N183162 · 2011-09-25 — The tariff classification of a Hot Runner Controller from Canada
No samples were provided. The Hot Runner Controller, a component of a plastic injection molding system, has the ability to receive temperature measurements from up to 384 zones primarily to turn on and off heaters to ensure that the plastic resin that is being injected is brought to and is maintained at the predetermined, desired temperature, which is presumed to result in its having therefore the appropriate viscosity. Secondary functions are to turn on and off heaters to bring and maintain (a) the resin at a non-destructive temperature when the injection process is interrupted and (b) the…
a84546 · 1996-07-10 — The tariff classification of a locomotive engine temperature controller from Canada
, you requested a tariff classification ruling. The item at issue is the model Q-85148 Fan Control, a solid-state, micro-processor based electronic temperature controller used to regulate locomotive engine cooling fans. The unit utilizes two temperature sensors to monitor the engine temperature and then issues control commands to upwards of 10 cooling fans and/or air control shutters. The applicable subheading for the fan control will be 9032.89.6040, Harmonized Tariff Schedule of the United States (HTS), which provides for automatic regulating or controlling instruments and apparatus;…
a82553 · 1996-05-28 — The tariff classification of turbomolecular vacuum pumps; and temperature control systems for such pumps from Japan
The items at hand are a series of magnetically levitated turbomolecular vacuum pumps. The pumps are used in the semiconductor industry for chemical vapor deposition. In addition the pumps may be shipped either with their temperature management system, (TMS) or the TMS may be shipped separately. The temperature control system consists of an electronic control module, remote temperature probe, heater core, solenoid control valve, and copper cooling water tubes. The purpose of the TMS is to maintain pump temperature at 55 degrees Celsius. The controller manages the pump temperature by regulating…
891867 · 1993-11-26 — The tariff classification of digital temperature meters and digital temperature controllers from Taiwan
The items involved in this portion of your inquiry consist of the models DM-496 and DM-492 temperature controllers, and the models DM-4T and TCM-4T temperature meters. All of the units have digital displays, are calibrated in degrees centigrade, and accept measurement inputs from a wide range of thermocouples or RTD'S. The primary difference between the two groups is that the temperature controllers have adjustable setpoints and proportional relay controls for initiating or stopping remote operations. The applicable subheading for the models DM-496 and DM-492 temperature controllers will be…
889863 · 1993-09-28 — The tariff classification of electronic temperaturecontrollers from England.
The items involved in this request are the HRC Mains Voltage, the HRC Low Voltage, and the HRS Low Cost temperature control computer system. The systems are designed to handle up to several temperature zones. They utilizes electronic thermal sensors to monitor existing temperature levels, compare this data to preset levels in the controller, and regulate the voltage levels to thermo-electric heaters to maintain the required temperature. The applicable subheading for the PMS line of temperature controllers will be 9032.89.6040, Harmonized Tariff Schedule of the United States (HTS), which…
