The merchandise under consideration is described as Quasi-Continuous Wave (QCW) laser diode stacks, Part numbers: PDBX0333, PDBX0507, PDBX0410, PDBX0017. They consist of multiple unmounted laser diodes soldered together on a copper heat sink to form a stack. The subject laser diode stacks are available in different variations with vertical or horizontal light emission and can be mounted using threaded holes, through holes or studs. We note that the laser diode stacks are designed as components for industrial and medical laser systems. The applicable subheading for the QCW laser diode stacks will be 8541.41.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “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): Light-emitting diodes (LED).” The general rate of duty will be Free. Effective April 5, 2025, Executive Orders implemented “Reciprocal Tariffs.” All imported merchandise must be reported with either the Chapter 99 provision under which the reciprocal tariff applies or one of the Chapter 99 provisions covering exceptions to the reciprocal tariffs. At this time, products of the European Union with an ad valorem (or ad valorem equivalent) rate of duty under column 1-General less than 15 percent will be subject to an additional ad valorem rate of duty of 15 percent minus the column 1-General duty rate. At the time of entry, you must report the Chapter 99 heading applicable to your product classification, i.e. 9903.02.20, in addition to subheading 8541.41.0000, HTSUS, listed above.
