Baking Soda Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Arm & Hammer is the best-performing baking soda brand in July 2026, moving 170,000 units across 6 ASINs for 81.0% of Top 10 volume. Amazon Grocery follows with 10,000 units (4.8%), ahead of Clabber Girl on 10,000 units (4.8%).

With 5 brands splitting the Top 10 and 90.5% 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 $0.99 to $7.83, 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: B09NRGMTYP booked 10K units at $0.99. On the growth side, B0FJ7S86SD leads positive momentum with ▲ 900.0% MoM growth on 10K units, with B07BNXB9X9 close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
