Established in 2000 as Custom Grain Cleaning, Custom Grain & Seed began as a small grain cleaning facility to serve local farmers in the Langdon, N.D. area. In 2012, Custom Grain Cleaning rebranded to Custom Grain & Seed. In doing so, efforts were expanded into canola, corn, soybeans, sunflowers, peas, beans and specialty crops. As well as expanding the crop selection, Custom Grain & Seed also now offers seed treatments, inoculants and biologicals. Custom Grain & Seed has expanded from serving Langdon to serving the entire Midwest with locations in - Langdon, Mandan, Butte, Hettinger and Minot, ND.
Large or small, we have grain cleaning capacity to handle all sizes of seed cleaning needs. We specialize in large-scale cleaning and seed treatments for various crops, including custom blend fungicide and insecticide combinations.
We are a North Dakota Certified Grain Conditioning facility with multiple bulk retail locations throughout Midwestern North Dakota.
