Dalian (Dayaowan)
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.

Lithium batteries for Cadiz 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 Cadiz.
Spain wants the producer on the RII-PYA register, with its number on the invoice. 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.
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 Spain, 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 JMIC's September 2026 update put the northern Red Sea and the Suez Canal at MODERATE, with two-way transits and container lines selectively returning, and the Eastern Mediterranean at LOW. On this corridor the exposure lies at the southern entrance of the Red Sea, not at the canal itself.
What Anxin does: We check before each booking whether the service has changed routing since the last quote.
Two marking dates fall into current shipping plans for Spain: 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 Spain 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.
For Cadiz, 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 Dalian. 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 Dalian cut-off.
Loose cells and batteries built into electrical equipment, removable or not, both fall under the Spanish register. Declarations are quarterly, errors can be corrected until 25 January of the following year, and changes to registration data must be updated within a month.
What Anxin does: When batteries travel inside devices we list battery quantity and chemistry separately on the packing list, so the importer can report them without reopening cartons.

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 Spain before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Cadiz.
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 |
| Embedded batteries left out of the quarterly declaration | Importer in Spain | Battery data on the packing list | Importer |
| ENS not filed and the box is refused at loading | Loading port, Dalian | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
| Stock shipped without the label due from August 2026 | Importer in Spain | Label status confirmed before booking | Manufacturer / importer |
Questions
The importer, as producer, in the RII-PYA register. A collective scheme may register it on its behalf; otherwise registration is online with an electronic signature or Cl@ve. The registration number must appear on invoices.
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.
