What certifications should I look for in a household cleaner co-packer?

Look for ISO 9001 quality management certification, EPA Safer Choice partnership status if you want an eco-positioned product, and NSF certification if you are targeting food-service or institutional channels. For facilities handling bleach or acid formulas, confirm they hold the appropriate OSHA Process Safety Management compliance and secondary containment standards.
