Several manufacturers and suppliers offer 8-gallon food-grade plastic buckets, including BASCO, ePackageSupply, MJS Packaging, and The Cary Company, specializing in HDPE/PP materials, FDA compliance, and options like lids, handles, and bulk ordering, with some offering custom printing or being U.S.-based for quality assurance. Companies like Hudson Exchange, www.plastic-bucket-manufacturers.com, and The Beverage People also list these sizes, catering to various needs from home use to industrial applications, ensuring food-safe storage solutions. 

When choosing, check for FDA compliance, material (HDPE/PP), availability of lids, and if they meet your needs for quantity, color, and custom printing.
