NSF Certifies Hanwha As First Client to NSF Guideline 533

The certification demonstrates that their resins have been evaluated for health effects and are safe for use in drinking water products.

Seoul, South Korea – NSF, the leading testing and certification organization in the water industry, is pleased to announce that Hanwha Solutions Corporation (Hanwha), a South Korea-based petrochemical company, has earned certification to NSF Guideline 533 for its HC-17 and HC-77 CPVC resins products. Hanwha is NSF’s first client in the world to receive this certification, which demonstrates that their resins have been evaluated for health effects and are safe for use in drinking water products.

Founded in 1965, Hanwha has been at the forefront of the South Korean petrochemical industry and produces a full array of basic petrochemical products.

“Hanwha is committed to providing high-quality and safe products while meeting the requirement of the relevant industry. The NSF mark is highly valued by the industry and adds credibility to our products,” said Dooyoung Jung, Head of PVC Business Division, Hanwha. “We are proud to have earned this certification, which helps us to be more competitive in the global market.”

NSF Guideline 533 is a new guideline that NSF launched in January 2023. The guideline covers ingredients such as resins, stabilizers, carbon black, lubricants, solvents, and colorants used in CPVC, PE, Nylon, and other materials. It expands NSF’s certification offerings to include ingredients used in drinking water products to further strengthen its commitment to ensuring the safety and quality of drinking water products. Certified ingredient manufacturers can use the dedicated NSF mark to prove that their product is safe as reviewed by a third party.

“We launched NSF Guideline 533 this year and are proud to certify the first company, Hanwha Solutions, “said Nasrin Kashefi, Senior Manager of Residential Water at NSF. “We offer a simple process that saves ingredient manufacturers time and cost. With NSF Guideline 533, ingredient manufacturers have the opportunity to promote their ingredients to drinking water product manufacturers around the world on NSF’s official website. For product manufacturers, using NSF-listed ingredients can help them get to market quickly.”

Additionally, the NSF Guideline 533 certification program provides a listing that allows ingredient manufacturers to market their ingredients as NSF certified, which can help facilitate the listing of their customer's products under NSF/ANSI 14 and NSF/ANSI/CAN 61.
