Lithium batteries for Nazaré go through Dayaowan, where Liaoning's first JT/T 1543 lithium export sailed in May 2025. On the way they face a Bab el-Mandeb and Suez passage into the Mediterranean, and they arrive at the port of Nazaré.
Portugal adds its SILiAmb register to the EU Battery Regulation duties. Below are 6 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
North-east China's battery gateway at Dayaowan, with a small but growing lithium export flow, a local MSA that has named misdeclaration as its main problem, and both winter ice and spring fog.
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.


Where this route gets difficult
Listed from loading in Dalian to import into Portugal, each with what we do about it.
Liaoning's first lithium battery export under JT/T 1543 sailed from Dayaowan on 4 May 2025, and Dalian MSA counted 885 TEU of lithium batteries exported in the first four months of that year. Carriers should not accept batteries that do not meet JT/T 1543, and with a thinner flow there are fewer sailings to fall back on if a booking is refused.
What Anxin does: We check JT/T 1543 conformity evidence with the manufacturer before booking and confirm the carrier's acceptance of the UN numbers in writing.
Sea ice forms every winter in the Bohai Sea and northern Yellow Sea. In winter 2021/22 China's marine forecast centre expected floating ice about 15 nautical miles out in the northern Yellow Sea, where Dalian's Dayaowan lies, and about 60 in Liaodong Bay, peaking from mid-January to mid-February.
What Anxin does: For January–February sailings from Dalian we allow extra time between stuffing and the DG cut-off and reconfirm the vessel schedule the week before loading.
Sea-Intelligence data for September 2026 show 57% of Asia–Mediterranean services routed via the Red Sea, against 27% for North Europe. For Nazaré 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 Nazaré uses and name it on the quote, together with any war-risk or emergency surcharge.
Stationary battery energy storage systems placed on the EU market since 18 August 2024 must be safe in normal operation, with technical documentation showing tests against the Annex V parameters, including thermal shock, short-circuit protection, over-discharge and thermal propagation. ESS buyers in Portugal increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Portugal we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.
The Battery Regulation's general information label applies from 18 August 2026 (or 18 months after the label implementing act, if later), and every battery needs a QR code from 18 February 2027, linked to a battery passport for EV, LMT and industrial batteries above 2 kWh. Where the battery is too small, both go on the packaging and accompanying documents.
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.
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
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

We line up UN numbers, model names and package counts across the Dalian 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 Nazaré.
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 |
|---|---|---|---|
| Ice delays berthing in mid-winter | Northern Yellow Sea, Jan–Feb | Extra time before cut-off; schedule reconfirmed | Carrier, monitored 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 |
| Stock shipped without the label due from August 2026 | Importer in Portugal | Label status confirmed before booking | Manufacturer / importer |
| Storage system delivered without Annex V test file | Buyer in Portugal | Test documentation confirmed before booking | Manufacturer |
Questions
The importer's: name, registered trade name or trade mark and postal address with a contact point, on the battery or, if it is too small, on the packaging or accompanying document.
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.
Sea ice forms every winter in the northern Yellow Sea; in 2021/22 it was forecast to reach about 15 nautical miles out there, peaking mid-January to mid-February. We plan extra time for those weeks.
