T/GVEAIA 031.5-2026 Rare Earth Intervention in Agricultural Product Production Regulation Part 5: Test Methods

Scope

This document specifies the inspection classification, batching and sampling, rare earth residue detection, flavor quality detection, physical and nutritional testing, safety indicators, and result determination and re-inspection requirements for agricultural products regulated by rare earth intervention in their production. This document applies to the quality inspection of rare earth-regulated agricultural products, including vegetables, fruits, grains, tea, edible fungi, and medicinal plants, as stipulated in the T/GVEAIA 038 series standards. This document provides testing method support for the limit indicators specified in T/GVEAIA 031.2 (Technical Requirements) and provides a basis for the graded inspection of the T/GVEAIA 038 series standards. 4. Inspection Classification 4.1 Type Inspection 4.1.1 Trigger Conditions The following circumstances require type inspection: - First production of a new product or transfer of production to a new factory for an existing product; - Significant changes in raw materials, processes, or equipment that may affect product quality; - Resumption of production after a hiatus of more than 6 months; - Requirement for type inspection by national quality supervision authorities; - At least once annually during normal production. 4.1.2 Inspection Items Includes all items specified in Chapters 6-9: - Rare earth residue (total rare earth + individual elements); - Flavor quality (five flavor intensities + characteristic substances); - Physical and nutritional properties (soluble solids, sugars, acids, vitamin C, etc.); - Safety indicators (heavy metals, pesticide residues, microorganisms). 4.2 Factory Inspection 4.2.1 Inspection Items Every batch of products must undergo the following inspections before leaving the factory: - Sensory inspection (appearance, flavor, defects); - Net content (compliance with JJF 1070); - Target flavor characteristic substances (e.g., soluble solids for sweet tomatoes); - Rapid screening of rare eart
