510(k)-Exempt in 2026: How to Check the QMSR, Registration, and UDI Duties You Owe

"510(k)-exempt" is one of the most misunderstood phrases in medical device regulation. Read literally, it sounds like a device that is exempt from regulation. It is not. The exemption removes one filing — the premarket notification — and leaves almost everything else intact. A 510(k)-exempt device is still a regulated device, made in a registered establishment, labeled with a UDI, governed by a quality system, and subject to adverse-event reporting. Treating "exempt" as "free to ship with no program" is the kind of mistake that produces warning letters.

This article is a practical 2026 checklist for what survives a 510(k) exemption. It covers how to confirm a product code is actually exempt, which duties remain (and how the QMSR transition that took effect February 2, 2026 reshapes the quality-system duty), and the conditions that quietly strip an exemption away. For the specific lists of codes FDA has newly exempted in 2026, see our Class II 510(k) exemption proposals guide and our June 2026 unclassified-device exemption update. This article is the cross-cutting companion: regardless of which exemption applies, here is what you still owe.

Step 1: Confirm the Exemption in the Classification Database

The first step is not to assume — it is to look up the product code. FDA's Product Classification database publishes a submission-type field for each of the roughly 7,000 device product codes, indicating whether a code goes through 510(k), PMA, or is exempt. Two companion lists codify exemptions: the Class I and Class II device exemption lists, and the per-regulation limitation language in 21 CFR 862.9 through 892.9.

To see how large the exempt population is, we analyzed the complete FDA device classification dataset. Across 7,068 product codes:

| Submission type (FDA classification) | Product codes | Typical class | |---|---| | 510(k) (premarket notification) | 3,204 | Mostly Class II | | 510(k)-exempt | 2,637 | Mostly Class I (2,153) + some Class II (484) | | PMA (Class III) | 500 | Class III | | Unclassified / other | ~727 | Unclassified or special categories |

So roughly 2,637 product codes — about 37% of all classified device codes — carry 510(k)-exempt status, and they are overwhelmingly low-risk Class I devices (manual surgical instruments, examination gloves, tongue depressors, simple reagents) plus a minority of well-understood Class II types. Confirming your specific code sits in that exempt column is the prerequisite to everything below.

Step 2: Understand That "Exempt" Means "Exempt From 510(k)" — Not Exempt From General Controls

The FDA Class I and Class II exemptions page is explicit: a 510(k)-exempt Class I or Class II device "must still comply with other requirements (known as regulatory controls) unless the device is expressly exempt from those requirements." In other words, exemption from one general control does not extend to the others.

The general controls that survive a 510(k) exemption are:

• Establishment registration and device listing (21 CFR Part 807)
• Quality system requirements (21 CFR Part 820, now the QMSR) — unless expressly GMP-exempt
• Medical Device Reporting (21 CFR Part 803)
• Corrections and removals (21 CFR Part 806)
• Labeling (21 CFR Parts 801 and 812 as applicable)
• UDI labeling (21 CFR Part 830 and 21 CFR 801 Subpart B)
• Records and complaint files (21 CFR 820.180 and 820.198)

A 510(k) exemption relieves you of preparing a premarket notification and proving substantial equivalence to a predicate. It does not relieve you of being a registered, quality-governed, traceable, reportable manufacturer.

Step 3: The Quality-System Duty and the QMSR Transition

This is the duty most often underestimated. Since February 2, 2026, the FDA's quality-system regulation has been the Quality Management System Regulation (QMSR), which amends 21 CFR Part 820 by incorporating ISO 13485:2016 by reference. The old Quality System Regulation (QSR) text has been removed and replaced with references to ISO 13485, harmonizing FDA's current good manufacturing practice (CGMP) requirements with the international standard.

What this means for a 510(k)-exempt manufacturer in 2026 is best understood as two tiers of exemption:

• Tier 1 — 510(k)-exempt, but NOT GMP-exempt (the majority of exempt devices). Unless a device's classification regulation expressly exempts it from GMP requirements, the manufacturer must establish and maintain a quality system conforming to ISO 13485:2016. FDA has stated the QMSR applies to the same entities that were subject to the QSR — primarily finished-device manufacturers. Most Class I and essentially all exempt Class II devices fall here: no 510(k), but a full quality system is still required.
• Tier 2 — 510(k)-exempt AND GMP-exempt (a narrow subset of Class I devices). A smaller group of low-risk Class I devices is exempt from both 510(k) and GMP. Even here the exemption is partial: the manufacturer must still comply with the recordkeeping requirements of 21 CFR 820.180 and the complaint-file requirements of 21 CFR 820.198. These devices also generally do not require formal Design Controls (21 CFR 820.30), but a Device Master Record (DMR) is still expected.

Two conditions move a device out of Tier 2 and into full quality-system scope regardless of class: if the device is labeled or represented as sterile, or if the device contains software, it is not GMP-exempt and the full QMSR applies. This is the trap that catches teams who assumed a Class I exemption carried through to quality-system obligations.

To see which tier a specific product code sits in, check the FDA's Medical Device Exemptions: 510(k) and GMP Requirements list, which annotates the small subset of codes that are also GMP-exempt.

Step 4: Registration, Listing, UDI, and Reporting Duties That Always Survive

These four duties apply to essentially every device in commercial distribution in the United States, exempt or not:

1. Establishment registration and device listing. Every manufacturer (and contract manufacturer, specification developer, repackager/relabeler, contract sterilizer, remanufacturer, reprocessor, and initial importer) must register its establishment and list its devices under 21 CFR Part 807. Foreign establishments must also designate a US agent. The annual establishment registration fee for FY 2026 is $11,423. See our FDA Establishment Registration & Device Listing guide for the full registration workflow.

2. UDI labeling and GUDID submission. Unless expressly exempt, devices must bear a Unique Device Identifier and the labeler must submit device identifier records to the FDA's GUDID database under 21 CFR Part 830. The UDI rule applies broadly, and exempt status does not generally relieve UDI duties. See our UDI verification lookup workflow for how a UDI is structured and looked up.

3. Medical Device Reporting (MDR). Manufacturers and initial importers must report device-related deaths, serious injuries, and certain malfunctions to FDA under 21 CFR Part 803. Exemption from 510(k) does not narrow MDR obligations.

4. Corrections and removals. Under 21 CFR Part 806, manufacturers and importers must report certain corrections and removals and maintain records of others. This duty is independent of premarket pathway.

Step 5: Watch the Exemption Limitations — When an Exemption Lapses

A 510(k) exemption is conditional. The general limitations set out in 21 CFR 862.9 through 892.9 mean a manufacturer must still submit a 510(k) before introducing the device into commercial distribution when the device meets certain conditions, including:

• A new intended use compared to the generic type
• Use of different fundamental scientific technology than the classified type
• The device is sterile and the generic type was not, or contains software
• The device has potential for an unreasonable risk of illness or injury
• Any change likely to significantly affect safety or effectiveness

The practical test: the exemption covers the well-understood, low-risk version of the device type described in the classification regulation. The moment you push beyond that — a new indication, a new sterilization state, embedded software, a new energy source — the exemption likely no longer applies, and a 510(k), De Novo, or PMA may be required. If you are unsure whether your specific change falls outside the exemption, the conservative path is to classify the device as though the exemption does not apply, or to request confirmation from FDA.

The 2026 Exempt-Device Compliance Checklist

Before marketing a 510(k)-exempt device in 2026, confirm each item:

• Product code confirmed exempt in the FDA Product Classification database (submission type = exempt)
• Regulation reviewed for exemption limits (21 CFR 862.9–892.9), and the device's features (sterile? software? new intended use?) checked against those limits
• Establishment registered and devices listed under 21 CFR Part 807; foreign establishments have a designated US agent
• QMSR (ISO 13485:2016) quality system established and maintained — or, for the narrow GMP-exempt Class I subset, recordkeeping (820.180) and complaint files (820.198) in place
• UDI labeling applied and GUDID DI records submitted under 21 CFR Part 830
• MDR procedures (21 CFR 803) and corrections-and-removals procedures (21 CFR 806) implemented
• Labeling compliant with 21 CFR Part 801
• Documented rationale on file for why the exemption applies to this specific device configuration — useful in an inspection and when the design changes

Bottom Line

Across roughly 2,600 of the 7,068 product codes in the FDA classification database, 510(k) is not required. But "no 510(k)" is not "no compliance." In 2026, an exempt device is still made under the QMSR (the ISO 13485:2016-based regulation effective February 2, 2026), in a registered and listed establishment, with UDI labeling and GUDID records, under MDR and corrections-and-removals duties — unless each of those is expressly exempted in the device's own classification regulation. Confirm the exemption in the classification database, map the surviving duties, and watch the conditions that quietly remove the exemption. That is the difference between a compliant exempt launch and a misbranded device.
