About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 9027.50.80.20, specifically classifies instruments and apparatus used for thermal analysis. These devices are designed to measure and study the physical and chemical properties of materials as they are subjected to changes in temperature. Examples include instruments for differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and differential thermal analysis (DTA), which are crucial for material characterization, quality control, and research and development across various industries.

Unlike its sibling category 9027.50.80.15, which covers broader chemical analysis instruments, this subcategory is narrowly focused on the thermal aspects of material analysis. While chemical analysis instruments may incorporate thermal components, this classification is reserved for devices where the primary function and methodology revolve around the measurement of thermal phenomena. The instruments classified here rely on detecting and quantifying heat flow, temperature changes, mass loss, or other thermal events in response to controlled heating or cooling.

As this is a leaf node in the HTS database, there are no further subcategories under 9027.50.80.20. Therefore, the classification hinges on a precise determination that the instrument's core function is thermal analysis using optical radiation. When classifying, consider the intended use and the specific phenomena being measured. If an instrument performs thermal analysis as its principal function, it will fall under this heading, provided it utilizes optical radiation in its operation.
