Pesticide residue testing plays a crucial role in export compliance inspections, directly determining whether agricultural products and food can successfully enter international markets.

Target Country Standards Compliance:Different countries and regions (such as the EU, the United States, Japan, and China) have strict regulations governing maximum residue limits (MRLs) for pesticides. Before export, products must undergo pesticide residue testing to ensure compliance with target market standards; otherwise, they may be directly detained or destroyed.

Avoiding Technical Trade Barriers: Developed countries often restrict imports by raising pesticide residue standards, and testing serves as a key tool to address such barriers.

End-to-end supply chain monitoring

Source Management: Monitor soil, water sources, and pesticide usage during the cultivation phase to proactively manage risks.

Processing Stage Verification: Inspect semi-finished or finished products after processing to ensure no contamination was introduced during production.

Essential Documents for Export ClearanceTest reports are essential documents for import clearance in many countries, certifying that products comply with safety standards (such as the EU's EC 396/2005 regulation and Japan's "Affirmative List System").

Detection Technologies and Methods

Rapid Screening Technology

Enzyme inhibition method: Commonly used for rapid preliminary screening of organophosphorus pesticides in fruits and vegetables, it is low-cost but has limited accuracy.

Immunoassay: High-sensitivity rapid detection for specific pesticides (such as herbicides).

Laboratory Confirmatory Analysis

GC/LC-MS：An internationally recognized high-precision quantitative method capable of simultaneously detecting hundreds of pesticide residues, with results possessing legal validity.

High-throughput detection: Addressing multi-residue analysis demands to enhance efficiency.

Technology and Management Trends

Intelligent Rapid Testing Equipment: Portable mass spectrometers and advancements in sensor technology are enabling on-site screening.

Blockchain Traceability: Achieve full traceability across the entire supply chain through integrated inspection data, enhancing supply chain transparency.

International Mutual Recognition System: Promote international mutual recognition of testing standards and results (such as ILAC and APLAC) to reduce duplicate testing.
