A personal flotation device is legal on a U.S. vessel only if it carries a Coast Guard approval label and is in serviceable condition when you are underway. Coast Guard PFD approval and labeling standards, rewritten under a harmonization final rule that took effect in January 2025, replaced the old Type I through V categories with performance levels numbered 50 to 275, and the label on every approved device is what tells you (and an inspector) which standard it was approved under and how it may be used.1Federal Register. Lifejacket Approval Harmonization
What the Approval Label Must Show
The permanent label sewn or printed onto a Coast Guard-approved PFD is both a compliance marker and a user guide. Federal regulations require it to carry the Coast Guard approval number, the manufacturer’s contact information, the model name or number, a lot number and manufacture date, sizing information, and any limitations or special instructions for use.2eCFR. 46 CFR Part 160 Subpart 160.076 – Inflatable Recreational Personal Flotation Devices The approval number points back to a specific subpart of 46 CFR Part 160, which is how an enforcement officer confirms which standard the device was tested against.
Under the harmonized system, labels also carry universal warning icons showing the device’s limitations at a glance — whether it is suitable for high-speed activity, personal watercraft use, or specific conditions. If the device is designated “wear-only,” the label says so, and that phrase changes how the PFD counts toward your legal carriage. A stowed wear-only PFD is treated as if it were not aboard.
If the label becomes illegible, detached, or unreadable, the whole device can be declared unserviceable. That matters because operating a vessel without a serviceable PFD where one is required exposes you to a federal civil penalty of up to $1,000 per violation, and the vessel itself can be held liable.3Office of the Law Revision Counsel. 46 USC 4311 – Penalties and Injunctions
Performance Levels 50 Through 275
The number on a harmonized label is the minimum buoyancy in Newtons. Higher numbers mean more flotation and better protection farther from help. The Coast Guard adopted these levels alongside Transport Canada and industry standards bodies so boaters crossing between U.S. and Canadian waters do not have to read two incompatible labeling systems.1Federal Register. Lifejacket Approval Harmonization
- Level 50 — about 11 pounds of buoyancy, for strong swimmers close to shore with help nearby. No turning capability; it will not rotate an unconscious wearer face-up.
- Level 70 — roughly 15.7 pounds of buoyancy, the workhorse category for calm inland waters and general recreational use. Not required to turn an unconscious person face-up.
- Level 100 — for sheltered waters where rescue may not arrive immediately. Limited ability to rotate an unconscious wearer.
- Level 150 — about 33.7 pounds of buoyancy, for offshore or foul-weather use. Will turn most unconscious wearers into a safe breathing position without any action on the wearer’s part.
- Level 275 — the heaviest-duty category, intended for extreme offshore conditions, heavy clothing, or long rescue times.
The single most important dividing line is turning ability. Someone incapacitated and floating face-down drowns quickly, so matching the level to the actual boating environment matters more than picking the most comfortable vest on the shelf.
Old Type I Through V Labels Are Still Legal
Before the harmonization rule, every Coast Guard-approved PFD fell into one of five Type categories. Devices approved under that system remain legal as long as they are in serviceable condition and used according to their labels.1Federal Register. Lifejacket Approval Harmonization Rough correspondence to the new levels:
- Former Type I (offshore) — closest to Level 150 or 275.
- Former Type II (near-shore) — closest to Level 100.
- Former Type III (flotation aid) — closest to Level 70.
- Former Type IV (throwable) — no direct performance-level equivalent; throwables remain a separate category under approval series 160.064 and 160.049.4United States Coast Guard. Personal Floatation Devices
- Former Type V (special use) — activity-specific devices that do not map cleanly to a single level.
The mapping is approximate because the old rules were written around design specifications and the new ones around measured performance. A device that met Type III design rules could test differently under the harmonized criteria, which is why new approvals are tested against ANSI/CAN/UL standards rather than the legacy design requirements.1Federal Register.

When the Device Counts: Wear-Only and Inflatable Rules
The label controls not just what the device is, but when it counts toward your one-per-person requirement. Most Coast Guard-approved inflatable PFDs count only when actually worn. An inflatable tossed in a storage compartment does not satisfy federal carriage rules, and the label will state this restriction directly.5eCFR. 46 CFR Part 160 Subpart 160.276 – Wearable Recreational Inflatable Personal Flotation Devices
Approved inflatables are also authorized only for wearers at least 16 years old on recreational vessels. An inflatable designed for someone under 16 must automatically inflate, must not require the wearer to put it on after inflation, must be worn at all times, and must carry a warning about adult supervision.
Inflatables carry a maintenance burden that foam vests do not. The CO2 cylinder has to be full and properly installed, the status indicator (usually a small window showing green) has to confirm the mechanism is armed, the bladder has to hold air, and the oral inflation tube has to be clear and intact. A device that fails any of these checks is legally unserviceable.6eCFR. 33 CFR 175.23 – Serviceable Condition Some manufacturers call for replacing automatic inflation bobbins every three to four years and certain inflator units every five, so the owner’s manual referenced on the label is worth keeping.
Serviceable Condition
An approved label does not carry a PFD through its whole life. The device has to remain in serviceable condition every time the vessel leaves the dock, and federal regulations spell out what serviceable means. An inspector can declare a PFD unserviceable on the spot for any of the following:6eCFR. 33 CFR 175.23 – Serviceable Condition
- Broken or corroded metal or plastic hardware — buckles, snaps, clasps.
- Ripped, torn, or detached straps and webbing.
- Rotted or deteriorated structural components that fail under a tug.
- Buoyant material that is hardened, permanently compressed, waterlogged, oil-soaked, or mildewed, or rips and open seams large enough for the material to escape.
- Missing foam or foam that has shifted out of its intended position.
Foam failure is the sneakiest problem. A vest can look fine outside while the foam inside has shrunk, gone brittle, or lost its spring. The Coast Guard suggests a squeeze test: compress the foam to about half its thickness and let go. If it does not bounce back within a few seconds, replace the device. Wrinkling on a vinyl-dipped jacket or a loose-fitting fabric shell can both point to internal foam shrinkage.
Carriage Rules and State Law
Federal law requires at least one wearable, Coast Guard-approved PFD of the proper size for every person aboard a recreational vessel, used according to the conditions on its approval label. Vessels 16 feet or longer must also carry one throwable device. Children under 13 must wear an approved PFD at all times while the vessel is underway unless they are below decks or inside an enclosed cabin.7eCFR. 33 CFR 175.15 – Personal Flotation Devices Required Canoes and kayaks 16 feet or longer are exempt from the throwable requirement; racing shells, rowing sculls, racing canoes, racing kayaks, and sailboards are fully exempt from PFD carriage.8eCFR. 33 CFR 175.17 – Exemptions
Many states set stricter age thresholds or additional requirements, so approval and labeling compliance under federal law is the floor, not the ceiling — check your state’s boating laws before you launch.
