Vietnam Enforces Dual List for Pesticides: Ban + Disclosure

Vietnam’s Ministry of Agriculture and Rural Development (MARD) implemented Circular No. 18/2026/TT-BNNPTNT on May 30, 2026, introducing a mandatory ‘ban + disclosure’ regulatory framework for pesticide and fungicide technical-grade active ingredients. This update directly affects exporters—particularly technical-grade API suppliers in East and North China—and signals tightening regulatory alignment with OECD standards.

Event Overview

On May 30, 2026, MARD officially enforced Circular No. 18/2026/TT-BNNPTNT. The circular establishes two binding requirements: (1) a prohibition list naming 12 N-methylcarbamate-related impurities; and (2) a mandatory submission of a full impurity profile report—certified by an OECD GLP-accredited laboratory—at customs clearance for all imported pesticide and fungicide technical-grade substances. The scope covers all technical-grade pesticides and herbicides, regardless of chemical class or origin.

Industries Affected

Direct Exporters (Technical-Grade API Suppliers)
These enterprises face immediate compliance pressure, as the requirement applies at import declaration. Failure to submit the certified impurity profile will halt customs clearance. Impacts include delayed shipments, increased testing costs, and potential rejections if reports lack required scope or accreditation validity.

Raw Material Sourcing & Intermediate Producers
Suppliers of precursors or intermediates used in synthesizing technical-grade actives may be indirectly affected if downstream customers request updated impurity data traceability. While not directly regulated under this circular, contractual obligations and supply chain audits are likely to extend reporting expectations upstream.

Formulation Manufacturers (Importing Technicals into Vietnam)
Companies blending technical-grade actives into end-use products in Vietnam must now verify supplier documentation prior to import. Their internal quality assurance processes must incorporate review of third-party GLP reports—not just CoA or CoC—to meet MARD’s evidentiary standard.

Supply Chain & Regulatory Support Providers
Logistics firms, customs brokers, and regulatory consultants handling Vietnamese pesticide imports must update documentation checklists and client advisories. They now need to confirm GLP lab accreditation status, report scope coverage (e.g., identification and quantification of all specified impurities), and report issue date relative to shipment timing.

Key Points for Enterprises and Practitioners to Monitor and Act On

Track official MARD guidance on GLP lab recognition

MARD has not yet published a publicly accessible list of accepted OECD GLP laboratories. Exporters should monitor MARD’s official portal and engage local Vietnamese regulatory agents to verify whether their chosen lab is recognized—or pre-qualify labs via MARD’s designated channels before initiating testing.

Confirm coverage of all 12 banned impurities in analytical reports

The circular names 12 N-methylcarbamate derivatives as prohibited—but does not specify analytical methods or reporting thresholds. Enterprises should ensure their GLP reports explicitly identify and quantify each listed impurity, using validated methods (e.g., HPLC-MS/MS), and retain method validation records for possible audit.

Distinguish between policy issuance and operational enforcement timelines

Although the circular entered force on May 30, 2026, initial customs implementation may involve phased verification. Observably, Vietnamese customs authorities may prioritize high-volume or high-risk entries first. Exporters should treat the effective date as binding but prepare for possible early-stage flexibility—and avoid assuming grace periods unless formally announced.

Update procurement and contract terms with Vietnamese importers

Exporters should revise sales contracts and pro forma invoices to include clauses specifying responsibility for impurity profiling, lab selection, and report delivery timing. Where applicable, align payment terms with successful customs clearance—not just shipment—to mitigate financial exposure from non-compliant documentation.

Editorial Perspective / Industry Observation

This circular is better understood as a structural signal than a one-off compliance hurdle. Analysis shows it reflects Vietnam’s broader shift toward harmonizing pesticide regulation with OECD and ASEAN Good Regulatory Practice frameworks—not merely tightening controls, but embedding traceability and analytical transparency into market access. It is not yet evidence of expanded bans beyond the 12 named impurities, nor does it introduce new maximum residue limits (MRLs) or use restrictions. However, observably, it sets a precedent for future extensions—potentially to formulation-level products or additional impurity classes. The requirement for OECD GLP certification also implies growing scrutiny of data integrity across the regional agrochemical value chain.

Consequently, industry attention should focus less on whether this rule applies *now*, and more on whether current quality systems, lab partnerships, and documentation workflows can scale to similar requirements in other ASEAN markets—where regulatory convergence is accelerating.

Conclusion
This circular marks Vietnam’s formal adoption of a dual-layer pesticide regulatory model: proactive prohibition combined with mandatory analytical disclosure. It does not alter existing product registrations or usage approvals, but reshapes the entry conditions for technical-grade inputs. Currently, it is most accurately interpreted as a targeted, enforceable step toward data-driven regulatory oversight—not a broad-based trade barrier, but a calibrated upgrade in evidentiary expectations for market access.
