What FDA registration means for a contract manufacturer
Companies that manufacture finished medical devices, or perform certain operations on them, register their establishment with the FDA and list the devices involved. Registration doesn't mean the FDA has approved the company; it means the company is known to the FDA and can be inspected.
For a buyer, registration is a useful signal: it tells you the shop has operated under FDA expectations, understands device history and traceability records, and has likely hosted customer and regulatory audits.
What ISO 13485 means
ISO 13485 is the quality management standard written specifically for medical devices. It covers document control, supplier management, risk-based processes, traceability, complaint handling, and corrective and preventive action (CAPA).
Since the FDA's Quality Management System Regulation (QMSR) took effect in 2026, the U.S. rules incorporate ISO 13485 by reference, so the two now line up much more closely than before.
"Conforms to" vs. "certified to"
A shop can run a quality system that conforms to ISO 13485 without holding a certificate from a registrar, or it can be audited and certified by an accredited third party. Both can be legitimate. What matters is that the supplier is precise about which one applies, and can show you the quality manual, procedures, and records either way.
Questions to ask any medical machining supplier
- How long have you been FDA registered, and have you hosted OEM supplier audits?
- Is your quality system certified to ISO 13485 or does it conform to it? Can I see the quality manual?
- What ships with every order: certificate of conformance, material certs, first article inspection, lot traceability?
- How do you control outside processes like passivation, heat treat, and anodizing?
- How do you handle a nonconformance, and how quickly will I hear about it?
- Can you support process validation (IQ/OQ/PQ) when my program needs it?
The bottom line
Certificates are a starting point, not the finish line. Visit the shop, look at real inspection records, and talk to the people who will make your parts. A good supplier will welcome it.
Frequently asked questions
Does FDA registration mean a machine shop is FDA approved?
No. Registration lists the establishment with the FDA and subjects it to inspection. The FDA clears or approves devices, not suppliers.
Is ISO 13485 required for medical device suppliers?
It depends on the supplier's role and the OEM's requirements. Many OEMs require a quality system that meets ISO 13485, and U.S. regulations now incorporate the standard.
