Thailand’s agricultural regulatory system is under renewed scrutiny after authorities launched an investigation into allegations that a durian export shipment may have been processed using misused Good Agricultural Practices (GAP) certification, a key quality assurance mechanism in one of the country’s most valuable agricultural export sectors.

The probe centers on a shipment reportedly exported on April 26, 2026, from a packing facility in Tha Mai district in Chanthaburi province, a major durian-producing region.

The case was triggered after complaints emerged in China’s wholesale market, where buyers alleged that durians in the shipment showed physical damage consistent with low-grade or improperly handled fruit, including bruising and internal discoloration.

The fruit was described as resembling so-called “fallen durians,” a term used in the industry for fruit that drops prematurely from trees and is typically considered lower quality.

At the core of the investigation is whether the packing house responsible for the shipment improperly used a farmer’s GAP certification to legitimize export documentation.

GAP certification is intended to verify that produce meets standardized agricultural, hygiene, and traceability requirements.

In Thailand’s durian export system, it functions as a key gatekeeping tool linking orchards to export-approved packing facilities.

Authorities have stated that if the certification was misused, the responsible operators could face prosecution under agricultural standards law, and export licences may be suspended or revoked.

Shipping intermediaries and exporters connected to the shipment have also been instructed to provide explanations as investigators attempt to reconstruct the supply chain from orchard to export container.

The investigation is being conducted against the backdrop of Thailand’s heavily export-dependent durian industry, which ships hundreds of thousands of tons annually, primarily to China.

The sector has expanded rapidly over the past decade, but it has also faced repeated allegations involving quality control breaches, including unripe fruit, improper mixing of supply sources, and certification fraud.

These recurring issues have made traceability enforcement a central policy concern for regulators.

Recent enforcement actions suggest tighter scrutiny is already underway.

Earlier inspections in Chanthaburi identified large quantities of durian that failed to meet minimum dry matter standards, a key metric used to determine ripeness and export readiness.

In those cases, authorities ordered the removal of substandard fruit from export channels and warned packing facilities of penalties for repeat violations.

The current case highlights a structural vulnerability in the system: while certification is designed to ensure orchard-level compliance, enforcement depends heavily on packing house integrity and accurate documentation across multiple intermediaries.

Any breakdown in that chain can allow non-compliant fruit to enter export flows while still appearing formally certified.

Regulators have emphasized that the broader export system remains stable, but the investigation signals an effort to reinforce confidence in Thai agricultural exports at a time of intensifying regional competition and rising quality expectations from import markets.

The outcome of the probe is expected to determine whether enforcement shifts from episodic inspections toward more aggressive oversight of packing facilities and certification usage across the durian supply chain, potentially reshaping how Thailand polices its most important fruit export industry.
