Seamless Admiralty Brass Tube from Canada
Admiralty brass tubes (C44300 alloy) are seamless copper-zinc-tin alloy pipes used primarily in heat exchangers and condensers for their excellent corrosion resistance in seawater. Classified under HTS 7411.29.10.00 as seamless tubes of copper alloys other than those specifically excluded. Meets subheading note (a) for brass alloys where zinc predominates.

Import Tips
• 1
• Provide mill test certificates confirming seamless construction and exact alloy composition per ASTM B111 to avoid reclassification as welded. 2
• Declare outer diameter and wall thickness accurately as statistical suffixes may apply. 3
• Ensure no zinc content exceeds limits that would shift to nickel silver classification
