How do I find the FDA classification for my specific device?

Start with the FDA product classification database. Search by device name or keyword, then confirm the classification by reading the applicable 21 CFR section (Parts 862 through 892). For novel devices, combination products, or software as a medical device, a regulatory consultant should conduct the formal classification analysis, as the database alone may not resolve ambiguous cases.

What is the difference between a Class I and Class II device?

Class I devices are subject only to general controls and most are exempt from premarket submission. Class II devices are subject to general controls plus special controls (performance standards, guidance documents, or other measures specific to the device type) and most require 510(k) clearance before marketing. The key practical difference for most companies is the premarket submission requirement: Class I exempt devices can go to market after registration and listing, while most Class II devices need a 510(k) clearance letter first.

Can a device's classification change?

Yes. A device type can be reclassified upward or downward through the FDA's regulatory process. A Class III device type can be reclassified to Class II if the FDA determines that general controls plus special controls are sufficient (Section 513(e) of the FD&C Act). De Novo classification is also a form of new classification for novel devices. Reclassification requests are published in the Federal Register and go through notice-and-comment rulemaking. Individual device clearances or approvals are not changed by reclassification, but future submissions for that device type will follow the new class.

Does a Class I device still need to register with the FDA?

Yes. Establishment registration and device listing requirements under 21 CFR Part 807 apply to manufacturers, importers, and initial distributors of most medical devices regardless of class, including Class I exempt devices. Registration is an administrative requirement; it is not a marketing authorization, and "FDA registered" should not be used as a marketing claim that implies FDA review of the device.

What is a product code and why does it matter?

A product code is a three-letter identifier assigned to a device type in the FDA's classification system. It appears in 510(k) clearance letters and in the FDA's product classification and 510(k) databases. Product codes matter operationally because they let you search for competitive clearances, monitor predicate landscape changes, and direct distributors and procurement contacts to the FDA's public record. They also appear in device listings, which is another reason to confirm your product code early in the regulatory process.

Can the same technology have different classifications for different intended uses?

Yes, and this is one of the most important classification principles for product development teams to internalize. Intended use is a core input to classification. A software application that monitors a person's heart rate for general wellness may be outside FDA's device jurisdiction as a low-risk general-wellness product, while a software application that uses the same signal to detect atrial fibrillation and inform clinical decisions is regulated as a medical device (commonly Class II). The FDA's Digital Health Center of Excellence and guidance on Software as a Medical Device (SaMD) describe how intended use shapes classification for software-based products.

Medical Device Classification: Class I, II, and III Explained

Direct answer: The FDA classifies medical devices into three classes based on risk and the controls necessary to provide reasonable assurance of safety and effectiveness. Class I devices (lowest risk) are subject to general controls only; most are exempt from premarket submission. Class II devices (moderate risk) add special controls and typically require 510(k) clearance. Class III devices (highest risk) require Premarket Approval (PMA), where the FDA independently evaluates safety and effectiveness. Device class determines your regulatory pathway, your evidence burden, and the marketing term you can legally use. (As of July 2026.)

The class your device falls into is not an administrative technicality. It determines whether you need to submit anything to the FDA before marketing, what evidence you need to generate, how long the regulatory process will take, and what you can legally say about your device once it reaches market.

Most founders learn their device's class through their first regulatory consultant engagement. But marketing leaders benefit from understanding classification too, because class drives the pathway that drives the launch timeline that drives everything downstream: product page copy, trade show plans, sales deck claims, investor communication about regulatory milestones.

This article explains how the three-class system works, what each class requires, and how classification connects to the marketing program.

The Statutory Basis for Device Classification

The three-class framework was established by the Medical Device Amendments of 1976, which added device regulation to the Federal Food, Drug, and Cosmetic Act. The classification authority and principles are codified in Section 513 of the FD&C Act (21 U.S.C. 360c, https://www.law.cornell.edu/uscode/text/21/360c).

The statute defines classification as based on the amount of regulation necessary to provide reasonable assurance of safety and effectiveness, given the intended use of the device and the risk it presents. Three levels of regulatory control correspond to three device classes.

The implementing regulations for device classification procedures are in 21 CFR Part 860 (https://www.law.cornell.edu/cfr/text/21/part-860). Specific device classifications are listed in 21 CFR Parts 862 through 892 (https://www.law.cornell.edu/cfr/text/21/chapter-I/subchapter-H), organized by medical specialty panel. These regulations list product codes, device names, classification classes, and any 510(k) exemptions or special controls applicable to each device type.

The FDA also maintains a searchable product classification database at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfPCD/classification.cfm, which is the fastest starting point for looking up any specific device type.

Class I: General Controls

Risk level: Lowest.

What "general controls" means: General controls are the baseline requirements that apply to all FDA-regulated medical devices regardless of class. They include: establishment registration (21 CFR Part 807), device listing (21 CFR Part 807), the Quality Management System Regulation (21 CFR Part 820), which as of its February 2, 2026 compliance date incorporates ISO 13485:2016 by reference, labeling requirements (21 CFR Part 801), prohibition against adulterated and misbranded devices (21 U.S.C. 331, 351, 352), and Medical Device Reporting (MDR) for adverse events (21 CFR Part 803).

Premarket submission: Most Class I devices are exempt from 510(k) premarket notification. The exemption is granted by the FDA through the classification regulations in Parts 862 through 892, where the relevant CFR section for a device type will either include "exempt" or not include 510(k) as a requirement. Being exempt does not mean unregulated; general controls apply regardless.

Examples: Bandages, examination gloves, tongue depressors, elastic bandages, many non-powered surgical instruments, dental floss.

Marketing implication: A Class I exempt device has not been reviewed or cleared by the FDA before marketing. Do not describe it as "FDA cleared," "FDA approved," or "FDA reviewed." The accurate disclosure, if any regulatory status claim is made, is that the device is a Class I device exempt from FDA premarket notification requirements. Many Class I companies choose to say nothing about regulatory status in consumer marketing and instead focus on materials, performance, and clinical utility.

Class II: Special Controls

Risk level: Moderate.

What "special controls" means: Special controls are measures beyond general controls that the FDA has determined are necessary to provide reasonable assurance of safety and effectiveness for a given device type. Special controls can include: performance standards, post-market surveillance requirements, patient registries, guidance documents, premarket data requirements, and other measures established by the FDA through regulation or guidance. Special controls are device-type specific: the special controls for a glucose monitor differ from those for an infusion pump.

Premarket submission: The majority of Class II devices require a 510(k) premarket notification before marketing. Clearance demonstrates that the device is substantially equivalent to a legally marketed predicate and meets applicable special controls. Some Class II devices are exempt from 510(k) by regulation; these are noted in the relevant Parts 862 through 892 classification entry.

Examples: Powered wheelchairs, infusion pumps, diagnostic imaging equipment, glucose monitors, certain robotically-assisted surgical devices, many software as a medical device (SaMD) products, daily-wear soft contact lenses.

Marketing implication: A 510(k)-cleared Class II device is "FDA cleared." The clearance letter specifies the device's cleared intended use and indications for use, which define the boundaries of your marketing claims. Claims that exceed the cleared indications can establish a new intended use, which the FDA has traditionally treated as misbranding or as requiring a new 510(k). See our article on how the 510(k) submission process works for the complete clearance process.

Class III: Premarket Approval

Risk level: Highest.

What PMA requires: For Class III devices, general controls and special controls are deemed insufficient to assure safety and effectiveness. PMA is required: the FDA independently evaluates valid scientific evidence demonstrating reasonable assurance that the device is safe and effective for its intended use. This almost always requires clinical data from controlled investigations.

Examples: Implantable cardiac pacemakers, cochlear implants, mechanical heart valves, deep brain stimulators, certain implantable infusion pumps, silicone gel-filled and saline-filled breast implants.

Premarket submission: Premarket Approval application (PMA), under 21 CFR Part 814 (https://www.law.cornell.edu/cfr/text/21/part-814) and the authority of FD&C Act Section 515 (21 U.S.C. 360e, https://www.law.cornell.edu/uscode/text/21/360e). The FDA's PMA program page is at https://www.fda.gov/medical-devices/premarket-submissions-selecting-and-preparing-correct-submission/premarket-approval-pma.

Marketing implication: A PMA-approved device is "FDA approved." This is the only class of device for which the "approved" designation is accurate. See our comparative article on PMA vs 510(k) vs De Novo pathways for how PMA approval affects your marketing program and what you can and cannot claim.

How Classification Is Determined

Classification is not self-assigned. The FDA assigns device classifications through one of two mechanisms.

Regulation. Most device types have a classification regulation in 21 CFR Parts 862 through 892. These regulations were developed by FDA advisory panels and codified through notice-and-comment rulemaking. A company can look up its device type in the applicable CFR part or in the FDA's product classification database to find the assigned class, product code, and any premarket requirements.

Petition or reclassification. If no classification regulation covers a device type (because the device is novel), the device is automatically designated Class III under Section 513(f) of the FD&C Act until classified otherwise. The company can pursue De Novo classification under Section 513(f)(2) to seek Class I or Class II designation, or can petition for reclassification under Section 513(e) to down-classify a device type from Class III to Class I or II based on new evidence.

The product classification database at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfPCD/classification.cfm is searchable by device name, product code, panel, and 21 CFR part. It returns the device class, the applicable CFR section, and whether a 510(k) is required.

The Practical Lookup Process

Finding your device's classification takes three steps.

Step 1: Search the FDA product classification database. Enter a keyword describing your device (for example, "glucose monitor," "infusion pump software," "surgical stapler"). The database returns matching device types with product codes, classifications, and CFR citations.

Step 2: Read the applicable CFR section. The CFR section for your device type will state the class and any special controls, performance standards, or exemptions. If the section says "510(k) exempt," no premarket submission is required. If it says "class II" without an exemption, a 510(k) is required. If it says "class III," a PMA is required.

Step 3: Confirm with regulatory counsel. The product classification database and CFR are the starting point, not the final word. Novel devices, combination products, software as a medical device, and devices with evolving special controls often require a classification analysis that goes beyond a database lookup. Classification also interacts with intended use: the same technology classified as Class I for one intended use may be Class II or III for a different intended use.

Classification, Marketing, and the Product Code

One detail that matters for marketing operations: the product code. Each device type in the classification database is assigned a three-letter product code (for example, FRN for certain glucose monitors, KZH for certain diagnostic ultrasound systems). The product code appears in 510(k) clearance letters and in the FDA's databases. When your marketing team references FDA clearance, having the K-number and product code on file allows you to point distributors, hospital procurement teams, or investor relations staff directly to the FDA's public record of the clearance.

The 510(k) database (https://www.fda.gov/medical-devices/510k-clearances/search-510k) is searchable by K-number, device name, applicant, and product code. Knowing your product code makes it easier to monitor competitive clearances and changes in the predicate landscape.

Where Classification Fits in Your Launch Plan

For marketing leaders, classification is an input, not a deliverable. But getting it right early prevents timeline surprises and copy rewrites.

If your device is Class I exempt, you can begin marketing as soon as it meets general controls. The regulatory milestone is facility registration and device listing, not clearance.

If your device is Class II requiring 510(k), your marketing launch is gated by clearance. Build your launch content against draft indications for use, build a regulatory claims review step into your content workflow, and plan for the MDUFA V review window plus Additional Information cycles between submission and clearance.

If your device is Class III requiring PMA, your timeline and marketing strategy look fundamentally different. Plan in years, not months. Build your pre-approval marketing around clinical data communication, investor relations, and key opinion leader development.
