When is an origin dossier audit ready?

When source data, decision logic, review history, and exportable rationale stay visible per claim.

Why should ROSA and BOI live in the same workflow?

Because teams need to explain legal basis and operating application together.

What role does LTSD play here?

LTSD supports the evidence layer for origin claims and makes supplier proof reusable.

Preferential origin as a governed decision system

Connect regulation, supplier evidence, ROSA/BOI logic, and dossier building inside one repeatable operating model.

Direct answer

What is preferential origin?

Preferential origin determines whether goods qualify for a reduced or zero import duty under a trade agreement. The assessment follows the product-specific origin rule and requires evidence about materials, processing, and supplier declarations. A claim is defensible only when the rule, calculation, evidence, and review are recorded together in the dossier.

Check the product-specific rule.
Record materials and processing traceably.
Have the evidence and decision independently reviewed.

Why origin decisions become slow and fragile

Supplier declarations, ROSA checks, and dossier notes live in separate places.
Manual calculations make review and reuse difficult.
Teams identify weak claims too late in the process.

Operating model for origin governance

Connect BOM data, supplier evidence, and decision rules in one traceable intake.
Treat review, exceptions, and release as explicit workflow lanes.
Maintain exportable evidence dossiers per claim and supplier.
