Product Description

The three thermostats in this request are Signature, Home, and Element. The Signature thermostat is a WiFi enabled floor heating thermostat. Its functions include, a 7-day programmable thermostat, which can be controlled by a mobile smart phone or web browser or a 3.5", 320x480 pixel color touchscreen. The Home thermostat is a 7-day programmable floor heating thermostat. It can be controlled by a 3.5", 320x480 pixel color touchscreen. The Element thermostat is a non-programmable floor heating thermostat. It has a simple on/off, up/down buttons to control the temperature.

The three thermostats control any compatible electric floor heating system using a 10K Ω sensor (thermistor). The thermostats are connected to a floor heating mat or an in-floor cable to create a heating system. They feature dual voltage compatibility and provide the power to the floor heating mat or cable.

Analysis and Justification

Legal Note 7(a) to Chapter 90 reads heading 90.32 applies only to "Instruments and apparatus for…automatically controlling temperature, whether or not their operation depends on an electrical phenomenon which varies according to the factor to be automatically controlled, which are designed to bring this factor to, and maintain it at, a desired value, stabilized against disturbances, by constantly or periodically measuring its actual value".

Thermostats are specifically named in the Customs Tariff at the sub-heading level 9032.10. At the tariff heading level, thermostats need to meet the condition for use with machinery or equipment.

You have provided information indicating that after importation these goods are to be used with the specific heating system "Nuheat". The thermostats are connected to floor heating mats or in-floor cables to create a floor heating system. The thermostats measure the temperature in the room or floor. To maintain the temperature in a room, the thermostats automatically activate the heating mats and in-floor cables by sending power to them. The heating mats and cables heat up the surrounding floor and air, maintaining the desired temperature of the room.


Section 10 of the Customs Tariff directs that classification of imported goods shall be determined in accordance with the General Rules for the Interpretation of the Harmonized System. Section 11 of the Customs Tariff states that in interpreting the headings and subheadings, regard shall be had to the World Customs Organization's (WCO) Explanatory Notes to the Harmonized Commodity Description and Coding System.

General Interpretative Rule 1 (GIR 1) directs that titles of Sections, Chapters and sub-Chapters are provided for ease of reference only. For legal purposes, classification shall be determined according to the terms of the heading and any relative Section and Chapter Notes. Similarly, General Interpretative Rule 6 (GIR 6) directs that classification shall be determined according to the terms of those subheadings and any related Subheading Notes.

In accordance with GIR 1 and 6, the Signature, Home, and Element thermostats are classified under 9032.10.10.00 as thermostats for use with machinery or equipment.
