The world shears only half the wool it did in 1990, and nearly three-quarters of traded raw fleece goes to Chinese mills.

Where it comes from

Chart: Map of where it comes from

Wool is grown, not mined: sheep are shorn about once a year. Fine Merino comes from dry pastures in Australia and South Africa. The world clip was 1.70 Mt in 2024.

Three things to know
  1. World greasy wool output roughly halved, from 3.35 Mt in 1990 to 1.70 Mt in 2024, as synthetics took market share.
  2. Australia supplied 65.9% of greasy wool export value in 2024, and China took 73.4% of imports.
  3. Australia's reserve price scheme collapsed in 1991 with a huge stockpile that took years to sell.
