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.

Lithium batteries for Gdansk go out of Shanghai, where MSA spot-checks battery containers during and after filing. On the way they face a long Europe voyage extended through the Danish straits into the Baltic, and they arrive at a Baltic port where the harbour master sets conditions for handling each dangerous-goods cargo.
The Polish side adds the BDO number to the EU battery rules. Below are 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
- Photo-verified packing certificate
- Yangshan / Waigaoqiao export
- BDO number
- Polish-language safety information

Route profile
How Shanghai → Gdansk differs from other lanes
Gdańsk / Gdynia
Dangerous goods declared through Poland's National Single Window 24 hours before arrival, with the harbour master's consent and conditions for handling.
Where this route gets difficult
6 pain points from Shanghai to Gdansk
Listed from loading in Shanghai to import into Poland, each with what we do about it.
- Origin port
Shanghai checks during and after the voyage filing, not just before
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.
- Origin port
Not every Shanghai warehouse can stuff lithium DG
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.
- Sea corridor
The Danish straits and a possible feeder change
Every box for Gdansk passes the Danish straits, where IMO recommends pilotage on Route T for ships with a draught of 11 m or more and the Danish Maritime Authority reports non-compliant ships to their flag state. If the container is moved to a feeder at a North Sea port, that second vessel must also accept the UN numbers.
What Anxin does: We ask the carrier to name any transhipment port and the feeder operator on the booking and confirm DG acceptance for that leg as well as the mainline.
- Destination port
National Single Window declaration and the harbour master's conditions
In the ports supervised by the Maritime Office in Gdynia, the dangerous goods on an arriving ship are declared through the National Single Window at least 24 hours ahead, or on departure from the previous port on a short leg, which is common for Baltic feeders. The harbour master then gives consent and sets conditions for entry and handling.
What Anxin does: Because most Chinese cargo reaches Gdansk by feeder, we check the DG data are final before the mainline ship leaves Shanghai, so the feeder's declaration is not built on a draft.
- Import country
Safety documentation for stationary storage systems
Since 18 August 2024 a stationary battery energy storage system placed on the EU market must be safe in normal operation, and its technical documentation must show testing against the Annex V safety parameters, from thermal shock and short-circuit protection to over-discharge and thermal propagation. Buyers of ESS cabinets in Poland increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Poland we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.
- Import country
Built-in portable batteries must be user-replaceable from February 2027
From 18 February 2027, Article 11 requires portable batteries built into appliances to be readily removable and replaceable by the end-user with commercially available tools, without heat or solvents, apart from limited derogations. Appliances shipped to Poland for sale after that date need a design that meets the rule.
What Anxin does: When appliances with built-in batteries are booked for Poland we point the importer to the February 2027 date so the manufacturer answers the design question before shipment; we do not assess compliance.
Documents & compliance
Checklist for Shanghai → Gdansk
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.

Before you book
Send the file once, complete
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
Risks on this route and who deals with them
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Feeder operator does not accept the UN numbers | North Sea hub | DG acceptance for the feeder leg confirmed | Anxin with the carrier |
| Feeder's declaration differs from the mainline booking | Port of Gdansk | DG data final before the mainline departure | Carrier / agent |
| Storage system delivered without Annex V test file | Buyer in Poland | Test documentation confirmed before booking | Manufacturer |
Questions
Questions about shipping from Shanghai to Gdansk
The importer's: name, registered trade name or trade mark and postal address with a contact point, on the battery or, if it is too small, on the packaging or accompanying document.
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.
