Dataset description

Тhe European Customs Inventory of Chemical Substances is an information tool which allows users to: - clearly and easily identify chemicals; - classify them correctly and easily in the Combined Nomenclature; - name them in all EU languages for regulation purposes. Each product listed in ECICS is identified by the CUS number. Products are also identified by the Chemical Abstracts Service Registry Number (CAS RN), a system used to identify chemical products the world over. Names are usually recognised internationally like International Nonproprietary Names for pharmaceuticals, International Organization for Standardization names for pesticides and chemical names constructed according to the International Union of Pure and Applied Chemistry (IUPAC) nomenclatures. ECICS lists chemical names in a number of EU languages (currently mainly eleven) along with their tariff classification in the European Community's Combined Nomenclature (eight-digit CN codes). You will find a database to identify chemicals, classify them correctly in the combined nomenclature and name them in all EU languages for regulation purposes.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
