所有計劃用于加工 GOTS 產品的化學品投入物，使用前都必須通過 GOTS 被授權認證機構的審批。配制品使用前必須通過 IWG授權有以下特定認可范圍的 GOTS 被授權認證機構的評估且其批準清單中必須有其注冊的商品名：
- Approval of textile auxiliary agents (chemical inputs) on positive lists
紡織助劑（化學品投入物）肯定列表的審批
Approval must be applied by the applicable chemical producer or supplier of the preparations who receive conformity documents(Letters of Approval) issued by the authorised certifiers and containing the trade names of applied preparations that have been found to be compliant with the criteria of this Standard.
配制品的審批必須由其相關化學品生產商或供應商提出申請，主管認證機構會就評估后符合本標準的相關配制品向其生產商或供應商頒發合格文件（批文），并且批文上有該相關配制品的商品名。
For all chemical inputs (substances and preparations) a Material Safety Data Sheet (MSDS), prepared according to an applicable recognised norm or directive must be available. The Approved Certifiers are requested, wher appropriate and felt necessary, to include further sources of information (such as additional toxicological and environmental data on specific components of the auxiliary agents, test reports, independent lab analysis and traceability checks of ingredients) in the assessment.
所有化學品投入物（物質和配制品）必須有根據適用的公認標準或規范編制的物質安全數據表（MSDS）。適用時及必要時，將要求被授權認證機構進一步評估信息來源（諸如：助劑中其它特定成分的毒理和環境數據、測試報告、獨立實驗室對成分的分析及追溯核查）。
Certified Entities must have copies of valid Letters of Approval on hand listing all preparations they are using in processing and manufacturing GOTS Goods as verification proof that all colourants and textile auxiliaries used for GOTS Goods are actually approved.
被認證實體必須持列有其在加工或制造GOTS產品時所用全部物料的有效許可證復印件，以證實所有用于GOTS產品的著色劑和助劑確實是被許可的。
