have to follow the box to a new sailing.
What Anxin does: From June to October we leave slack between stuffing and the DG cut-off at Nansha and refile quickly if the vessel changes.
Sea-Intelligence data for September 2026 show 57% of Asia–Mediterranean services routed via the Red Sea, against 27% for North Europe. For Lisbon 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 Lisbon uses and name it on the quote, together with any war-risk or emergency surcharge.
Annex I of the Battery Regulation caps mercury at 0.0005 %, cadmium at 0.002 % and lead at 0.01 % by weight in portable batteries, and the lead limit has applied since 18 August 2024. Market surveillance in Portugal can ask the importer to show that the goods meet these limits.
What Anxin does: We ask the manufacturer for its substance declaration or test report reference and file it with the shipping documents for the Portugal importer; we do not test batteries.
Anyone placing batteries on the Portuguese market, importers included, registers with the Portuguese Environment Agency on SILiAmb and files an annual declaration by 31 March, counting batteries built into other products. Responsibility is met through a licensed management entity such as Electrão, or 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.
The Battery Regulation's due diligence obligations on cobalt, lithium, nickel and natural graphite were postponed by Regulation (EU) 2025/1561 and now apply from 18 August 2027, with Commission guidelines due by 26 July 2026. Buyers in Portugal are already asking suppliers for the supply-chain data they will need.
What Anxin does: We pass the Portugal buyer's due diligence questions to the manufacturer and keep their answers with the shipment file; the policy itself remains the producer's responsibility.

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.

We line up UN numbers, model names and package counts across the Guangzhou filings, the booking with the carrier and the documents for Portugal before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Lisbon.
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 |
|---|---|---|---|
| Typhoon closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| 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 |
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.
Nansha MSA has recommended around 25% for ESS batteries and measures against accidental activation. Treat it as the local authority's recommendation; the carrier's own acceptance conditions also apply.
