Formaldehyde Limits for Cabinets and Flooring, and What EPA Says About Remodeling Fumes
Code of Federal Regulations, EPA, California Air Resources Board. Data covers Rules and published figures as read November 12, 2026.
Summary
Federal law caps formaldehyde emissions from the composite wood used in cabinets, flooring and trim: 0.05 parts per million for hardwood plywood, 0.09 for particleboard, 0.11 for MDF and 0.13 for thin MDF. The limits match California's. Separately, EPA says levels of some organic chemicals can reach 1,000 times outdoor background during and just after activities such as paint stripping.
Federal law caps formaldehyde emissions from composite wood products at 0.05 parts per million for hardwood plywood, 0.09 for particleboard, 0.11 for medium-density fiberboard (MDF) and 0.13 for thin MDF. Source [1]
The federal limits are the same as California's: the California Air Resources Board states that "the TSCA Title VI and CARB formaldehyde emission standards are the same." Source [3]
Since March 22, 2019, composite wood products must be labeled as TSCA Title VI compliant, according to EPA. Source [2]
Finished goods covered by the composite wood rules include cabinets, doors, furniture, flooring products, moldings, shelving and countertops, according to the California Air Resources Board. Source [4]
EPA's Total Exposure Assessment Methodology study found levels of about a dozen common organic pollutants to be 2 to 5 times higher inside homes than outside. Source [5]
EPA says that during and for several hours immediately after activities such as paint stripping, levels of organic chemicals "may be 1,000 times background outdoor levels." Source [5]
| Product | Federal limit | California Phase 2 limit |
|---|---|---|
| Hardwood plywood | 0.05 ppm | 0.05 ppm |
| Particleboard | 0.09 ppm | 0.09 ppm |
| Medium-density fiberboard (MDF) | 0.11 ppm | 0.11 ppm |
| Thin MDF | 0.13 ppm | 0.13 ppm |
- Federal limits were read from the current text of 40 CFR 770.10. California limits are from the Air Resources Board's regulation order and its comparison with the federal rule.
- Indoor air statements are quoted from EPA's page on volatile organic compounds and indoor air quality.
- EPA issued a final rule in October 2026 updating the test standards referenced in the regulation. EPA's summary describes changes to test standards, not to the limits; the Federal Register notice itself was not read.
- The limits are emission test results for the panel material, not air concentrations in a finished room.
- The "2 to 5 times" figure is from an EPA study completed in 1985.
- EPA gives no numeric indoor standard for volatile organic compounds in homes and states that not much is known about health effects at the levels usually found in homes.
