Understanding CARB Phase 2 and E0 Formaldehyde Requirements

Formaldehyde emission limits are the most common source of panel compliance problems for importers, because the requirement differs between destination markets and is enforced at the border.

## Why it matters

Formaldehyde is present in the adhesives used to bond wood panels. Emission limits exist to protect indoor air quality, and they are written into law in several major markets rather than being voluntary guidance.

## CARB Phase 2

The California Air Resources Board Phase 2 standard is the de facto benchmark for panels entering the United States. Composite wood products must be certified as compliant, and the supply chain must be able to produce documentation showing which certified panels were used.

## E0 and E1

The Chinese and European systems grade panels as E1, E0 or the older E2. E1 is the baseline for interior use in most markets. E0 is a significantly lower emission grade and is widely specified for furniture, children’s products and interiors where air quality is a priority.

## What to ask your supplier for

Ask for the emission grade in writing on the order confirmation, and ask for a batch test report with the shipment. A grade claimed verbally and a grade documented on paper are two different things when a customs officer asks a question.

## Our position

All Vitop Wood interior panel ranges can be produced to E1, and most are available in E0 and CARB Phase 2. The grade you specify is stated on the order confirmation and supported by a test report for the batch we ship.
