Descriptive literature was provided for our review. The item under consideration is a robotic shot peening machine designed for the surface treatment and mechanical preparation of metal components. The machine has a mild steel acoustic-lined cabinet, a dual-satellite table work door, an ABB IRB 4600 robot equipped with an automatic tool changer and venturi nozzles/rotary head, an automatic abrasive adder, a urethane reclaim pipe and cyclone separator, a vibratory classifier, a 6.5 CFT double-chamber media tank with Thompson and Magna valves, an Allen-Bradley PLC with touchscreen HMI, and a cartridge-style dust collector. In operation, a metal component is loaded onto a synchronized turntable or work cart, after which the system loads a digital recipe defining the precise tool path, nozzle distance, and impact angle. Within the sealed blast chamber, the articulated robotic arm guides the peening nozzle along contoured surfaces while closed-loop sensors continuously monitor and regulate blast pressure, media flow rate, and peening intensity. Simultaneously, an integrated reclamation system collects, cleans, and recycles spent media by screening out dust and fractured particles to ensure consistent surface treatment, ultimately inducing beneficial compressive stresses that enhance the fatigue life, durability, and stress-cracking resistance of aerospace, automotive, energy, and industrial components. In your submission, you suggest that the shot peening machine is properly classifiable in subheading 8479.81.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for other machines for treating metal. We disagree. Heading 8479 covers machines and mechanical appliances with individual functions that are not more specifically covered by any other HTSUS chapter. In this case, the machine is more specifically described by heading 8424. The applicable subheading for the robotic shot peening machine will be 8424.30.9090, HTSUS, which provides for “Mechanical appliances (whether or not hand operated) for projecting, dispersing or spraying liquids or powders; fire extinguishers, whether or not charged; spray guns and similar appliances; steam or sand blasting machines and similar jet projecting machines; parts thereof: Steam or sand blasting machines and similar jet projecting machines: Other: Other.” The general rate of duty will be free. The 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/. This ruling does not address the applicability of any additional duties, taxes, fees, exactions and/or other charges, which may apply to the goods discussed herein. This includes, but is not limited to, tariffs and other duties as provided for in Subchapter III to Chapter 99, HTSUS. Thus, for example, in addition to the classification stated above, the merchandise covered by this ruling may also need to be reported with either the Chapter 99 provision under which an additional tariff applies or one of the Chapter 99 provisions covering exceptions to such tariffs.
