Flint button
Flint button glass for corrective spectacles, not optically worked
HSN 7015 10 20 (Flint button — glass for corrective spectacles, not optically worked) 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 glass products within Chapter 70 — including optically worked ophthalmic glass blanks and finished corrective lenses — may fall under sibling tariff lines that carry distinct compliance obligations.
The absence of compliance at this tariff line applies specifically to unworked flint button glass blanks; once a product is optically worked or finished into a corrective lens, classification shifts and the applicable compliance regime may change accordingly. Customs re-classification on examination — for instance, where the goods are assessed as optically worked — triggers retrospective compliance and potential detention pending the relevant clearance. Verify the optical-working status and intended end-use of the glass against the customs tariff before relying on the absence of compliance here.
