9018.90.68.00 - Printed circuit assemblies for the defibrillators of subheading 9018.90.64

This HTS classification, 9018.90.68.00, specifically covers printed circuit assemblies that are integral components of defibrillators classified under subheading 9018.90.64. These printed circuit assemblies are the sophisticated electronic brains of the defibrillator, containing the logic, power control, and user interface circuitry necessary for the device's operation. Their primary function is to process signals, manage energy delivery, and facilitate the diagnostic and therapeutic capabilities of the defibrillator.

Distinguishing this category from its sibling, 9018.90.64 (Defibrillators), is crucial. While 9018.90.64 encompasses the complete, finished defibrillator device, 9018.90.68.00 is reserved for the unassembled or sub-assembled printed circuit boards themselves, before they are integrated into the final medical apparatus. It is important to note that this classification is for the component part, not the finished product.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification under 9018.90.68.00 relies on the specific designation of the printed circuit assembly as being intended for use in defibrillators of subheading 9018.90.64. This determination is typically based on documentation, markings, or the inherent design and function of the circuit assembly itself, indicating its direct relationship to the operation of a defibrillator.
