Australia's Leading cotton classing operation.

Fully independent, we operate two modern cotton classing facilities servicing Australian cotton growers and merchants. The quality of the services at ProClass has always been the benchmark for the industry.

ProClass is Australia's leading fully independent cotton classing operation. We operate a large -scale modern cotton classing facility servicing Australian cotton growers and merchants. Located at Goondiwindi, Queensland, the facility is right in the heart of Australia's traditional cotton belt. At present, ProClass classes approximately 70% of the cotton produced in Australia.

Our mantra is "Professional Independent Classing" and that is exactly what we provide. This is done with the help of a team of industry professionals with long term domestic and international experience, a fleet of the most up to date cotton testing equipment (HVI machines), a state-of-the-art humidification and environment conditioning system and a pro-active, forward thinking Board of Directors.

ProClass is a full participating member of the Cotton Classer's Association of Australia (CCAA). We are fully compliant with the CCAA's Best Management Practice for cotton classing and have been since that program's inception.

In 2016 the Goondiwindi facility was accredited under the International Cotton Association Laboratory Certification Scheme. 

The ProClass service is open to all cotton growers and merchants.

The purpose of the cotton classing

to establish the overall quality of individual bales

The purpose of the cotton classing process is to establish the overall quality of individual bales, using several different parameter measurements. A cotton grower will use their quality information as an important tool when making future agronomic and management decisions.

Australian cotton is all classed using HVI measurements for length. Previously, length was measured on a sample of fibres known as a "pull" when hand classing, and was measured to the nearest 1/32 inch. HVI measures length mechanically in inches, rounded to the nearest 100th of an inch (i.e. 1.17). A beard or tuft of lint is formed by grasping fibres with a clamp.

Fibres are then brushed out and inserted into a chamber with the assistance of a vacuum. The average length of the fibres in the beard (or "Upper Half Mean Length") is measured by infrared. Each sample will be subjected to 2 tests for length with the average of the 2 calculated and reported by the HVI software.
