Flint

Flint, whether or not heat-treated

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2517 10 20 (Flint) 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 materials under heading 2517 — such as tarred macadam or granules and chippings of stones from headings 2515 or 2516 — may fall under sibling tariff lines where specific classifications apply.

No partner government agency notification covers this tariff line.
A word of counsel

Flint imported under this tariff line must be correctly distinguished from processed stone materials — granules, chippings, or powder — derived from marble, granite, or similar stones of headings 2515 or 2516, which are separately classified within Chapter 25. Re-classification on customs examination triggers retrospective compliance, including detention pending resolution. Verify the product's physical form, intended use, and processing state against the customs tariff schedule before filing the bill of entry.
