Overview

This HTS category, 6902.90.50.10, specifically covers "Clay" when it is intended for use as refractory constructional goods, falling under the broader classification of refractory ceramic products. These materials are designed to withstand high temperatures and are essential components in the construction and lining of furnaces, kilns, incinerators, and other high-heat industrial applications. The "Clay" designation at this specific code signifies that the primary refractory material is derived from various types of clay, processed and fired to achieve the necessary heat-resistant properties.

This category distinguishes itself from other "Other" entries within the 6902.90.50 umbrella by its explicit designation of "Clay" as the principal constituent. While sibling categories under 6902.90.50.20 might also be classified as "Other" refractory ceramic goods, the distinguishing factor for 6902.90.50.10 lies in the specific raw material composition, highlighting clay-based refractories. This differentiation is crucial for accurate tariff application, as it recognizes the inherent properties and common applications of clay as a refractory material.

As a leaf node, this classification has no further subcategories. Therefore, the focus for classification under 6902.90.50.10 is on confirming that the refractory constructional good is indeed primarily composed of clay and meets the general requirements for refractory ceramic products outlined in Chapter 69. Classification relies on the physical characteristics, intended high-temperature application, and the documented material composition of the imported or exported article.
