N364449 · 2026-09-02 — RE: The tariff classification of an industrial water cooling tower from South Korea
The merchandise under consideration is an industrial steel water cooling tower, model number OTTX-350L, with an induced-draft, cross-flow, and open-circuit design. It features a cold-water basin, a hot-water basin, and dual vertical fill banks mounted in a structural frame enclosed by panels. During its operation, hot process water is piped to the top of the unit, where it is distributed by gravity over PVC packing in the fill banks, which are located on opposite sides of the unit. At the top of the unit is an induced-draft fan assembly equipped with an axial air-foil fan. The fan draws…

N361753 · 2026-06-16 — The tariff classification of prefabricated modules from Thailand
The subject prefabricated modules will be permanently installed at a petrochemical manufacturing facility in Texas. The modules are designed to be stacked vertically on piling foundations to form an ethane cracking furnace, which is described as a thermal processing unit that uses high-temperature cracking to convert ethane feedstock into ethylene and hydrocarbon products. Within the furnace, ethane is mixed with steam at elevated temperatures, a process that breaks molecular bonds and creates lighter hydrocarbon products. A total of ten modules will be imported together in a single shipment.…
