Evaluating Tariff Headings for Multi Component Integrated Circuits under Note Nine
Classification under heading 8542 demands mold-encapsulated leadframe or silicon substrates without printed wiring, securing zero percent ITA tariff treatment.
Harmonized System Note 9
Meaning
Legal definitions within the international trade code specify the requirements for classifying multi-component integrated circuits. The adoption of harmonized system note 9 allows modern electronic modules containing sensors and processors to be grouped under a single heading rather than as separate parts. This note identifies the specific combination of elements that must be present for a module to qualify as a multi-component integrated circuit.
It applies to devices where the components are bonded together on a single substrate to form a functional unit.
Component Definition
Technical criteria for the integration of active and passive elements are listed within this provision. Under harmonized system note 9, a module may include micro-electromechanical systems alongside standard silicon chips. The note ensures that technological progress in miniaturization is seen in the way goods are taxed at the border.
Assembly Boundary
Component boundaries are strictly defined to prevent the misclassification of large assemblies as single circuits. If a module contains discrete components that are not permanently bonded as required by harmonized system note 9, it must be classified according to the individual parts or its overall function. This distinction prevents manufacturers from claiming a lower duty rate for products that are actually finished devices.
Tariff Application
Correct use of harmonized system note 9 facilitates the movement of advanced electronics through international supply chains.
