RE: The tariff classification of integrated circuit sockets from Japan
Dear Ms. Furuoka:
In your letter dated May 21, 2025, you requested a tariff classification ruling. Descriptive literature was
provided for our review.
The items under consideration are described as integrated circuit (IC) sockets, which are devices used for
testing semiconductor chips during the semiconductor manufacturing processes. These sockets are mounted
onto a burn-in board (BIB), or test board, during quality control and reliability assessments. The BIB is
connected to a pattern generator and power supply in the burn-in chamber. The chamber that surrounds the
burn-in board provides an environment for testing the chips under a range of temperatures (from -60°C to
150°C). The sockets ensure secure electrical contact with the device under test and allow repeated insertions
without causing damage to the chip. The IC sockets are used solely in the semiconductor testing environment
and are primarily used for testing applications in consumer electronics, automotive, and industrial integrated
circuits.
The applicable subheading for the IC sockets will be 9030.82.0000, Harmonized Tariff Schedule of the
United States (HTSUS), which provides for “Oscilloscopes, spectrum analyzers and other instruments and
apparatus for measuring or checking electrical quantities, excluding meters of heading 9028; instruments and
apparatus for measuring or detecting alpha, beta, gamma, X-ray, cosmic or other ionizing radiations; parts
and accessories thereof: Other instruments and apparatus: For measuring or checking semiconductor wafers
or devices (including integrated circuits).” 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 from all countries
will be subject to an additional 10 percent ad valorem rate of duty. At the time of entry, you must report the
Chapter 99 heading applicable to your product classification, i.e. 9903.01.25, in addition to subheading
9030.82.0000, 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 Jason Christie at [email protected].
Sincerely,
(for)
Steven A. Mack
