Lithium batteries for Oxelosund go from factories around the Pearl River Delta through Yantian or Shekou. On the way they face a Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and they arrive at the port of Oxelosund.
The Swedish side adds the Naturvårdsverket register to the EU battery rules. 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
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
In the order the cargo meets them: at the loading port, at sea, at Oxelosund and at customs in Sweden.
Much of Shenzhen's battery cargo is made in Dongguan, home to more than 500 battery firms. In September 2026 Dongguan Customs and Dongguan MSA began sharing dangerous-goods packaging certificate data, described as a first in China, and committed to joint action against concealed and false declarations. The one-box route to Yantian, which had moved 409 containers by then, rests on that same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
Cargo for Oxelosund has to pass the Danish straits. IMO recommends pilots on Route T for ships of 11 m draught or more, and the Danish Maritime Authority reports ships that ignore the recommendation to their flag state. Whether the box stays on one vessel or is transhipped onto a feeder at a North Sea port, each vessel has to 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.
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.
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 Sweden for sale after that date need a design that meets the rule.
What Anxin does: When appliances with built-in batteries are booked for Sweden 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
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.

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 |
|---|---|---|---|
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | 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 |
| Producer not yet registered with Naturvårdsverket | Importer in Sweden | Registration confirmed before booking | Importer |
Questions
ADR, which the EU applies to domestic journeys through Directive 2008/68/EC. UN 3480 is class 9, transport category 2, with tunnel restriction code (E).
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.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.

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