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 Qingdao
Qingdao to Viana do Castelo
Yellow Sea · Taiwan Strait · Malacca Strait · Indian Ocean · Bab-el-Mandeb · Suez Canal · Sicily Channel · Strait of Gibraltar
This route runs from Shandong through Qingdao's Qianwan terminals, where Qingdao MSA pilots one-document transhipment, then follows a Bab el-Mandeb and Suez passage into the Mediterranean; at the far end is the port of Viana do Castelo.
On the Portuguese side, APA's SILiAmb register and the EU importer checks both apply. 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
Loading port first, then the sea leg, then Viana do Castelo and the Portugal market.
Shandong MSA has issued a waterway safe-transport guide specifically for lithium battery energy storage systems at Shandong coastal ports, so ESS units shipped from Qingdao should be prepared with that provincial guide in mind as well as the IMDG Code.
What Anxin does: For ESS cargo we review the unit's packing and securing plan against the Shandong guide with the packing site before booking.
Services that avoid the Red Sea, 43% of the Mediterranean total, go round the Cape of Good Hope and re-enter through Gibraltar. SAMSA estimates that about 200 of the 576 containers lost at sea in 2024, 35% of the total, went overboard near the Cape.
What Anxin does: On Cape sailings we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
Importers must make sure batteries come with instructions and safety information in a language end-users in Portugal easily understand, as that Member State decides. Printed inserts and carton text are far easier to change before the goods are packed in China.
What Anxin does: We ask the importer which language Portugal requires and check carton and insert photos against it before loading.
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.
Two marking dates fall into current shipping plans for Portugal: the general label from 18 August 2026 and the QR code from 18 February 2027, which for EV, LMT and larger industrial batteries has to open the battery passport.
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.

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 Qingdao 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 |
|---|---|---|---|
| Heavy weather off South Africa on a Cape sailing | Cape of Good Hope | CINS stuffing checks | Packing site, checked by Anxin |
| Importer not registered on SILiAmb | Importer in Portugal | Registration confirmed before booking | Importer |
| Stock shipped without the label due from August 2026 | Importer in Portugal | Label status confirmed before booking | Manufacturer / 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.
Under Qingdao MSA's 'one-document, one-box' pilot (since November 2024), water-to-water transhipment between Dagang and Qianwan needs one outbound cargo report and at most one packing inspection. We confirm eligibility at booking.

We check carrier acceptance for Qingdao → Viana do Castelo before any booking, and ask for missing battery documents first.
