Starting a Freeze-Drying Food Business
Starting a freeze-drying food business in the United States means working through a decision framework, not collecting one national permit. Product type, location, sales channel, interstate versus intrastate sales, facility type, and your state all change what applies. This page gives no national yes or no answers, because in the U.S. there usually is not one.

The decision framework
Answer each question before you look for guidance, because they change which authority and rules apply:
- Product type: Human food or animal food? The federal tracks differ: most human foods and animal foods fall under FDA, while certain meat, poultry and processed egg products fall under USDA/FSIS.
- Location: Home, commercial facility, or shared kitchen? Home production is a state cottage-food question, not a federal answer.
- Sales channel: Direct, online, wholesale, retail, or farmers market? The channel changes cottage-food eligibility and state licensing.
- Intrastate vs interstate: Selling only within your state versus across state lines can add federal obligations and destination-state rules.
- Facility type: A dedicated commercial facility may face FDA facility registration, state processing licensing, and local health and building requirements.
- State: Your state's cottage-food law, licensing and pet-food registration are decided state by state, never nationally.
- Animal vs human food: Pet food adds a state-registration layer on top of federal animal-food rules.
Federal, state and local are different layers
A federal answer alone is often incomplete. Confirm the federal layer with FDA or FSIS as applicable, and the state and local layers with your state's agriculture and public-health agencies and your local jurisdiction.
Where to continue
Follow the framework pages in this section: human food manufacturing, cottage food, home-based, pet food, FDA food facility registration and commercial facility.

Common questions
Is there one US permit to start a food business?
No. The United States layers federal, state and local requirements, and which ones apply depends on your product, place and channel.
Can I start and see later?
You can investigate first, but several obligations (facility registration, licensing, labeling) are tied to specific triggers. Confirm the layers before you sell.
