Trade measurement refers to buying and selling of goods and services where the value is determined by measurement.
Studies in Australia, the USA and Canada have estimated that the total value of trade transactions involving measurement (including packaged goods and utility metering) accounts for at least 50% of Gross National Income. Of this amount, around a quarter is accounted for by retail transactions with the remaining three quarters being business to business transactions. Based on these estimates, the total value of trade transactions involving measurement in Australia is currently more than $750 billion a year.
Consistency and certainty in measurement supports fair and open competition. It provides a level playing field for business by ensuring that all market participants, irrespective of their size or financial strength, follow the same rules and have equal opportunity to compete.
Reliable representations of measurements help consumers and businesses make informed purchasing decisions. More broadly, they support the efficient operation of the market.
