Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If semi-finished (not rolled into bars)
Semi-finished alloy steel products classify earlier in Chapter 72.
If final drill collar component
Machined oilfield drill collars become parts of drilling machinery in Chapter 84.
If high-strength steel certified
Meets yield point specs in U.S. note (a), potentially different statistical reporting.

Import Tips & Compliance
• Provide chemical analysis showing controlled alloy levels distinguishing from carbon steel
• Confirm rectangular/square dimensions measured across widest point exceeds 228 mm
• Declare intended forging use but classify based on current hot-rolled condition only
