How does the new ZDHC InCheck workflow work? What suppliers need to know.
The ZDHC Gateway has changed, and with it comes an updated ZDHC Incheck workflow for how facilities manage and publish their monthly ZDHC Performance InCheck Reports.
For suppliers, the key change is simple: your connected Solution Provider now plays a central role in getting your chemical inventory data into the ZDHC Gateway.
Understanding the new process and keeping your chemical inventory ready throughout the month can help make Performance InCheck reporting more efficient.
What Has Changed with ZDHC Performance InCheck?
Under the new ZDHC Incheck workflow, facilities do not manually enter their chemical inventory data directly into the Gateway to create a Performance InCheck Report.
Instead, a facility’s connected Solution Provider submits the InCheck Report based on the chemical inventory information managed through its solution.
Each report represents a single calendar month and contains information about the chemical formulations used by the facility during that reporting period, together with relevant ZDHC MRSL information.
This makes the relationship between your day-to-day chemical inventory management and your monthly InCheck reporting increasingly important.
How Does the New ZDHC InCheck Workflow Work?
The process can be viewed as a connected chemical data journey:
SDS → Chemical Inventory → CIL → InCheck → ZDHC Gateway
Each stage contributes to the quality and efficiency of the next.
1. Safety Data Sheets
Your Safety Data Sheets provide important information about the chemical formulations used at your facility.
Keeping SDS information current and organised provides a stronger foundation for chemical inventory management and reporting.
2. Chemical Inventory
Your chemical inventory records the formulations being used or delivered at your facility.
Maintaining this information throughout the month can reduce the amount of work required when it is time to prepare your monthly Performance InCheck Report.
3. Chemical Inventory List
Structured chemical inventory data can be used to support the creation of a Chemical Inventory List (CIL), helping facilities organise chemical information and monitor ZDHC MRSL conformance.
4. Performance InCheck
Your monthly chemical inventory data is used to prepare the Performance InCheck Report, providing visibility into the ZDHC MRSL conformance of the chemical products in your inventory.
5. ZDHC Gateway
Your connected Solution Provider submits the Performance InCheck Report to the ZDHC Gateway, where the facility completes the required publication process.
The result is a much clearer relationship between the chemical data you manage throughout the month and the InCheck Report ultimately available through the Gateway.
What Do Suppliers Need to Know About Monthly Reporting?
Performance InCheck reporting is based on a calendar-month chemical inventory.
Your Solution Provider has a defined period following the end of the reporting month in which to submit the report to the ZDHC Gateway. During the 2026 platform transition, suppliers should pay particular attention to the applicable submission timelines and Gateway guidance.
Each submission also identifies the Inventory Type, such as Usage or Delivery, helping distinguish how the facility’s chemical inventory for that reporting period has been recorded.
This makes consistent monthly chemical inventory management increasingly important.
Rather than waiting until reporting time to assemble information, facilities can benefit from maintaining accurate chemical and SDS data throughout the reporting period.
What If You Have More Than One Connected Solution Provider?
Facilities may have more than one connected Solution Provider, but only one Performance InCheck Report for a facility and reporting month can ultimately be published and shared through the ZDHC Gateway.
This makes understanding your Solution Provider relationships important.
Where multiple reports are submitted for the same facility and reporting month, the facility may need to determine which report is published according to the applicable Gateway process.
Suppliers should therefore understand:
- Which Solution Providers are connected to their facility
- Which provider is submitting their Performance InCheck data
- Whether the chemical inventory used for the report is complete and current
- The status of the submitted report
- Any action required within the ZDHC Gateway
The Solution Provider relationship is no longer simply about producing a report. It is part of the wider chemical data and the new ZDHC Incheck workflow.
Why Chemical Inventory Readiness Matters
A Performance InCheck Report is only one output of a much broader chemical management process.
If SDS information is missing, chemical inventories are outdated or chemical information is maintained across disconnected spreadsheets and systems, preparing monthly reporting can require additional manual work.
A more proactive approach is to keep the underlying chemical information organised throughout the month.
This means maintaining:
Current SDS information → Accurate chemical inventory → Structured CIL data → MRSL visibility → InCheck readiness
The objective should be to make monthly reporting an output of good chemical management, rather than a separate exercise that starts again every reporting cycle.
How CleanChain Supports the New ZDHC InCheck Workflow
CleanChain provides a connected chemical management environment that helps suppliers manage the information behind their ZDHC reporting.
Rather than treating SDS management, chemical inventory, CIL and Performance InCheck as separate activities, CleanChain helps bring these processes together.
SDS Management
Upload and centralise Safety Data Sheets from suppliers and facilities. CleanChain’s AI-powered SDS technology can extract key chemical information from SDS documents, helping reduce manual data entry and create more structured chemical data.
Chemical Inventory Management
Maintain chemical inventory information in one centralised environment, improving visibility across the chemicals being used within your facility.
CIL Support
Use structured chemical and SDS information to support Chemical Inventory List creation and reduce repetitive manual data preparation.
ZDHC MRSL Visibility
Monitor chemical formulations and available ZDHC MRSL conformance information to better understand your chemical inventory.
Performance InCheck
Use your chemical inventory data to support monthly Performance InCheck reporting through CleanChain as your connected Solution Provider.
ZDHC Gateway
Move from day-to-day chemical management to ZDHC reporting through a more connected workflow.
SDS → Inventory → CIL → InCheck → ZDHC Gateway
The result is less reliance on fragmented information and a clearer path from the chemical data managed at your facility to your monthly ZDHC reporting.
What Should Suppliers Do Now?
If your facility uses Performance InCheck, now is a good time to review your chemical management and reporting process.
Start by confirming your connected Solution Provider and understanding who is responsible for submitting your monthly InCheck data.
Then review whether your chemical inventory is current, whether the necessary Safety Data Sheets are available and up to date, and whether your team understands the monthly reporting and Gateway publication process.
Most importantly, consider whether your current workflow makes reporting easier or whether your team is still spending significant time gathering, checking and rebuilding chemical information every month.
Make Your New ZDHC InCheck Workflow Easier
The changes to the ZDHC Gateway make connected, well-managed chemical data more important than ever.
CleanChain helps suppliers move from managing individual documents and reporting requirements toward a connected chemical management workflow.
From SDS to ZDHC Gateway, simplify every step with CleanChain
Centralise your chemical information, improve inventory visibility and create a more efficient path to monthly Performance InCheck reporting.
