Silk fibre doubling or twisting machines
Silk fibre doubling or twisting machines for textile yarn production
HSN 8445 30 40 (Silk fibre doubling or twisting 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, bill of entry, commercial invoice, packing list. Other textile machinery under Chapter 84 — including spinning machines, weaving machines under heading 8446, and knitting machines under heading 8447 — may carry distinct compliance requirements depending on the specific machine type and applicable notifications.
The principal importer risk at this tariff line is misclassification: doubling or twisting machines for fibres other than silk are classified under sibling lines within heading 8445, and a customs re-classification — whether by fibre type or by functional description — triggers retrospective compliance obligations and potential detention. Verify the machine's technical specification, including fibre type and mechanical function, against the customs tariff before filing the bill of entry.
