Fibre Length / Strength / Micronaire (HVI)

High Volume Instrument (HVI) testing measures cotton fibre length, strength, micronaire (fineness) and related parameters in one automated pass.

Why exporters need it

HVI results are the internationally standard way cotton is graded and priced, and Tanzania's own HVI capacity is one of its strongest documented testing assets.
