CSB-IV, plainly: what it is and when you need it
The courier shipping bill most Indian ecommerce exports travel on — what it covers, the limits that apply, and the paperwork that has to match.
CSB-IV is the courier shipping bill used for low-value exports leaving India through an authorised courier. If you are an ecommerce seller posting orders to customers abroad, this is almost certainly the route your parcels take.
What it covers
- Consignments up to Rs 5,00,000 in declared value.
- Goods moving through a courier terminal rather than a full cargo shed.
- Exports where you are not claiming certain incentive schemes that require a full shipping bill.
CSB-IV is a customs document, not a shipping label. It stands or falls on whether the declared value, HSN code and description match what is in the box.
Where it goes wrong
Three failures account for most held consignments. An HSN code that does not exist or does not describe the goods. A declared value chosen to reduce duty rather than to be accurate. And a shipper name that does not match the registered account holder — the single fastest way to attract scrutiny.
The portal blocks the first at order creation: an HSN code has to be eight digits and has to exist in the master list before the order can leave draft. The third is checked at the settings level, comparing account holder, pickup contact and billing entity, and warns until they reconcile.
What you need in place
- An Importer Exporter Code (IEC) for commercial exports.
- GST registration where your turnover requires it.
- A commercial invoice whose line items match the declared contents exactly.
- Correct HSN classification per line item, not one code for the whole parcel.
