Import Tips
• Verify protein purity exceeds 90% with lab certificates to confirm classification as isolate under Chapter 35
• Include dairy origin documentation to avoid reclassification under Chapter 4 if residual lactose content is high
• Label accurately for FDA nutritional claims; mislabeling can lead to holds at customs
