    About GOTS Scope 4 Approval

    The aim of the Global Organic Textile Standard(GOTS) is to define requirements to
    ensure organic status of textiles. Since it is difficult to carry out industrial production of textile products without using any chemicals at all, GOTS permits the use of “chemicals with low environmental impact and low persistence” and has established standards for them.

    What is valid GOTS LOA?

    Chemical inputs used for wet-processing of GOTS Goods and Accessories used for functional and/or fashionable reasons are collectively called GOTS Additives. Both categories have different technical requirements in line with their production and usage. With the implementation of GOTS Version 7.0, chemical formulators are required to implement product stewardship practices and undergo an on-site audit for environmental management systems, as well as occupational health and safety. Traders or distributors may apply for GOTS certification under their own brand name only if the original manufacturer holds a valid GOTS certificate for that product. Furthermore, such certified chemical products may be listed on the official GOTS website and used as inputs by GOTS-certified companies for the purpose of meeting the standard.

Under the GOTS system, only those inputs can be used, which have been assessed and approved according to the Standard by a Scope 4 GOTS Approved Certifier.
