GOTS Certification: The Global Organic Textile Standard

"Organic" on a clothing label can mean almost anything a marketing department wants it to mean — unless the product is certified. The Global Organic Textile Standard, known everywhere as GOTS, is the certification that gives the word a fixed, audited meaning in textiles. It is the most widely used organic textile standard in the world, and it is deliberately demanding: it does not stop at the fiber, but follows a product through spinning, weaving, dyeing, finishing, sewing and trading, checking environmental and social criteria at every stage.

This is the full Apparel Search guide to how GOTS works. A shorter reference version lives in our glossary — GOTS certification in brief — while this page covers the standard's scope, label grades, criteria and certification process in depth.

Scope: From Fiber to Finished Garment

GOTS covers the processing, manufacturing, packaging, labelling, trading and distribution of textiles made with certified organic fibers. The fibers themselves — cotton, wool, silk and others — must first be certified organic under a recognized organic agriculture standard. From the first processing stage onward, GOTS takes over: ginning, spinning, knitting and weaving, wet processing such as dyeing and printing, finishing, garment making, and the traders who move certified goods between them. A certified entity is approved for defined operations and product categories, listed on its scope certificate, and each stage must keep certified material identified and segregated from conventional stock so the claim cannot leak or dilute along the way.

The Two Label Grades

GOTS products are labelled in one of two grades, and the wording matters. The top grade, "organic," requires at least 95 percent certified organic fibers. The second grade, "made with organic," requires at least 70 percent certified organic fibers, with the grade statement naming the percentage. The remaining share of the product is not a free choice: the standard restricts which additional fibers may be used and in what combinations, so conventional cotton, for example, cannot simply be blended into a product carrying the top grade. Accessories and trims, from buttons to interlinings, are also regulated, with rules on materials and prohibited substances. When you see GOTS on a label, the grade, the certification body and the licence number should all be printed with it — that combination is what makes the claim checkable.

Key Criteria

Three families of rules do most of the work. Chemical criteria govern every input used in processing: dyes, auxiliaries and finishes must be assessed and approved, and substances known to be hazardous — among them toxic heavy metals, formaldehyde and aromatic solvents, and inputs produced with GMOs — are prohibited. Environmental criteria require wet-processing units to treat their wastewater in a functioning effluent treatment plant, and set expectations for energy, water and waste management. Social criteria, drawn from the core conventions of the International Labour Organization, apply at every certified facility: employment must be freely chosen, child labor is prohibited, workers must be able to organize, conditions must be safe and hygienic, and wages must meet legal and industry benchmarks, with the standard pushing toward a living wage. Certified products must also meet technical quality parameters — measures such as colorfastness and dimensional stability — so that a GOTS garment performs as clothing, not just as a claim.

How Certification Works

Certification is carried out by independent certification bodies approved by the GOTS organization (Global Standard gGmbH, the non-profit that owns and develops the standard). A facility applies, is inspected on site — records, chemical inventories, wastewater arrangements, worker interviews — and, on approval, receives a scope certificate for its defined operations, renewed through annual inspections. As certified material moves between certified companies, the transfer is documented with transaction certificates, creating an unbroken paper chain from fiber processor to finished product. Buyers can ask for a supplier's scope certificate, and the GOTS public database lets anyone confirm that a company is genuinely certified and for what.

How GOTS Compares

GOTS is the heavyweight among the fiber standards in this series. The Organic Content Standard verifies organic content and custody only, without processing or social rules. The Global Recycled Standard and Recycled Claim Standard do the equivalent job for recycled fibers, GRS adding facility requirements of its own. bluesign approaches from chemistry and production inputs rather than fiber origin. And where the buyer's concern is the people rather than the fiber, Fair Trade certification addresses prices, premiums and wages from the economic side. Many products carry two labels at once, because no single standard answers every question.
