Last updated: August 2026 dataAnalytical and precision balances with a sensitivity of 5 centigrams or better occupy a specialized niche in laboratory, pharmaceutical, and quality-control environments where exact mass measurement is critical. Classification hinges on the sensitivity threshold: instruments coarser than 5 cg fall outside this heading. These balances are widely traded as standalone units or with calibration weights included, and importers should confirm whether accompanying weights are classified separately under the applicable weights heading or together with the balance.

Only balances capable of detecting differences of 5 centigrams (0.05 g) or less qualify under this heading. Instruments with coarser sensitivity are classified elsewhere in the schedule, so the manufacturer's published readability or sensitivity specification is the key classification determinant.
When weights are imported together with the balance as a set, they are generally classified with the balance under this heading. Weights imported separately are typically classified under their own heading for weights of all kinds, so the shipment configuration matters for correct classification.
