Bohai Sea · Bohai Strait · Taiwan Strait · Malacca Strait · Indian Ocean · Bab-el-Mandeb · Suez Canal · Bosporus
This route runs through Tianjin, with its Beijiang and Dongjiang terminals on the Bohai Bay, then follows a corridor through the Turkish Straits; at the far end is the port of Constanta.
The Romania 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
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.
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
Listed from loading in Tianjin to import into Romania, each with what we do about it.
Sea ice forms every winter in the Bohai Sea, and the Haihe estuary at Tianjin is among the severe areas. In winter 2021/22 China's national marine forecast centre expected the peak ice period from mid-January to mid-February, with floating ice reaching about 5 nautical miles out in Bohai Bay. Ice and cold spells slow port operations around the Chinese New Year shipping peak.
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.
Tianjin Customs runs a 'supervised factory loading, direct loading on port arrival' model for dangerous goods: officers oversee stuffing at the factory, the declaration goes in early through the single window, and the container enters the port in a slot booked on the customs–port platform and goes straight to the ship. Any inspection happens in closed yards inside the Beijiang and Dongjiang terminals. The time saved depends on the stuffing date, the slot and the declared data all matching.
What Anxin does: We fix the stuffing date against the vessel's DG cut-off first, then book the entry slot, and check that the declaration, the packing certificate and the container number agree before the truck leaves, so the box is not diverted to an inspection yard for a data mismatch.
Ships carrying dangerous cargo must file a Sailing Plan 1 with the Turkish Straits VTS at least 24 hours before entering the straits, declaring the dangerous goods classes on board. A class 9 battery container is part of that declaration, so late or wrong DG data on the manifest can hold the ship up at the entrance.
What Anxin does: We make sure the DG manifest data (UN number, class, quantity, container number) are final and match the booking before the vessel leaves the last port before the straits.
The importer in Romania carries the check: CE marking on the battery and an EU declaration of conformity, translated into the language Romania asks for, have both been required since 18 August 2024 for batteries entering the EU market.
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 Romania importer. We check that the documents exist and match the goods; we do not assess conformity.
Road delivery from Constanta 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 Romania 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.
Importers must make sure batteries come with instructions and safety information in a language end-users in Romania easily understand, as that Member State decides. Printed inserts and carton text are far easier to change before the goods are packed in China.
What Anxin does: We ask the importer which language Romania requires and check carton and insert photos against it before loading.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.

We line up UN numbers, model names and package counts across the Tianjin filings, the booking with the carrier and the documents for Romania before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Constanta.
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 |
|---|---|---|---|
| Box sent to the terminal inspection yard because declared data do not match | Beijiang / Dongjiang terminals | Declaration, packing certificate and container number cross-checked before trucking | Anxin |
| 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 |
| Incorrect DG data in the straits sailing plan | Turkish Straits | Manifest checked against the booking | Carrier, with data from Anxin |
| Declaration of conformity missing or not in the required language | Importer in Romania | Declaration and CE photo collected before loading | Manufacturer / importer |
| Road route planned through a category E tunnel | Road leg from Constanta | Tunnel code (E) passed to the haulier with the transport data | Haulier / forwarder |
Questions
The importer's: name, registered trade name or trade mark and postal address with a contact point, on the battery or, if it is too small, on the packaging or accompanying document.
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.
