If you are a US importer or EU distributor evaluating a Chinese medical device manufacturer, the quoted unit price is only half the equation. The other half is regulatory compliance: FDA classification, establishment registration, a 510(k) clearance, UDI marking, and a quality system that meets current Good Manufacturing Practice. Get it wrong and your shipment can be refused at US customs, your clearance delayed for months, or your brand exposed to an FDA warning letter. This guide explains what every buyer should verify before placing a purchase order with a Chinese device factory.
FDA Device Classification: Class I, II, and III
FDA groups medical devices into three risk classes. The class determines how much premarket control applies, and it directly affects which pathway your product must follow before US sale.
- Class I (low risk) — roughly half of device types. General controls apply; most are exempt from premarket review. Examples include bandages, stethoscopes, and manual surgical instruments. Even exempt devices still require establishment registration and device listing.
- Class II (moderate risk) — the largest group of imported devices. Special controls apply, and most require a 510(k) Premarket Notification demonstrating substantial equivalence to a legally marketed predicate device. Examples: infusion pumps, ECG machines, ultrasound systems, surgical drapes, and many dental and monitoring instruments.
- Class III (high risk) — devices that support or sustain human life or are implanted, such as pacemakers, implantable defibrillators, and joint replacements. These require PMA (Premarket Approval), the most rigorous pathway, supported by clinical evidence.
Before you negotiate price, confirm your product code and regulation number. A supplier that says “our device is Class II” without citing the specific regulation is only guessing.
Establishment Registration, Listing, and the US Agent
A foreign manufacturer may not lawfully export devices to the US without completing several administrative steps. First, the establishment must register with FDA annually; the annual registration window runs from October 1 through December 31 for the following calendar year and carries a user fee. Second, every marketed device must be listed, tied to its product code and regulation number. Third, a foreign facility must designate a US Agent — a US-resident person or company who serves as FDA’s local point of contact.
A common red flag is the claim “FDA approved.” FDA does not “approve” Class I or II devices; it clears Class II devices through 510(k) and accepts registration. “FDA registered” is not a safety endorsement. Ask for the registration number and list number, then check them in FDA’s public databases rather than taking a sales call’s word for it.
The 510(k) Pathway for Most Class II Devices
The 510(k) submission demonstrates substantial equivalence on three elements: intended use, technological characteristics, and performance compared with a predicate device. FDA’s review target is about 90 calendar days for a traditional 510(k), although additional information requests routinely extend the real timeline to six to twelve months.
As the buyer, you are often the applicant of record unless the manufacturer already holds the clearance. Verify three things: whether the factory holds an existing 510(k) for your exact product, the 510(k) number, and whether the cleared specifications match yours. A supplier offering “we will get 510(k) for you” without a named predicate device, biocompatibility test reports, or electrical-safety documentation is exposing you to significant delay and cost.
UDI and Quality System Requirements to Verify
Unique Device Identification (UDI), under 21 CFR Part 830, requires a device identifier (DI) plus a production identifier (PI) on the label and in the FDA GUDID database. Ask to see the actual UDI carrier — barcode, QR code, or RFID — and the GUDID entry. Class II UDI compliance deadlines have long since passed, so a factory without UDI capability in 2026 is behind.
ISO 13485:2016 is the international quality management standard for medical devices. Critically, since February 2, 2026, FDA’s Quality Management System Regulation (QMSR) has aligned 21 CFR Part 820 directly with ISO 13485:2016. Request a current ISO 13485 certificate, verify it on the notified body’s website, and confirm that the certified scope actually covers your product family. Also ask for device master file (DHF) excerpts, complaint-handling procedures, and lot traceability records.
Common Class II Sourcing Risks and How to Mitigate Them
- Scope mismatch: the factory holds ISO 13485 for sterile syringes, not for your diagnostic device. Verify scope line by line.
- Registration without clearance: a “FDA-registered” Class II device that lacks 510(k) cannot lawfully be sold in the US.
- Hidden subcontracting: many brands outsource molding, sterilization, or final assembly. Confirm that the registered establishment is the one actually manufacturing, and that ethylene-oxide or other sterilization is validated.
- Labeling gaps: Chinese-language labels alone will be refused. US labels must meet 21 CFR 801 and carry UDI.
- Missing biocompatibility data: skin-contact or body-contact devices need ISO 10993 testing.
Mitigate all of these by commissioning a third-party GMP/ISO 13485 factory audit, verifying the 510(k) number in FDA’s database, and writing regulatory deliverables — certificates, test reports, and 510(k) status — directly into your purchase contract.
