Tube or pipe fittings
Nickel tube or pipe fittings (couplings, elbows, sleeves)
HSN 7507 20 00 (nickel tube or pipe fittings) 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 articles of nickel, including certain finished mechanical components, may attract compliance obligations under Chapter 75 or under the chapter governing the end-use equipment into which the fittings are incorporated.
The absence of compliance at this tariff line does not extend to nickel articles in other forms: nickel tubes and pipes classified separately within Chapter 75, or fittings of other base metals in their respective chapters, may each carry distinct obligations. Re-classification by customs — on grounds of alloy composition, wall thickness, or end-use declaration — triggers retrospective compliance and potential detention. Verify the precise alloy specification and intended application against the customs tariff before relying on the absence of compliance.
