This route runs from factories around the Pearl River Delta through Yantian or Shekou, then follows a Suez corridor that Mediterranean services are using again more than any other Asia–Europe lane; at the far end is the port of Sesimbra.
The Portuguese side adds SILiAmb registration to the EU battery rules. 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
Pearl River Delta battery cargo, often stuffed at factories in Dongguan or Huizhou, exported through Yantian or Shekou, with a typhoon season from June to October.
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
Loading port first, then the sea leg, then Sesimbra and the Portugal market.
Much of Shenzhen's battery cargo is made in Dongguan, home to more than 500 battery firms. In September 2026 Dongguan Customs and Dongguan MSA began sharing dangerous-goods packaging certificate data, described as a first in China, and committed to joint action against concealed and false declarations. The one-box route to Yantian, which had moved 409 containers by then, rests on that same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
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.
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.
For Sesimbra, 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 Shenzhen. 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 Shenzhen cut-off.
Road delivery from Sesimbra is an ADR movement, because the EU applies ADR to domestic journeys through Directive 2008/68/EC. For UN 3480 that means class 9, transport category 2 and tunnel code (E), which restricts the route through category E tunnels; batteries found damaged at unloading move to special provision 376 packing (P908 or P911).
What Anxin does: We give the Portugal haulier the same UN number, class and package details that appear on the sea dangerous goods declaration, so the ADR transport document matches the container paperwork from Shenzhen.

Documents & compliance
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; 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 Shenzhen 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 |
|---|---|---|---|
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | Anxin with the declarant |
| ENS not filed and the box is refused at loading | Loading port, Shenzhen | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
| Road route planned through a category E tunnel | Road leg from Sesimbra | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
| Storage system delivered without Annex V test file | Buyer in Portugal | Test documentation confirmed before booking | Manufacturer |
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.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
