Chipper Knife Steel Hot-Rolled Strip 1.2mm Thick
Flat-rolled alloy steel strip of 1.2mm thickness and 150mm width, hot-rolled and not further worked, specifically formulated as chipper knife steel with 0.5% carbon, 8.5% chromium, and 1.5% molybdenum. It falls under HTS 7226.91.0500 because it precisely matches the chapter note definition for chipper knife steel in the specified elemental composition range and is not further worked beyond hot-rolling.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If subjected to polishing, coating, or other surface treatments
Chapter note defines 'further worked' surface treatments like polishing or coating that move classification from hot-rolled (7226.91.05) to further worked tool steel (7226.91.15).
If width 600mm or more
Width threshold changes heading from 7226 (under 600mm) to 7225 (600mm+), even for identical chipper knife steel composition.
If further worked beyond hot-rolling, like cold-rolled
Cold-rolled or otherwise worked alloy steel bars/rods fall under 7228, distinct from hot-rolled flat products in 7226.

Import Tips & Compliance
• Provide mill test certificate confirming exact elemental composition matches U.S
• Note (f) for chipper knife steel, including carbon 0.48-0.55%, Cr 7.25-8.75%, Mo 1.25-1.75%
• Verify product is hot-rolled only with no further working like polishing or coating to avoid reclassification under 7226.91.15 or 7226.92
• Ensure width under 600mm and document as 'not further worked' to prevent common pitfalls of duty reassessment
