E0.5, E1 and E2 Formaldehyde in Plywood: What European Importers Must Know

Formaldehyde emission class is a mandatory specification for plywood and MDF sold into most European markets — and increasingly into other regulated markets worldwide. Getting it wrong means product rejection at customs, retailer returns, or regulatory fines.

This article explains the difference between E0.5, E1 and E2, what test methods apply, and what to request when ordering Brazilian pine plywood or MDF.

The emission classes

Class	Limit (EN 717-1 chamber method)	Typical application
E0.5	≤0.5 mg/m³ air	Premium EU interior, Scandinavian markets
E1	≤1.5 mg/m³ air	Standard EU interior — most common
E2	≤5.0 mg/m³ air	Industrial/outdoor only — not for interior use

The old E0 class (≤0.12 mg/L perforator method) has largely been replaced by E0.5 under the revised EN ISO 12460 test standards. When suppliers refer to "E0," they typically mean ≤0.5 mg/m³ air under the new method.

Test methods: chamber vs perforator

You will encounter two test methods in documentation:

EN 717-1 (gas analysis / chamber method) — The current EU standard. Results in mg/m³ of air. Used for CE marking and most European trade.

EN 120 (perforator method) — Older method giving results in mg/100g dry board. Still used in some markets and by some suppliers. Not directly comparable to chamber results.

When reviewing certificates, confirm which method was used. A result of "0.5 mg/100g" (perforator) is not the same as "0.5 mg/m³" (chamber).

Which class does your market require?

Market	Required class	Notes
EU (general interior)	E1	Mandatory under EN 13986 for CE marking
Germany (BlueAngel)	E0.5	Stricter voluntary scheme for "premium" products
Scandinavia	E0.5	Retailer policies often demand this
UK (post-Brexit)	E1	Retained EU standards
USA	CARB P2	Separate standard — see CARB P2 article
Australia	E1 equivalent	AS/NZS 4266
Middle East	E1 or none	Varies by country and end use

How to specify correctly

When placing an order, state:

1. The emission class required: E0.5 or E1
2. The test method: EN 717-1 (chamber) preferred
3. The certifier: SGS, BV, or Intertek acceptable
4. Whether CE marking documentation is needed
