Of castor seeds
Oil-cake and solid residues from extraction of castor seed oil
HSN 2306 90 17 (oil-cake and solid residues from the extraction of castor seed oil) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Oil-cakes and residues derived from other oilseeds — particularly groundnut and cottonseed — as well as prepared animal fodder formulations elsewhere in Chapter 23, may attract distinct compliance obligations.
Castor oil-cake contains residual ricin, a toxic alkaloid, and is commercially distinct from edible oil-cakes used in animal feed; the intended use stated on shipping documents must accurately reflect the product's composition and application. Re-classification by customs — for instance, into a prepared animal fodder heading — triggers retrospective compliance, including potential detention and duty recovery. Verify the product specification, ricin content where applicable, and end-use declaration before shipment.
