U.S. imports of Thermostats (SITC 87461) totaled $89.6M in August 2026, imported from 56 countries.
Importers of Thermostats paid $5.9M in duties in August 2026, an average duty rate of 6.58% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataThermostats — devices that automatically regulate temperature by switching heating or cooling systems in response to a sensed temperature signal — serve as a primary control element across HVAC, refrigeration, industrial process, and appliance applications. Classification as a thermostat rather than as a general temperature controller or sensor depends on the device's self-acting or automatic switching function; programmable and smart thermostats with network connectivity are widely traded and may raise additional questions about whether the communication module changes the classification. Many thermostats imported from certain origins are subject to Section 301 tariff considerations, making origin and HTS subheading verification routine for importers.

A thermostat with integrated wireless communication is generally still classified as a thermostat if its primary function remains automatic temperature regulation. The communication module is considered ancillary to the principal function. However, if the device is primarily a network hub or controller that incidentally includes a temperature sensor, a different classification may apply — the essential character of the article governs.
Both bimetallic (mechanical) and electronic thermostats fall within this heading; the operating principle does not change the heading-level classification. Distinctions between mechanical and electronic types are relevant at the subheading level, where the schedule may separate them, so importers should confirm the correct subheading based on the device's sensing and switching mechanism.
