Weighing/measuring instrument verification
This is a genuine edge case — most bars, restaurants and cafes never trigger it.
Not yet independently verified — check the source link: The applicability trigger (charging customers by weight counting as "trade use") is confirmed in principle, but the specific fee schedule for instrument verification was not confirmed this pass.
This is a genuine edge case — most bars, restaurants and cafes never trigger it. It applies only to businesses that sell goods by weight, for example a deli counter charging per 100g. Any weighing or measuring instrument used for that kind of trade must be periodically verified and stamped by the Weights and Measures Office.
Using an unverified instrument for trade is an offence under the Weights and Measures Act, and it undermines customer trust in what they are actually being charged for.
Who this is for
Venues that charge customers based on weight, such as a deli or salad bar priced per 100g. Most bars, restaurants and cafes do not trigger this.
What you’ll hold
- Instrument verification/stamp certificate
Watch out for
- Assuming a kitchen scale used only for recipe measurement counts as "trade use" — it does not, unless customers are charged directly by weight.
- Missing re-verification because the instrument is rarely thought of as a compliance item alongside food safety or fire checks.
- Buying a scale without confirming it is an approved, verifiable type before relying on it for customer pricing.
