ISI / BIS Certification for Sodium Tripolyphosphate, Anhydrous, Technical

The chemical compound sodium tripolyphosphate, or STPP for short, has the formula Na₅P₃O₁₀. It is an inorganic salt made up of the tripolyphosphate anion (P₃O₁₀^5-) 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.

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.

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.

Documents Required for ISI / BIS Certification

The following documentation is required to get an ISI certification:

• Main Application Form V

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

ISI Mark Certification Process for Foreign Manufacturers

The process of obtaining ISI Mark Certification for Foreign Manufacturers typically includes the following steps:

Step 1: Application

• Compile all the required documents.
• Submit the documents along with the Application Fee.
• An Application Number will be allotted.
• Scrutiny of the Application will be conducted within a specified time frame.​

Step 2: Query Raised (If Any)

• If any documents are missing or there is non-compliance, you will be informed.
• You need to submit a reply within the given timeframe.
