Inconel 625 Nickel Alloy Sheet
Inconel 625 is a high-performance nickel-chromium-molybdenum alloy sheet used in aerospace and chemical processing for its corrosion resistance. This hot-rolled sheet, not cold-formed, falls under HTS 7506.20.30.00 as a nickel alloy plate or sheet. Thickness typically ranges from 0.5mm to 25mm for industrial applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-formed or cold-rolled
Cold-formed nickel alloy sheets fall under the specific cold-formed subheading, changing duty treatment.
If alloy steel rather than nickel alloy
If iron content exceeds 50%, it classifies as alloy steel flat-rolled products under Chapter 72.
If imported as heat exchanger parts
Specific end-use as machinery parts takes precedence over material classification.

Import Tips & Compliance
• Obtain mill test certificates (MTC) verifying chemical composition and mechanical properties to meet ASTM B443 standards
• Declare exact alloy grade and thickness; misclassification as cold-formed can trigger re-assessment under 7506.20.40
• Ensure proper packing to prevent surface damage, as nickel alloy sheets are prone to scratching during transit
