A chemical substance inventory is a country’s official list of substances that can be manufactured or imported without new-substance registration or notification. If you export a raw material or mixture, every component, identified by its CAS number, must be on the destination country’s inventory or be notified.
Main inventories by country
| Country or region | Inventory or law |
|---|---|
| European Union | REACH (registered substances); formerly EINECS, ELINCS and NLP |
| United Kingdom | UK REACH |
| United States | TSCA Inventory |
| Canada | DSL and NDSL |
| Mexico | INSQ |
| China | IECSC |
| South Korea | KECI (K-REACH) |
| Japan | ENCS |
| Taiwan | TCSI |
| Australia | AICIS |
| New Zealand | NZIoC |
| Philippines | PICCS |
| Thailand | TECI |
| Vietnam | National chemical inventory |
| Russia and EAEU | TR EAEU 041/2017 |
| Turkey | KKDIK |
Some countries, such as Brazil, Colombia and Chile, are developing their own inventories.
Why keep them up to date
Inventories change: substances are added, new versions are published and related restrictions appear. Checking hundreds of raw materials across several markets by hand isn’t feasible, and one mistake can block a shipment at customs.
Benefits of country-level control
- Know before you sell whether a product can enter a market.
- Answer exporting customers quickly.
- Spot substances that need notification or substitution in time.
How Kemchain helps
The Compliance Checker in Kemchain Suppliers matches each raw material’s composition, by CAS, against the inventories of the markets you choose (REACH, TSCA, IECSC, KECI, DSL, NDSL, AICIS, TCSI, PICCS, NZIoC, INSQ, Vietnam, Thailand, EAEU…) and alerts you when something changes.
