Formaldehyde emission standard

What is CARB2, and why does it matter for your cabinets?

CARB2 is the strictest formaldehyde emission standard for composite wood in the United States. Every cabinet we ship meets it - so the wood in your kitchen is held to the cleanest air-quality limit on the market.

The basics

What CARB2 actually means

A plain-English look at the standard, where it came from, and what it controls.

CARB stands for the California Air Resources Board. In 2007 it set the first U.S. limits on how much formaldehyde composite wood products are allowed to release into the air - a two-stage rule rolled out as Phase 1 (CARB1) and the tighter Phase 2 (CARB2).

Formaldehyde is a chemical used in the glues that bind plywood, particleboard, and MDF. Over time those panels can off-gas it indoors. Because kitchen cabinets are built largely from composite wood, they fall squarely under the rule.

In 2018 the federal TSCA Title VI standard adopted the same emission limits nationwide - so CARB2 is no longer just a California rule. It's the benchmark for composite wood across the entire country.

"CARB2 caps formaldehyde from hardwood plywood at 0.05 ppm - the cleanest composite-wood air limit set in the U.S."
If a product can't show it meets that number, it can't legally be sold as compliant.
Federal standard

What does TSCA Title VI compliant mean?

TSCA Title VI is the federal law that adopted CARB2's formaldehyde limits nationwide in 2018. If a cabinet is TSCA Title VI compliant, its plywood, particleboard, and MDF were certified to emit no more than the CARB Phase 2 limits - 0.05 ppm for hardwood plywood and 0.11 ppm for MDF. Every cabinet we sell meets both.

Phase 1 vs Phase 2

Two stages, one goal: less formaldehyde

Phase 2 tightened the limits Phase 1 introduced. It's the level required today - and the level we build to.

Phase 1 · 2009

CARB1

0.08 ppm · hardwood plywood

The first stage. It introduced emission caps and got the industry moving, but allowed higher formaldehyde levels than the standard in force today.

Today's standard Phase 2 · 2010+

CARB2

0.05 ppm · hardwood plywood

The stricter stage, now mirrored by federal TSCA Title VI. Lower caps across plywood, particleboard, and MDF. This is the level every Buy Wholesale Cabinets product meets.

Why it matters

What compliance buys you

CARB2 isn't paperwork for its own sake. It changes what's in the air at home, what you can legally install, and what a project is worth later.

Cleaner indoor air

Lower formaldehyde emissions mean less off-gassing in the room you cook, eat, and gather in every day.

Legal to sell & install

Non-compliant cabinets can't legally be sold in California and many other markets. Compliance keeps your project clear of trouble.

Resale & permit ready

Documentation backs up inspections and resale. You can hand the certs straight to your contractor or building department.

Common questions

CARB2, answered

Is CARB2 only a California requirement?
No. It started in California, but since 2018 the federal TSCA Title VI standard adopted the same emission limits nationwide. CARB2-level compliance is the benchmark for composite wood products across the United States.
What does TSCA Title VI compliant mean?
TSCA Title VI is the federal law that adopted CARB2's formaldehyde limits nationwide in 2018. Compliant cabinets use plywood, particleboard, and MDF certified at or below 0.05 ppm (hardwood plywood) and 0.11 ppm (MDF).
What's the difference between CARB1 and CARB2?
CARB1 (2009) allowed up to 0.08 ppm formaldehyde from hardwood plywood; CARB2 tightened it to 0.05 ppm. CARB2 is the level required today and the level every cabinet we sell meets.
Are all your cabinets CARB2 compliant?
Yes. Every plywood, particleboard, and MDF panel in every cabinet we ship meets CARB Phase 2 and TSCA Title VI emission limits, on every order.
Can I get compliance documentation for my project?
Yes. We provide compliance documentation on request and can send certificates directly to you, your contractor, or your building department for permits and inspections.
