What is NSF?

NSF International is an American product testing, inspection, and certification organization based in the U.S. that specializes in the safety of food, water, and consumer products.

What does an NSF certification mean?

A product certified by NSF informs the consumer that the product or company complies with NSF standards and procedures. NSF provides extensive product testing and material analyses, as well as conducting plant inspections. NSF will evaluate every aspect of a product’s development before it can earn an NSF certification.

Once certified, the product or company will undergo annual review and inspection to ensure the product and/or processes remain compliant.

Products that earn NSF certification are said to be “NSF certified” or “NSF listed” and display the applicable NSF certification mark to show that they have been tested by one of today’s most respected independent product testing organizations.

NSF certification mark

An NSF-certified product will have this mark on the label, including information about which category the product has been certified for.

NSF Categories

NSF certified products are identified with the NSF logo, and with an alpha-numeric code. Each letter represents a different category of product, and the number represents a sub-category. For example the “A” category covers cleaning agents as a group, and a product with certification “A1” falls into the general cleaners sub-category.
