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.

From Guangzhou to Naantali, cargo moves out of Nansha, at the mouth of the Pearl River, crosses a long Europe voyage extended through the Danish straits into the Baltic, and is discharged at the port of Naantali.
Finland keeps its battery producers in a national register at the Finnish Supervisory Agency. 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
- Typhoon season Jun–Oct
- Nansha export
- Consignee EORI
- EU declaration of conformity
- Finnish producer register entry
Route profile
The Guangzhou → Naantali route in brief
Finland
Registration in the Finnish Supervisory Agency's producer register, a Finnish authorised representative for distance sellers, and EU importer duties such as CE marking and the importer's details on the battery.
Where this route gets difficult
What to watch between Guangzhou and Naantali: 5 points
They run from the Guangzhou terminal through the voyage to Naantali and the Finland import file.
- Origin port
Packaging certificate data now shared in Dongguan
Dongguan Customs and Dongguan MSA began sharing dangerous-goods packaging certificate data in September 2026, which they called a first in China, and agreed joint action on concealed and false declarations; Huangpu Customs runs a joint 'lithium batteries going overseas' service against misdeclaration as well. A mismatch between packaging certificate and MSA filing is visible to both.
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
The Danish straits and a possible feeder change
Every box for Naantali 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.
- Import country
Mercury, cadmium and lead limits in portable batteries
Annex I of the Battery Regulation caps mercury at 0.0005 %, cadmium at 0.002 % and lead at 0.01 % by weight in portable batteries, and the lead limit has applied since 18 August 2024. Market surveillance in Finland can ask the importer to show that the goods meet these limits.
What Anxin does: We ask the manufacturer for its substance declaration or test report reference and file it with the shipping documents for the Finland importer; we do not test batteries.
- Import country
Finnish producer register and a local representative for distance sellers
Producer responsibility for batteries in Finland runs through the national producer register, now held by the Finnish Supervisory Agency. A seller abroad that ships directly to Finnish customers must appoint an authorised representative established in Finland, and a producer organisation can take that role.
What Anxin does: We ask whether the Finnish consignee or a foreign seller is the producer of record, and for the register details, before booking.
- 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 Finland increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Finland we ask the manufacturer to confirm that the Annex V test documentation exists before booking and note the answer in the shipment file.
Documents & compliance
Documents to line up for Guangzhou → Naantali
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 loading in Guangzhou

- Substance declaration covering mercury, cadmium and lead limits
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
For the carrier and the voyage
- Transhipment port, feeder operator and feeder DG acceptance named on the booking
- UN 38.3 test summary for every cell and battery type
- Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)

- Haulier in Finland briefed with UN number, class 9 and tunnel code (E) for the road leg
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 Guangzhou filings, the carrier booking and the Finland 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 |
|---|---|---|---|
| Mismatch between packaging certificate and MSA filing flagged by shared data | Dongguan / Nansha | Line-by-line check before submission | Anxin with the declarant |
| Feeder operator does not accept the UN numbers | North Sea hub | DG acceptance for the feeder leg confirmed | Anxin with the carrier |
| Distance seller with no Finnish authorised representative | Finnish producer register | Producer role confirmed at booking | Seller / importer |
| Storage system delivered without Annex V test file | Buyer in Finland | Test documentation confirmed before booking | Manufacturer |
Questions
Questions about shipping from Guangzhou to Naantali
24 hours before the container is loaded in China, not before it reaches Naantali. Without it carriers do not load the box, and a filing without an EORI number is rejected.
Yes, but in the restriction period only ships of the required ice class and deadweight receive icebreaker assistance. Finland's agency publishes the restrictions on baltice.org, with exemption requests due at least three working days before arrival.
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.
