HS Code for Hollow drill rods

Hollow drill rods are classified under HS code 7228.80 because they represent a specific category of steel products designed for the manufacture of drill bits or for use as drill rods in mining and construction. According to the General Rules of Interpretation (GRI) and the Chapter 72 notes, these items are defined by their cross-section, which must be suitable for drilling. The classification covers both alloy and non-alloy steel variants, provided they meet the structural requirements of being hollow and having an external cross-section that is typically circular, hexagonal, or octagonal. The internal hole must be longitudinal and run the entire length of the rod, serving as a conduit for cooling fluids or air during the drilling process. Because these are semi-finished products or specific structural shapes rather than finished mechanical tools, they remain within the iron and steel chapter rather than the tools chapter.

Products Included

• Alloy steel hollow drill bars
• Non-alloy steel hollow drill rods
• Hexagonal hollow drill steel
• Circular cross-section hollow bars for rock drilling
• Octagonal hollow drill rods

Common Misclassification

Hollow drill rods are frequently confused with seamless tubes and pipes classified under HS code 7304. The primary distinction lies in the intended use and the metallurgical properties; 7228.80 is reserved for rods specifically shaped and hardened for drilling applications, whereas 7304 covers general-purpose fluid or gas transport piping. Another common error is classifying these under HS code 8207, which covers interchangeable tools for hand tools or machine tools. If the rod is a simple length of steel without a specialized tip or threading for immediate tool use, it belongs in 7228.80. If it has been further worked into a finished drill bit, it moves to Chapter 82.

FAQ

What is the HS code for hollow drill rods?

The HS code for hollow drill rods is 7228.80, which specifically covers hollow drill bars and rods of alloy or non-alloy steel.

How does 7228.80 differ from standard steel tubing?

Standard steel tubing is classified in Chapter 73 (e.g., 7304), while 7228.80 is reserved for steel that meets specific tool-grade requirements and cross-sectional shapes intended for the drilling industry.
