ISI / BIS Certification for Polyester Staple Fibres (PSF)

Synthetic fiber known as polyester staple fiber (PSF) is created by polymerizing polyester constituents such monoethylene glycol (MEG) and purified terephthalic acid (PTA) at high pressure and temperature. The polyester material is melted to create these fibers, which are then extruded through a spinneret to create long, continuous strands. To make staple fibers, these strands are chopped into shorter lengths, usually between a few millimeters and a few centimeters.

The resilience of polyester staple fibers to various chemicals, moisture, and mildew is only one of its many benefits. They are renowned for being strong, drying quickly, and holding their color and form after multiple washings and uses. PSF's luster classifies it as either brilliant or semi-dull. Opaque white, black, and other colors can be achieved with dope-dyed PSF by using a color masterbatch. PSF is a well-liked option in many textile and non-textile applications because of these qualities. 

PSF is widely utilized in the filtration sector, wadding, non-woven carpets, and yarn manufacture. In addition, it's utilized in spinning yarns, creating geotextiles, and filling cushions, pillows, soft toys, and comforters as a polyfill.

A number of factors, such as the state of the global textile industry, customer tastes, and economic situations, affect the demand for polyester staple fibers (PSF). Its increasing use in home furnishings, filtration, and automobile interiors is fueling demand. The demand for recycled polyester staple fiber and the growing inclination for biodegradable and renewable synthetic fibers are also propelling the expansion throughout the projected time. 

Under IS standard IS 17263:2022, all polyester staple fibers (PSF) are now covered by the required ISI Certification Scheme.

In order to receive BIS registration, polyester staple fiber (PSF) manufacturers are required to comply with particular quality and testing criteria.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.

About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

Process of ISI / BIS Certification

There are two approaches for Indian manufacturers to become certified with the ISI Mark:

• Regular Procedure
• Simplified Procedure 

Regular Procedure

With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.

Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities as per the Standard's requirements

Step 2: Submission of the Application Form

• Preparing an Internal Test Report for the product by the relevant Indian Standard
• Compiling all necessary documents
• Completing the Online Application Form
• Online payment of application fees directly to BIS
• Submitting hard copies of the Application Form with all enclosures to the relevant Branch Office (BO) of BIS

Simplified Procedure

This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.

Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities to meet the Standard's requirements

Step 2: Sample Testing

• Obtaining the necessary certificate for raw materials (Material Test Certificate - MTC)
• Conducting product sample testing at a BIS-recognized testing laboratory
