Import Tips & Compliance
• Confirm the tin content is below 3% by weight to maintain brass classification; provide an alloy certificate
• Ensure the foil is unbacked and measure thickness accurately, as the 0.15 mm threshold is critical
• Consider whether the end-use in condensers might require additional regulatory compliance (e.g
• pressure equipment directives)
