This internationally recognized standard is awarded by the „International Working Group on GOTS" . IVN is a member of this group. Therefore GOTS is an indirect IVN standard, despite the fact that our association was a leader in its development. The now defunct standard „IVN zertifiziert“ was inspiration and role model for the new GOTS standard and many of its provisions were integrated into GOTS.
GOTS requirements are less stringent than those of NATURTEXTIL IVN certified BEST. For IVN, GOTS therefore represents the minimum standard for products to be considered eco-friendly.
As GOTS and NATURTEXTIL IVN certified BEST are largely similar, the following lists only the differences between the two. To read the specific requirements for BEST , click here: BEST standard

The most important difference between the two standards is the minimum content of certified natural fibers. A product certified with the GOTS label must contain at least 90% natural fibers; at most 10% can be synthetic or rayon. Only socks, leggins and sports apparel can contain up to 25% synthetic fibers. Independently of this requirement, a minimum of 70% of animal or plant fiber content must be certified organic origin (kbA oder kbT).
The list of permitted dyes and helping agents is longer for GOTS than for BEST. For example an exception is made for heavy metal copper in dyestuffs.
Mercerization, the processing of cotton yarns in caustic soda to increase sheen is permitted for GOTS. Optical brighteners are also permitted.
For GOTS, trimmings and accessories such as interfacing, embroidery yarn and ribbons and bands can be made of rayon; they must not necessarily be made of natural fibers. Buttons made of synthetic materials are also allowed.
