For commercial or home? For commercial, it still needs to be processed/bottled in a commercial kitchen, unless your state (area) allows home bottling of spices (some allow spices, jams, and other snacks). Plastic spice bottles need to be EtO sterilized or irradiated. Ingredients must be 100% dry. Any water or liquid and you get into environments for botulism. If it is totally dry in a sterile jar, then you really don't need to do much more. Air tight seal keeps it fresher, and tamper proof seal is a professional touch. Does this help?
