A fat content exceeding 6% by weight would place the product outside this heading and into a higher-fat classification, which may carry a different duty rate and separate TRQ treatment. If CBP laboratory testing at the port produces a result above the 6% ceiling, the entry would need to be amended to reflect the correct classification, potentially resulting in additional duties. Importers should build a testing margin into their quality control process to avoid borderline results.

Yes. FDA's standards of identity for milk specify the fat content thresholds that determine how a product may be labeled — for example, 'reduced fat milk' must contain a specific fat percentage. Imported fluid milk must comply with these standards before it can be sold in US commerce, and labels must accurately reflect the fat content. Non-compliant labeling can result in detention or refusal at the port of entry. Importers should confirm label compliance before shipment.
