Seals Rubber Products Keyword Candidate Study

Comparative structure study

The largest recorded reporting jurisdiction, Shandong, contains 13 records (16.5% of this 79-record cohort). The remaining cohort contains 66 records. The comparison concerns archive composition.

The recorded chain role label Fine chemicals / Basic and process materials accounts for 30.4% here (24/79), compared with 3.8% in the parent set (740/19,297), an absolute gap of 26.5 percentage points.

26/79 companies link to pages with existing source-supported excerpts (32.9% of the cohort). The other 53 records remain usable for archive composition, but do not support new operating case studies.

6 keyword candidates match only a company name, with no matching term in recorded products or sub-industry fields. Product evidence is needed before treating these as operating businesses in this segment.

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

The parent set, All public archive records, contains 19,297 records. This cohort contributes 79 (0.4%); 19,218 records remain after excluding it.

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

Excluding this cohort, the recorded chain role label Fine chemicals / Basic and process materials covers 716/19,218 remaining records (3.7%), an absolute gap of 26.7 percentage points from this cohort.

The full reporting jurisdiction distribution has 18 labels; the top 3 contain 33/79 records (41.8%).Other known labels contain 46 records.

For 79 records with known labels, the effective category count is 10.7, versus 18 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 8 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Ningbo × Advanced equipment, contains 7 records, or 70.0% of the 10 records carrying the Ningbo label.

A cell contains company IDs carrying both labels. It does not establish procurement, supply or investment relationships between firms. Multi-label cells may overlap.

This page displays 8 of the full cross-tab’s 39 non-empty cells; the other 31 remain in the analysis.

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.

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, “sealing materials” has the most matches: 39/79. Name, product and sub-industry fields match 5, 6 and 35 records respectively; the largest field is sub-industry label. Fields can overlap, and a term remains a search link rather than verified business activity.

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.

6 candidates match only a name, or lose all product-field matches after the full company name is removed while sub-industry also has no hit. This transparent string test locates copied company descriptions; it does not establish that a company does not operate the business.

16 of this cohort’s 79 records link through existing company-ID mappings to 2026 lists from all jurisdictions (20.3%). 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.

Formulation assessment depends on use and consistency evidence

The Adhesives and sealing materials label covers 24 records (30.4% of this cohort). This archive clue raises a verification question about Use-specific functional formulations with application-test documents; it does not establish that these companies already deliver it.
