Castor Seeds

Graded on oil yield and ricinoleic acid content

CBIL brokers castor seed from Gujarat and Rajasthan — the belt that supplies the large majority of world castor — graded on the two variables that decide a crusher's economics: oil content at 45–50% and ricinoleic acid at roughly 85–90% of that oil. Ricinoleic acid is why castor exists as a commodity at all. It is the hydroxylated fatty acid that no other commercial oil seed delivers at volume, and it is what makes castor the feedstock for sebacic acid, 12-hydroxystearic acid, polyamide 11, lubricants, coatings and a long list of derivatives, none of which can substitute another oil without redesigning the chemistry. That is the distinction from every other seed in this family: mustard, flax and niger compete with one another on price per tonne of oil; castor does not compete with anything.

This is an industrial line, not a food line, and it needs handling as one. Castor seed contains ricin in the meal fraction, so the seed and cake are subject to their own transport, storage and documentation requirements, and the de-oiled cake is not a feed ingredient without proper detoxification — buyers who assume otherwise get an expensive surprise. We supply against ≤ 6% moisture, ≤ 1% FFA on the extracted oil and ≤ 2% admixture, machine-cleaned and gravity-separated, with SGS or Intertek certification of oil content, ricinoleic acid, moisture, FFA and admixture plus phytosanitary and fumigation documentation. Supply is structured in 25kg and 50kg PP or jute bags, container-load, on FOB, CFR and CIF terms.
