Threading machines

Metal-cutting threading machines for industrial use

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8459 70 10 (Threading machines) 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 machine-tools within Chapter 84 — particularly numerically controlled machining centres and tapping machines — may be classified under distinct tariff lines that carry separate compliance obligations.

No partner government agency notification covers this tariff line.

A word of counsel

The principal importer risk at this tariff line is misclassification: threading machines that incorporate tapping capability, or that are numerically controlled, may be assessed by customs as falling under a more specific heading within Chapter 84, triggering retrospective compliance and potential detention pending re-classification. The distinction between threading and tapping functions — and between manually controlled and CNC variants — should be documented in the technical specification supplied to the customs broker before filing the bill of entry.

Frequently asked

Does HSN 8459 70 10 require any pre-import registration?

A valid Importer-Exporter Code is required for any commercial import; no product-specific registration applies to this tariff line.

What changes if the machine also performs tapping operations?

Machines combining threading and tapping functions may be assessed under the tapping-machine tariff line within Chapter 84, which could attract distinct compliance obligations on re-classification by customs.
