Quality Sampling
Standardized units of compressed cotton fibre formed after the ginning process provide the primary vehicle for the international trade and transport of the crop. Each raw cotton bale is wrapped in protective bagging and secured with metal or plastic straps to maintain its shape and density. The weight and dimensions of these units vary by country of origin, but they are all designed for efficient loading into shipping containers.
Grade Assessment
Lint Quality. Technicians extract samples from both sides of the unit to determine the colour, leaf content and staple length of the fibre. These results are recorded on a permanent tag that stays with the package until it reaches the spinning mill.
Physical Density
Storage Requirement. High pressure compression is used to reduce the volume of the lint, making it possible to fit more weight into a truck or vessel. If the strapping breaks, the expansion of the fibre can damage the surrounding cargo or the structure of the warehouse.
Commercial Value
Trading Basis. Contracts for the sale of the fibre specify the price per pound or kilogram based on the net weight of the delivered units. Deductions are made for the weight of the wrapping material and the bands during the final invoicing.
