How to choose

  • Start with fit: they already run your kind of product, in your format and package.
  • Open the USDA certificate link on the listing (or look the facility up in the USDA Organic INTEGRITY Database where no link is shown) and confirm the operation is certified and lists products like yours.
  • Ask for minimum order, lead time, and whether they source ingredients or you do.
  • If you need Kosher, SQF, or another certification, ask for the current certificate, not just a logo on a website.
