FDA requirements for machinery and equipment fall into two categories: Food machinery focuses on compliance regarding food-contact materials (21 CFR 174–179; contact surfaces must use 304/316 stainless steel and food-grade seals, and undergo migration testing; the FDA does not issue “certificates of certification”—compliance relies on material conformity and self-declaration); Medical equipment requires FDA registration and listing, a 510(k) premarket notification (for Class II devices), and a quality management system compliant with ISO 13485 or 21 CFR 820.
I.
FDA Requirements for Food Machinery
The FDA regulates food machinery based on food-contact materials (FCM) and sanitary design: Contact surface materials (conveyor belts, seals, containers, valves, piping) must comply with 21 CFR Parts 170–199 (commonly 304/316 stainless steel, food-grade rubber, PTFE, PP); Migration testing (new materials or coatings require migration test data: total migration under intended conditions of temperature, time, and medium); Sanitary design (contact surfaces must be cleanable and prevent cross-contamination; 21 CFR 117)—the FDA does not issue certificates; compliance is established through manufacturer self-declaration supported by test reports.
II. Three Compliance Pathways
First, 21 CFR Listing (substances and uses included in the lists under Parts 174–178); second, FCN Notification (Food Contact Notification for new substances; valid only for the notifying manufacturer and their customers); third, GRAS/Prior Sanction/TOR Exemption (Generally Recognized As Safe / Threshold of Regulation exemption)—materials commonly used in equipment (e.g., 304/316 stainless steel, food-grade PP/PTFE) are inherently compliant, whereas new coating materials require an FCN.
III.
FDA Pathways for Medical Devices
Registration and Listing: FDA registration for foreign manufacturers + product listing (21 CFR 807); 510(k): Premarket Notification for Class II devices (e.g., steam sterilizers under 21 CFR 880.6880; submission of a K-number); Quality System: ISO 13485/21 CFR 820 (documented QMS); Class III: PMA (Premarket Approval) for high-risk devices—the FDA threshold for medical devices is significantly higher than that for food machinery.
IV.
Common Misconceptions About FDA Certification
First, “FDA Certification Certificates” do not exist (there are only registration numbers, test reports, or 510(k) clearances); second, food machinery does not require FDA device approval (material compliance is sufficient); third, FDA registration is not the same as certification (registration is simply an enterprise filing); fourth, third-party reports (FDA test reports from SGS, BV, etc., serve as clearance passes)—it is important to distinguish between “FDA registration (filing)” and “FDA compliance (materials/testing).”
V. Checklist for Overseas Buyers
First, food machinery: requires a declaration of material compliance and migration test reports (confirming 304/316 stainless steel for contact surfaces); second, medical equipment: requires a 510(k) number/registration number and ISO 13485 certification; third, FDA registration number (facility registration); fourth, hygienic design (confirmation of cleanable design); and fifth, do not confuse CE with FDA (CE applies to the EU, while FDA applies to the US)—for food machinery, FDA compliance entails material compliance and a self-declaration (no certificate is issued), whereas for medical equipment, it involves registration, 510(k) clearance, and ISO 13485 certification.
Buyers should request the appropriate documentation based on the specific equipment type.
