Textile assistants, hydrosulphite formaldehyde compound (rongalite, formusul)

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 3809 91 50 (textile assistants — hydrosulphite formaldehyde compound, sold under trade names such as rongalite and formusul) 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 finishing agents, dye carriers, and mordants classified within Chapter 38 may carry distinct compliance depending on their specific chemical composition or end-use application.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line applies specifically to the hydrosulphite formaldehyde compound form; finishing agents or reducing auxiliaries with materially different chemical compositions, or those marketed for non-textile end uses, may be classified elsewhere in Chapter 38 under a line that does carry compliance. Re-classification on customs examination triggers retrospective compliance, including detention pending resolution. Verify the product's declared chemical identity and intended application against the tariff description before importing.

Frequently asked

Does HSN 3809 91 50 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 finishing agent has a different chemical composition or is used outside the textile industry?

Finishing agents or chemical preparations with a distinct composition or non-textile application may fall under a different tariff line within Chapter 38 that attracts its own compliance requirements, and re-classification by customs to such a line triggers retrospective compliance.
