Every strong cluster needs a source hierarchy.
TEDA Union separates official trade statistics, tariff classification, regulatory guidance, government portals and platform documentation from commercial interpretation.
12 official or first-party source systems.
These sources can establish trade context, classification, regulation, company-registration context or platform rules. TEDA Union does not convert them into buyer-intent or supplier-quality claims without separate evidence.

Open source ↗2 published datasets have passed the numeric validation gate.
A cluster may exist before a numeric dataset does. TEDA only calls a numeric page “verified” after the Trade Intelligence gate confirms the official series, product description, annual values, current monthly series and origin-country comparison.
30 clusters connected to the source registry.
The registry lets TEDA expand content without inventing market numbers. Product-level HTS, compliance and commercial evidence are added as each cluster deepens.
