Cover of Second Incorporation Explained

What this guide settles

  • Second incorporation is a BIS practice, not a rule written in the EAR — applied case by case, on the facts
  • It applies only once a first incorporation has produced a distinct, completed foreign product
  • An arm’s-length purchase or separate sale points to a discrete product; your role in its design, manufacture or parts points away
  • It never covers ITAR, applicable zero de minimis, US-origin “600 series” or see-through content, and it must never be engineered

What you get

  • The guide: explanations, method, conditions and limits
  • Worked examples: the discrete-product test, the BIS advisory opinion commented and ten pitfalls
  • Tools printed in the guide: four templates and a readiness check
  • Sources with section references and their verification date
  • Revisions included for 12 months

Printed tools: T1 · Component tiering sheet · T2 · Discrete-product assessment · T3 · Second incorporation record · T4 · Review triggers and change log · Readiness check

What it does not cover

Assumed knowledge. Knowing how a de minimis calculation works, whether your product is foreign-made, and that foreign direct product rules are a separate route.
