Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 1% milk solids or residual whey components
Products retaining significant dairy characteristics like lactose fall under whey and dairy products in Chapter 4.
If when blended with flavors, sweeteners, or sold as ready-to-mix food supplement
Food preparations containing protein isolates are classified in Chapter 21 based on end-use as consumable mixtures.
If derived from milk but not isolated to high purity levels
Less refined milk albumins and protein substances remain in heading 3502 of this chapter.

Import Tips & Compliance
• 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
