Sealing and testing of instruments of weights and measures
All instruments for determining weights and measures in all consumer related transactions are required to be tested, calibrated, and sealed every six months by the official sealer who must be the provincial, city, municipal treasurer (or his authorized representative) upon payment of fees required under existing law. Such instruments are to be continuously inspected for compliance with the provisions of the law.
Best Legal Practices
Obtain seal from the concerned local government unit – Businesses engaged in weighing and measuring consumer related transactions should obtain the official seal from the concerned local government unit. Thereafter, such seal should never be tampered as the same will be inspected regularly.
