# HS code 8541.29: Transistors, other than photosensitive transistors > HS code 8541.29 covers transistors, other than photosensitive transistors, other than those classified in 8541.21. It sits in heading 85.41 (semiconductor devices (for example, diodes, transistors, semiconductor-based transducers); photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; light- emitting diodes (LED), whether or not assembled with other light-emitting diodes (LED); mounted piezo-electric crystals) in chapter 85 (electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles). Other goods of heading 85.41 are classified under 8541.10 (diodes, other than photosensitive or light-emitting diodes (LED)), 8541.21 (transistors, other than photosensitive transistors, with a dissipation rate of less than 1 W), 8541.30 (thyristors, diacs and triacs, other than photosensitive devices), 8541.41 (photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; light-emitting diodes (LED), light-emitting diodes (LED)) or 7 others. National tariff lines under 8541.29 are live on border.bot for the United States (4 lines, also used by 1 other country).

Its first two digits, 85, are the chapter; the first four, 8541, are heading 85.41; the last two, 29, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 85: Electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles - Heading 85.41: Semiconductor devices (for example, diodes, transistors, semiconductor-based transducers); photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; light- emitting diodes (LED), whether or not assembled with other light-emitting diodes (LED); mounted piezo-electric crystals - Within the heading: Transistors, other than photosensitive transistors - Subheading 8541.29: Other ## In other countries National tariff lines under 8541.29 are live on border.bot for the United States (4 lines, also used by 1 other country). - [United States](https://border.bot/countries/united-states/hs-codes/854129): 4 lines, used by 1 other country - Previous subheading: [8541.21](https://border.bot/hs-codes/854121) Transistors, other than photosensitive transistors: With a dissipation rate of less than 1 W - Next subheading: [8541.30](https://border.bot/hs-codes/854130) Thyristors, diacs and triacs, other than photosensitive devices ## Frequently asked questions ### What does HS code 8541.29 cover?
