Sodium Tripolyphosphate is essential for use in detergents, water treatment chemicals, ceramics and other industrial cleaning agents. BIS certification of Sodium Tripolyphosphate Anhydrous has become a regulatory requirement for use of the chemical in industries in India. It is used in industrial processes as a detergent builder, deflocculant, and processing agent where the purity and efficacy of the chemical are critical to its efficacy in the manufacturing process.
Due to increasing regulation with respect to chemical products, there is a need for quality systems that would prove compliance. IS 6100:2021 lays out specifications pertaining to chemical properties, physical properties, sampling and testing methods for sodium tripolyphosphate anhydrous technical grade. The article provides details of the specification, certification process, testing, documentation and approvals needed for the chemical compound.
Technical Compliance Requirements for IS 6100:2021
This is the Indian Standard for sodium tripolyphosphate anhydrous technical grade used in detergents, water treatment, and industrial cleaning formulations. It ensures consistent chemical performance and formulation efficiency. As per BIS, STPP is:
- Evaluated for solubility
- Tested for insoluble matter
- Checked for phosphorus content
- Assessed for moisture
Who Requires BIS Certification for Sodium Tripolyphosphate
BIS authorisation under IS 6100:2021 is required for businesses involved in manufacturing, importing, or supplying Sodium Tripolyphosphate anhydrous in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the products are covered under QCO.
- Foreign Manufacturers - Need certification to export the white crystalline inorganic salt to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified salt (Na5P3O10).
Testing and Inspection Requirements
In order to ensure the consistent behaviour of sodium tripolyphosphate anhydrous in the preparation of detergents and water treatment preparations, BIS provides guidelines under the specification of IS 6100:2021. These guidelines ensure the proper composition of chemicals and the moisture content of the compound.
The BIS testing parameters and quality checks for the sodium tripolyphosphate are listed below:
How is BIS Approval granted under IS 6100:2021
The BIS approval process under IS 6100:2021 ensures that Sodium Tripolyphosphate, Anhydrous, Technical grade complies with the quality and purity requirements specified by the Bureau of Indian Standards (BIS). This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for chemical composition, moisture content, phosphorus levels, pH value, insoluble matter and impurity limits.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: BIS officials visit the manufacturing facility to evaluate production processes, safety measures, and the quality control system.
- Grant of BIS License: After all compliance requirements are satisfactorily met, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Following approval, the manufacturer is authorized to use the ISI Mark on the product along with a valid CM/L number, confirming that the product meets BIS standards.
