RE: The tariff classification of QCW laser diode stacks from France
Dear Mr. Maines:
In your letter dated August 14, 2025, you requested a tariff classification ruling.
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.
The tariffs and additional duties cited above are current as of this ruling’s issuance. Duty rates are provided
for your convenience and are subject to change. The text of the most recent HTSUS and the accompanying
duty rates are provided at https://hts.usitc.gov/.
The holding set forth above applies only to the specific factual situation and merchandise description as
identified in the ruling request. This position is clearly set forth in Title 19, Code of Federal Regulations
(CFR), Section 177.9(b)(1). This section states that a ruling letter is issued on the assumption that all of the
information furnished in the ruling letter, whether directly, by reference, or by implication, is accurate and
complete in every material respect. In the event that the facts are modified in any way, or if the goods do not
conform to these facts at time of importation, you should bring this to the attention of U.S. Customs and
Border Protection (CBP) and submit a request for a new ruling in accordance with 19 CFR 177.2.
Additionally, we note that the material facts described in the foregoing ruling may be subject to periodic
verification by CBP.
This ruling is being issued under the provisions of Part 177 of the Customs and Border Protection
Regulations (19 C.F.R. 177).
A copy of the ruling or the control number indicated above should be provided with the entry documents
filed at the time this merchandise is imported. If you have any questions regarding the ruling, please contact
National Import Specialist Steven Pollichino at [email protected].
Sincerely,
(for)
