Rice Flour Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

King Arthur is the best-performing rice flour brand in July 2026, moving 24,000 units across 3 ASINs for 63.2% of Top 10 volume. Bob's Red Mill follows with 6,000 units (15.8%), ahead of Jovial on 2,000 units (5.3%).

With 6 brands splitting the Top 10 and 84.2% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $6.20 to $11.49, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0DM2DFG4N booked 2K units at $6.99, with ▲ 566.7% MoM change. On the growth side, B0DM2B3MG6 leads positive momentum with ▲ 400.0% MoM growth on 500 units, with B000VK5VEO close behind at ▲ 300.0% MoM on 200 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
