Ortho-phosphoric acid, commonly known as phosphoric acid, is a critical industrial chemical used across food processing, pharmaceuticals, fertilizers, and various manufacturing sectors. In India, the production, import, and sale of ortho-phosphoric acid are regulated under the Bureau of Indian Standards (BIS), making BIS certification for ortho-phosphoric acid mandatory for market compliance.

This comprehensive guide covers everything you need to know about BIS registration for ortho-phosphoric acid, the IS 798:2020 standard, CRS (Compulsory Registration Scheme) requirements, and how to navigate the certification process efficiently.

Understanding IS 798:2020 for Ortho-Phosphoric Acid

IS 798:2020 is the Indian Standard specification for ortho-phosphoric acid (food grade). This standard, published by the Bureau of Indian Standards, defines the quality parameters, purity requirements, testing methods, and packaging specifications for ortho-phosphoric acid intended for use in food and beverage applications.

The standard covers:

  • Chemical composition and purity levels
  • Physical properties (appearance, odor, specific gravity)
  • Maximum permissible limits for impurities
  • Heavy metal content restrictions
  • Arsenic and lead limits for food safety
  • Packaging and labeling requirements
  • Sampling and testing methodologies
  • Storage and handling guidelines

Compliance with IS 798:2020 ensures that ortho-phosphoric acid meets food safety standards and is suitable for applications in soft drinks, food acidulants, and pharmaceutical formulations.

Why BIS Certification for Ortho-Phosphoric Acid is Mandatory

The Bureau of Indian Standards has brought ortho-phosphoric acid under the Compulsory Registration Scheme (CRS), making BIS certification for ortho-phosphoric acid mandatory for:

Domestic Manufacturers:

  • Cannot manufacture or sell ortho-phosphoric acid without valid BIS license
  • Must display BIS Standard Mark (ISI) on products and packaging
  • Required to maintain consistent quality as per IS 798:2020
  • Subject to periodic surveillance and market testing

Importers:

  • Cannot import ortho-phosphoric acid without BIS registration
  • Must obtain BIS CRS certification for ortho-phosphoric acid before customs clearance
  • Required to register foreign manufacturing facilities with BIS
  • Subject to sample testing and quality verification at Indian ports

Market Impact:

  • Retailers and distributors can only stock BIS-certified products
  • Food and beverage manufacturers must source certified ortho-phosphoric acid
  • Non-compliance attracts penalties, product seizure, and legal action
  • Government procurement mandatorily requires BIS certification

The mandatory nature of this certification makes engaging a BIS consultant for ortho-phosphoric acid essential for timely and compliant market entry.

What is CRS Certification for Ortho-Phosphoric Acid?

The Compulsory Registration Scheme (CRS) is BIS's regulatory framework for products affecting public health and safety. CRS certification for ortho-phosphoric acid represents the mandatory compliance pathway under this scheme.

Key features of CRS certification:

Simplified Process: Unlike the traditional BIS licensing scheme, CRS offers a streamlined registration process with faster approvals, making it more accessible for manufacturers and importers.

Self-Declaration Based: Manufacturers self-certify compliance with IS 798:2020 based on their own testing or testing from BIS-recognized laboratories, reducing bureaucratic delays.

Mandatory Testing: Despite self-declaration, products must undergo testing at BIS-recognized laboratories to verify conformity with standard specifications.

Registration Validity: CRS certification for ortho-phosphoric acid is typically valid for one year and must be renewed annually with updated compliance documentation.

Surveillance Mechanism: BIS conducts market surveillance, random sampling, and testing to ensure ongoing compliance. Non-conforming products face immediate action.

Working with an experienced CRS consultant for ortho-phosphoric acid ensures proper understanding and implementation of these requirements.

BIS QCO for Ortho-Phosphoric Acid Explained
