ZDHC is relaunching the ZDHC Gateway, taking the platform offline for a one-time transition window. This article explains what's changing, what you need to do to prepare, and what to expect before, during, and after the transition.
What is happening?
ZDHC is relaunching the ZDHC Gateway. To migrate data and complete system checks, ZDHC will take the current Gateway fully offline for a one-time transition window from 7–17 August 2026. The relaunched Gateway goes live on 18 August 2026.
No . Your CleanChain account, data, and supplier connections remain fully accessible throughout the transition. Only functions that depend on the ZDHC Gateway itself — most notably generating an InCheck report — are unavailable while the Gateway is offline. This is a ZDHC-managed migration and is outside CleanChain's control.
What do I need to do before 7 August?
What can't I do during this period?
You will not be able to access the ZDHC Gateway or generate InCheck reports during this window. No Gateway access, data review, submission, or reporting is possible until the relaunch is complete. You can still access your existing InCheck reports via CleanChain during this time.
Everything else. You can log in as normal, view and download your InCheck reports and CIL data from completed InCheck reports, download or view technical reports, manage your supplier network, review existing records, and use CleanChain's other compliance tools.
Will my ZDHC Gateway data be lost?
No . ZDHC has confirmed that all data — organisation and user information, active subscriptions, products, certifications, InCheck data, and ClearStream data (from 2022 onward) — will migrate automatically to the relaunched Gateway. You do not need to re-enter or re-upload anything, with one exception: any organisation or user invitations that haven't yet been activated will need to be reissued after the relaunch.
No . Old AIDs and UIDs are not carried over — ZDHC Gateway accounts will receive a new account ID, and the same applies to UIDs. If you've referenced your ZDHC Gateway AID elsewhere, you'll need to update it yourself once your new AID is issued.
Yes. After relaunch of Gateway, users will now have to perform one additional step on the Gateway after they submit CIL via CleanChain. More information on the process can be found here. The CIL upload function remains the same.
Yes - no change to the Product Library.
From 25 August 2026, 8:00 AM CEST, once InCheck generation resumes on CleanChain.
ZDHC has acknowledged the transition and temporarily extended the 42-day reporting window to 90 days for July InCheck reports.
Yes, you can currently search ZDHC Gateway Products using PID on the CleanChain product library. Starting 17 August 2026, ZDHC will introduce new Product Reference IDs, and you'll be able to search using either PID or the new Product Reference ID. ZDHC has confirmed that old PIDs (issued by the previous Gateway) will remain valid for some time after the relaunch, though they will eventually be phased out and hidden.
