Sub-classifications

Commodity Code
Description

Overview

This HTS category encompasses a broad range of products derived from glass fibers, including glass wool. It covers articles such as yarn, rovings, woven fabrics, and other manufactured items where glass fibers are the primary constituent material. The intent is to classify finished or semi-finished goods made from these fibrous glass materials, differentiating them from raw glass materials or finished articles not primarily composed of glass fibers.

Within the broader context of Section XIII, which deals with a variety of non-metallic mineral products, Chapter 70 specifically addresses glass and glassware. While other chapters might cover woven fabrics or yarns made from different materials, this category is exclusively for those composed of glass fibers, distinguishing them from textile materials like cotton, wool, or synthetic fibers. It is important to note that this category is distinct from pure glass products like sheets or containers, as it focuses on the fibrous form and its derivatives.

The subcategories within 7019 provide further specificity based on the processing and form of the glass fibers. These subdivisions delineate between various forms like slivers, rovings, yarn, chopped strands, and mats, as well as different methods of bonding fabrics (mechanically or chemically). A specific designation is provided for glass wool and its articles, reflecting its common usage and distinct characteristics. Finally, the "Other" category captures any remaining glass fiber articles not otherwise specified.
