What is the 6-digit WCO tariff classification and Thailand (Thai Customs) general duty for Diodes, other than photosensitive or light-emitting diodes (LED)?
Under WCO Harmonized System 2022 and Thailand (Thai Customs), Diodes, other than photosensitive or light-emitting diodes (LED) is classified under HS 8541.10 (Heading 8541, Chapter 85). The representative TH MFN general duty rate is 0%.
How is HS 8541.10 distinguished within Heading 8541 (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; parts thereof)?
Heading 8541 covers 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; parts thereof. Subheading 8541.10 specifically isolates Diodes, other than photosensitive or light-emitting diodes (LED). Importers must verify whether physical characteristics, processing state, or composition require alternative subheadings under Heading 8541.
What are the primary candidate subheadings related to HS 8541.10?
Related subheadings under Heading 8541 include 8541.21, 8541.29, 8541.30, 8541.41, 8541.42, 8541.43, 8541.49, 8541.51. Classification depends on processing stage, decaffeination, purity, or material form.
What mandatory commercial entry documents are required to import Diodes, other than photosensitive or light-emitting diodes (LED)?
Commercial Invoice (detailing Incoterms, currency, and origin), Packing List, Bill of Lading (or Air Waybill), CBP Form 7501 Entry Summary, and a continuous customs bond are required for formal entries.
Can goods under HS 8541.10 enter duty-free under USMCA or Free Trade Agreements?
Yes. Eligible goods originating in Mexico, Canada, South Korea, or Australia enter duty-free under preference SPI codes (P, KR, AU) provided they satisfy Regional Value Content (RVC) or tariff-shift rules with a valid Certificate of Origin.
What is the US formal entry threshold for shipments of Diodes, other than photosensitive or light-emitting diodes (LED)?
Commercial shipments of Diodes, other than photosensitive or light-emitting diodes (LED) with a customs value exceeding $2,500 USD require formal customs entry (CBP Form 7501) and a continuous entry bond. Informal entry applies to lower values.
How can an importer obtain a binding CBP classification ruling for HS 8541.10?
