Parts of miscellaneous machines and mechanical appliances
HSN 8479 90 90 (parts of machines and mechanical appliances having individual functions, not specified or included elsewhere in Chapter 84) 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. The parent heading 8479 covers a wide range of machinery, and parts that are identifiable as belonging to a specific machine elsewhere in Chapter 84 may be classifiable — and compliance-bearing — under that machine's own heading.
The principal risk at this tariff line is misclassification: a part that is specifically designed for a machine covered by a Quality Control Order — such as certain electrical machinery under Chapter 85 or pressure-bearing equipment under Chapter 84 — may be re-classified by customs to the more specific heading, triggering retrospective compliance and detention pending the relevant licence. Classification of parts within Chapter 84 turns on the specificity and exclusivity of the part's function; a general-purpose mechanical component and a dedicated sub-assembly are treated differently. Verify the technical specification and intended application of the part before relying on the absence of compliance at this tariff line.
