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.

This route runs through Guangzhou's Nansha terminals, which since September 2026 accept Dongguan-inspected battery boxes without a second check, then follows a Bab el-Mandeb and Suez passage into the Mediterranean; at the far end is the port of Viana do Castelo.
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
- Typhoon season Jun–Oct
- Nansha export
- Portuguese-language safety information
- Consignee EORI
- EU declaration of conformity
Route profile
What sets Guangzhou → Viana do Castelo apart
Portugal
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
Where Guangzhou → Viana do Castelo shipments get held up: 5 points
In the order the cargo meets them: at the loading port, at sea, at Viana do Castelo and at customs in Portugal.
- Origin port
Customs and MSA now compare packaging certificates
In September 2026 Dongguan Customs and Dongguan MSA started sharing dangerous-goods packaging certificate data, described as a first in China, together with joint action against concealed and false declarations; Huangpu Customs also runs a joint 'lithium batteries going overseas' service against misdeclaration. A packaging certificate that does not match the MSA filing is now visible to both agencies.
What Anxin does: We check that the UN number, packaging code and quantities on the packaging certificate are exactly those on the MSA cargo report before either is submitted.
- Sea corridor
Mediterranean services are back in the Red Sea more than others
Sea-Intelligence data for September 2026 show 57% of Asia–Mediterranean services routed via the Red Sea, against 27% for North Europe. For Viana do Castelo 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 Viana do Castelo uses and name it on the quote, together with any war-risk or emergency surcharge.
- Import country
SILiAmb registration with APA and a licensed entity
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.
- Import country
CE marking and a declaration of conformity in the right language
Since 18 August 2024 a battery sold in the EU needs the CE marking and an EU declaration of conformity from its manufacturer. The declaration has to be available in the language Portugal requires, and the importer is the one who must check both before the goods are released for sale.
What Anxin does: We ask the manufacturer in China for the declaration of conformity and a photo of the CE marking on the battery or its packaging before loading, and pass them to the Portugal importer. We check that the documents exist and match the goods; we do not assess conformity.
- Import country
The ICS2 entry summary is due before loading in Guangzhou
For Viana do Castelo, EU security pre-filing happens at the other end of the voyage: the ICS2 entry summary must reach the system 24 hours before the container is loaded in Guangzhou. No filing means no loading, and a missing EORI number is enough to reject it.
What Anxin does: We collect the consignee's EORI number, an HS-level goods description and the house-bill parties at booking, and make sure the party filing the ENS has them before the Guangzhou cut-off.
Documents & compliance
What to have ready: Guangzhou to Viana do Castelo
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.
In Guangzhou, before the box is loaded
- Packaging certificate and MSA cargo report cross-checked line by line (UN number, packaging code, quantity)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
- Transport-condition classification report where applicable
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
- EU declaration of conformity and CE marking photo from the manufacturer
For the shipping line
- Routing (Red Sea or Cape) and any war-risk surcharge stated on the booking
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
- Consignee EORI and HS-level description to the ENS filer before loading
At the Portugal end
- APA (SILiAmb) registration and management entity of the Portuguese producer
- Instructions and safety information in the language Portugal requires
- Haulier in Portugal briefed with UN number, class 9 and tunnel code (E) for the road leg
Before you book
One consistent file
A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Guangzhou export filings, the carrier booking and the Portugal import papers. We compare all three before confirming space.
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.

| Mismatch between packaging certificate and MSA filing flagged by shared data | Dongguan / Nansha | Line-by-line check before submission | 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 |

| Declaration of conformity missing or not in the required language | Importer in Portugal | Declaration and CE photo collected before loading | Manufacturer / importer |
Questions
Common questions on the Guangzhou → Viana do Castelo route
24 hours before the container is loaded in China, not before it reaches Viana do Castelo. 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.
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.
