HTS heading 7019 is a broad product category for glass fibers, including glass wool, and products made from those fibers. It can include forms such as yarn, rovings, woven fabrics, mats, and other articles, depending on the product’s construction and intended classification. The heading is about the material and the form of the goods—not simply any product that contains some glass.
To reach the correct 8-digit HTSUS code, start with the product’s physical form and how it is made. Subheadings commonly distinguish among types of glass-fiber material and articles, such as yarn, rovings, fabrics, mats, or other finished goods, and may further separate products by characteristics such as coating, construction, or use. Review the full tariff wording, legal notes, and statistical descriptions; do not choose a code based only on a catalog name or marketing term.
What to check
- Identify whether the item is glass fiber itself or an article made from it, then record its form—such as yarn, roving, fabric, mat, or insulation.
- Confirm the fiber’s construction and key specifications, including filament or staple form, weave or nonwoven structure, coating or treatment, and dimensions where relevant.
- Use the HTSUS subheading text and statistical suffix descriptions to compare all plausible 8-digit options; read any applicable section or chapter notes.
- Obtain product specifications, technical sheets, composition details, and representative samples when the tariff wording depends on physical characteristics.
- Ask a customs broker or seek a binding classification ruling when the product could fit more than one subheading or its construction is unusual.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
