The chemical compound sodium tripolyphosphate, or STPP for short, has the formula Na5P3O10. It is an inorganic salt made up of the tripolyphosphate anion (P3O105-) and sodium cations (Na+). The capacity of STPP to maintain pH levels, speed up soil degradation, and sequester minerals in hard water to increase surfactant efficacy are just a few of its many benefits. It is created by neutralizing phosphoric acid, which can be made using thermal or wet methods. To obtain a high yield of the intended final product, sodium tripolyphosphate is made up of one unit of monosodium orthophosphate and two units of disodium orthophosphate, which are thoroughly mixed.

While sodium tripolyphosphate (STP) is a hydrated form with water molecules in its crystal structure, sodium tripolyphosphate (STP) is an entirely aqueous chemical compound. This kind of sodium tripolyphosphate is used in ceramics, paints, and coatings as a dispersion agent, deflocculant, and corrosion inhibitor, among other industrial uses.
Under IS standard IS 6100:2021, all sodium tripolyphosphate, anhydrous, technical has been included in the required ISI Certification Scheme.
This standard describes the precise requirements for technical-grade anhydrous sodium tripolyphosphate, which is used as a detergent builder and deflocculant, along with the sampling and testing procedures. Sodium tripolyphosphate should make up the majority of the material, which should also be a white, homogeneous, free-flowing powder free of any apparent imperfections. The material must fulfill the standards criteria when put through the recommended testing procedure.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.
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.

There are two approaches for Indian manufacturers to become certified with the ISI Mark:
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
Step 2: Submission of the Application Form

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
Step 2: Sample Testing
