Courier export eligibility limited by excluded categories; higher-value consignments allowed under courier regulations and notified instruments. Exports by courier are generally permitted but exclude goods attracting export duty, exports under export promotion schemes, and consignments exceeding the domestic value threshold when foreign exchange is involved unless a central bank waiver or specific permission is obtained. Courier regulations and notified customs instruments authorise export of cargo through courier up to the prescribed FOB limit per consignment; compliance with the stated monetary ceiling, exclusions, and any required permissions is mandatory.
