Yarn made of 100% inherent FR synthetic fibre

Yarn of 100% inherent fire-retardant synthetic staple fibres

DGFT CLEARANCE

HSN 5509 99 10 (Yarn made of 100% inherent FR synthetic fibre) is subject to the ITC (HS) import policy administered by the Directorate General of Foreign Trade (DGFT), which restricts import to yarn whose fire-retardant properties are permanently embedded in the polymer backbone as specified under IS 11871, IS 13501, and IS 15742/15742A per DGFT Notification 20/2015-20 dated 07-07-2022. A Pre-Shipment Inspection Certificate covering the absence of prohibited hazardous azo dyes is additionally required under General Note 10 of the ITC (HS) policy.

Compliance steps

1
Confirm that the imported yarn qualifies as 100% inherent FR synthetic fibre under the Chapter 55 supplementary note: the fire-retardant properties must be permanently part of the polymer backbone and cannot be worn away or washed out, as specified in IS 11871, IS 13501, IS 15742 and IS 15742A. Yarn whose FR properties are applied as a surface treatment does not qualify under this CTI and must be classified elsewhere.

2
Obtain a Pre-Shipment Inspection Certificate from an accredited laboratory in the exporting country, or a valid test report from a Textile Committee or CSRTI laboratory, certifying the absence of prohibited hazardous azo dyes. Testing for azo dyes is exempted only for imports originating from the EU, Serbia, Poland, Denmark, Australia, Canada, Japan, South Korea and the United Kingdom.

A word of counsel

The single most common error on this tariff line is presenting yarn that has been topically treated with a flame-retardant finish and asserting it qualifies as inherent FR fibre under CTI 5509 99 10. The Chapter 55 supplementary note demands that FR properties be intrinsic to the polymer backbone — surface-applied FR finishes fail this test, and misdeclaration exposes the importer to reclassification, confiscation of the misdeclared consignment, and monetary penalty under the Customs Act, 1962. Secure a pre-shipment technical data sheet confirming backbone-level FR architecture before dispatch.

Frequently asked

Does HSN 5509 99 10 require BIS certification?

No, no BIS Quality Control Order covers this tariff line. Import is governed by the ITC (HS) policy administered by the Directorate General of Foreign Trade, with classification conditional on conformance to IS 11871, IS 13501, and IS 15742/15742A as referenced in the Chapter 55 supplementary note under DGFT Notification 20/2015-20.

Is a Pre-Shipment Inspection Certificate required for all countries of origin?

Yes for most origins. Testing for the presence of prohibited azo dyes is exempted only for imports from the EU, Serbia, Poland, Denmark, Australia, Canada, Japan, South Korea and the United Kingdom; for all other exporting countries a PSIC from an accredited laboratory or a Textile Committee/CSRTI test report is mandatory per DGFT Public Notice 14/2023.

What distinguishes inherent FR fibre from topically treated FR yarn for classification under this CTI?

Per the Chapter 55 supplementary note referenced in DGFT Notification 20/2015-20, inherent FR fibres are those where the flame-retardant properties are naturally part of the polymer backbone and can never be worn away or washed out; yarn treated with external FR finishes does not satisfy this definition and cannot be declared under HSN 5509 99 10.
