Import Tips
• Provide mill test certificates verifying beryllium copper alloy composition per subheading note (a)-(d) exclusions
• Measure and document exact thickness to confirm >5mm classification; thinner sheets shift to 7409.90.10.50
• Comply with REACH and TSCA regulations for beryllium content due to toxicity risks
