Xiamen (Haicang / Songyu)
Fujian's battery gateway, handling more than 90% of the province's lithium battery exports, with 10-minute online packaging appraisal for compliant products and the Taiwan Strait's winter monsoon on the doorstep.
South & Southeast Asia · sea freight from Xiamen
Xiamen to Colombo
South China Sea · Malacca Strait · Andaman Sea · Indian Ocean
Lithium batteries for Colombo go from Fujian's battery makers through Xiamen port. On the way they face an Indian Ocean passage after the Malacca Strait, and they arrive at the port of Colombo.
Sri Lanka adds manifests through ASYHUB and fully electronic customs declarations from October 2026. 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
Fujian's battery gateway, handling more than 90% of the province's lithium battery exports, with 10-minute online packaging appraisal for compliant products and the Taiwan Strait's winter monsoon on the doorstep.
After the Malacca Strait comes the Indian Ocean, where the south-west monsoon and two cyclone seasons decide the pace.


Where this route gets difficult
Loading port first, then the sea leg, then Colombo and the Sri Lanka market.
For large battery consignments Xiamen MSA offers pre-review of key DG documents, a pre-loading meeting where ship, cargo owner, terminal and agent agree deck stowage and emergency measures, and a 'one ship, one plan' checklist from gate-in to departure. In June 2026 it reported 104 energy-storage containers of 36 tonnes each loaded on a multipurpose ship for Houston.
What Anxin does: We send the key documents for pre-review before the formal filing and bring the stowage and emergency details the meeting will ask for.
Leaving Xiamen, ships are in the Taiwan Strait at once. A Chinese government weather account says the strait's funnel effect adds 1–2 Beaufort levels to the wind, and that the north-east monsoon of winter and spring brings force 7 or more on about two days in three. Lashing on container ships should be secured accordingly.
What Anxin does: From October to April we apply the CINS blocking and bracing checks strictly on stuffing photos before sealing.
ReCAAP counted 21 armed-robbery incidents in the Straits of Malacca and Singapore in the first half of 2026, down 74% but still 60% of all Asian cases. They are mostly night-time thefts of engine spares from bulk carriers and barges; a container ship bound for Colombo is a less usual target but uses the same lanes.
What Anxin does: We keep the vessel and voyage on the booking record for Colombo, so a carrier incident or delay notice can be matched to the shipment straight away.
SLSI's compulsory inspection list covers primary cells (HS 8506.10 and 8506.80) and lead-acid starter batteries, but not lithium-ion batteries under 8507.60. The HS code on the documents for Colombo therefore decides whether an SLSI inspection is needed, especially for mixed shipments.
What Anxin does: We check the HS codes on the invoice with the importer, and flag any primary cells in the shipment that would bring SLSI inspection.
Since 7 May 2025 Sri Lanka Customs has required manifests to be submitted through ASYHUB. The battery description and DG details the carrier files for Colombo come from the booking made in Xiamen, so they have to be right from the start.
What Anxin does: We give the carrier final cargo and DG data at booking, so the ASYHUB manifest does not need amending after arrival.

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.

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 Xiamen filings, the carrier booking and the Sri Lanka 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 |
|---|---|---|---|
| Cargo shift in winter monsoon seas | Taiwan Strait, Oct–Apr | CINS blocking and bracing checked on photos | Packing site, checked by Anxin |
Questions
No. From 1 October 2026 CusDecs are digitally signed and electronic.
The India Meteorological Department describes two North Indian Ocean seasons, April–May and October–December, the latter being the main one.
Yes. Xiamen MSA reported 104 ESS containers of 36 tonnes each loaded for Houston in June 2026. Xiamen's ESS guide 2.0 requires a pre-voyage meeting and use of a class 9 qualified terminal.
