From Xiamen to Chennai, cargo moves out of Xiamen's Haicang and Songyu terminals on the Taiwan Strait, crosses a corridor across the Indian Ocean, and is discharged at the port of Chennai.
In India the BIS R-number must match the manufacturer, model and factory on crsbis.in. Below are 5 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
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.
An Indian Ocean route: rough south-west monsoon seas from June to September and cyclone windows in April-May and October-December.


Where this route gets difficult
Listed from loading in Xiamen to import into India, each with what we do about it.
Xiamen MSA offers pre-review of key DG documents, a pre-loading meeting at which ship, cargo owner, terminal and agent agree deck stowage and emergency measures, and a 'one ship, one plan' checklist from gate-in to sailing. In June 2026 it reported 104 energy-storage containers of 36 tonnes each loaded for Houston on a multipurpose ship.
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.
Xiamen Customs now issues the packaging use-appraisal certificate for lithium batteries through the single window after automatic pre-review matching: about 10 minutes in the case reported in August 2026, against roughly half a day for the old on-site inspection. The fast path is only for products that pass pre-review as compliant and valid; anything that does not match goes back to inspection.
What Anxin does: We check the product data, UN38.3 summary and packaging codes against the application before it is submitted, so the certificate comes through pre-review rather than falling back to an on-site check.
Colombo is the main transhipment hub for Indian cargo: 8.29 million TEU in 2025, about 81% transhipment, around 45% of it India-linked. For Chennai, a relay there means a second vessel whose DG acceptance matters as much as the first.
What Anxin does: We ask the carrier at booking whether the service to Chennai relays in Colombo or elsewhere, and check that the DG acceptance covers the feeder leg too.
The India Meteorological Department describes October to December as Tamil Nadu's main rainy season, with onset around 20 October and nearly half the state's annual rainfall. Heavy rain at Chennai slows cargo work and inland trucking.
What Anxin does: For arrivals at Chennai in the north-east monsoon we tell the consignee to expect rain delays and keep documents filed early.
India requires lithium-ion cells and batteries to be registered under BIS's CRS (IS 16046 Part 2) before import. The registration number is declared in the Bill of Entry, so a missing or wrong number stops the container at Chennai.
What Anxin does: Before booking we ask for the manufacturer's BIS R-number and check that it covers the models and factory named in the shipment.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; 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 India 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 |
|---|---|---|---|
| Application fails pre-review and falls back to on-site inspection | Xiamen Customs | Data checked against the application first | Anxin with the manufacturer |
Questions
They verify the registration on crsbis.in, including manufacturer, model and factory location, and refuse deferred or cancelled registrations.
Often, yes. Colombo is the main relay for Indian cargo, so we ask the carrier where the service relays and check that the feeder accepts the batteries too.
For products that pass automatic pre-review, Xiamen Customs issues it through the single window; the case reported in August 2026 took about 10 minutes, against about half a day for the old on-site inspection. Products that do not pass pre-review still need inspection.
