This article provides an overview of the latest changes, fixes and new functionalities released in the ZDHC Gateway. Updates are organised by release date and cover both general platform changes and stakeholder-specific improvements.

01 September, 2026

Chemical Formulators

• Certification statuses on your products now correctly show "Expired" once they've lapsed.
• Technical Data Sheets (TDS) can now be added when creating or editing a product, and display properly.
• ChemCheck report downloads now have clearer file names, and all team members can download them (not just admin users).
• Fixed a subscription creation issue that could block you from subscribing.
• Your dashboard now clearly flags whether your subscription has expired or is missing.

Suppliers

• Invitation emails to your team and partner organisations are now more reliable.
• Team members can now remove themselves from your organisation.
• ClearStream: the testing laboratory name now shows directly in your reports and detail view; several reports that showed the wrong lab after migration have been corrected.
• InCheck: declining a submission now correctly frees up your slot to resubmit; several report display issues (contact info, product counts, reporting month) are fixed.

ZDHC Approved Wastewater Laboratories

• Your laboratory name now displays correctly across ClearStream reports (several previously migrated reports showed the wrong laboratory).
• CSV report uploads no longer fail due to formatting issues.
• ClearStream journeys no longer show steps as already completed or a laboratory as already selected before you've taken action.

Brands / Retailers

• Fixed a mismatch in Chemicals to Zero (CtZ) levels between ZDHC Gateway search results and ChemCheck reports, so the figures you see are consistent.
• Fixed inconsistent product counts and conformance data across regenerated InCheck reports.
