HTS heading 2524 is a broad four-digit category for asbestos. It generally groups asbestos in forms such as crude or processed mineral material, fibers, and other forms identified by the tariff schedule. The heading is about the asbestos material itself; an article made with asbestos may instead belong in a heading based on the article’s function or construction.
To choose an eight-digit HTSUS code, start with the product’s exact form and composition, then read the subheadings and statistical suffixes under heading 2524. The more specific code may depend on the type or condition of the asbestos, such as whether it is crude, fiber, or another specified form. Confirm the result against the current HTSUS text, relevant section or chapter notes, and any applicable Customs guidance.
What to check
- Obtain a detailed product description, including asbestos type, physical form, processing, packaging, and intended use.
- Check whether the shipment is asbestos material covered by heading 2524 or a finished article that may be classified elsewhere.
- Read every subheading and eight-digit statistical breakout under heading 2524 rather than stopping at the four-digit heading.
- Compare the product’s technical documents, safety data sheet, and supplier specifications with the tariff wording.
- Seek a customs broker or binding classification ruling when the material, processing, or finished-product classification is unclear.
HTS heading 2524 summary
Asbestos is a 4-digit product category containing 2 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
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.

Common questions

Asbestos. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
