Overview of Textile Restricted Substances Testing

Tested by: NABL-accredited partner lab
Regulation: REACH, brand RSLs & ZDHC
Typical turnaround: 5–7 working days
Sample needed: 1 m fabric or 2 garments

Export markets restrict chemicals in textiles and leather that touch the skin. Under the EU’s REACH regulation, azo dyes that release listed carcinogenic amines, nonylphenol ethoxylates, chromium VI in leather and many others are restricted, and global brands go further with their restricted substances lists (RSLs) and the ZDHC Manufacturing RSL for chemicals used in the factory.

Tests cover the finished product: azo amines, free formaldehyde, pH, extractable heavy metals, APEOs, phthalates in prints, chlorophenols, chromium VI and, increasingly, PFAS in water-repellent finishes. Children’s wear and baby textiles have the strictest limits.

Frequently asked questions

Do I need to test every colour?

Usually each colourway is tested, because dyes differ. Brands sometimes allow similar shades from the same dye family to be grouped; check your buyer’s rules.

Which standard is the product tested against?

The Indian Standard, international standard or buyer specification that applies to your product and market. We confirm it with you before testing, and the report states the method used for each parameter.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
