Macadamia Industry Statistics

GITNUXREPORT 2026

Macadamia Industry Statistics

China’s macadamia nut imports topped $700 million in 2023 while EU buyers still face a 4 µg/kg aflatoxin B1 ceiling and oxidation risk that jumps when kernel moisture rises above about 4%. Kenya export strength, multiple new trade hotspots, and a market forecast of roughly 7% CAGR to 2032 are all laid alongside yield, storage targets, and quality drivers that determine which shipments actually make it to retail.

China’s macadamia nut imports pushed past $700 million in 2023 while the US topped $400 million the same year, and Europe’s supply is tightening around quality and aflatoxin compliance with a strict 4 µg/kg limit. Kenya and Australia keep feeding the pipeline, with Kenya exporting 20,000+ metric tons in-shell in 2020/21 and Australia averaging about 30,000 metric tons during 2020/21, yet oxidation risk rises fast when moisture climbs above roughly 4% in storage. The result is a market where trade value, storage chemistry, and regulatory controls move together in ways many summaries miss.
