Structured charcoal database
Charcoal product and specification data, separated from marketing claims.
Charcoal Hub Data is the structured data layer of Charcoal Hub: product records, size classes, packaging formats and the public-standard methodology that makes those numbers comparable between suppliers.
The record collections on this site (products, applications, sizes, packaging) are defined but empty. No product, manufacturer or test-report entry has passed verification yet, so no values are published. This page describes what the database covers and how records are structured.
01 · Schema
What this database covers
Every section below is a defined collection with a strict data schema. Record collections stay empty until a supplier record is verified; methodology pages are published now because they describe public standards rather than supplier claims.
Product records
One record per supplier product: identity, raw material, form and dimensions, the proximate measurements (ash, moisture, fixed carbon, volatile matter), burning time, packaging, MOQ and verification status.
Product types
The classification axes used to group products — raw-material base, carbonised form and product family — so records can be filtered without inventing names.
Applications
How records are tied to end use (water-pipe/hookah, commercial grilling, and other combustion uses) with the raw materials and specifications each application depends on.
Size classes
Nominal dimensional classes (cube edge or diameter in millimetres) with their tolerance expectations and the products typically sold in each class.
Packaging formats
Carton and bag configurations with the typical minimum order quantity and private-label options associated with each format.
Specifications (methodology)
Eight public-standard methodology pages explaining what each measured metric means, how it is determined, and what a buyer should ask for. These are knowledge pages, not test results.
02 · Provenance
How a record earns its place
Each product record carries a data_source, a verification_status and a last_verified date. Nothing is published on a supplier's word alone.
| Status | Meaning |
|---|---|
| Unverified | Claim captured from a supplier but not yet checked — not published as a record. |
| Supplier-declared | Values supplied by the producer; no supporting document reviewed yet. |
| Document-verified | Checked against a supplier document (spec sheet, packing list, certificate of analysis). |
| Third-party tested | Confirmed by a laboratory report on a real batch sample. |
The methodology pages explain why: ash, moisture, volatile matter, fixed carbon, burning time and size tolerance all depend on the method and the conditions used. Start with ash content and size tolerance.
03 · Network
Part of the Charcoal Hub network
This sub-site holds the structured data. Sourcing, manufacturer verification and laboratory methodology live on the sibling sites.
Product catalogue
The main buying site, including ready-to-quote product pages such as coconut shell charcoal.
Testing & methodology
Laboratory-side detail on how each measurement is performed and reported.
Manufacturer directory
Producer profiles and verification records behind the product data.
