Please note that these lists as add-on lists. Please contact your account manager (or support@intersolia.com) if you are interested in the lists.
The lists will be shown in the Overview in iChemistry and they are described below.
If you have products on any of the list, you'll need to determine if you should substitute the product or in any way adapt your risk assessment. As a first step, you can check the concentration level of the substance that is causing the match. This way you'll get an understanding if the hazardous substance constitutes a significant or minor part of your chemical product.
To identify the substance, you can visit the product's iSafe and find the substance under Restriction- and prohibition lists, under Reason. Then check the Safety Data Sheet (SDS) Section 3 or click on 'Show composition' at the bottom of iSafe to see the concentration of that substance in the chemical product.
If you are unsure about how to proceed, we recommend that you contact either your account manager or our EHS experts by emailing consulting@intersolia.com, and they will guide you further.
TSCA Inventory
The TSCA Inventory list (Toxic Substances Control Act) contains regulated chemical substances in the US, identified by a CAS number. This list contains only the substances that have some commentary written under section FL (Substances with some EPA TSCA Regulatory Flag).
TSCA Flags in iChemistry - How Screening and Interpretation Work
Overview
iChemistry uses the TSCA Inventory as part of its screening process. Hits in the system are based on so-called “flags” assigned to substances in the TSCA list.
It is important to understand that this screening is only an initial step and does not constitute a final regulatory assessment.
How the screening works
- iChemistry matches substances against the TSCA Inventory
- Only substances with an assigned flag are included in the results list
- The flag is a coded value in the “FLAG” field in the TSCA Inventory
- These codes represent different regulatory requirements or restrictions
A hit therefore indicates that a substance is subject to some form of regulatory control—it does not necessarily mean that the substance is prohibited or directly restricted.
What do the flags mean?
The flags in the TSCA Inventory are short codes indicating the type of regulatory requirements applicable to a substance.

Workflow after a match
When a substance generates a hit in iChemistry, the following steps should be performed:
1. Confirm the match
2. Verify that the substance appears in the iChemistry results
3. Retrieve TSCA data
4. Download the full TSCA list with flags:
https://www.epa.gov/tsca-inventory/how-access-tsca-inventory#download
5. Verify the flag
Locate the substance and identify its flag value
6. Interpret the flag
Review what the flag represents and determine its regulatory implications
This approach is comparable to interpreting entries in REACH Annex XVII, where a hit requires further analysis.
Common Flags and Their Meaning
The following flags are particularly relevant for customer inquiries:
R
Section 6 “Hazardous Chemicals Control Rules”
Section 6(h) (PBT substances)
S / SP
SNUR (Significant New Use Rules)
Summary
- iChemistry provides an initial screening based on TSCA flags
- A hit indicates that a substance has a regulatory designation
- Further analysis is required to understand the reason
- The final assessment depends on interpreting the flag in the TSCA Inventory
California Proposition 65
Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986. The list is matched against CAS no for substances in your chemical products. Proposition 65 list is collected from official OEHHA web page.
