GOTS Scope 4: Chemical Inputs & Accessories Certification

The Global Organic Textile Standard (GOTS) is the world's leading processing standard for organic fibers, ensuring environmental and social responsibility throughout the entire supply chain. GOTS Scope 4 is the dedicated certification category for evaluating and approving chemical inputs—such as dyestuffs, textile auxiliaries, printing inks, and accessories—used in organic textile manufacturing.

ETKO provides independent verification for chemical manufacturers, formulators, and traders seeking GOTS Scope 4 approval, enabling seamless integration into the global sustainable textile supply chain.

What Does GOTS Scope 4 Cover?

GOTS Scope 4 certification assesses all chemical preparations and structural components applied in textile wet processing, dyeing, printing, and finishing stages:

• Dyestuffs & Pigments: Organic and inorganic colorants, dyes, and pigment formulations used in textile processing.

• Textile Auxiliaries: Wetting agents, softeners, enzymes, fixatives, sizing agents, and finishing auxiliaries.

• Printing Inks & Pastes: Digital textile inks, binders, and printing formulation components.

• Accessories: Buttons, zippers, sewing threads, linings, and trims evaluated against GOTS environmental criteria.

The GOTS Scope 4 Approval Process

Achieving a GOTS Letter of Approval (LoA) involves a rigorous multi-step evaluation:

1. Application & Product Inventory: Submission of full technical specifications and chemical inventory to be evaluated.

1. Document & SDS Review: In-depth technical review of Safety Data Sheets (SDS), Technical Data Sheets (TDS), and analytical test reports against GOTS toxicological and eco-criteria.

1. On-Site Facility Inspection: On-site audit evaluating chemical manufacturing practices, environmental management systems, wastewater treatment, and occupational health and safety (OHS).

1. Issuance of Letter of Approval (LoA): Compliant products receive an official GOTS Scope 4 Letter of Approval (LoA), valid for one year and registered on the GOTS approved chemical database.
