NSF product certification steps
Different certification schemes
have different certification procedures due to different products.
Generally, a complete authentication process consists of the following
seven steps:
1. Application
The applicant should first
fill in the application form for each production site to be listed, date
it and sign it. Submit the completed application form to NSF. After
receiving the application form and the certification fee in advance, NSF
will assign a project manager as the project contact for the applicant
to be responsible for the whole certification process and any new
projects in the future.
2. Submit product information (including product formulation and / or toxicological information, product application, etc.)
Submit a complete product information form (PIF) for each product / material family you want to certify.
3. Review of product formula
Toxicologists
will review the formulation of product component materials and
determine which substances need to be tested for chemical analysis
according to the corresponding standards. An unlicensed registered
formula (URF) file will be issued to each production site and used for
site review for validation.
4. Quality assurance (QA) review and product sampling of production site
NSF
auditors or representatives assigned by NSF will conduct audits at each
final production site. The audit can be carried out with information
collection, formula review and other steps, or at the same time with
laboratory testing.
The NSF auditor will inspect the
manufacturing site and verify that its product components, materials and
suppliers are consistent with the description on the product
information sheet (PIF) submitted to NSF. If necessary, the auditor will
take samples from the previous production batch and / or the current
production batch for NSF laboratory testing.
5. Laboratory test of products
This test is based on the corresponding standards for laboratory analysis of products
6. Toxicological evaluation of experimental results
This
is the final toxicological assessment of the results. If the evaluation
results show that the product meets the requirements of the standard,
NSF will issue a license registration formula (ARF) to each production
site for use in future annual reviews.
7. Official listing
When
the product fully meets all the above requirements, the applicant will
receive the certificate issued by NSF and be listed on the official
website of NSF. The listing year of NSF begins on January 1 of each
year, when all column names will be updated. The listed production sites
shall ensure that the products they produce and provide continuously
comply with the corresponding standards and program policies. NSF
usually ensures its compliance through annual surprise factory reviews
and monitoring tests.
