• Require calibration certificates and chemical compatibility data to substantiate classification as instrument-specific parts
• Declare exact electrode type (glass, ISFET) and compatible instrument models to prevent reclassification as consumables
• Ensure proper hazardous materials declarations for electrolyte-filled electrodes during shipping
