Incoloy 800H Heat Exchanger U-Tube
Cold-rolled seamless Incoloy 800H U-tube, 17.5 mm outside diameter, bent into a U-shape for use in tubular heat exchangers in nitric acid plants. The nickel-iron-chromium alloy provides high-temperature corrosion resistance, and the cold-rolling process gives precise dimensions. This product falls under tariff item 7304.41.00 as a seamless stainless steel tube, cold-drawn or cold-rolled, of circular cross-section.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tube is not cold-drawn or cold-rolled (e.g., hot-finished)
Hot-finished seamless stainless steel tubes fall under a different tariff item within the same heading.
If the tube is of alloy steel other than stainless
Alloy steel tubes are classified separately from stainless steel tubes.
If imported as a part of a heat exchanger
Parts of heat exchangers may be classified under Chapter 84 if they meet the criteria for parts.

Import Tips & Compliance
• Ensure the Incoloy 800H alloy is documented as stainless steel under Canadian classification; provide a mill certificate showing chemical composition
• Verify the outside diameter (17.5 mm) and seamless construction to confirm classification under 7304.41.00
• Consider whether the U-bending constitutes further working that might affect classification
