Research findings
Comparative structure study
The largest recorded reporting jurisdiction, Jiangsu, contains 6 records (20.0% of this 30-record cohort). The remaining cohort contains 24 records. The comparison concerns archive composition.
The recorded industry label Advanced chemicals accounts for 46.7% here (14/30), compared with 1.4% in the parent set (269/19,297), an absolute gap of 45.3 percentage points.
17/30 companies link to pages with existing source-supported excerpts (56.7% of the cohort). The other 13 records remain usable for archive composition, but do not support new operating case studies.

Ratio of label participation, not market share; multi-label counts overlap.
Excluding this cohort, the recorded industry label Advanced chemicals covers 255/19,267 remaining records (1.3%), an absolute gap of 45.3 percentage points from this cohort.
Concentration and cross-sectional structure
The full reporting jurisdiction distribution has 17 labels; the top 3 contain 13/30 records (43.3%).Other known labels contain 17 records.
For 30 records with known labels, the effective category count is 10.7, versus 17 actual labels. Definitions and scope are in the methodology.
The table shows ten labels; 7 others are included in the calculations above.

Non-empty fields are not necessarily accurate or supported by originals.
| Scope of source support | Count |
|---|---|
| Profiles with source-supported excerpts | 17 |
| Distinct corresponding companies | 17 |
| Reviewed Chinese/English paragraph pairs | 18 |
Counts concern existing reviewed bilingual excerpts, not re-certification of originals or entire reports.
| Transparent rule reminder | Records | Cohort share |
|---|---|---|
| Contains registration-narrative wording | 1 | 3.3% |
A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
| Matched field | Candidates | Cohort share |
|---|---|---|
| Company name | 2 | 6.7% |
| Recorded products | 30 | 100.0% |
| Sub-industry | 1 | 3.3% |
An ID may match several fields, so counts may exceed the cohort total. Matches establish search relevance only.
Among the translated non-broad query terms, “industrial gases” has the most matches: 17/30. Name, product and sub-industry fields match 0, 17 and 1 records respectively; the largest field is product field. Fields can overlap, and a term remains a search link rather than verified business activity.
| Selected query term | Candidates/share | Name matches | Product field | Sub-industry |
|---|---|---|---|---|
| industrial gases | 17 · 56.7% | 0 | 17 | 1 |
Selected broad terms and specific segment terms, not the full query. Terms and fields can overlap and must not be summed. Counts show lexical sensitivity; no records are removed without primary evidence.
Intersection with 2026 local lists
12 of this cohort’s 30 records link through existing company-ID mappings to 2026 lists from all jurisdictions (40.0%). This intersection measures list linkage, not successful recognition or company growth.
| Observation set | List records | New-applicant records | Review records | Mapped company IDs |
|---|---|---|---|---|
| National list records linked to this cohort’s IDs | 12 | 0 | 12 | 12 |
List rows and company IDs are separate counts, not new firms or final recognition.

Separate material leads by application validation
The Electronic chemicals label covers 1 records (3.3% of this cohort). This archive clue raises a verification question about Use-specific electronic chemicals or supporting materials with validation documents; it does not establish that these companies already deliver it.
