Organic cotton is one of the fastest-growing claims in apparel. Consumer demand for organic products has increased significantly, and brands across the market — from premium DTC labels to high-street retailers — are adding organic cotton lines. But what does "organic cotton" actually mean, how is it verified, and what do you need from your manufacturer to make the claim legally?

What is Organic Cotton?

Organic cotton is cotton grown without synthetic pesticides, herbicides or fertilisers, using farming methods that maintain soil health and biodiversity. Organic cotton farming is regulated by national and international standards — in the EU by EU Organic Regulation, in the US by NOP (National Organic Program).

Conventional cotton is one of the world's most chemically intensive crops. It uses approximately 16% of the world's insecticides despite covering only 2.5% of cultivated land. Organic cotton eliminates these chemicals — better for farmers, better for soil and better for waterways near growing regions.

What Organic Cotton Does Not Mean

Growing organic cotton is only the first step. The cotton fibre then goes through ginning, spinning, knitting or weaving, dyeing, finishing and garment production — any of which can introduce chemicals that undermine the "organic" positioning of the final product.

This is why simply using organically grown cotton does not make a finished garment "organic" in a meaningful, verifiable sense. To make a credible organic claim, the entire production chain needs to be certified.

GOTS: The Gold Standard for Organic Textiles

GOTS — Global Organic Textile Standard — is the world's leading processing standard for organic textiles. GOTS requires: a minimum of 70% certified organic fibre in the finished product, prohibition of 100+ hazardous chemicals in processing, mandatory wastewater treatment at all production facilities, and social compliance criteria across the supply chain.

A GOTS-certified garment means the organic certification has been independently verified from fibre to finished product. This is the only standard that enables a brand to make a fully substantiated "organic" product claim.

Without GOTS certification from your manufacturer, an "organic cotton" claim on your product is unverified and legally exposed under UK and EU green claims regulations.

OCS: For Blended and Partial Organic Products

The Organic Content Standard (OCS), managed by Textile Exchange, is used for products where not all content is organic — blended fabrics (organic cotton / polyester mix) or products with partial organic content. OCS verifies the traceability and percentage of organic material in the final product without the full GOTS environmental and social requirements.

OCS is the appropriate certification for claims like "contains 50% organic cotton" on a blended product. GOTS is required for claims like "100% organic cotton" or "made with organic cotton" without qualification.

Price Difference: Organic vs Conventional Cotton

Organic cotton typically costs 20–40% more than equivalent conventional cotton. The premium reflects lower yields in organic farming, higher certification costs throughout the supply chain and lower volume of supply relative to demand. For a finished garment, the fabric cost increase translates to a smaller percentage uplift in the final unit price — typically 10–20% higher for an organic cotton t-shirt versus a conventional equivalent at the same GSM.
