Lithium batteries for Burgas go from the Pearl River Delta via Nansha. On the way they face a corridor through the Turkish Straits, and they arrive at the port of Burgas.
The Bulgaria side follows the EU battery and customs pre-filing rules. Below are 6 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 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.
Suez, the Aegean and the Turkish Straits, with a 24-hour DG sailing plan before the Bosporus and, since September 2026, almost the whole Black Sea on the war-risk list.


Where this route gets difficult
They run from the Guangzhou terminal through the voyage to Burgas and the Bulgaria import file.
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.
In September 2026 Dongguan Customs and Dongguan MSA started sharing dangerous-goods packaging certificate data, described as a first in China, together with joint action against concealed and false declarations; Huangpu Customs also runs a joint 'lithium batteries going overseas' service against misdeclaration. A packaging certificate that does not match the MSA filing is now visible to both agencies.
What Anxin does: We check that the UN number, packaging code and quantities on the packaging certificate are exactly those on the MSA cargo report before either is submitted.
On 16 September 2026 the Joint War Committee widened its Black Sea listed area to almost the entire sea, leaving out only Turkish, Georgian, Bulgarian and Romanian territorial waters. Ships entering must notify their war-risk underwriters, who may charge additional premiums per voyage, and carriers can pass that on.
What Anxin does: We ask the carrier for any war-risk surcharge to Burgas in writing before booking and recheck it if the sailing moves.
Since 18 August 2024 a battery sold in the EU needs the CE marking and an EU declaration of conformity from its manufacturer. The declaration has to be available in the language Bulgaria requires, and the importer is the one who must check both before the goods are released for sale.
What Anxin does: We ask the manufacturer in China for the declaration of conformity and a photo of the CE marking on the battery or its packaging before loading, and pass them to the Bulgaria importer. We check that the documents exist and match the goods; we do not assess conformity.
For Burgas, EU security pre-filing happens at the other end of the voyage: the ICS2 entry summary must reach the system 24 hours before the container is loaded in Guangzhou. No filing means no loading, and a missing EORI number is enough to reject it.
What Anxin does: We collect the consignee's EORI number, an HS-level goods description and the house-bill parties at booking, and make sure the party filing the ENS has them before the Guangzhou cut-off.
Regulation (EU) 2025/1561 pushed the Battery Regulation's due diligence duties for cobalt, lithium, nickel and natural graphite back to 18 August 2027 and gave the Commission until 26 July 2026 for its guidelines. Buyers in Bulgaria are already collecting the supply-chain information they will need.
What Anxin does: We pass the Bulgaria 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
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.

We line up UN numbers, model names and package counts across the Guangzhou filings, the booking with the carrier and the documents for Bulgaria before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Burgas.
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 closure after filings are made | Nansha, Jun–Oct | Slack in stuffing date; prompt refiling | Anxin with the declarant |
| Mismatch between packaging certificate and MSA filing flagged by shared data | Dongguan / Nansha | Line-by-line check before submission | Anxin with the declarant |
| Additional war-risk premium added after booking | Black Sea listed area | Surcharge confirmed in writing | Carrier, checked by Anxin |
| Declaration of conformity missing or not in the required language | Importer in Bulgaria | Declaration and CE photo collected before loading | Manufacturer / importer |
| ENS not filed and the box is refused at loading | Loading port, Guangzhou | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
Questions
24 hours before the container is loaded in China, not before it reaches Burgas. Without it carriers do not load the box, and a filing without an EORI number is rejected.
Possibly. Since 16 September 2026 almost the whole Black Sea, outside Turkish, Georgian, Bulgarian and Romanian territorial waters, is a Joint War Committee listed area, and underwriters may charge additional premiums. We get the carrier's surcharge in writing.
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.

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