HS Code for Triac

A Triac (Triode for Alternating Current) is classified under HS code 8541.30. This classification is part of Chapter 85, which covers electrical machinery and equipment. Heading 8541 specifically addresses diodes, transistors, and similar semiconductor devices. The subheading 8541.30 is dedicated to thyristors, diacs, and triacs, excluding photosensitive devices. A Triac is a bidirectional semiconductor switch that can conduct current in either direction when triggered at its gate electrode. Because it is a discrete semiconductor device, it fits perfectly into this category. The classification is based on the physical properties and the electronic function of the component as a power controller. It is important to note that the device must be a discrete component; if the Triac function is integrated into a complex circuit on a single chip with other active and passive elements, the classification might shift to integrated circuits under heading 8542.

Products Included

• Bidirectional triode thyristors
• Standard gate-trigger triacs
• High-power switching triacs
• Logic level triacs for microcontrollers
• Snubberless triacs for inductive loads

Common Misclassification

Triacs are often misclassified under 8541.21 or 8541.29, which are reserved for transistors. While triacs and transistors are both semiconductors, their switching mechanisms and internal structures are distinct. Another common error is 8541.40, which is for photosensitive semiconductor devices; if a triac is triggered by light (an opto-triac), it must be classified there. Finally, complete electronic modules that include a triac along with resistors and capacitors should be classified under 8543 or 8537 depending on their final application.

FAQ

What is the HS code for Triac?

The standard HS code for a discrete Triac semiconductor device is 8541.30.

Are opto-isolated triacs classified here?

No, opto-isolated triacs or photo-triacs are generally classified under HS code 8541.40 because they are photosensitive semiconductor devices.
