What GOTS certification actually means in apparel sourcing

Two things about GOTS surprise buyers who have only met it as a phrase on a fabric offer. It is not restricted to cotton, and it does not certify fabric in isolation: it certifies companies, across the processing chain, and the fabric is certified because the company that made it is.

The standard is owned by Global Standard, published as the Global Organic Textile Standard, and the current version is GOTS 8.1. What follows summarises how the system works for sourcing purposes. It does not reproduce the standard, which is a published document in its own right.

What it covers

GOTS applies across the textile processing chain: fibre processing and spinning, wet processing, manufacturing and trading. It combines environmental requirements with social requirements, and certification is carried out by independent approved certification bodies rather than by the standard owner.

On fibre, the scheme is broader than its reputation. It applies to a range of certified organic natural fibres, vegetable and animal: cotton, hemp, linen and flax, jute, and wool, cashmere, mohair, alpaca and silk. Describing GOTS as an organic cotton certificate is a useful shorthand and an inaccurate one, and it matters when a programme involves a blend or a fibre other than cotton.

Every processing company has to be certified

This is the provision that answers many buyer questions, and it is worth stating plainly. Each company involved in processing the product must itself be certified by an approved independent certification body. Brands, manufacturers, processors, traders and retailers can all be certified entities within the system.

So a garment does not become GOTS certified by being sewn from GOTS fabric. It becomes certified when the organisation that made it is certified for that process and the goods have moved through the chain with the documentation the scheme requires. A certified mill supplying an uncertified factory has supplied certified fabric into an uncertified step, and the chain ends there.

The two label grades

GOTS distinguishes two grades by certified organic fibre content, and the difference is a real one for what a product may be called.

The thresholds are the standard's, not a convention, and they interact with the rest of the specification. A blend designed for performance or price can fall below the grade a brand intended to claim, which is the kind of conflict better discovered at fabric selection than at labelling. Blend behaviour generally is covered in cotton and polyester blends.

The documents that move with the goods

A certified entity holds a certificate identifying it and the scope it is certified for. Separately, transaction certificates are issued after verification when GOTS goods move along the certified supply chain, and certified entities purchasing organic fibres receive and maintain them for the whole quantity purchased.

GOTS also requires the place of origin of raw organic fibre entering the system, by country, region and province, to be declared on the initial transaction certificate from the farm. That is worth knowing because it shows what the transaction chain is for: it is traceability evidence, not administrative overhead, and it is the part a scope certificate alone cannot provide.

How the two document types differ, and what each one does and does not prove, is set out in scope and transaction certificates.

GOTS against a content standard

Buyers sometimes compare GOTS with a content standard such as the Organic Content Standard and ask which is better. They verify different things, so the comparison is really a question about what the programme needs.

A content standard is built to verify the presence and amount of a specified material through the chain. GOTS does that and also carries processing requirements, including environmental and social criteria, across the stages it covers. A programme that needs to substantiate how much certified organic fibre is present has a different requirement from one that needs to substantiate how the textile was processed, and the right answer follows from which of those the buyer actually has to stand behind.

What to verify

GOTS operates a public database of certified suppliers, which is the point of verification rather than the certificate a supplier emails. A PDF confirms what was true when it was issued; the database confirms status now.

The official verification route is the GOTS public database, at global-standard.org. Check it directly rather than relying on a copy, and treat any mismatch between a certificate and the record as a question to ask rather than a conclusion to draw.
