European buyers of polymer additives continue to operate under one of the world's most demanding regulatory frameworks. As of 2026, three practical questions determine whether a supplier relationship runs smoothly or stalls at customs: registration status, SVHC content and documentation quality.

Registration Status: Ask for Numbers, Not Adjectives

All core Aolong photoinitiators, HALS and UV absorbers that are subject to REACH registration are either fully registered or pre-registered through our EU Only Representative arrangement. Buyers should always ask for the registration number and tonnage band rather than accepting a generic 'REACH compliant' statement.

SVHC Screening: Two Families to Watch

  • UV-328 remains on the Authorisation List (Annex XIV), which is why Aolong positions it exclusively for non-EU markets and recommends UV-326 or UV-329 for European customer applications.
  • Chlorinated phosphates such as TCPP are under ECHA evaluation; we provide the latest assessment status with each quotation so formulators can make informed choices.

Documentation: Where Exports Fail in Practice

Every Aolong shipment for the EU includes:

  • Batch-specific COA with HPLC purity
  • GHS-aligned SDS in the destination language
  • Transport classification under ADR/IMDG where applicable
  • Halogen-content declarations for flame retardants bound for electronics customers

Our regulatory team monitors ECHA updates quarterly and notifies affected customers within two weeks of any list change touching their products. If you would like a compliance dossier for any Aolong grade, contact info@aolongchemical.com — the package typically arrives within three working days.
