Thule Cargo Box Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Asinking is the best-performing thule cargo box brand in July 2026, moving 4,000 units across 3 ASINs for 34.8% of Top 10 volume. FIVKLEMNZ follows with 3,000 units (26.1%), ahead of MIDABAO on 1,000 units (8.7%).

With 8 brands splitting the Top 10 and 69.6% 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 $70.99 to $109.99, 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, 2 ASINs forced its way in: B0BCW2CD2R booked 3K units at $109.99. On the growth side, B0GL6HFNLT leads positive momentum with ▲ 300.0% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
