Flexible tubing of iron or steel, with or without fittings
HSN 8307 10 00 (flexible tubing of iron or steel, with or without 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. Flexible tubing of other base metals — copper, aluminium, or nickel alloys — classified elsewhere in Chapter 83 may carry distinct compliance considerations, and certain end-use applications such as gas-supply fittings may attract sectoral requirements.
The principal importer risk at this tariff line is misclassification: rigid or semi-rigid iron and steel conduit, pipe fittings, and tube assemblies classified under Chapter 73 carry separate compliance regimes, and customs re-examination that results in re-classification triggers retrospective compliance obligations including detention pending the relevant determination. Verify that the goods are genuinely flexible tubing — not rigid pipe, not tube fittings separately classified — and confirm the base-metal composition before relying on the absence of compliance at this line.
