Vietnam Tightens Formaldehyde Limits for WPC Backdrops Effective May 1, 2026

On April 18, 2026, Vietnam’s Ministry of Industry and Trade (MOIT) issued Decision No. 28/QĐ-BCT, tightening formaldehyde emission limits for wood-plastic composite (WPC) backdrops widely used in wedding photography. The new limit—0.05 mg/m³, aligned with EN 717-1:2023—replaces the previous standard of 0.124 mg/m³ under TCVN 7722:2019. Enforcement begins May 1, 2026. Exporters of WPC products from China—and other third countries supplying Vietnam—must now ensure compliance through EN 717-1:2023 testing and update VINAFOOD/QUATEST certification documentation prior to shipment. This development directly affects manufacturers, exporters, and certification service providers engaged in the WPC backdrop supply chain to Vietnam.

Event Overview

On April 18, 2026, the Vietnamese Ministry of Industry and Trade (MOIT) published Decision No. 28/QĐ-BCT, amending the formaldehyde emission limit for wood-plastic composite (WPC) decorative backdrops. The revised limit is set at 0.05 mg/m³, equivalent to EN 717-1:2023. This replaces the prior limit of 0.124 mg/m³ specified in TCVN 7722:2019. The regulation takes effect on May 1, 2026. Affected products are specifically those used as photographic backdrops in wedding studios. Exporters must obtain EN 717-1:2023-compliant test reports and revise their VINAFOOD or QUATEST certification files before customs clearance in Vietnam.

Which Subsectors Are Affected

Direct Exporters (China-based WPC manufacturers and trading companies)
These entities face immediate regulatory pressure, as shipments arriving in Vietnam after May 1, 2026 will be subject to verification against the new limit. Non-compliant consignments may be rejected or require retesting, causing delays and added costs. The requirement to update VINAFOOD/QUATEST certification files means export documentation workflows must be revised before shipment—not after arrival.

WPC Material Suppliers and Compounders
Suppliers providing base materials or formulations for WPC backdrops must verify whether their current resin systems, binders, or formaldehyde-scavenging additives meet the stricter 0.05 mg/m³ threshold under EN 717-1:2023 conditions (climate chamber method). A formulation compliant with older standards may not pass the updated test protocol—even if raw material formaldehyde content appears low.

Certification and Testing Service Providers
Laboratories accredited for VINAFOOD/QUATEST support must confirm capability to perform EN 717-1:2023 testing—including proper chamber calibration, sampling procedures, and analytical methods (e.g., spectrophotometric detection per ISO 12460-3). Clients relying on outdated test reports (e.g., based on TCVN 7722:2019 or ASTM D6007) will need to resubmit samples under the new protocol.

What Relevant Enterprises or Practitioners Should Focus On — And How to Respond

Verify current test reports against EN 717-1:2023 methodology—not just numerical thresholds

EN 717-1:2023 specifies precise chamber conditions (temperature, humidity, air exchange rate) and sampling intervals. A report citing “0.05 mg/m³” but generated using non-standardized or non-accredited lab procedures does not satisfy MOIT requirements. Exporters should request full test protocols and accreditation scope statements from labs.

Update VINAFOOD/QUATEST file submissions before May 1—not after shipment

Certification bodies require documented evidence of EN 717-1:2023 compliance prior to issuing updated certificates. Delays in submission may halt customs clearance. Companies should allocate at least 10–14 working days for lab testing + documentation review + certificate reissuance—especially if initial results exceed the new limit and reformulation is needed.

Confirm which product variants fall under the scope—beyond ‘wedding backdrop’ labeling

The regulation targets WPC products used as photographic backdrops in studio settings. However, MOIT’s classification may extend to similar WPC panels marketed for interior decoration or event staging if functionally interchangeable. Exporters should assess product descriptions, packaging labels, and commercial invoices to avoid misclassification during customs inspection.

Editorial Perspective / Industry Observation

From an industry perspective, this change signals Vietnam’s broader alignment with EU-aligned chemical safety benchmarks—not merely a technical adjustment. Analysis来看, the shift from TCVN 7722:2019 to EN 717-1:2023 reflects a move toward harmonized test methodologies rather than isolated limit-setting. Current更值得关注的是 how strictly Vietnamese customs and QUATEST inspectors will enforce the transition period: while the rule takes effect May 1, enforcement clarity around grandfathering of pre-May stock remains unconfirmed. Observation来看, this is less a standalone policy shift and more part of a pattern—Vietnam has incrementally tightened formaldehyde limits across multiple wood-based product categories since 2022. It is better understood as a regulatory signal reinforcing long-term compliance expectations, rather than a one-off compliance hurdle.

Conclusion

This regulation marks a concrete step in Vietnam’s formalization of indoor air quality controls for decorative building and studio products. Its significance lies not only in the tighter numeric limit, but in the mandated adoption of a specific, internationally recognized test standard—introducing procedural rigor beyond simple threshold enforcement. For affected stakeholders, the most rational interpretation is that this is a binding operational requirement, not a provisional guideline. Preparedness hinges on verifying test validity, updating certifications proactively, and confirming scope applicability—rather than waiting for enforcement precedents to emerge.
