9025.11 - Liquid-filled, for direct reading:

This HTS category, 9025.11, specifically covers liquid-filled thermometers and pyrometers designed for direct reading. These instruments utilize the expansion or contraction of a liquid (such as mercury or alcohol) within a sealed tube to indicate temperature. They are characterized by their straightforward design, where the temperature is directly visible on a calibrated scale without the need for electronic display or recording mechanisms. Examples include standard laboratory thermometers, cooking thermometers, and many industrial temperature gauges that rely on liquid expansion.

In contrast to its sibling category, 9025.19, which encompasses "Other" thermometers and pyrometers (including those not liquid-filled or not for direct reading, such as bimetallic or electronic thermometers), 9025.11 is exclusively for liquid-filled, directly readable types. The key differentiator lies in the presence of a liquid column and the direct visual interpretation of the temperature reading from the scale.

Within this category, further subdivisions exist to refine classification. The subcategory 9025.11.20.00 covers clinical thermometers, which are typically designed for measuring human body temperature and often have specific features for ease of use and accuracy in a medical context. The subcategory 9025.11.40.00, "Other," captures all other liquid-filled, directly readable thermometers and pyrometers that do not fall under the specific classification of clinical thermometers. This ensures precise categorization based on the instrument's intended application.
