Chapter 68 of the Harmonized Tariff Schedule (HTS) generally covers manufactured or worked articles made from stone, plaster, cement, concrete, mineral materials, abrasives, mica, asbestos-related materials, and similar substances. Examples include worked building stone, grinding wheels, abrasive products, mineral insulation, asphalt articles, plaster products, cement articles, friction materials, and other mineral articles not classified more specifically elsewhere.
The HTS is organized from broad to specific: a chapter identifies a product family, a heading uses four digits to describe a major product group, a subheading adds detail at six digits, and the complete U.S. classification normally appears as a 10-digit HTS number. For example, a product may begin in Chapter 68, move to a heading such as 6809 or 6810, then be narrowed by its material, construction, use, or other characteristics. The correct code depends on the product as imported, not merely on its marketing description.
What to check
- Identify the product’s exact material, composition, and manufacturing process; do not classify it by intended use alone.
- Compare the product with the heading text, section and chapter notes, and applicable subheading descriptions, including exclusions that direct goods to another chapter or heading.
- Check whether the item is a finished article, an input material, an abrasive mounted on a base, or a part of another product, because these distinctions can change classification.
- Review the General Rules of Interpretation and relevant U.S. Customs and Border Protection rulings; obtain customs-broker or classification-professional advice when the wording or composition is uncertain.
- After finding the 10-digit HTS code, check current tariff data for any Chapter 99 provisions, additional duties, exclusions, quota measures, or other trade remedies that may apply separately.
How to use this chapter
A chapter is the first classification level, not a duty rate. Choose the heading that describes the product, narrow by material, construction, use, or other legal distinctions, and verify the final line against the official HTS notes.
