Last updated: August 2026 dataWhey protein concentrates (WPC) and other whey derivatives are critical inputs for sports nutrition, infant formula, and processed food manufacturing, making this heading commercially significant across multiple end-use sectors. Canada and Denmark lead US imports, with the Netherlands and France also prominent — reflecting the concentration of large-scale cheese and whey processing capacity in those countries. The US schedule separates whey protein concentrates (0404100500) from modified whey (0404100850 and 0404101500) and from standard fluid and dried whey, with dried whey further subdivided by TRQ eligibility under US additional note 12. USDA FSIS admissibility clearance is required for all entries.

Whey protein concentrate (0404100500) is whey that has been processed to increase its protein content relative to other solids, typically through ultrafiltration, but retains its fundamental whey character. Modified whey (0404100850 and 0404101500) refers to whey that has been chemically or enzymatically altered — for example, through hydrolysis or demineralization — changing its functional properties. The distinction matters because the two lines carry different duty treatments.
US additional note 12 establishes a quantity limit for dried whey at a lower in-quota duty rate. Line 0404105010 covers dried whey entered under a license issued pursuant to that note, while 0404105090 covers licensed entries that are NESOI, and 0404109000 covers all other dried whey outside the note 12 framework. Importers seeking in-quota treatment must obtain the applicable import license before shipment. Consult a licensed customs broker or USDA for current licensing procedures.
