Product classification
HS code for Hollow drill bars: 7228.80
Steel, alloy or non-alloy, hollow drill bars and rods.
Classification of hollow drill bars under HS 7228.80
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.

Codes often confused with 7228.80
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
