Achieve ZDHC Conformance Level 1 to 3 through the c-MAP Programme

Chemical companies around the world will benefit from becoming Chem-MAP® certified through the c-MAP Programme. Completion of the c-MAP programme enables chemical manufacturers to gain ZDHC Conformance Level 1 to 3, providing verification of chemical formulations to the ZDHC MRSL. Thereby, demonstrating their commitment to responsible upstream chemical management.

Benefits of c-MAP for Chemical Manufacturers

  • ZDHC conformance to Level 1 to 3
  • ZDHC compliant chemical formulations listed on the ZDHC Gateway updated to show certification of ZDHC Conformance Level 1 to 3
  • Assurance of chemical supply chain transparency through on-site audits and MRSL testing (ZDHC conformance Level 3 only)
  • Recognition of the chemical company’s commitment to responsible chemistry

Becoming a ZDHC Certified Chemical Manufacturer

The journey to ZDHC conformance begins with the chemical manufacturer uploading their product portfolio onto the ZDHC Gateway. This process is effectively the chemical company’s self-declaration, that their Gateway listed products are conformant to the limits specified in the ZDHC MRSL, entitling them to achieve Level 0 ZDHC conformance for a limited time period.

In order to achieve a higher level of ZDHC conformance, chemical manufacturers are required to engage with a ZDHC Accepted Certification Standard, such as Chem-MAP®.

The c-MAP programme is a Chem-MAP® product which enables chemical manufacturers to become ZDHC certified, to Level 1 and Level 3.

How to become certified through the c-MAP programme

Chemical companies who engage in the c-MAP programme, with the aim of achieving ZDHC conformance for their products, are required to undertake the appropriate c-MAP module(s) to achieve their desired level of conformance:


To achieve ZDHC Conformance Level 1

Your business will need to complete:

  • c-MAP Module 1: c-MAP MRSL Testing

To achieve ZDHC Conformance Level 3

Your business will need to complete:

  • c-MAP Module 1: c-MAP MRSL Testing
  • c-MAP Module 2: c-MAP On-site Chemical Management Audit
  • c-MAP Module 3: c-MAP Chemical Supply Chain Transparency


c-MAP Programme Modules

The c-MAP programme evaluates a chemical supplier’s readiness to supply MRSL compliant chemicals to their customers. The c-MAP assessment involves both the testing of chemical formulations and site audits, which also evaluate the management of suppliers.

To start your c-MAP journey to ZDHC conformance, contact a chemical management expert in the Chem-MAP® Team:

Module 1: c-MAP MRSL Testing

Mandatory for both ZDHC Conformance Level 1 and Level 3

In order to achieve a higher level of ZDHC conformance, an intelligent product selection of a company’s uploaded ZDHC Gateway listed product portfolio will need to be tested against the ZDHC MRSL. The c-MAP MRSL testing module is divided into two parts:


Complete MRSL Testing of Chemical Formulations

A proportion (5%*) of the listed ZDHC Gateway chemical formulations will undergo testing against ALL of the chemicals listed in the ZDHC MRSL (over 140 individual chemical tests)

Smart Testing of Chemical Formulations

A proportion (10%*) of the ZDHC Gateway listed chemicals will undergo ‘Smart Testing’ against the ZDHC MRSL chemical groups according to risk matrices. ‘Smart Testing’ uses testing principles which are based upon the guidelines published by ZDHC (Annex A – Quality Control Guidance for Analytical Test Data Supporting ZDHC MRSL Conformance).


  * Please note that percentages are based upon the percentages of products intended to be uploaded onto the ZDHC Gateway. These numbers are subject to change, depending on the minimum number of products uploaded and level of risk assigned.

The c-MAP MRSL testing module relies on the chemical testing of multiple batches of the same chemical products, to investigate the consistence of the chemical product supplied. The formulations are required to pass the c-MAP MRSL testing requirements, in order to achieve ZDHC conformance Level 1.

In order to extend the ZDHC conformance achievement to Level 3, c-MAP Modules 2 and 3 are also required.

All c-MAP MRSL testing is carried out within the analytical laboratory at Eurofins | BLC Leather Technology Centre Ltd., based in the UK.

Module 2: c-MAP On-Site Chemical Management Audit

Mandatory for ZDHC Conformance Level 3

The c-MAP Chemical Management Audit module involves an on-site audit of a chemical manufacturing facility (multiple site audits are also available). Within the c-MAP Chemical Management Audit, the product stewardship practices of the chemical supplier are evaluated. There are six critical areas covered within the audit protocol, these include:

  • Management Controls
  • Chemical Selection and Assessment
  • Chemical Storage
  • Chemical Use
  • Chemical Disposal
  • Chemical Distribution

Module 3: c-MAP Chemical Supply Chain Transparency

Mandatory for ZDHC Conformance Level 3

The c-MAP Supply Chain Transparency module is a verification process used to evaluate the supply chain of the chemical manufacturer, focusing on supplier and subcontractor management processes.

The c-MAP Module 3 can be subdivided into two parts:

On-site Assessment:

  • Used to assess the chemical manufacturers supply chain, this includes subcontracted activities which are likely to incur additional chemical risk
  • The c-MAP Module 3 assessment is carried out alongside the c-MAP Chemical Management Audit (Module 2)

Testing of Raw Materials:

  • A percentage of the raw materials (used in the formulation of commercial chemical products) are subjected to the Eurofins | BLC Due Diligence Testing Standard (MRSL testing)

c-MAP for Multiple Chemical Sites

c-MAP can be extended within the applicant company to include additional chemical production sites. Assessment of multiple sites is viewed positively, as it further supports improved management of chemical risk. c-MAP assessments for multiple sites are further recognised in the overall c-MAP Programme awards system.

c-MAP Awards

  • Credits are awarded for each of the three c-MAP modules, Modules 1, 2 and 3
  • For each module a maximum of 100 credits can be awarded
  • Upon completion of the full c-MAP Programme credits are combined to provide an overall Grade for the facility:
Site Award Credits
Grade A 250 credits*
Grade B 225 credits*
Grade C 200 credits*
Grade D 150 credits*

* Minimum requirement

In the case of multi-site audits of chemical manufacturing facilities, additional company awards are obtainable:

Chem-MAP® Multi-site Award

On the completion of two or more chemical management audits, chemical manufacturers are eligible to achieve Chem-MAP® Multi-site Award status, dependent on the grades awarded for individual site audits:

Company Awards (Multiple Sites) Grades
Leader Achievement of “Grade A” at the main production site and at least “Grade B” for all other major production sites
Advanced Achievement of “Grade B” at the main production site and at least “Grade C” for all other major production sites
Progressive Achievement of “Grade C” at the main production site and at least “Grade D” for all other major production sites
Engaged For manufacturers engaged in the c-MAP process


c-MAP recertification will be required after 2 years.
