When a product is labeled TSCA Title VI compliant, it means the composite wood inside it meets the EPA’s federal formaldehyde emission limits under Title VI of the Toxic Substances Control Act, codified at 40 CFR Part 770. Those limits cap how much formaldehyde plywood, particleboard, and fiberboard can release into indoor air, and they apply to every covered panel, component, and finished good sold or manufactured in the United States, whether made here or imported.
The label is a promise about two things: the product’s emissions are at or below a specific ceiling, and an independent third-party certifier has verified that fact. It is not something a manufacturer can stamp on a box on its own say-so.
Why the Standard Exists
Formaldehyde is a chemical commonly used in the adhesives that bind composite wood. At low concentrations it can irritate the eyes, nose, throat, and skin. Higher levels can cause rashes, shortness of breath, and wheezing, with young children, the elderly, and people with asthma more sensitive to those effects. Long-term exposure to very high concentrations has been linked to rare nose and throat cancers in workers with occupational exposure.1ATSDR – CDC Archive. Formaldehyde and Your Health
Composite wood sits inside cabinets, flooring, shelving, and furniture across most American homes, which makes it one of the most common indoor sources of formaldehyde off-gassing. The Title VI rules are designed to keep that off-gassing below the levels tied to health complaints.
Which Products the Label Applies To
Three panel categories are covered: hardwood plywood with a veneer or composite core, medium-density fiberboard (MDF), and particleboard.2eCFR. 40 CFR Part 770 — Formaldehyde Standards for Composite Wood Products Any finished good containing one of those materials is also covered, including kitchen cabinets, bookshelves, laminate flooring, desks, and similar items. Laminated products, where a wood veneer is bonded to a particleboard, MDF, or veneer-core platform, fall under the same rules, and composite wood built into manufactured homes is covered too.
Several categories are outside the standard, and it helps to know them before assuming a label is missing where it should be:
- Structural products: structural plywood, structural panels, oriented strand board, structural composite lumber, glued laminated lumber, prefabricated wood I-joists, and finger-jointed lumber.
- Hardboard, which is manufactured differently from MDF.
- Wood packaging like pallets, crates, spools, and dunnage.
- Secondhand goods, meaning any finished item previously sold to an end user who bought it in good faith for personal use, including antiques and used furniture.
A few narrower carve-outs also apply. Windows with less than five percent composite wood by volume are exempt. Exterior doors and garage doors are exempt if they use no-added-formaldehyde or ultra-low-emitting resins, or contain less than three percent composite wood by volume.3eCFR. 40 CFR 770.1 — Scope and Applicability
The Emission Limits Behind the Label
Each product type has its own ceiling, measured in parts per million using the large-chamber test method ASTM E1333:
- Hardwood plywood (veneer or composite core): 0.05 ppm
- Particleboard: 0.09 ppm
- Medium-density fiberboard: 0.11 ppm
- Thin medium-density fiberboard: 0.13 ppm
A smaller-chamber method, ASTM D6007, is also allowed if the testing lab demonstrates equivalence to the large-chamber results at least once per year.4eCFR. 40 CFR 770.20 — Testing Requirements
How This Relates to CARB Phase 2
If you also see a product marked “CARB Phase 2 compliant,” the emission limits are the same numbers. The EPA modeled its standards on the California Air Resources Board’s earlier Phase 2 rule, so a product meeting one meets the other. There’s no need to source separate CARB and TSCA materials for California versus the rest of the country.5eCFR. 40 CFR 770.10 — Formaldehyde Emission Standards
How Compliance Is Verified
Manufacturers do not certify themselves. The label rests on EPA-recognized Third-Party Certifiers (TPCs) that independently verify each panel producer’s emissions. A TPC must be accredited to ISO/IEC 17065 by an EPA-recognized Accreditation Body and must either operate or contract with a lab accredited to ISO/IEC 17025 for formaldehyde testing.6eCFR. 40 CFR 770.7 — Third-Party Certification
For every producer it certifies, a TPC handles quarterly emission testing performed by an accredited lab, regular facility inspections to check the producer’s quality assurance and quality control procedures, and review of the producer’s own internal test data between quarterly tests. The EPA publishes the current list of recognized TPCs on its website.
What the Label Should Show
Labeling is how the compliance claim travels through the supply chain, and it looks different at different points.
Composite wood panels, or bundles of panels, must carry a label showing the panel producer’s name, the production lot number, the TPC’s EPA number, and a statement that the products are TSCA Title VI certified.7eCFR. 40 CFR 770.45 — Labeling If individual panels are not each labeled, the seller has to use a tracking method such as color-coded edge marking that ties every panel back to its label information, and must share that information with customers on request.
Finished goods with composite wood inside must be labeled with the fabricator’s name, the production date in month/year format, and a statement that the goods are TSCA Title VI compliant.7eCFR. 40 CFR 770.45 — Labeling Where individual items are not labeled, the retailer must keep a copy of the label, be able to identify which products it covers, and make it available to customers who ask.
Panels shipped into the country only for testing carry a different marking: “For TSCA Title VI testing only, not for sale in the United States.”8eCFR. 40 CFR 770.45 — Labeling That prevents test samples from ending up in commercial channels without certification.
What Downstream Buyers Have to Keep
Importers, fabricators, distributors, and retailers all share a documentation duty. Each must keep bills of lading, invoices, or similar records that include a written statement from their supplier confirming the products are TSCA Title VI compliant. Those records have to be retained for at least three years from the date of import or purchase and produced to the EPA within 30 days of a request.9eCFR. 40 CFR 770.30 — Importers, Fabricators, Distributors, and Retailers
Retailers must also take “reasonable precautions” that the products they sell comply. In practice that means holding the supplier compliance statements and leaving the labels on finished goods intact. Stripping or covering a Title VI label creates a compliance problem for the retailer itself.
Fabricators are in a distinct spot. If you buy compliant panels and assemble them into cabinets, furniture, or similar goods, you do not have to run your own emission tests or go through third-party certification. Your obligations are to buy only compliant panels, label your finished goods properly, and keep supplier documentation for three years.9eCFR. 40 CFR 770.30 — Importers, Fabricators, Distributors, and Retailers That matters for small woodworking shops and custom furniture makers who might otherwise assume expensive lab testing is required.
Violating any Title VI requirement, including selling non-compliant products or failing to keep records, is treated as a violation of TSCA Section 15, with civil penalties reaching $49,772 per violation per day under the current inflation-adjusted schedule and criminal exposure for knowing or willful conduct.10eCFR. 40 CFR 19.4 — Statutory Civil Monetary Penalties, as Adjusted for Inflation That is why the paper trail behind the label matters as much as the label itself.
