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.

Yellow Sea · East China Sea · Taiwan Strait · South China Sea · Gulf of Tonkin
Lithium batteries for Hai Phong go out of Qingdao on the Yellow Sea, where April to July is fog season. On the way they face Southeast Asian waters, with their typhoon and monsoon seasons, and they arrive at the port of Hai Phong.
Vietnam adds an e-manifest and DG declaration due 12 hours before arrival on short voyages. 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
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.
For Vietnam, the DG declaration is due before arrival and consumer batteries need QCVN 101 conformity.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Hai Phong and at customs in Vietnam.
Shandong MSA has issued a waterway safe-transport guide specifically for lithium battery energy storage systems at Shandong coastal ports, so ESS units shipped from Qingdao should be prepared with that provincial guide in mind as well as the IMDG Code.
What Anxin does: For ESS cargo we review the unit's packing and securing plan against the Shandong guide with the packing site before booking.
The China Meteorological Administration describes sea fog as one of the major marine hazards of the Yellow and Bohai Seas, with the season mainly from April to July and a serious effect on sea transport. Fog holds at Qingdao can move a battery box to another vessel, and the DG filings have to move with it.
What Anxin does: In fog season we leave slack between stuffing and the DG cut-off at Qianwan and keep the cargo report ready to amend quickly if the vessel changes.
Western North Pacific typhoons average 25.1 a year (JMA, 1991-2020), with August and September the busiest months. For Hai Phong the risk is less the sea passage than a port closure in Qingdao 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.
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 Qingdao to Hai Phong, 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.
When Typhoon Yagi struck in September 2024, Hai Phong and Quang Ninh closed their ports from 6 September, and quay cranes collapsed at the MIPEC and Nam Dinh Vu terminals. A storm on this coast can stop work at Hai Phong for days and damage stacked containers.
What Anxin does: In the storm season we ask the consignee at Hai Phong to collect battery containers promptly after discharge rather than leave them stacked in the terminal.

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.

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 Qingdao 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 | Where | Mitigation | Who acts |
|---|---|---|---|
| Fog hold forces a vessel change after filing | Qingdao, Apr–Jul | Slack in schedule; amendment-ready filing | Anxin with the declarant |
| 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 |
| Port closure and yard damage in a typhoon | Northern Vietnam, Jul-Oct | Prompt collection after discharge | Consignee |
Questions
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.
Mainly April to July, according to the China Meteorological Administration, which calls sea fog a major hazard for Yellow Sea transport.
