Reported U.S. chip potato shipments fell sharply during August, with movement over the four-week period running 36.9% below the corresponding period in 2025.

Shipments totalled 2.294m cwt, 1.339m cwt below year-earlier levels, according to North American Potato Market News data compiled for the Michigan Potato Industry Commission.

Michigan recorded the largest reduction, with reported shipments down by 330,000 cwt compared with the same period last year. Wisconsin movement was 221,000 cwt lower, while shipments from the West Coast region declined by 213,000 cwt.

The Midwest reported a 130,000-cwt reduction, followed by Pennsylvania at 100,000 cwt, the Mid-Central region at 80,000 cwt, Maine at 78,000 cwt and the Southwest at 67,000 cwt.

No reporting region recorded an increase in chip potato movement during the four weeks compared with 2025.

Season-to-date reported shipments of new-crop chip potatoes were running 13.2% behind the previous year’s pace at the beginning of September.

The September 2 market report did not attribute the decline to a single cause.

Separate table-potato data showed U.S. packers shipped 1.407m cwt during the week ending August 29, compared with 1.424m cwt during the equivalent week of 2025.
