Viscose Staple Fibers' (VSF) BIS certification guarantees adherence to Indian Standard IS 17266:2019, which outlines fiber length, fineness, strength, and elongation, therefore defining conformity. Effective March 29, 2023 BIS certification is required for manufacturing, importing, and selling VSF in India under the Viscose Staple Fibers (Quality Control) Order. Applications for the certification procedure comprise factory inspections, product testing, and acceptance for the ISI Mark. It is good for one year and needs to be renewed if one wants ongoing compliance. Penalties under the BIS Act, 2016 can follow from non-compliance. For VSF producers and suppliers working in India, BIS certification guarantees consumer safety, product quality, and market credibility, therefore ensuring their relevance.
