ZDHC MRSL Chemical Gateway Services


The industry focus is slowly moving towards the use of cleaner ‘inputs’ rather than treating the finished articles. Brands, Retailers and other stakeholders are expecting chemical suppliers to manufacture cleaner chemicals.

The ZDHC group of Brands have launched the ZDHC MRSL or the Manufacturing restricted substances list. This list comprises restricted chemicals which cannot be detected in the input chemical used during manufacturing.

With this now, several chemical manufacturers and suppliers need to test their raw materials and final chemicals in order to ensure that they comply with the MRSL limits. This data can then be uploaded on the ZDHC CHEMICAL GATEWAY.

Testing of restricted substances in input chemicals is a specialized task due to the complexity of chemicals used by the industry. NimkarTek Laboratory has specialists who have expert understanding of the Textiles and Leather industry. Using our ‘Smart Testing’ approach, we are in a unique position to test your chemicals and identify compounds that are likely to cause non-compliances with a reduction in testing costs.

We are very proud to inform you that NimkarTek Laboratory is recognised and approved by ZDHC as an indicator for Level 1 conformance to the ZDHC MRSL in connection with the ZDHC Chemical Gateway.

How does it work?

  • NimkarTek will test chemicals / formulations for the ZDHC MRSL Criteria
  • A Test Report will be issued to the Chemical Supplier on completion of the analysis
  • If the chemical /formulation conforms to the ZDHC MRSL, NimkarTek will send the test report to ZDHC.
  • The chemical suppliers can upload NimkarTek Test reports on the Chemical Gateway.

Our chemical tests include the following :

  • Alkylphenol (AP) and Alkylphenol Ethoxylates (APEOs)
  • Chlorobenzenes and Chlorotoluenes (COC)
  • Chlorophenols (All Isomers)
  • Banned Amines from Azo Dyes
  • Carcinogenic Dyes
  • Allergenic Disperse Dyes
  • Flame Retardants
  • Glycols
  • Halogenated Solvents
  • Organotin Compounds
  • Polycyclic Aromatic Hydrocarbons (PAHs)
  • Perfluorinated and Polyfluorinated Chemicals (PFOS and PFOA)
  • Phthalates
  • Total Heavy Metals
  • Volatile Organic Compounds (VOC)
  • Short Chain Chlorinated Paraffin (SCCP)
