The CHIPS Act provides incentives for domestic semiconductor fabrication and imposes 'guardrails' restricting recipients from expanding certain production in countries of concern. For importers, this means downstream customers may increasingly require documentation of component origin and fab location to confirm supply-chain compliance with their own CHIPS-related obligations.

NAICS 3344 covers the manufacture and trade of discrete components and integrated circuits — the building blocks of electronic systems — while NAICS 3345 covers finished instruments that incorporate those components to perform measurement, navigation, or control functions. The distinction matters when mapping NAICS codes to HTS chapters for trade flow analysis or regulatory reporting.
