Are you ready? Formaldehyde regulation starts from January 2023, in Canada

In July 2021, the Minister of the Environment in Canada published, Formaldehyde Emissions from Composite Wood Products Regulations"(SOR/2021-148) established under the authority of CEPA,1999.

This regulation comes into force on January 7, 2023.By the regulations, composite wood products exceeded the emission limits will be prohibited for sale, offer for sale or import.

Formaldehyde is well known as the carcinogenic and the formaldehyde emission from certain composite wood products effects indoor air. The purpose of implementing the regulation is to reduce formaldehyde exposure in indoor air and the risk of health damage associated with this exposure.

Regulatory Products

1.Hardwood plywood

It is decorative panel that is manufactured for non-structural applications and that is made from plies of veneer that are glued to a core of composite or *veneer or a combination of composite and veneer. *Veneers ・・・A sheet of wood or woody grass with a maximum thickness of 6.4 mm that is rotary cut, sliced or sawed from a log.

2. Particleboard

It is a panel composed of discrete particles of cellulosic material consolidated under pressure with resin but does not include a panel composed of cellulosic material made from fibres, flakes or strands. 

3. Medium density fiberboard (MDF)

It is a panel that is greater than 8 mm in thickness and that is composed of cellulosic fibres made by dry forming and dry pressing a resinated fibre mat but does not include *hardboard.

*Hardboard・・・A panel composed of cellulosic fibres, consolidated under heat and pressure in a hot press by one of the following processes:

• A wet process
• A dry process that uses phenolic resin or a resin in which there is no formaldehyde as part of the resin cross-linking structure.
• A wet-formed and dry-pressed process.

4. Thin-Medium density fibreboard

It is a panel that has a maximum thickness of 8 mm and that is composed of cellulosic fibres made by dry forming and dry pressing a resinated fibre mat but does not include hardboard. 

5. Laminated product

It is composed of a *veneer that is glued to a core or platform consisting of a composite wood panel or veneers.

Formaldehyde Testing and Emission limits

Testing

Applicable products are required two types of tests - Primary testing (Testing of emission limits) and quality control testing. The primary tests must be conducted four times annually by an *accredited laboratory. (According to the American Society for Testing and Materials, ASTM E1333 or, ASTM D6007). Furthermore, test results must be validated by a *third-party certification.

*Accredited laboratory: under the International Organization for Standardization standard ISO/IEC 17025.

*Third-party certification: It is accredited under the International Organization for Standardization standard ISO/IEC 1706

Emission limits

NOTE: As regards laminated product, the following products are exempted:

1.In the case of a product type whose core or platform is a composite wood panel, formaldehyde emissions from the core or platform, prior to incorporation into the laminated product, do not exceed the applicable limit- 0.05ppm.

2. In the case the veneer is glued to the core or platform using a phenol-formaldehyde resin or a no-added-formaldehyde resin.
