US Formaldehyde Emissions Standards for Composite Wood Products – Guide For Panel Manufacturers
SAFEGUARDS | Hardlines NO. 033/17
The US EPA has published a guideline to assist manufacturers/mills to comply with the nation’s law on formaldehyde emissions in composite wood.
In July 2010, we informed  you that President Obama signed ‘The Formaldehyde Standards for Composite Wood Products Act’, into law. This piece of landmark legislation added Title VI to the Toxic Substances Control Act (TSCA) and directed the US Environmental Protection Agency (EPA) to finalize a rule on implementing the law.
In December 2016, the EPA published the Final Rule in the Federal Register. This Rule  includes provisions relating to, among others, formaldehyde emission standards in hardwood plywood veneer core or composite core (HWPW-VC or CC), particleboards (PBs) and medium-density fiberboards (MDFs), third-party certification programs, incentives for products manufactured from ultra low-emitting formaldehyde resins (ULEF) and no added-formaldehyde-based resins (NAF), product labeling, Accreditation Bodies (ABs) and Third-Party Certifiers (TPCs). The formaldehyde emission standards are identical to those in Phase 2 of the Air Toxic Control Measure (ATCM) to control formaldehyde emissions under the California Air Resources Board (CARB) and will become effective on December 12, 2017.
In January 2017, the EPA published a guideline to help panel manufacturers (mills)  comply with the Final Rule. This guide contains a number of important provisions, including:
The relationship between EPA, CARB, CARB-approved TPCs, EPA-recognized ABs, EPA-recognized TPCs and economic operators
A list of exemptions
Incentives for ULEA resins or NAF-based resins used in composite wood products
Product testing requirements
A list of approved quality control test methods demonstrating correlation to ASTM E1333-10. These are ASTM D5582-00, ASTM D6007-02, EN 717-2 (Gas Analysis Method), Dynamic Micro Chamber (DMC) – 2007 or 2012 Georgia Pacific User’s Manual, EN 120:1992 (Perforator Method) and JIS 1460:2012 (24-hour Desiccator Method)
TPCs and Third-Party Certification requirements
Reporting requirements for panel manufacturers
Developing quality control manuals and generating monthly product data reports
Record keeping and product labeling
Enforcement action against violators, including penalties of up to USD 37,500 per violation per day.
It is important to note that the regulations require quality control testing and quarterly testing; the latter of which is conducted by an EPA-recognized TPC. It is also noteworthy that products certified by a CARB-approved TPC are also considered certified under TSCA Title VI, the federal law for formaldehyde emissions in composite wood, until December 12, 2018.
Highlights of the guideline for mills/panel manufacturers relating to formaldehyde emission standards and quality control testing frequency requirements are summarized in Table 1.

Formaldehyde Emissions Standards for Composite Wood Products, Title VI of the TSCA
US EPA, January 2017
|Composite Wood||Emissions Requirement||Quality Control Testing Frequency|
|MDF|| ≤ 0.11 ppm||Once per shift (8 or 12h ± 1h of production) for each production line for each product type|
|Thin-MDF|| ≤ 0.13 ppm|
|PB|| ≤ 0.09 ppm|
|HWPW-VC|| ≤ 0.05 ppm||
|HWPW-CC|| ≤ 0.05 ppm|
|Effective date = December 12, 2017|
