NSF launches PFAS-Free certification scheme in Thailand

NSF, the global public health and safety organisation, has introduced a new certification guideline in Thailand aimed at verifying products as free from per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals”.

The launch of NSF Certification Guideline 537 (NSF 537) allows manufacturers of food equipment materials and nonfood compounds—such as lubricants, cleaners, and sanitisers—to demonstrate that their products contain no intentionally added PFAS and meet rigorous testing standards.

PFAS are synthetic chemicals used to make products water-, oil- and grease-resistant. However, these compounds are linked to serious health risks including certain cancers, liver disease, and developmental delays. They are also persistent in the environment, prompting increasing scrutiny and regulation.

Sam Cole, director of food contact evaluation at NSF, said that the new certification standard provides manufacturers with a transparent means to stand out in the marketplace while addressing rising consumer and regulatory concerns about PFAS exposure.

NSF 537 includes stringent requirements such as comprehensive formulation reviews, annual retesting for total organic fluorine (TOF), and full disclosure of manufacturing practices to avoid cross-contamination. Certified products are eligible to carry the official NSF PFAS-Free mark and are listed publicly in NSF’s White Book™ and Certified Food Equipment database.

Jyoti Bhasin, managing director for APAC at NSF, said that the scheme is expected to open up global export opportunities and position manufacturers as leaders in product safety and sustainability.

To be eligible for NSF 537 certification, nonfood compound products must already be registered under NSF’s Nonfood Compounds Guidelines or certified to ISO 21469. Food equipment materials must meet NSF/ANSI Standard 51 to confirm compliance with public health and sanitation benchmarks.
