If you sell a toy, game, or kids’ product with small pieces, you’ve probably seen the yellow-bordered “WARNING: CHOKING HAZARD” label on competitors’ packaging and wondered whether you need one too. Getting this wrong in either direction is a problem: skip a required label and you risk a Consumer Product Safety Commission (CPSC) enforcement action or a retailer rejecting your shipment; add one where it isn’t needed and you’re cluttering your packaging and possibly signaling the wrong age range to shoppers.
This guide walks through exactly when the choking hazard label is legally required under CPSC regulations, what the label has to say word-for-word, where it has to physically go on your packaging, and the mistakes that trip up small brands most often.
Quick Answer
A choking hazard warning label is required when a toy or game is intended for children at least 3 but under 6 years old and contains a “small part” as defined under 16 CFR 1500.19. Small balls, marbles, and latex balloons carry their own labeling requirements with a different cutoff — up to under 8 years old — because CPSC treats those three categories as higher risk even for slightly older kids. Products intended for children under 3 can’t contain small parts at all — no label can make that legal, the part has to come out or the product has to be redesigned.
How to Determine If Your Product Needs a Label
Start with intended age, not actual age. CPSC looks at how you market and package the product — box copy, imagery, complexity, retail placement — to decide the intended age range, regardless of what age number you print on the box. If your overall marketing impression reads as appealing to a 2-year-old, a “For ages 4+” label won’t save you if it also contains small parts.
Next, check whether any component is a “small part.” CPSC uses a physical test: a small parts cylinder measuring 2.25 inches long by 1.25 inches wide, defined in 16 CFR 1501.4, which approximates a young child’s fully expanded throat. Any piece that fits entirely inside that cylinder, in any orientation, without being compressed, counts as a small part — including pieces that break off during normal use-and-abuse testing, not just parts that are loose as originally packaged. If your toy or game is intended for a child at least 3 but under 6 and contains a piece like this, it needs the general small-parts warning.
Small balls, marbles, and latex balloons are a separate track with their own rules. Because CPSC considers these three categories a distinct choking and aspiration risk, the requirement to carry a warning reaches further up the age range — a toy or game containing a small ball or marble needs a warning if it’s intended for children at least 3 but under 8, rather than the under-6 range used for the general small-parts warning. That means a toy graded for, say, 6- or 7-year-olds can be free of the general small-parts label and still need a warning if it includes a marble or a small ball. Latex balloons need a warning regardless of the intended age of the toy or game they come with.
Finally, check the exemption list before you assume a label is required. CPSIA and its implementing regulations exempt certain product categories from the small parts ban and labeling rule, including books and other paper products, writing instruments like pencils and crayons, children’s clothing and its buttons, feeding utensils, grooming items like toothbrushes, pacifiers, rattles, and modeling clay or paint sets covered by other standards. If your product falls in one of these categories, the small-parts labeling rule generally doesn’t apply, though other safety rules still might.
The Exact Label Wording and Placement Rules
CPSC regulations specify the label text closely enough that you shouldn’t paraphrase it. For a toy or game with small parts intended for children at least 3 but under 6, the required text is: “WARNING: CHOKING HAZARD — Small parts. Not for children under 3 yrs.” Toys and games containing a small ball or a marble use very similar wording keyed to “under 3 yrs” as well — the higher age figure (under 8) describes which products are required to carry the warning, not a number that shows up in the small-ball or marble label text itself. Latex balloons are the exception: their required wording explicitly states that children under 8 can choke or suffocate on uninflated or broken balloons, along with instructions to keep uninflated balloons away from children and discard broken ones immediately.
Placement matters as much as wording. The warning must appear on the product’s principal display panel — the panel a shopper sees first on the shelf — with the warning text blocked together in its own square or rectangular area, set out across at least two lines. If your packaging’s principal display panel is small (roughly 15 square inches or less), an abbreviated warning can appear there instead, as long as it points shoppers to the full warning elsewhere on the package with an arrow or similar reference. Loose or unpackaged items sold from a bin need the warning on the bin or the retail display itself.
The rule follows the product online, too. If you sell on a marketplace or your own site, the full, unabbreviated warning text must appear at the start of the product-specific description wherever a shopper can complete a purchase directly — the small-package abbreviation exception does not apply to internet listings.
Tips / Common Mistakes
The most common mistake is treating the age number on the box as the whole compliance story. CPSC evaluates the total marketing impression — a “6+” collectible marketed with cartoon characters and sold in the toy aisle next to preschool items can still get flagged as intended for a younger child. Match your marketing to your actual target age, not just the label.
Second, don’t confuse the two age ranges. The general small-parts warning applies to toys and games intended for children at least 3 but under 6; the requirement to warn about small balls and marbles reaches up to under 8. Assuming every small-parts product follows the same age range as balls and marbles — or vice versa — is a frequent labeling error.
Third, remember that small parts include pieces that break off during testing, not just pieces that ship loose. A plush toy with an eye that’s securely stitched on today but pulls free under CPSC’s use-and-abuse protocol still fails the test — design and testing need to account for that, not just the as-sold state.
Finally, watch multi-item kits and subscription boxes. If a kit bundles several small toys or components aimed at children under 6, or includes balls, marbles, or balloons aimed at children under 8, each qualifying item — or the kit packaging as a whole — needs the appropriate warning, and it’s easy to miss when items are sourced from different suppliers with inconsistent labeling.

CPSC Small Parts Choking Hazard Warning Label FAQs
Does this rule apply to small or handmade toy businesses, or just large manufacturers?
It applies regardless of company size. CPSIA labeling and small-parts obligations fall on any manufacturer, importer, or private labeler selling a covered product in the U.S., including small businesses, Etsy sellers, and craft makers.
What exactly is the small parts test cylinder?
It’s a physical test tube specified in 16 CFR 1501.4 measuring 2.25 inches long by 1.25 inches wide, designed to approximate the fully expanded throat of a child under 3. Any component that fits entirely inside it, uncompressed and in any orientation, is legally a small part.
If I add a choking hazard warning label, does that protect me if a young child chokes on my product?
No. The warning label only applies to products correctly age-graded for children old enough to legally contain small parts. If a product is genuinely intended for children under 3, small parts are prohibited outright — a warning label doesn’t make an under-3 product with small parts legal or safe, and won’t shield you from liability.
Why do balloons, small balls, and marbles have a broader age range for warnings than other small parts?
CPSC treats these three categories as posing a distinct choking and aspiration risk even to somewhat older children, so the requirement to carry a warning reaches up to children under 8, rather than the under-6 range used for the general small-parts warning.
