N348625 May 20, 2025 CLA-2-90:OT:RR:NC:N1:105 CATEGORY: Classification TARIFF NO.: 9031.80.8085; 9903.01.25 Yuichiro Nozaki Sanyo Chemical America 17 Arentzen Blvd., Suite 206 Charleroi, PA 15022 RE: The tariff classification of a sensor module from Japan Dear Mr. Nozaki: In your letter dated May 5, 2025, you requested a tariff classification ruling. Descriptive literature was provided for our review. The item under consideration is described as the 5Q-SSM sensor module, which is a Quartz Crystal Microbalance (QCM)-type smell sensor that detects changes in mass due to the adsorption/desorption of odor molecules onto a membrane surface. These changes are translated into resonance frequency shifts (in Hz) of the quartz crystal unit and output as digital data. The sensor can be embedded into other articles or used as a standalone device. The 5Q-SSM measures 20mm by 28mm by 2.84mm and weighs 10g. It is imported with the sensor (including 5 membranes with different chemical affinity), a USB converter board, an optional protective case, a USB flash drive with software, and a micro-USB cable. The sensor module includes a set of five standardized membranes designed for general odor identification (such as ethanol, toluene, kerosene, etc.). Custom sets tailored for specific applications are also available. The sensor is used for proof-of-concept (POC) evaluation and may be embedded in broader systems or consumer devices for smell detection. The device is intended for Internet of Things (IoT) home monitoring devices (e.g., wall outlets that detect odors), smart agriculture (e.g., detecting gas emissions from crops), odor detection systems in industrial or consumer use, environmental and ambient monitoring, quality control, and healthcare. The applicable subheading for the 5Q-SSM sensor will be 9031.80.8085, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Measuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter; profile projectors; parts and accessories thereof: Other instruments, appliances and machines: Other: Other.” 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 9031.80.8085, 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 jason.m.christie@cbp.dhs.gov. Sincerely, (for) Steven A.
