Asia – Baltic via the Danish straits
The Baltic is reached only through the Danish straits, where deep-draught ships are advised to take pilots, and its northern ports set ice-class restrictions every winter.

This route runs through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules, then follows a Suez-or-Cape voyage that ends with the Danish straits and the Baltic; at the far end is the port of Swinoujscie.
The Polish side adds the BDO number to the EU battery rules. The 6 points below are particular to this lane; each comes with what we do and the paperwork it touches.

Where this route gets difficult
Loading port first, then the sea leg, then Swinoujscie and the Poland market.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration from the stuffing company, but places the burden on the shipper: the batteries must meet the UN tests and be protected against damage, short circuit and accidental activation, and MSA runs spot checks during and after the process, with proof to be produced on request.
What Anxin does: We keep a file per container (UN38.3 summary, SDS, packing photos, terminal protection details) so that proof can be produced the same day if Shanghai MSA asks for it after sailing.
Shanghai MSA's 2024 draft reporting guide says warehouses that stuff lithium battery dangerous goods must provide fire-department proof of their fire hazard classification and fire-resistance rating. The site's information must also be up to date on the Shanghai single window, which took over MSA account and site records in 2026.
What Anxin does: We only propose stuffing sites that can show the fire-safety documents and are on Shanghai MSA's system; if you use your own warehouse, we check this before booking.
Because Swinoujscie is an EU port, container ships of 5,000 GT or more calling there fall under the EU Emissions Trading System, which covers half the emissions of the voyage from China. Lines surrendered allowances for 70% of those emissions in 2025 and must cover 100% from 2027, a cost that can reach shippers as a surcharge.
What Anxin does: We ask for the emissions surcharge to be shown as its own line in the quote, with the basis the carrier uses, so that successive quotes can be compared like for like.
The importer in Poland carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Poland asks for, have both been required since 18 August 2024 for batteries entering the EU market.
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 Poland importer. We check that the documents exist and match the goods; we do not assess conformity.
Sea cargo for the EU needs a complete Entry Summary Declaration under ICS2 Release 3, and for deep-sea containers it is due 24 hours before loading at the departure port. Carriers apply 'no manifest, no load', and a filing without a valid EORI number is rejected, so a data gap in Shanghai leaves the box on the quay.
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 Shanghai cut-off.
Two marking dates fall into current shipping plans for Poland: 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 Poland 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 Shanghai filings, the carrier booking and the Poland 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 |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line | Carrier, checked by Anxin |
| Declaration of conformity missing or not in the required language | Importer in Poland | Declaration and CE photo collected before loading | Manufacturer / importer |
| ENS not filed and the box is refused at loading | Loading port, Shanghai | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
Questions
24 hours before the container is loaded in China, not before it reaches Swinoujscie. Without it carriers do not load the box, and a filing without an EORI number is rejected.
Often, but it depends on the service. The Baltic is reached through the Danish straits, and we ask the carrier to name any transhipment port and confirm DG acceptance for each vessel.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration issued by the stuffing company. Either way, the shipper remains responsible and must provide proof if MSA spot-checks.
