HS Code for Hollow drill bars

Hollow drill bars and rods, made of alloy or non-alloy steel, are classified under HS code 722880. This classification falls under Chapter 72, which covers iron and steel. Heading 7228 is designated for other bars and rods of alloy steel, as well as hollow drill bars and rods of alloy or non-alloy steel. The defining characteristic of these products is their internal longitudinal cavity, which is essential for the passage of air or water to cool the drill bit and flush out debris during rock drilling or mining operations. According to the Chapter 72 notes, hollow drill bars must have a cross-section that is not purely circular (often hexagonal or octagonal) and an external dimension exceeding 15mm but not 52mm, with the internal cavity not exceeding one-half of the external dimension. If these specific dimensional requirements are not met, the product may be classified as a pipe or tube in Chapter 73.

Products Included

• Alloy steel hollow drill rods
• Non-alloy steel hollow drill bars
• Hexagonal hollow drill steel
• Octagonal hollow drill rods for mining
• Mining drill steel bars

Common Misclassification

Hollow drill bars are most commonly misclassified under 7304, which covers seamless tubes and pipes of iron or steel. The distinction is based on the intended use and the specific cross-sectional geometry defined in the Chapter 72 notes. They may also be confused with 843143, which covers parts for boring or sinking machinery; however, the raw bar or rod is classified by its material composition in Chapter 72 rather than as a machine part.
