Resources for Chemical Professionals

Chemical identifier references, regulatory guides, external databases, formulation knowledge, and supplier documents β€” in one place.

Quick Reference

Chemical Identifiers

Four identifiers every sourcing professional needs to know β€” and when to use each one.

CAS Number

A unique numerical identifier assigned by the Chemical Abstracts Service to every chemical substance. Format: NNNNNN-NN-N (e.g. Glycerin = 56-81-5).

When to use: Universal identification across suppliers, regulatory filings, and databases. Use in RFQs and purchase orders to eliminate name ambiguity.

Example: Phenoxyethanol β†’ 122-99-6

INCI Name

International Nomenclature of Cosmetic Ingredients β€” standardised names used on cosmetic ingredient labels in the EU, US, and most markets.

When to use: Required on cosmetic product labels (EU Regulation 1223/2009, US FDA). Use in formulation documentation and labelling.

Example: Glycerin β†’ INCI: Glycerin (same here, but many differ)

EC Number

European Community number β€” assigned by ECHA to substances in the EINECS, ELINCS, or NLP inventories. Format: NNN-NNN-N.

When to use: Required for REACH compliance filings and SDS documentation in the EU. Look up via ECHA's Chemical Inventory.

Example: Glycerin β†’ EC 200-289-5

HS Code

Harmonised System code β€” a 6-digit international customs classification for goods. Extended to 8–10 digits by country.

When to use: Required on customs declarations, import/export documentation. Determines applicable tariff rates and import duties.

Example: Glycerin β†’ HS 2905.45 (pharmaceutical grade)
