HS Code for Cold-finished alloy steel bars

Cold-finished alloy steel bars are classified under HS code 7228.50 because they meet the criteria for 'other alloy steel' as defined in Chapter 72, Note 1(f), and have undergone a cold-finishing process. The Harmonized System distinguishes between non-alloy, stainless, and other alloy steels based on chemical composition. For a product to be classified here, it must contain alloying elements such as chromium, manganese, or molybdenum in percentages exceeding the thresholds set in the legal notes. The 'cold-finished' designation refers to bars that, after hot-rolling, have been subjected to further processing at room temperature, such as cold-drawing, grinding, or polishing. This process improves dimensional accuracy, surface smoothness, and mechanical strength. Under the General Rules of Interpretation (GRI) 1 and 6, the product is specifically directed to heading 7228, which covers bars and rods of other alloy steel, and subheading 7228.50, which is reserved for those that are cold-formed or cold-finished.

Products Included

• Cold-drawn alloy steel rounds (e.g., 4140, 4340, 8620 grades)
• Centerless ground alloy steel bars
• Polished alloy steel hexagonal and square bars
• Cold-finished alloy steel flats for tool and die applications
• Turned and polished alloy steel shafting

Common Misclassification

This code is frequently confused with HS code 7228.30, which covers alloy steel bars that are only hot-rolled, hot-drawn, or extruded. The primary difference lies in the surface finish and tolerances; cold-finished bars have a much smoother appearance. Another common error is misclassifying these as non-alloy steel under 7215.50. To avoid this, a mill test report (MTR) must be consulted to verify that the alloying elements meet the minimum requirements of Chapter 72, Note 1(f). Furthermore, if the steel contains more than 1.2% carbon or 10.5% chromium, it may be classified as stainless steel under heading 7222.

FAQ

What is the HS code for cold-finished alloy steel bars?

The primary HS code for these products is 7228.50, which specifically covers bars and rods of other alloy steel that are cold-formed or cold-finished.

How do I distinguish between cold-finished and hot-rolled alloy bars for customs?

Cold-finished bars typically exhibit a bright, smooth surface and precise dimensions, whereas hot-rolled bars (7228.30) have a dark, oxidized scale and looser tolerances. Customs authorities often require technical specifications or MTRs to confirm the finishing process.
