Hollow bars
Tantalum hollow bars, unwrought or simply sintered
HSN 8103 20 10 (tantalum hollow bars, unwrought or simply sintered) 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, bill of entry, commercial invoice, packing list. Other forms of tantalum and articles thereof within Chapter 81 — including worked articles, alloys, or waste and scrap — may be classified under distinct tariff lines that carry separate compliance considerations.
The absence of compliance at this tariff line does not extend to tantalum in other forms or states: wrought tantalum articles, tantalum-based alloys, and tantalum waste and scrap are each classified separately within Chapter 81 and may attract distinct requirements. Re-classification on customs examination — for instance, if the bar is determined to have been further worked — triggers retrospective compliance, including potential detention pending resolution. Verify the precise product specification, including sintering state and degree of working, against the customs tariff before filing the bill of entry.
