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 Saigon Port 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 Southeast Asian sea passage with no canal on the way, and they arrive at the port of Saigon Port.
In Vietnam the DG declaration reaches customs before the ship arrives and consumer batteries need QCVN 101 conformity. The 5 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.
A Southeast Asian sea route with no canal: typhoons from summer to autumn, the north-east monsoon from November to March, and relays through Singapore or other hubs for smaller ports.


Where this route gets difficult
They run from the Tianjin terminal through the voyage to Saigon Port and the Vietnam import file.
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.
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.
Routes from northern China to Saigon Port go through the Taiwan Strait, whose funnel effect makes winds 1-2 Beaufort levels stronger than outside. In winter and spring the north-east monsoon brings force 7 or more on about two-thirds of days, which is hard on a load that has not been braced.
What Anxin does: We ask for blocking and bracing photos before the container is closed in Tianjin, checked against the CINS stuffing guidance for lithium batteries.
Since 15 August 2025, Decree 167/2025 requires the e-manifest, bill of lading data and dangerous goods declaration to reach Vietnam Customs 12 hours before the ship arrives when the voyage is shorter than five days, or 24 hours before on longer voyages. From Tianjin the short limit usually applies, so the DG data must be final at booking.
What Anxin does: We send the carrier the full DG description with the booking, so the Vietnamese filing can go in on time without corrections.
Lithium batteries for mobile phones, tablets and laptops fall under Vietnam's QCVN 101. Before sale, the importer must register them for state quality inspection, test them and declare conformity, so a consignment for Saigon Port can wait in the port until that is done.
What Anxin does: For consumer batteries we ask the importer to start the QCVN 101 registration before the goods leave Tianjin, using test data from the manufacturer.

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 Tianjin filings, the booking with the carrier and the documents for Vietnam before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Saigon Port.
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 |
| Container held for a late or corrected DG declaration | Vietnamese port of discharge | DG data final at booking | Carrier, with data from Anxin |
Questions
Producers and importers, who must recycle or contribute to the Vietnam Environment Protection Fund under Decree 05/2025.
It waits or moves to the next vessel. The dangerous goods declaration has to be refiled for that vessel, which is why we check DG acceptance for a back-up sailing in typhoon months.
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.
