HTS heading 8464 is a broad product category for machine tools that work stone, ceramics, concrete, asbestos-cement, similar mineral materials, or glass when the glass is worked cold. It can include equipment used for operations such as sawing, grinding, polishing, drilling, cutting, or shaping, depending on the machine’s design and function. The heading covers the machine tool itself, not every product made from these materials.
To reach the correct 8-digit HTSUS code, first confirm that the machine belongs in heading 8464, then identify its principal working operation and the material or materials it is designed to process. The lower-level subheadings generally distinguish among machine types and material or function groupings. Review the complete tariff description, legal notes, unit of quantity, and any relevant statistical suffix—not just a product title—and obtain broker or customs advice when the machine has multiple functions or could fit another heading.
What to check
- Describe the machine’s actual operation, such as sawing, grinding, polishing, drilling, or shaping, and confirm that it is a machine tool rather than a general-purpose appliance.
- Identify the material the machine is designed to work: stone, ceramics, concrete, asbestos-cement, another like mineral material, or glass worked cold.
- Check whether the machine performs more than one operation and determine its principal function using the product specifications, manuals, and technical documents.
- Compare heading 8464 with potentially competing headings for specialized machinery, and apply the HTSUS General Rules of Interpretation and relevant legal notes.
- Verify the full 8-digit HTSUS description, country-of-origin treatment, unit of quantity, and current official tariff information before entry; ask a customs broker or request a formal classification ruling if uncertainty remains.

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.
