Tianjin (Xingang)
North China's main container gateway, where Tianjin Customs lets DG containers be inspected at the factory and loaded on arrival within a booked port slot, and where the Bohai Bay freezes at its edges in mid-winter.

Lithium batteries for Varna go out of Tianjin's Xingang terminals, where customs can supervise stuffing at the factory and the box goes straight to the ship on a booked slot. On the way they face a corridor through the Turkish Straits, and they arrive at the port of Varna.
Bulgaria applies the EU Battery Regulation, starting with registration in its own national producer register. The 6 points below are particular to this lane; each comes with what we do and the paperwork it touches.
What we need to start
Route profile
North China's main container gateway, where Tianjin Customs lets DG containers be inspected at the factory and loaded on arrival within a booked port slot, and where the Bohai Bay freezes at its edges in mid-winter.
The EU Battery Regulation's national registration, CE marking and label duties, and the ICS2 entry summary before loading.


Where this route gets difficult
Loading port first, then the sea leg, then Varna and the Bulgaria market.
China requires use appraisal of export dangerous-goods packaging before the goods may be exported. Tianjin port's 2025 facilitation measures shortened packaging appraisal time for lithium battery exports through quick release, and Tianjin Port Group provides port services for lithium DG containers, but the appraisal certificate is still a precondition for the rest of the filing.
What Anxin does: We check at quotation that the packaging maker has its performance appraisal and apply for the use appraisal as soon as the packing is fixed, so the certificate is in hand before the MSA filing.
Every winter the Bohai Sea ices over, and the Haihe estuary at Tianjin is one of the harder-hit areas. For 2021/22 the national marine forecast centre put the peak ice period between mid-January and mid-February, with floating ice about 5 nautical miles out in Bohai Bay. Ice and cold slow port work just as the Chinese New Year peak arrives.
What Anxin does: For January and February sailings from Tianjin we add slack between stuffing and the DG cut-off and confirm the vessel's berthing window with the carrier the week before loading.
The Black Sea is reached through Suez. Mediterranean-type services used the Red Sea routing 57% of the time in September 2026, and the JMIC rated Bab el-Mandeb SUBSTANTIAL, with the Houthis holding Perim Island in the channel.
What Anxin does: We ask the carrier which routing the service uses and name it on the quote.
For Varna, 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 Tianjin. 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 Tianjin cut-off.
Once the container leaves the terminal by road, ADR applies: Directive 2008/68/EC makes EU countries use it for domestic dangerous goods journeys as well as international ones. UN 3480 is class 9, transport category 2, with tunnel restriction code (E), so the haulier in Bulgaria has to plan around category E tunnels, and damaged or defective batteries fall under special provision 376 and packing instructions P908 or P911 instead of P903.
What Anxin does: We give the Bulgaria 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 Tianjin.
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
Anxin reviews documents supplied by the shipper, manufacturer and importer; 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 Tianjin filings, the carrier booking and the Bulgaria 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 |
|---|---|---|---|
| Ice or cold spell slows berthing in mid-winter | Bohai Bay, Jan–Feb | Slack between stuffing and cut-off; berthing window reconfirmed | Carrier, monitored by Anxin |
| ENS not filed and the box is refused at loading | Loading port, Tianjin | EORI and house-bill data passed to the filer at booking | Filer (carrier / forwarder) |
| Road route planned through a category E tunnel | Road leg from Varna | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
No. Under the Battery Regulation producers register in each Member State where they first make batteries available, and the authority has up to 12 weeks to grant a complete application. A producer without an establishment in Bulgaria needs an authorised representative there.
A Sailing Plan 1 to the Turkish Straits VTS at least 24 hours before entry, including the dangerous cargo classes on board.
Tianjin Customs offers a 'supervised factory loading, direct loading on port arrival' model: stuffing is supervised at the factory, the box enters the port in a booked slot and is loaded directly. Whether a given shipment can use it depends on the customs arrangement for the exporter and the port slot; we check both when you book.
