Lithium batteries for Wallhamn go through Guangzhou's Nansha terminals, which since September 2026 accept Dongguan-inspected battery boxes without a second check. On the way they face a voyage that may run through Suez as drawn or round the Cape, depending on the service, and they arrive at the port of Wallhamn.
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.

Where this route gets difficult
What to watch between Guangzhou and Wallhamn: 5 points
Listed from loading in Guangzhou to import into Sweden, each with what we do about it.
- Origin port
Typhoon weeks at the Pearl River mouth
The Hong Kong Observatory puts the region's tropical cyclone season from June to October, busiest July to September. Nansha sits at the mouth of the Pearl River; a closed gate or a changed vessel means the DG filings and the packing certificate have to follow the box to a new sailing.
What Anxin does: From June to October we leave slack between stuffing and the DG cut-off at Nansha and refile quickly if the vessel changes.
- Sea corridor
Container losses off South Africa
Routing round Africa takes battery boxes past the Cape. The World Shipping Council counted 576 containers lost at sea in 2024, and the South African Maritime Safety Authority estimates around 200 of them, about 35%, were lost near the Cape; in August 2024 SAMSA reported 99 boxes lost from the CMA CGM Belem off Richards Bay and 46 from the MSC Antonio off Port St Johns in winter weather.
What Anxin does: When the booking goes via the Cape, we apply the CINS stuffing checks (gaps, blocking, wall clearance) more strictly and ask for photos at every stage of packing.
- Import country
Substance limits for portable batteries
For portable batteries, Annex I sets maximum levels of 0.0005 % mercury, 0.002 % cadmium and 0.01 % lead by weight, the lead limit applying since 18 August 2024. The importer in Sweden may be asked by market surveillance to demonstrate compliance.
What Anxin does: We ask the manufacturer for its substance declaration or test report reference and file it with the shipping documents for the Sweden importer; we do not test batteries.
- Import country
Naturvårdsverket registration since January 2026
Sweden's supplementary ordinance to the Battery Regulation (SFS 2025:813) has required battery producers to be registered with Naturvårdsverket since 1 January 2026. A producer responsibility organisation such as El-Kretsen can help with the filing, but the data remain the producer's responsibility.
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.
- 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 Sweden increasingly ask for that file before delivery.
What Anxin does: For ESS cabinets and racks bound for Sweden 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
What to have ready: Guangzhou to Wallhamn
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.
In Guangzhou, before the box is loaded
- 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
- Transport-condition classification report where applicable
Carrier and voyage
- Routing (Suez or Cape of Good Hope) and any transhipment port stated on the booking confirmation
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
- Consignee EORI and HS-level description to the ENS filer before loading
For the importer in Sweden
- Naturvårdsverket registration of the Swedish producer
- Label and QR-code status against the August 2026 and February 2027 dates
- Instructions and safety information in the language Sweden requires
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
Risks on this route and who deals with them
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| Heavy weather off South Africa | Cape of Good Hope | CINS stuffing and blocking checks before sealing | Packing site, checked by Anxin |
| Producer not yet registered with Naturvårdsverket | Importer in Sweden | Registration confirmed before booking | Importer |
| Storage system delivered without Annex V test file | Buyer in Sweden | Test documentation confirmed before booking | Manufacturer |
Questions
Common questions on the Guangzhou → Wallhamn route
24 hours before the container is loaded in China, not before it reaches Wallhamn. Without it carriers do not load the box, and a filing without an EORI number is rejected.
Ships of 5,000 GT and above calling at EU ports are in the EU Emissions Trading System, covering 50% of the emissions of a voyage from outside the EU. Lines must surrender allowances for 70% of 2025 emissions and 100% from 2027, and may pass the cost on as a surcharge.
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.
