Portugal adds its SILiAmb register to the EU Battery Regulation duties. 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
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.
SILiAmb registration with APA and an annual declaration, a licensed management entity or approved individual system, and the EU-wide battery and ICS2 duties.


Where this route gets difficult
Listed from loading in Dalian to import into Portugal, each with what we do about it.
Dayaowan MSA reported in April 2024 that omissions and misdeclarations of lithium battery cargo were frequent because the rules are complex. Its answer was a dedicated desk and hotline, priority handling for EV batteries, and AI comparison of documents to cut down container openings: a comparison that flags any gap between the declaration and the paperwork behind it.
What Anxin does: We reconcile the UN number, classification, packing group, quantity and SDS across every document before filing, which is exactly what an automated comparison will test.
The China Meteorological Administration describes sea fog as a major marine hazard in the Yellow and Bohai Seas, with the season mainly from April to July, seriously affecting sea transport. Fog holds keep vessels at anchor, and a late vessel can push the box past its documented sailing.
What Anxin does: In the fog season we avoid tight stuffing-to-cut-off gaps and keep the filing data ready to amend if the vessel changes.
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 Vila Real de Santo António 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 Vila Real de Santo António uses and name it on the quote, together with any war-risk or emergency surcharge.
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.
From 18 February 2027, Article 11 requires portable batteries built into appliances to be readily removable and replaceable by the end-user with commercially available tools, without heat or solvents, apart from limited derogations. Appliances shipped to Portugal for sale after that date need a design that meets the rule.
What Anxin does: When appliances with built-in batteries are booked for Portugal we point the importer to the February 2027 date so the manufacturer answers the design question before shipment; we do not assess compliance.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; 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 Dalian 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 |
|---|---|---|---|
| Declaration flagged by document comparison; container opened | Dayaowan | Cross-document reconciliation before filing | Anxin with the declarant |
| Fog hold delays the vessel; filings need amending | Yellow Sea, Apr–Jul | Amendment-ready filing data | 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 |
| Stock shipped without the label due from August 2026 | Importer in Portugal | Label status confirmed before booking | Manufacturer / importer |
Questions
24 hours before the container is loaded in China, not before it reaches Vila Real de Santo António. Without it carriers do not load the box, and a filing without an EORI number is rejected.
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.
Dayaowan MSA reported in 2024 that omissions and misdeclarations of lithium battery cargo were frequent because the rules are complex, and it uses AI document comparison. Consistent data across the declaration, SDS and packing documents is the main defence.
