Import Preference Scheme

Preferential-origin duty schemes — an origin (and optional destination), effective-dated, with rates under it.

Not wired into any calculation yet. This is the scheme/rate tables and a read-only lookup only — no receipt, container landed cost, or GL posting reads it. Applying a resolved preferential rate to a real import’s landed cost is separate, higher-stakes work.

Preference schemes

A scheme names an origin, and can also be scoped to one destination — leave destination unset for a scheme that applies to any of this company’s destinations. Unlike a duty schedule, a scheme can lapse: set effective to the day an agreement is superseded.

Preferential rates

A rate under a scheme, effective from a date, never edited in place. Leave HS commodity unset for the scheme’s blanket rate; a rate naming a commodity beats that fallback.

Test a lookup

What preferential rate would apply, and why — the exact rule an import clearing on this date resolves to, before anything is actually cleared.
