Is a Screen Print “Paint”? The Unresolved CPSIA Question

Two federal rules point in opposite directions on whether a cured screen print is "paint," and we could not find a single CPSC document that resolves it. This is the most consequential open question in decorated children's apparel, and most of what is published about it is written with a confidence nobody has earned.

Here is both sides of it, honestly, and the practical position we take. General information about federal regulation, not legal advice.

Why it matters

Two different lead limits apply to children's products, and which one governs a print depends on this question.

• Total lead content — 100 parts per million in accessible component parts, under 15 U.S.C. 1278a.
• Lead in paint and similar surface coatings — 0.009 percent by weight of the nonvolatile content or of the dried paint film, which is 90 parts per million, under 16 CFR 1303.1(a).

The numbers are close, so the limit itself is not really the issue. Three other consequences are:

1. What the certificate cites. If part 1303 applies, it belongs on the Children's Product Certificate as a separate rule.
2. How the test is run. Surface coating testing separates and digests the coating apart from the substrate, which is a different test than a bulk content test on a garment component.
3. Small batch relief. Part 1303 is one of the rules small batch manufacturers can never be relieved from. A shop planning to lean on small batch registration needs to know whether its print falls under it.

The case that a print is not paint

The definition at 16 CFR 1303.2(b) describes paint and similar surface-coating materials as a fluid, semi-fluid or other material, with or without a suspension of finely divided coloring matter, which changes to a solid film when a thin layer is applied to a metal, wood, stone, paper, leather, cloth, plastic or other surface. Then it adds the exclusion:

The term "does not include printing inks or those materials which actually become a part of the substrate," such as the pigment in a plastic article, or materials actually bonded to the substrate, such as by electroplating or ceramic glazing.

On its face that is a clean answer. Screen printing ink is a printing ink. Printing inks are excluded. Done.

The case that it is

Two things cut hard the other way.

The lead determination assumes some inks are covered by 1303

16 CFR 1500.91(d)(6) determines that CMYK process printing inks do not exceed the lead content limit — then excludes from that determination spot colors, other inks not used in CMYK process, "inks that do not become part of the substrate under 16 CFR part 1303," and inks used in after-treatment applications including screen prints, transfers, decals or other prints.

That middle phrase only makes sense if CPSC contemplates that some printing inks are governed by part 1303. If the 1303.2(b) exclusion swept in every printing ink categorically, the carve-out would have nothing to describe.

And plastisol is the obvious candidate. It is a plasticized PVC that cures into a discrete film sitting on top of the fabric. It does not become part of the fiber the way a dye does — a plastisol print can be scraped, cracked and peeled off a shirt, which is the entire subject of a different article we wrote. A material that can flake off the substrate is difficult to describe as having become part of it.

CPSC's own example certifies to 1303

CPSC publishes a sample Children's Product Certificate for clothing. The product is a baby bodysuit with a screen printed decoration. The rules listed on that certificate include 16 CFR part 1303, paints and similar surface coatings.

That is the agency's own worked example of a screen printed children's garment, and it treats the print as reaching part 1303. It is not a rulemaking and it is not binding. It is also the single clearest signal available about how the agency thinks about the question.

What we could not find

We looked for a CPSC guidance document, staff opinion, rulemaking preamble or enforcement action squarely holding that cured plastisol on a garment is, or is not, paint under part 1303.

There isn't one that we could locate. A CPSC staff document on lead paint testing obtained through a public records request addresses only the mechanics — that a coating must be removed and digested separately from the substrate material — and says nothing about textile prints.

So anyone telling you the answer with confidence is either citing something we did not find, in which case we would genuinely like to see it, or they are telling you what is convenient.

The position we take, and why

Treat cured plastisol and similar films as a surface coating subject to the 90 ppm lead-in-paint limit.

The reasoning is asymmetric risk, not legal certainty. Work through both errors:

• If you treat it as a coating and you were wrong, you paid for a line on a test report and listed one extra rule on a certificate. Cost: negligible.
• If you treat it as exempt and you were wrong, you have an uncertified children's product, certified to the wrong rules, and you cannot fall back on small batch relief because part 1303 is one of the rules it never covers. Cost: a recall on a school order.

When the agency's own example goes one way and the downside is lopsided, the choice is not difficult.

There is also a piece of good news buried in 16 CFR 1109.11. For coatings, the substrate the laboratory tests need not be the same material as the finished product, and the coating may be submitted in liquid form or as a dried film. Which is exactly how ink manufacturers test. So taking the conservative position does not mean sending shirts to a laboratory — it means asking your ink supplier for the report they already have. See component-part testing.

Separately: the print is outside the lead determination either way

Whatever the answer on paint, the total-lead-content analysis is already settled and it is not in the decorator's favor.

The textile determination at 16 CFR 1500.91(d)(7) relieves dyed natural and manufactured fibers from lead testing, but excludes textiles containing treatments or applications that do not consist entirely of dyes. And (d)(6) expressly excludes inks used in after-treatment applications, including screen prints, transfers, decals, or other prints.

The rulemaking record explains it. Screen printing spans UV, water-based, plastisol and solvent systems, and the Commission stated it could not determine that all screen printing inks are free of lead. Spot colors were excluded because they could contain leaded pigments, verifiable only by testing. Dyes dissolve and bond into the fiber; pigments are insoluble and sit in a binder on the surface.

So the blank is relieved of lead testing and the print is not, regardless of how the paint question comes out. That is the part shops most often have backwards.

DTF: even less settled

Direct-to-film postdates the 2009 determinations entirely, and we found no CPSC, trade association or laboratory guidance addressing it under CPSIA at all.

On the text of the rules, a DTF transfer is plainly an after-treatment application and therefore outside the printing-ink determination, and the cured pigment-and-adhesive film sits on the fabric surface much as plastisol does, so the part 1303 analysis above applies with at least equal force. There is an additional component nobody discusses: the hot-melt adhesive powder, typically a thermoplastic polyurethane, is a distinct component part with no determination covering it. A shop relying on component-part testing needs documentation for the powder as well as the ink.

That is reasoning from rule text, not a published position, and we are labeling it as such. We do not apply DTF to infant and toddler items for exactly this reason.

Questions

Is screen print ink considered paint under CPSIA?

It is unresolved. 16 CFR 1303.2(b) excludes printing inks and materials that become part of the substrate from the definition of paint and similar surface coatings. But 16 CFR 1500.91(d)(6) carves out "inks that do not become part of the substrate under 16 CFR part 1303," which implies some printing inks are covered, and CPSC's own sample Children's Product Certificate for a screen printed baby bodysuit lists part 1303 as an applicable rule. We found no CPSC document squarely resolving it.

What is the lead limit for a print on a kids' shirt?

Total lead content in accessible component parts is limited to 100 ppm under 15 U.S.C. 1278a. Lead in paint and similar surface coatings is limited to 0.009 percent by weight of the nonvolatile content or the dried film — 90 ppm — under 16 CFR 1303.1(a). Which of the two governs a cured print is the open question; the conservative practice is to satisfy both.

Is the printed area covered by the textile lead exemption?

No. 16 CFR 1500.91(d)(7) relieves dyed natural and manufactured fibers from lead content testing but excludes textiles containing treatments or applications that do not consist entirely of dyes, and 1500.91(d)(6) expressly excludes inks used in after-treatment applications including screen prints, transfers, decals and other prints. The blank is relieved of testing; the print is not.

Does small batch registration cover the lead-in-paint rule?

No. 16 CFR part 1303 is one of the rules that small batch manufacturers must always third-party test for, along with small parts, pacifiers, durable infant and toddler products, lead in children's metal jewelry, and baby bouncers, walkers and jumpers. If a print falls under part 1303, small batch relief does not excuse testing it.

Do I have to send shirts to a lab to test the ink?

Generally no. 16 CFR 1109.11 provides that for a coating, the substrate the laboratory tests need not be the same material as the finished product, and the coating may be submitted in liquid form or as a dried film. Ink manufacturers test this way, so the practical step is obtaining the ink maker's third-party report for the specific line and colors you print.
