What is the Service Program?

ZDHC Verified InCheck Level 1 is a program that verifies the credibility of a supplier’s submitted Performance InCheck reports via an on-site assessment. It uses a spot-check protocol to randomly verify the chemical inventory on-site, assessing how closely the uploaded chemical list matches actual inventory at the facility.  If the verification succeeds, the supplier receives a “Verified InCheck Level 1 check mark” on their profile, which connected brands can see.  This verification is recommended annually, and the check mark remains visible for 12 months.

Certification Process

  1. Preparing a Performance InCheck Report

    Companies must submit at least three consecutive Performance InCheck reports for the same inventory type.

  2. Selecting and Contracting a Verification Body

    Select a ZDHC-approved InCheck Verification Body (RST) and confirm the on-site verification schedule.

  3. Pre-Verification Documentation

    Submit required documentation, including process diagrams, chemical storage layouts, SDSs, purchase orders, and chemical inventory lists.

  4. Score Calculation and Results Evaluation

    A score of 80% or higher for the combined score of the spot-check parameters is considered PASS. Any score below 80% is considered FAIL.

  5. Result Reporting and Checkmark Assignment

    If the requirements are met, a checkmark is assigned to the ZDHC Gateway, allowing brands and stakeholders to confirm verification completion. If the verification fails, re-verification is possible by resubmitting three new Performance InCheck reports.

    The Verified InCheck Level 1 checkmark is valid for 12 months, after which the verification process must be repeated.
