Supplier Changes, Substitutions & Reclassification
When something changes after you qualified the item
A step-by-step method for non-US companies that have classified an item and its supplier — to find out what a change of configuration, source, evidence or rules does to that analysis, what it does to the stock and to past operations, and what stays valid.
What this guide settles
- A change is an event to assess, not a reason to reclassify everything — its cause, chronology and population decide what still holds
- The same notice can mean the item changed, the rules changed, or the earlier analysis was wrong: three different consequences for the stock and for the past
- Separate the dates — material change, cut-in, notice, regulatory effective date, internal decision — and define the population: ordered, in transit, in stock, incorporated, delivered
- A new CCATS is read within its scope, a savings clause is a mechanism with conditions, an acquisition is not a name change (§750.7(c), §122.4) — and superseded evidence is kept, not deleted
What you get
- The guide: explanations, method, conditions and limits
- Worked examples: five change triggers, the three explanations of a classification change, the dates and populations to separate, a documented savings clause, §750.7(c) and §122.4 read for a supplier change, the new evidence and what must not be inferred from it, a composite case and ten pitfalls
- Tools printed in the guide: four templates, including an impact matrix and a change assessment and decision record, and a readiness check
- Sources with section references and their verification date
- Revisions included for 12 months
Printed tools: T1 · Change intake sheet · T2 · Impact matrix · T3 · Change assessment and decision record · T4 · Supersession and watch list · Readiness check
