Weights and Measures Office

Suppliers or importers of weighing and measuring instruments

Register your weighing or measuring instrument's pattern with the Weights and Measures Office before use in trade in Singapore.

Last updated 25 May 2026

For suppliers or importers of weighing and measuring instruments

Suppliers of weighing and measuring instruments to be used for trade in Singapore, must show proof that your instruments have undergone various tests and are in compliance with the relevant international standards, to attest that the instruments can maintain their accuracy under different types of operating conditions.

Weighing or measuring instruments used for trade in Singapore must have their pattern or type registered with the Weights and Measures Office before they can be used in Singapore. Examples of such instruments may be found in the Singapore Weights and Measures information booklet. The pattern of a weighing and measuring instrument refers to the design of an instrument with all components affecting its measurement properties suitably specified.

By registering the pattern of the weighing and measuring instrument, it ensures that no substandard design of weighing and measuring instruments for trade use are used in Singapore.

In addition, weighing or measuring instruments which are manufactured for use for trade purposes, must have in their instruction or operation manuals/leaflets, a statement advising users to seek approval from their national weights and measures authority before these instruments can be used for trade purposes.

Application procedure

You may apply for pattern registration of weighing and measuring instruments through the application form for pattern registration. The Weights and Measures Office will process the application once all required supporting documents have been received and verified. You can expect to hear about the outcome within 30 working days from that point. If you have any questions during this process, please contact us through our online form.
