HS Code 72.28 – Alloy steel bars, rods, shapes and sections; hollow drill bars and rods, of alloy or non-alloy steel

HS code 7228 is a 4-digit heading in the Harmonized System that covers: Alloy steel bars, rods, shapes and sections; hollow drill bars and rods, of alloy or non-alloy steel. Heading 7228 is a comprehensive classification for "Alloy steel bars, rods, shapes and sections; hollow drill bars and rods, of alloy or non-alloy steel." This heading is crucial for trade professionals dealing with a wide array of specialized steel products used across heavy industries. Its scope is broad, covering various forms of alloy steel (bars, rods, structural shapes, and sections) that are not specifically covered elsewhere, particularly not in irregularly wound coils (like 7227). A unique and important inclusion is "hollow drill bars and rods," which, exceptionally, can be made of either alloy or non-alloy steel, recognizing their specialized function in drilling operations. Sub-categories are diverse, encompassing different alloy compositions (e.g., tool steel, high-speed steel, stainless steel bars not specified elsewhere, structural alloys), various manufacturing processes (hot-rolled, cold-drawn, forged, machined), and a multitude of cross-sections (round, square, hexagonal, angles, channels, H-beams). This detailed classification is vital for trade compliance, as it directly impacts applicable tariffs, anti-dumping measures, and specific industry standards for sectors like construction, mining, aerospace, and general machinery manufacturing. The historical development of specialized steels for high-performance applications underscores the importance of this heading. Within Chapter 72 (Iron and Steel), heading 7228 serves as a significant 'other' category for processed alloy steel forms, distinguishing them from non-alloy steel equivalents (e.g., 7214, 7215, 7216) and the coiled products of 7227, while carving out a specific provision for hollow drill bars.

Stainless steel bars (straight lengths), tool steel rods for machining, high-strength alloy steel structural beams, cold-drawn alloy steel hexagonal bars, forged alloy steel shafts, high-speed steel tool blanks, wear-resistant alloy steel sections for mining, heat-treated alloy steel rounds, chrome-molybdenum alloy steel bars for aerospace, nickel-alloy steel rods for corrosion resistance, hollow drill rods for mining, non-alloy steel hollow drill bars for tunneling, alloy steel angles for heavy fabrication, specialized alloy steel channels, precision ground alloy steel bars, carburizing alloy steel bars, quenched and tempered alloy steel rods, alloy steel rebar (straight lengths, if alloyed), alloy steel flat bars (other than flat-rolled products), alloy steel square bars, alloy steel half-round bars, alloy steel railway track components (if alloyed and in bar/rod form).

A common misclassification involves confusing 7228 with non-alloy steel equivalents found in headings like 7214, 7215, or 7216. The key differentiator is the 'alloy' content, requiring careful verification of alloying element percentages. Another frequent error is distinguishing 7228 from 7227; 7228 covers bars and rods *not* in irregularly wound coils, and also includes shapes and sections, whereas 7227 is specifically for hot-rolled bars/rods in coils. Finally, products can sometimes be mistaken for tubes or pipes (Chapter 73), but 7228 primarily covers solid or specific hollow (drill) bars/rods and structural sections, not general tubular products.

In 2025, the top exporters of HS code 7228 in UN Comtrade data were China ($2.8B, 26% of world exports), Germany ($1.2B) and Italy ($781M). World exports came to about $11.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 7228 in UN Comtrade data were Germany ($1.3B, 11% of world imports), Mexico ($705M) and the United States ($611M). World imports came to about $11.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 7228 is a 4-digit heading under Chapter 72 of the Harmonized System. The first 2 digits (72) identify the chapter, and digits 3-4 (28) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
