Guangzhou (Nansha)
Pearl River Delta battery cargo through Nansha, where a September 2026 agreement lets Dongguan-inspected containers load without a second MSA check, and where typhoon season runs June to October.

Lithium batteries for Oulu 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 Suez-or-Cape voyage that ends with the Danish straits and the Baltic, and they arrive at the port of Oulu.
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
- EU declaration of conformity
- Finnish producer register entry
- Finnish and Swedish safety information
Route profile
How Guangzhou → Oulu differs from other lanes
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.
Where this route gets difficult
5 pain points from Guangzhou to Oulu
Loading port first, then the sea leg, then Oulu and the Finland market.
- 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.
- Origin port
A recommended 25% charge for ESS from Nansha
Nansha MSA told a July 2024 meeting on energy-storage carriage that ESS batteries should travel at roughly 25% state of charge, with accidental activation prevented. It is advice, not a binding rule, yet it is the number the local authority has put on the 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
Ice-class restrictions in the northern Baltic
Every winter Finland's Transport Infrastructure Agency sets traffic restrictions for its ports: only ships of a stated ice class and deadweight get icebreaker assistance. Exemption requests must be in at least three working days before arrival, and the restrictions for the Baltic are published on baltice.org. A feeder without the right ice class may not be allowed to call at Oulu in the restriction period.
What Anxin does: For winter shipments we check the restrictions in force on baltice.org for Oulu and ask the carrier to confirm that the final feeder has the required ice class before we book.
- Import country
Safety information in a language Finland accepts
An importer has to ensure that batteries are accompanied by instructions and safety information in a language that end-users in Finland 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 Finland requires and check carton and insert photos against it before loading.
- Import country
Supply-chain due diligence moved to August 2027
The Battery Regulation's due diligence obligations on cobalt, lithium, nickel and natural graphite were postponed by Regulation (EU) 2025/1561 and now apply from 18 August 2027, with Commission guidelines due by 26 July 2026. Buyers in Finland are already asking suppliers for the supply-chain data they will need.
What Anxin does: We pass the Finland buyer's due diligence questions to the manufacturer and keep their answers with the shipment file; the policy itself remains the producer's responsibility.
Documents & compliance
Documents to line up for Guangzhou → Oulu
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
- For ESS: written shipping state of charge and anti-activation measures from the manufacturer
- 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 shipping line
- 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 Finland
- Instructions and safety information in the language Finland requires
- Haulier in Finland briefed with UN number, class 9 and tunnel code (E) for the road leg
- Finnish producer register entry (or authorised representative)
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 Finland 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
Risk table for Guangzhou → Oulu
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| Feeder lacks the ice class required under winter restrictions | Northern Baltic, winter | Ice class confirmed at booking | Carrier, checked by Anxin |
Questions
Common questions on the Guangzhou → Oulu route
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.
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.
