Asia – Southeast Asian seas
Typhoons and the winter monsoon set the pace on this short Southeast Asian route; smaller ports are often reached through a hub.

From Tianjin to Cat Lai, cargo moves through Tianjin, with its Beijiang and Dongjiang terminals on the Bohai Bay, crosses a Southeast Asian sea passage with no canal on the way, and is discharged at the port of Cat Lai.
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
- Factory-supervised loading
- Bohai Bay winter ice
- 12-hour e-manifest
- QCVN 101
- Battery EPR

Where this route gets difficult
5 points to plan for on the Tianjin → Cat Lai route
They run from the Tianjin terminal through the voyage to Cat Lai and the Vietnam import file.
- Origin port
A slow document review at Tianjin can mean a missed vessel
Tianjin MSA itself said in July 2026 that, under the traditional review model, long document reviews often made firms miss the vessel's document cut-off, leaving cargo in port to be re-allocated to another ship. Its new fast-track green channel (appointment-based, more than 50% faster, with a fixed document list) is for new-energy-vehicle cargo; battery shipments should not assume they qualify.
What Anxin does: We submit the cargo report with the full document set (safe-carriage declaration, SDS, packing certificate, packaging certificate) days before the cut-off rather than on the day, and treat any MSA query as same-day work.
- Origin port
Tianjin's supervised factory loading and port slots
Under Tianjin Customs' 'supervised factory loading, direct loading on port arrival' model, officers supervise stuffing at the factory, the declaration is lodged early through the single window, and the box enters the port in a slot booked on the customs–port platform before going straight to the ship; inspections take place in closed yards at the Beijiang and Dongjiang terminals. The gain holds only if stuffing date, slot and declared data agree.
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 corridor
Typhoons close ports on both ends of the route
Western North Pacific typhoons average 25.1 a year (JMA, 1991-2020), with August and September the busiest months. For Cat Lai the risk is less the sea passage than a port closure in Tianjin or on arrival, which moves the box and its DG declaration to a later ship.
What Anxin does: In typhoon months we check the carrier's DG acceptance for the next two vessels as well, so a rolled container can be refiled quickly rather than rebooked from scratch.
- Import country
QCVN 101: quality inspection before consumer batteries are sold
Vietnam checks lithium batteries for phones, tablets and laptops against QCVN 101: inspection registration, testing and a declaration of conformity are needed before sale. Importers receiving them at Cat Lai should start early.
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.
- Import country
Decree 167: DG data to customs before the ship reaches Cat Lai
Vietnam now wants the manifest, B/L data and DG declaration 12 hours before arrival for short voyages and 24 hours for longer ones (Decree 08/2015 as amended in 2025). For a container from Tianjin to Cat Lai, errors found after that point hold the box.
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.
Documents & compliance
What to have ready: Tianjin to Cat Lai
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.
In Tianjin, before the box is loaded
- Stuffing date, port-entry slot and DG cut-off at Tianjin agreed in that order
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
- Blocking and bracing photos for monsoon-season sailings
- 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)
Carrier and voyage
- DG acceptance confirmed for a back-up vessel in typhoon months
- 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 Vietnam
- QCVN 101 registration started for phone, tablet or laptop batteries
- Importer's EPR registration for battery volumes
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 Tianjin export filings, the carrier booking and the Vietnam 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 Tianjin → Cat Lai
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Document review runs past the vessel cut-off; cargo re-allocated to a later ship | Tianjin MSA review | Complete document set filed days before cut-off | Anxin with the declarant |
| 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 |
| Typhoon closes a port; the box moves to a later vessel | Southeast Asian ports, Jul-Oct | Back-up vessel with DG acceptance; prompt refiling | Anxin with the carrier |
| Container held for a late or corrected DG declaration | Vietnamese port of discharge | DG data final at booking | Carrier, with data from Anxin |
Questions
Questions about shipping from Tianjin to Cat Lai
They fall under QCVN 101: quality-inspection registration, testing and a declaration of conformity before sale.
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.
The green channel Tianjin MSA announced in July 2026 is for new-energy-vehicle cargo. For battery containers we plan on the normal review and file early, because Tianjin MSA has said long reviews under the traditional model often cost firms their vessel cut-off.
