Clad Aluminum Alloy Heat Exchanger Plate from China
A rectangular clad aluminum alloy plate exceeding 0.2 mm thickness, featuring a core of 3003 alloy bonded with a 4343 brazing layer on both sides for heat exchanger applications. It falls under HTS 7606.12.60.00 as a clad aluminum alloy plate or sheet in rectangular form. The cladding enhances corrosion resistance and brazing performance in automotive and HVAC systems.

Import Tips
• Verify alloy composition meets subheading note (b) definition with aluminum predominating and other elements exceeding specified limits; provide mill test certificates
• Confirm cladding process documentation as diffusion-bonded layers, not merely coated, to avoid reclassification to painted/coated plates under 7606.12.30
• Ensure thickness >0.2mm measured per ASTM standards; common pitfall is mismeasuring clad total vs core thickness
