Vietnam Introduces Ban-and-Disclosure List for Pesticide/Biocide Actives; Bio-Plastic Mulch Exporters Must Submit Migration Data

On May 20, 2026, Vietnam’s Ministry of Agriculture and Rural Development (MARD) issued a new regulatory requirement affecting imports of bio-plastic agricultural mulch films and controlled-release packaging. The measure mandates additional reporting on active ingredient migration and prohibits 12 high-risk natural derivatives — triggering immediate supply chain adjustments among exporters, particularly in China’s bio-plastics sector.

Event Overview

On May 20, 2026, Vietnam’s Ministry of Agriculture and Rural Development (MARD) published a regulatory notice requiring all imported agricultural mulch films and slow-release packaging materials containing bio-plastics to submit certified test reports on the migration rates of active ingredients — such as plant extracts or microbial metabolites — into soil or crops. Concurrently, MARD listed 12 high-risk naturally derived substances prohibited for use in such products. The regulation enters into force on July 1, 2026. As of publication, two Chinese bio-plastic mulch exporters have reportedly withdrawn orders due to compliance constraints.

Industries Affected

Direct Exporters of Bio-Plastic Agricultural Films

These companies face immediate customs clearance hurdles. Under the new rule, they must generate and submit third-party migration testing data — a step previously not required for bio-plastic mulch entering Vietnam. Delays or rejections may occur if documentation is incomplete or fails to meet Vietnamese methodological expectations.

Suppliers of Bio-Based Active Ingredients

Manufacturers and distributors of plant-derived or microbially sourced actives used in functional agri-films are affected because 12 listed substances are now banned. Their product portfolios require immediate review against the official prohibition list. If any supplied ingredient appears on the list, formulation adjustments or substitution efforts become necessary before shipment.

Contract Manufacturers & Compounders

Firms that blend bio-polymers with active ingredients for finished mulch films must verify both raw material compliance and final product behavior. Migration testing applies to the end product — not just individual components — meaning compounders bear responsibility for validating performance under Vietnamese soil/crop exposure conditions.

Testing Laboratories & Regulatory Support Providers

Laboratories accredited for migration analysis (especially under Vietnamese-standardized protocols) are likely to see increased demand. However, no official Vietnamese test method has been publicly released yet — creating uncertainty about acceptable analytical parameters, sampling depth, duration, or environmental simulation conditions.

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

Monitor Official Updates from MARD and Vietnam Customs

The prohibition list and migration reporting requirements are confirmed, but technical specifications — including accepted test methods, required detection limits, and report format — remain pending. Stakeholders should track MARD’s official portal and Vietnam’s National Agro-Chemical Registration Portal for updates prior to July 1, 2026.

Identify and Isolate High-Risk Formulations Immediately

Exporters and formulators should cross-check current product formulations against the published list of 12 banned natural derivatives. Any match requires either removal or formal justification — though no exemption pathway is indicated in the May 20 notice. Prioritization should focus on SKUs destined for Vietnam.

Distinguish Between Policy Signal and Operational Readiness

This is a regulatory mandate, not a guidance document — enforcement begins July 1, 2026. However, the absence of finalized test methodology means full operational readiness depends on further clarification. Companies should initiate migration testing now using internationally recognized approaches (e.g., OECD 106/107 adapted for polymer matrices), while treating results as provisional until Vietnamese validation criteria are published.

Prepare Documentation and Supplier Communication Protocols

Exporters should request updated Certificates of Conformance and active ingredient declarations from upstream suppliers. Internal checklists for pre-shipment documentation — including test report metadata (lab accreditation, test standard applied, sample preparation details) — should be drafted and shared across quality assurance and logistics teams.

Editorial Perspective / Industry Observation

Observably, this regulation signals Vietnam’s shift toward function-based regulation of bio-plastic agri-inputs — moving beyond polymer composition to assess real-world biological interaction. It treats bio-plastic films not merely as inert coverings, but as delivery systems for bioactive agents. Analysis shows this reflects broader ASEAN trends toward harmonizing pesticide-related oversight across material categories. From an industry perspective, it is less a one-off compliance hurdle and more an early indicator of how regulators may evaluate next-generation agri-tech materials — especially where biological activity intersects with environmental release. Current attention should focus less on whether the rule will change, and more on how quickly supporting technical frameworks (test standards, lab capacity, interpretation guidelines) mature.

This development underscores a growing regulatory reality: bio-based does not automatically mean low-regulation. For exporters, the distinction between ‘bio-plastic’ and ‘bio-active plastic’ is now operationally decisive in Vietnam — and potentially elsewhere.
