8541.60.00.30 - Exceeding 1 MHz, but not exceeding 5 MHZ

This HTS classification covers mounted piezoelectric crystals, specifically quartz crystal units, designed to operate at frequencies exceeding 1 MHz but not exceeding 5 MHz. These components are crucial for maintaining stable and accurate timing functions in a wide range of electronic devices. Examples include quartz oscillators used in microcontrollers, communication equipment, and various industrial control systems where precise frequency generation is essential.

This specific subcategory is distinguished from its siblings by its precise operating frequency range. For instance, it differs from 8541.60.00.10 which covers 32.768 kHz crystals, and 8541.60.00.20 which encompasses crystals operating at frequencies not exceeding 1 MHz (excluding 32.768 kHz). Conversely, it is differentiated from 8541.60.00.50 and 8541.60.00.60, which cover higher frequency ranges exceeding 5 MHz.

As this classification node is a leaf node, there are no further subcategories. Classification within this code is solely determined by the operating frequency of the mounted piezoelectric crystal, with the specified range of 1 MHz to 5 MHz being the definitive criterion. If a crystal falls outside this range, it would be classified under a different sibling code.
