NSF/ANSI 336 Facts Sustainability Certification

We are an approved certification body for the Association for Contract Textiles’ Facts certification, which indicates that a textile has met the NSF/ANSI 336 standard and provides manufacturers with third-party certification of their sustainable products.

A variety of different colored fabrics hang on a rack.


Purchasers and specifiers of textile fabrics want to know that the products they select for public spaces are reliable and dependable. The purpose of the NSF/ANSI 336 standard is to address the environmental, economic and social aspects of commercial furnishing fabrics used in commercial spaces. The standard considers criteria from a product’s lifecycle to get a complete picture of the inputs, outputs and environmental impacts of textile products across a product’s lifespan. The standard is applicable to a variety of contract fabric types used in public spaces, such as office, hospitality, healthcare and institutional interiors. As a multi-attribute sustainability standard, NSF 336 considers eight sustainability parameters that carry varying weight in the total point make-up; 50 percent comprises the fiber composition, and the remaining 50 percent comprises the fabric manufacturing process.

Certified fabrics must meet prerequisites for each parameter and can achieve optional credits, earning up to a maximum of 100 points. Based on the total number of points achieved within each category, products are awarded certification levels of compliant, silver, gold or platinum. Products certified to NSF 336 are certified for five years and undergo yearly reviews to determine continued compliance to the standard.
