Record counts do not rank supply capability or economic size.

Non-empty fields are not necessarily accurate or supported by originals.

Counts concern existing reviewed bilingual excerpts, not re-certification of originals or entire reports.

102 of this cohort’s 401 records link through existing company-ID mappings to 2026 lists from all jurisdictions (25.4%). This intersection measures list linkage, not successful recognition or company growth.

List rows and company IDs are separate counts, not new firms or final recognition.

Intermediates and high-purity products need scale-up checks

The General-purpose fine chemicals label covers 89 records (22.2% of this cohort). This archive clue raises a verification question about Defined chemicals with process and pilot documents; it does not establish that these companies already deliver it.
