If GOTS/OCS certification starts post-harvest, what are the requirements for the raw fiber?

Raw natural fibers, such as cotton, wool, and flax certified to the National Organic Program (NOP) crop and livestock production standards may be used as raw materials for GOTS/OCS products. In fact, for textile products to be sold as “organic” in the United States, all fibers used must have been produced and certified under the NOP regulations.

For product sold in other countries, certification to any standard approved in the IFOAM Family of standards is accepted. (Most commonly: EC Regulation 834/2007, USDA’s NOP, APEDA’s NPOP.)
