From Shenzhen to Trelleborg, cargo moves out of Shenzhen's Yantian and Shekou terminals, crosses a long Europe voyage extended through the Danish straits into the Baltic, and is discharged at the port of Trelleborg.
The Swedish side adds the Naturvårdsverket register to the EU battery rules. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
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.
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.


Where this route gets difficult
They run from the Shenzhen terminal through the voyage to Trelleborg and the Sweden import file.
The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
Much Shenzhen battery export is stuffed inland and trucked to the terminal. In May 2026 Yantian MSA and Dongguan MSA ran a cross-regional 'one-box' pilot: four battery containers were inspected jointly at the Dongguan factory and loaded at Yantian without being opened again. It shows that the inspection record made at the factory is what matters at the terminal.
What Anxin does: We ask at booking whether your factory and the terminal's MSA office can use the one-box arrangement, and we have stuffing photos, the packing certificate and the DG declaration match exactly, so the container is not held for re-inspection.
Up to the Danish straits the voyage matches North Europe's: Sea-Intelligence put Red Sea routing at 27% for North Europe services in September 2026, so most containers still sail round the Cape of Good Hope, where SAMSA estimates about 35% of the containers lost in 2024 went overboard.
What Anxin does: We quote the Suez and Cape routings separately when both are offered and apply the CINS stuffing checks strictly on Cape sailings.
Since 1 January 2026 battery producers in Sweden must be registered with Naturvårdsverket under the supplementary ordinance SFS 2025:813. Producer responsibility organisations such as El-Kretsen can assist with the filing, though the producer stays responsible for the data.
What Anxin does: We ask the Swedish importer to confirm the registration is in place before booking, and pass on battery chemistry and weight data it may need for reporting.
An importer has to ensure that batteries are accompanied by instructions and safety information in a language that end-users in Sweden can easily understand, as the Member State determines. Inserts and carton print are much simpler to adjust before packing in China.
What Anxin does: We ask the importer which language Sweden requires and check carton and insert photos against it before loading.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; 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 Sweden 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 |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Container reopened at the terminal because records do not match | Factory → Yantian | Photos, packing certificate and DG declaration cross-checked before trucking | Anxin |
| Producer not yet registered with Naturvårdsverket | Importer in Sweden | Registration confirmed before booking | Importer |
Questions
The CE marking on the battery and the manufacturer's EU declaration of conformity, which must be available in the language Sweden requires. Both have applied since 18 August 2024.
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.
Yes, provided a certified packing inspector supervises the stuffing and signs the container packing certificate. Since May 2026 Yantian and Dongguan MSA have also piloted joint factory inspection so the container can be loaded at Yantian without reopening; we check whether your shipment can use it.

We check carrier acceptance for Shenzhen → Trelleborg before any booking, and ask for missing battery documents first.
