Milling stage is the defining classification criterion here: rice that has had its bran layer partially or fully removed — whether polished or not — falls under this heading rather than the brown-rice or paddy headings. The US schedule is among the most detailed in Chapter 10, with 13 active 10-digit lines that cross-cut parboiling status, grain length (long, medium, short, mixed), aromatic variety (jasmine at 1006309057, basmati at 1006309059), and organic certification (1006309015). Thailand and India lead US supply of milled rice, together accounting for the bulk of aromatic and parboiled volumes. All shipments are subject to FDA admissibility review; importers should verify that foreign mills appear on FDA's import alert clearance lists before booking cargo.
