7228.80.00.00 - Hollow drill bars and rods

HTS Code 7228.80.00.00 specifically classifies hollow drill bars and rods. These are semi-finished or finished products manufactured from iron or steel, characterized by a hollow center designed for use in drilling operations. Their primary function is to transmit rotational force and, in some applications, flushing fluid to a drill bit.

This category is distinct from other "Other bars and rods" within HTS 7228. For instance, while sibling categories like 7228.10.00 cover bars and rods of high-speed steel, and 7228.20 addresses silico-manganese steel, 7228.80.00.00's defining characteristic is its hollow construction specifically for drill bar applications, irrespective of whether it's made from alloy or non-alloy steel. It also differentiates itself from bars and rods that are merely hot-rolled, hot-drawn, extruded, forged, or cold-formed/finished, as the hollow design for drilling is the primary classification criterion.

As a leaf node, 7228.80.00.00 does not have further subcategories. Therefore, classification at this level relies on confirming the product is indeed a bar or rod with a hollow center, intended for use in drilling machinery. Factors such as diameter, wall thickness, and the type of steel alloy used would fall under the broader scope of HTS Chapter 72, but the distinguishing feature for this specific code is the hollow drill bar form.
