Lithium batteries for Porto go out of Lianyungang, where the MSA simplified 'new three' filings in 2024. On the way they face a Bab el-Mandeb and Suez passage into the Mediterranean, and they arrive 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.
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
They run from the Lianyungang terminal through the voyage to Porto and the Portugal import file.
The China Meteorological Administration describes sea fog as a major marine hazard in the Yellow and Bohai Seas, mainly from April to July. At Lianyungang, as at Qingdao, fog can hold vessels at anchor, and a changed vessel means amended DG filings.
What Anxin does: In fog season we keep slack between stuffing and the DG cut-off and have the filing data ready to amend.
The JMIC's September 2026 update rated the northern Red Sea and Suez Canal MODERATE, with the canal operating in both directions and container lines returning selectively, and the Eastern Mediterranean LOW. The risk on this corridor is concentrated at the southern entrance of the Red Sea rather than at the canal.
What Anxin does: We check before each booking whether the service has changed routing since the last quote.
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.
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.
For portable batteries, Annex I sets maximum levels of 0.0005 % mercury, 0.002 % cadmium and 0.01 % lead by weight, the lead limit applying since 18 August 2024. The importer in Portugal may be asked by market surveillance to demonstrate compliance.
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.

Documents & compliance
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.

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 Lianyungang 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 |
|---|---|---|---|
| Importer not registered on SILiAmb | Importer in Portugal | Registration confirmed before booking | Importer |
Questions
ADR, which the EU applies to domestic journeys through Directive 2008/68/EC. UN 3480 is class 9, transport category 2, with tunnel restriction code (E).
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.
Its June 2025 break-bulk ESS guide recommends 20–50% remaining charge, with converters and monitoring off and circuits disconnected.

We check carrier acceptance for Lianyungang → Porto before any booking, and ask for missing battery documents first.
