Standard International Trade Classification
U.S. imports of Other Natural Milk Constituent Products (N.E.S.) (SITC 02249) totaled $25.4M in September 2026, imported from 23 countries.
Importers of Other Natural Milk Constituent Products (N.E.S.) paid $3.2M in duties in September 2026, an average duty rate of 13.04% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Other Natural Milk Constituent Products (N.E.S.) imports of $25.4M in September 2026 ran 26% below the year-to-date monthly average of $34.1M.
Last updated: September 2026 dataResidual dairy products consisting of natural milk constituents that do not fit more specific headings — such as certain milk protein concentrates, lactose-reduced dairy fractions, or specialized dairy ingredient blends — fall under this not-elsewhere-specified category. Classification here is often the result of a deliberate analysis confirming the product does not meet the specifications of whey, butter, cheese, or other defined dairy headings, making accurate technical documentation especially important. USDA FSIS admissibility requirements apply to all natural milk constituent products, and importers should be prepared to provide detailed compositional analysis to support the NES classification. Because this heading serves as a catch-all, CBP scrutiny of entry documentation tends to be higher than for more precisely defined dairy categories.

Products such as milk protein concentrates (MPC), casein-whey blends, lactose, and other fractionated dairy ingredients that do not meet the specific definitions of whey, butter, cheese, or other named dairy headings may fall here. The NES designation means classification is by exclusion, so importers must be able to demonstrate why the product does not belong in a more specific heading.
Because NES headings are residual categories, CBP may question whether a product truly lacks a more specific classification. Importers should prepare a detailed compositional analysis (protein, fat, lactose, moisture percentages), a description of the manufacturing process, and, if available, a binding ruling or prior classification decision. Consulting a licensed customs broker before the first shipment is strongly advisable to reduce the risk of reclassification and associated duty adjustments.
