Hollow bars
Zinc hollow bars, a form of zinc bars and rods
HSN 7904 00 11 (zinc hollow bars) 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 zinc semi-fabricates — including zinc alloy profiles or zinc wire under the same heading — should be verified independently, as classification at the sub-line level determines compliance exposure across Chapter 79.
The absence of compliance at this tariff line applies specifically to zinc hollow bars; zinc products in other forms or alloy compositions may be classified differently within Chapter 79 and could attract distinct compliance obligations. Customs re-classification on examination — for instance, where a declared hollow bar is re-characterised as a profile or a tube — triggers retrospective compliance and detention pending resolution. Verify the product's precise cross-sectional geometry and alloy specification against the customs tariff before filing the bill of entry.
