Query China import or export observations by recorded major-commodity label. Inputs: period, commodity, flow and optional metric. Selected exact Chinese aliases and normalized existing names are supported; this is not general translation or HS-code classification. Returns trade_value or quantity observations with original commodity labels, units, scope, source_class, provenance, snapshot, pagination and limits. No category merging or conversion. No match returns an empty data array. Required: period, commodity, flow. Missing required or invalid input produces an argument error.
