Grinders For Cannabis Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

BLACK+DECKER is the best-performing grinders for cannabis brand in July 2026, moving 10,000 units across 1 ASIN for 29.6% of Top 10 volume. Amazon Basics follows with 8,000 units (23.7%), ahead of RAW on 5,000 units (14.8%).

With 9 brands splitting the Top 10 and 68.0% 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 $4.15 to $25.99, 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: B09B79YK1C booked 800 units at $24.99, with ▲ 14.3% MoM change. On the growth side, B0G48FKGZF leads positive momentum with ▲ 500.0% MoM growth on 600 units, with B0D2KTF8FJ close behind at ▲ 500.0% MoM on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
