An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.

Ratio of label participation, not market share; multi-label counts overlap.

Excluding this cohort, the recorded industry label Advanced materials covers 340/644 remaining records (52.8%), an absolute gap of 10.7 percentage points from this cohort.

The full industry distribution has 6 labels; the top 3 contain 91/96 records (94.8%).Other known labels contain 5 records.

For 96 records with known labels, the effective category count is 2.1, versus 6 actual labels. Definitions and scope are in the methodology.

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.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

22 of this cohort’s 96 records link through existing company-ID mappings to 2026 lists from all jurisdictions (22.9%). 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.

The 2025 macro context for Shandong uses a different denominator from this cohort.

Intermediates and high-purity products need scale-up checks

The General-purpose fine chemicals label covers 33 records (34.4% 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.
