Sustainable fabric sourcing has moved from a niche requirement to a mainstream expectation, and with that shift has come a proliferation of certifications that sound similar but verify genuinely different things. Understanding what each certification actually covers — and just as importantly, what it does not — is essential for making credible claims and avoiding a green-claims compliance problem down the line.
GOTS — Global Organic Textile Standard
GOTS covers the full supply chain from organic fibre through to finished, labelled fabric — organic raw material at source, restricted chemical processing throughout dyeing and finishing, mandatory wastewater treatment, and fair labour standards audited alongside the technical requirements. It is the most comprehensive textile certification available, and the only one of the four covered here that regulates both processing chemistry and social/labour criteria together. See our full GOTS guide for how the certificate verification process actually works.
OCS — Organic Content Standard
OCS verifies that a product contains a specified, chain-of-custody-verified percentage of organic material. It covers traceability of the organic content only — not the processing standards, chemical restrictions, or social criteria that GOTS adds on top. This makes OCS less rigorous than GOTS, but a genuinely appropriate certification for blended fabrics (organic cotton blended with a non-organic fibre) where full GOTS certification isn't feasible for the blend.
BCI — Better Cotton Initiative
BCI covers responsible cotton farming — reduced water use, reduced pesticide use, and fair labour standards at the farm level — using a mass-balance system rather than physical, bale-level tracing. It's appropriate as a credible baseline sustainability commitment, but the wrong certification to cite for a specific organic or traceability claim on a garment, since it doesn't certify organic content or trace fibre to a specific farm. Our BCI guide covers the mass-balance model in detail.
OEKO-TEX Standard 100
OEKO-TEX Standard 100 tests the finished fabric for harmful substances — over 100 individual chemicals are checked, from heavy metals to formaldehyde to restricted dyes. It does not cover supply chain practices or farming methods at all; it's a product-safety certification, not a sustainability-sourcing certification, and it applies to any fabric regardless of fibre source or how it was farmed.
Choosing the Right Claim
For brands: GOTS supports the strongest, most comprehensive sustainability claim. OCS is the appropriate choice for blended fabrics where full GOTS isn't achievable. BCI demonstrates a genuine, verifiable responsible-sourcing commitment without an organic claim. OEKO-TEX demonstrates product safety and is worth citing regardless of which sourcing certification is also in play.
At Janki Nath & Co., we hold BCI, GOTS, OCS and OEKO-TEX Standard 100 certifications across our manufacturing operations, with full documentation available on request for every order.
