Gilsonete
Gilsonite, a natural solid bituminous hydrocarbon
HSN 2714 90 30 (Gilsonite) 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. Other bituminous substances within Chapter 27 — including petroleum bitumen, bituminous mixtures, and bituminous or oil shale — may fall under tariff lines that carry distinct compliance or licensing requirements.
Gilsonite is a naturally occurring solid hydrocarbon classified among asphaltites and asphaltic rocks; its classification is fact-sensitive, and customs examination that re-characterises the material as a petroleum-derived bituminous substance within Chapter 27 can trigger retrospective compliance and detention pending resolution. Confirm the geological origin, physical form, and intended end-use in documentation accompanying the bill of entry. Where the product is blended or processed, re-classification risk increases materially.
