Organic content claim
Also searched as: organic claim, Organic Content Standard, OCS, OCS 100, OCS Blended, certified organic cotton, organic fiber content
A statement that a product contains a stated share of organically grown fiber, usually supported by a chain-of-custody standard such as Textile Exchange's Organic Content Standard.
In detail
Organic status belongs to how a crop or animal was raised and is certified at the farm under a recognized organic regulation. After the fiber leaves the farm, a content claim depends on tracking that material through ginning, spinning, fabric production and garment assembly. Textile Exchange's Organic Content Standard (OCS) provides voluntary third-party certification of that chain of custody. It has two label grades: OCS 100 for products with at least 95 percent organic material, and OCS Blended for products with at least 5 percent, measured against the total product excluding accessories and trims.
The science and numbers
OCS certification applies to each site that handles the material, from the first processor through manufacturing, packaging, labeling, storage and shipping, up to the seller in the final business-to-business transaction. Farm certification sits outside OCS itself: the fiber must come from farms certified to recognized national organic standards, which in the United States means the USDA National Organic Program for agricultural production. The claim percentage is calculated by weight on the whole product minus accessories and trims. Laboratory screens for genetically modified cotton DNA or pesticide residues can flag problems, but no test can prove organic origin, so documentary evidence, including scope certificates, transaction certificates and audited volume reconciliation, carries the claim.
A practical example
A T-shirt fabric is 60 percent organic cotton and 40 percent conventional polyester. Under the OCS framework it could only carry the Blended grade, and the claim would state the organic percentage. A student evaluating the shirt should ask for the relevant certificates and transaction documentation, and should notice that the claim says nothing about how the fabric was dyed or finished.
What to distinguish
An organic content claim describes where the fiber came from, not the chemistry of processing or conditions in factories. OCS is a content and chain-of-custody standard; it is not designed to set criteria for dyes, finishes, wastewater or labor, whereas GOTS adds environmental and social criteria for processing. Organic farming also permits certain approved inputs, so organic does not mean that no substances were ever applied.
Origins and history
Textile Exchange, which began as Organic Exchange, developed the Organic Content Standard to give organic fiber claims a common chain-of-custody basis; the standard carries a 2013 copyright, and version 3.0 is dated 1 March 2020. Its two-grade structure, a near-complete grade and a blended grade with a low minimum, mirrors the approach of Textile Exchange's Recycled Claim Standard.
