Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the duct tube is imported as a component of a complete ventilation or air-handling system.
Parts of fans or ventilation systems may be classified under Chapter 84 rather than as base metal tubes.
If the tube is cut, shaped, or fitted with ends to serve a specific function (e.g., a duct connector).
Articles of aluminum, other than tubes, may fall under this heading when they have assumed the character of finished articles.

Import Tips & Compliance
• Ensure the aluminum content is at least 99% and that other elements (e.g
• Fe+Si, Cu, Mg) stay within the limits in subheading note 1(a) to qualify as 'not alloyed'
• Keep mill certificates or lab analysis to prove composition if requested by CBSA
• Verify whether the duct tube is considered a part of a ventilation system, which could affect classification
