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 Sundsvall, 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 Sundsvall.
Sweden has required producer registration with Naturvårdsverket since January 2026. 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
- Dongguan–Nansha one-box
- Typhoon season Jun–Oct
- Swedish-language safety information
- Consignee EORI
- EU declaration of conformity

Listed from loading in Guangzhou to import into Sweden, each with what we do about it.
- Origin port
Nansha MSA's state-of-charge advice for energy storage
At a July 2024 meeting on energy-storage carriage, Nansha MSA recommended shipping ESS batteries at a state of charge of around 25% and preventing accidental activation. It is a recommendation rather than a fixed rule, but it is the figure the local authority has put on record.
What Anxin does: For ESS cargo leaving Nansha we ask the manufacturer to state the shipping state of charge and the anti-activation measures in writing, and put both in the documents the carrier sees.
- Sea corridor
EU emissions trading now covers the whole inbound voyage share
Ships of 5,000 GT and above calling at EU ports, Sundsvall included, are in the EU Emissions Trading System: 50% of the emissions of a voyage from China are covered, and the share of emissions for which lines must surrender allowances rises from 70% (for 2025 emissions) to 100% from 2027. Carriers can pass that cost on 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.
- Import country
The truck leg out of Sundsvall runs under ADR
Road delivery from Sundsvall is an ADR movement, because the EU applies ADR to domestic journeys through Directive 2008/68/EC. For UN 3480 that means class 9, transport category 2 and tunnel code (E), which restricts the route through category E tunnels; batteries found damaged at unloading move to special provision 376 packing (P908 or P911).
What Anxin does: We give the Sweden haulier the same UN number, class and package details that appear on the sea dangerous goods declaration, so the ADR transport document matches the container paperwork from Guangzhou.
- Import country
Safety information in a language Sweden accepts
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.
- Import country
Battery label from August 2026, QR code from February 2027
Two marking dates fall into current shipping plans for Sweden: 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 Sweden 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
Documents to line up for Guangzhou → Sundsvall
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.
Before loading in Guangzhou
- For ESS: written shipping state of charge and anti-activation measures from the manufacturer
- 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
- Transport-condition classification report where applicable
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
Carrier and 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)
For the importer in Sweden
- Label and QR-code status against the August 2026 and February 2027 dates
- Naturvårdsverket registration of the Swedish producer
- Haulier in Sweden briefed with UN number, class 9 and tunnel code (E) for the road leg
Before you book
One consistent file
A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Guangzhou export filings, the carrier booking and the Sweden import papers. We compare all three before confirming space.
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
What could go wrong from Guangzhou to Sundsvall, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Emissions surcharge changes between quote and sailing | EU port call | Surcharge shown as a separate line | Carrier, checked by Anxin |
| Stock shipped without the label due from August 2026 | Importer in Sweden | Label status confirmed before booking | Manufacturer / importer |
| Road route planned through a category E tunnel | Road leg from Sundsvall | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
Questions about shipping from Guangzhou to Sundsvall
Yes. Since 1 January 2026 producers, which includes importers placing batteries on the Swedish market, must be registered with Naturvårdsverket under Ordinance 2025:813.
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.
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.
