Silvin Additives, a leading manufacturer of PVC and CPVC additives, has earned the NSF Guideline 533 certification for its CPVC Super1Pack. The certification confirms that the formulation complies with stringent safety and health standards for products used in drinking water applications.

Headquartered in Michigan, US, NSF is a globally recognised authority in public health and safety. Its certification involves rigorous testing and inspections to ensure compliance with strict quality, sanitation, and safety standards. NSF Guideline 533 specifically evaluates ingredients used in products that come into contact with drinking water, confirming that they meet stringent health-effects criteria for safety and regulatory compliance.

Silvin’s products are widely used in plumbing, agriculture, SWR (soil, waste and rainwater) drainage, and column and riser systems. The NSF certification strengthens Silvin’s position as a trusted partner to the pipes and fittings manufacturing industry.

Commenting on the certification, Jagat Chokshi, Managing Director, Silvin Additives, said, “At Silvin, we have always prioritised quality and safety. Our additives are a key ingredient of pipes and fittings, which are critical in delivering safe drinking water. Receiving NSF® certification is a validation of our commitment to producing additives that meet global standards. This recognition will help us unlock new opportunities and expand our international presence.”
