Best 21 Gallon Trash Bags Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Amazon Basics is the best-performing 21 gallon trash bags brand in July 2026, moving 110,000 units across 2 ASINs for 47.8% of Top 10 volume. Glad follows with 80,000 units (34.8%), ahead of Hefty on 40,000 units (17.4%).
With 3 brands splitting the Top 10 and 100.0% 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 $14.96 to $18.47, which frames the price band a competing listing has to justify.

Trending 21 Gallon Trash Bags Products — Growth Leaders & New Top 10 Entrants
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, 3 ASINs forced its way in: B092VPGJB9 booked 40K units at $17.33, with ▲ 300.0% MoM change.
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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
