Komal28 July 2025

India’s textile industry is transitioning to a more quality-driven framework, anchored by mandatory product standards. A key part of this shift is IS 17265:2023, which governs 100% Polyester Spun Grey and White Yarns. With this standard now legally enforceable under a Government Quality Control Order (QCO), compliance is not just important—it’s essential. Omega QMS Pvt. Ltd. is at the forefront, helping manufacturers achieve BIS/ISI certification quickly and effectively.IS 17265:2023 and BIS Certification – Now Mandatory

The Ministry of Chemicals and Fertilizers has issued a Quality Control Order (QCO) making it mandatory for manufacturers of polyester spun yarn to obtain BIS certification and affix the ISI mark on their products. The yarns must comply with the specifications laid out in IS 17265:2023, which covers:

Physical properties like linear density, tenacity, elongation, twist, and CSP
Chemical parameters such as moisture regain, whiteness index, and UV resistance
Packaging, marking, and sampling guidelines for conformity assessment

Non-compliance may lead to serious legal implications, including product bans and financial penalties.

Key Technical Highlights of IS 17265:2023

IS 17265:2023 is a comprehensive standard that defines quality benchmarks for both virgin and recycled polyester yarns, produced using ring spun, air-jet, or vortex spinning methods. Notable requirements include:

Count Strength Product (CSP): Minimum values defined by yarn type and fineness (e.g., ≥5400 for coarse ring-spun yarns)
Hairiness Index: Varies by count (e.g., ≤9 for 16s–32s Ne ring-spun yarn)
Whiteness Index: ≥115 for optically white yarn; defined minimums for dull and recycled grades
Moisture Regain: Limited to ≤1.0%
Objectionable Faults: Strict limits per 100 km of yarn
Additional Optional Tests: Eco-mark criteria for restricted substances, UV resistance, antimicrobial activity, etc.

The standard also specifies sampling plans, packing instructions, and requires each product lot to be clearly marked with yarn details, batch numbers, and manufacturer identity.
