метрологический учёт

Метрология (Metrology) во внешней торговле specifically refers to the process of measuring and determining physical quantities of goods such as quantity, weight, volume, length, etc., and is a core link in commodity inspection and delivery in international trade. Its application scenarios are extensive, including quantity clauses in contract signing, pre-shipment inspection, re-inspection after arrival, and settlement basis. Precautions: Different countries may use different units of measurement (e.g., metric, imperial, US customary), which must be clearly stipulated in the contract; measurement methods (e.g., gross weight, net weight, conditioned weight, theoretical weight) must also be consistent to avoid disputes; in addition, the measurement error range, weighing instrument calibration, and the validity of third-party notarized inspection (e.g., SGS) must also be specified in advance. Differences from related terms: Metrology focuses on the measurement act itself, while 'Quantity' is the result of measurement, and 'Weight' is a specific dimension of measurement; 'Inspection' has a broader scope, including quality, packaging, etc., and metrology is often part of inspection. Foreign trade practitioners should ensure that measurement clauses are clear and enforceable to prevent disputes over delivery quantity.
