7308.30.10.00 - Of stainless steel

This HTS subcategory, 7308.30.10.00, specifically covers doors and windows, as well as their frames and thresholds, when they are manufactured from stainless steel. These items are prepared for use in the construction of structures falling under the broader heading of Chapter 73, which deals with articles of iron or steel. The defining characteristic for classification under this code is the primary material composition, which must be stainless steel.

This classification is distinguished from its sibling category, 7308.30.50, by the material of construction. While both cover doors, windows, frames, and thresholds for structures, 7308.30.10.00 is exclusively for those made of stainless steel, whereas 7308.30.50 encompasses all other types of doors, windows, and related components within this heading that are not of stainless steel. Therefore, the presence of stainless steel is the sole determinant for choosing this particular classification over its sibling.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 7308.30.10.00 signifies a final determination for these specific stainless steel structural components. Examples of goods that would fall under this code include stainless steel casement windows, stainless steel framed patio doors, stainless steel thresholds for industrial buildings, and stainless steel decorative grilles intended for window openings, provided they are designed for structural integration.
