What a source record does—and does not—prove
A verified source record proves which publication the engine used. It does not by itself prove that a product is classified correctly, qualifies for an exclusion or preference, falls within an AD/CVD scope, or satisfies a quota or special-entry condition.
Those conclusions require the facts and deterministic rules described in the calculator’s coverage matrix. Unsupported questions remain review items.
