Oleic acid
Industrial oleic acid from rubber seed fatty acids
HSN 3823 12 00 (Oleic acid) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 12124:1987 is mandatory under the ISI Mark Scheme with effect from 28 October 2022, by virtue of the Rubberseed Fatty Acids (Quality Control) Order, 2022. No separate customs-clearance overlay beyond the BIS QCO obligation applies to this tariff line.
- 1Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 12124:1987 for rubberseed fatty acids. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility address on the BIS online register before placing the purchase order.Rubberseed Fatty Acids (Quality Control) Order, 2022 · S.O. 1966(E) dated 27-04-2022
- 2Ensure the goods bear the ISI standard mark and the supplier's CM/L number under licence per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. The mark must appear on the product or its primary container, not packaging alone.Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 · Rubberseed Fatty Acids (Quality Control) Order, 2022
- 3Retain the supplier's conformity documentation — test reports against IS 12124:1987 and the CM/L licence certificate — as part of the import record. Customs may demand production of these documents at the port of entry.IS 12124:1987 · BIS Act, 2016 · General Note 2 of the ITC (HS) Import Policy
- 4Quote the supplier's BIS CM/L number on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or product-scope-mismatched licence triggers consignment detention, demurrage, and potential re-export or confiscation.Rubberseed Fatty Acids (Quality Control) Order, 2022 · BIS Act, 2016 · Customs Act, 1962
The single most common error on this tariff line is assuming that IS 12124:1987 — titled in earlier practice against stearic acid — does not extend to oleic acid imported under HSN 3823 12 00. The Rubberseed Fatty Acids (Quality Control) Order, 2022 expressly maps IS 12124:1987 to this tariff item; importers who rely on the standard's legacy stearic-acid association and omit CM/L verification face detention at port regardless of the chemical purity of the consignment. Confirm the supplier's CM/L licence scope covers oleic acid specifically before shipment.
