Of castor seeds
Oil-cake and solid residues from castor seed extraction
HSN 2306 90 27 (oil-cake and other solid residues from the extraction of castor seed fats or oils) 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 (IEC), bill of entry, commercial invoice, packing list. Oil-cakes derived from other oilseeds — or residues further processed into prepared animal feed — may fall under sibling tariff lines within Chapter 23 that carry distinct compliance requirements.
Castor oil-cake is toxic to livestock and humans due to ricin content, which can prompt customs examination scrutiny even in the absence of a formal pre-import licence requirement; any misdescription of intended use or processing state risks detention pending re-classification. Residues presented as or blended into prepared animal fodder may attract compliance under a different Chapter 23 heading. Confirm the product's ricin-deactivation status, physical form, and intended end-use before import to ensure classification accuracy.
