N351458 · 2025-08-08 — The tariff classification of a shell and tube heat exchanger from Canada
The merchandise under consideration is referred to as a Slop Rerun Heater and is described as a shell and tube heat exchanger. It is installed in the 331B Module, a building module that will be incorporated into the Nanushuk oil processing facility in Alaska. While the 331B building module will contain multiple subassemblies and other equipment, only the Slop Rerun Heater is under consideration in this request. The shell and tube heat exchanger is used to transfer heat between a glycol medium and a slop oil, which is a mixture of oil and water generated in the processing facility. Entering…
N349493 · 2025-06-12 — The tariff classification of cooling modules from Canada
The merchandise under consideration is referred to as the 431, 433, and 435 Lift Injection Gas ESD Modules that are incorporated into the Nanushuk Processing Facility, a modular plant currently under construction in Alaska. When construction is complete, this facility will process oil deposits from the Nanushuk reservoir into sales quality oil. All three modules are identical in configuration and installed with sequential compressor modules (i.e., module numbers 432, 434, and 436) in the plant. The function of the lift injection gas modules is to cool compressed gas within two gas…
N349078 · 2025-06-03 — The tariff classification of a crude cooler module from Canada
The merchandise under consideration is identified as the 241 Crude Cooler Exchanger Module which will be incorporated into the Nanushuk Processing Facility, a modular plant currently under construction in Alaska. When construction is complete, this facility will process oil deposits from the Nanushuk reservoir into sales quality oil. The function of the 241 Crude Cooler Exchanger Module is to cool crude oil before it enters a downstream module. Its main components include a sales oil mixer, four crude coolers, piping, valves, instrumentation and controls. Other components include exhaust…
N335926 · 2023-10-30 — The tariff classification of a crude heater from Canada
The item under consideration is referred to as a Crude Heater Exchanger Module, which is described as a heat exchanger used in an oil refinery to heat crude oil. It is configured as a carbon steel shell-and-tube heat exchanger where two fluids, of different starting temperatures, flow through the unit. The fluids, namely oil and glycol, will enter through different inlets, remain separated by a barrier, and flow in opposite directions. Before the glycol enters the module, it is heated by a separate system in the facility using recycled waste heat produced from turbine exhaust. As the two…
H316373 · 2021-08-30 — Protest No. 2809-20-105171; Classification of heat exchangers
This is our decision regarding an Application for Further Review (“AFR”) of Protest No. 2809-20-105171 (“lead” protest), filed by Livingston International, Inc. on behalf of Tesla, Inc. (“Tesla” or “Protestant”). The Protest and AFR concern the classification under the Harmonized Tariff Schedule of the United States (“HTSUS”) of heat exchangers. The AFR was forwarded to this office for consideration. No samples were provided for examination. FACTS: The articles at issue in this Protest and AFR are described as Tesla Part Numbers (“TPN”) 1093326-00-C, 1093326-99-C, 1096215-00-C,…
