HS Code for Quartz crystal

Quartz crystals used for electronic purposes are classified under HS code 8541.60. This code is located in Chapter 85, which covers electrical machinery and equipment. Heading 8541 includes diodes, transistors, and similar semiconductor devices, as well as mounted piezo-electric crystals. The classification 8541.60 specifically refers to these mounted crystals. These are not raw minerals but are processed, cut, and mounted components that utilize the piezoelectric effect to create an electrical signal with a very precise frequency. This is essential for the operation of oscillators and resonators in computers, mobile phones, and clocks. The classification is based on the fact that the quartz has been prepared and mounted for use in an electrical circuit, moving it away from the classification of raw minerals or semi-precious stones. The mounting typically involves a protective housing (such as metal or ceramic) and electrical leads or contact pads for surface mounting on a printed circuit board.

Products Included

• Mounted quartz crystal oscillators
• Quartz crystal resonators
• Piezo-electric quartz crystals with electrical leads
• Surface-mount (SMD) quartz crystals

Common Misclassification

Quartz crystals are often misclassified under 2506.10, which is for natural quartz in its crude or raw state. They may also be confused with 7103.10 if they are considered semi-precious stones for jewelry. Another common error is using 3824.99 for synthetic crystals; however, once the crystal is mounted for piezo-electric use, 8541.60 is the specific and correct heading.

FAQ

What is the HS code for Quartz crystal?

The HS code for mounted piezo-electric quartz crystals used in electronics is 8541.60.

Does this code cover raw quartz stones?

No, raw or natural quartz is classified in Chapter 25 (2506.10). HS code 8541.60 only applies to crystals that have been processed and mounted for electrical use.
