Last updated: August 2026 dataHollow drill bars and rods are purpose-engineered steel products with an axial bore that allows flushing fluid or air to pass through during rock drilling and mining operations, distinguishing them functionally and commercially from solid bars. Unlike most other headings in Chapter 72, this heading covers both alloy and nonalloy steel in a single line (7228800000), so the alloy content does not drive classification here — the hollow, drill-specific geometry does. China is the dominant supplier to the US market, with the United Kingdom and Italy also notable sources of higher-specification grades used in underground mining and geotechnical drilling.

Hollow drill bars are classified in Chapter 72 (iron and steel) rather than Chapter 73 (tubes and pipes) because they are solid-bar products with a central bore, not tubular products manufactured as hollow sections. The key classification factors are the product's cross-sectional geometry, wall thickness relative to bore diameter, and its design for use as a drill rod rather than for fluid conveyance. CBP rulings have addressed this distinction, and importers should review applicable rulings if the product's geometry is borderline.
Yes. Hollow drill bars from China are subject to Section 232 steel tariffs, and Chinese-origin steel products may also be subject to Section 301 tariffs depending on the specific tariff line and any applicable exclusions. Importers should evaluate both measures simultaneously when calculating landed cost, as the combined exposure can be substantial.
