Shelled Macadamia Nuts, Fresh or Dried

US buyers commonly specify kernel style (whole, halves, pieces, or granules), moisture content (typically below 1.5%), and peroxide value as a measure of oxidative freshness. Style 0 (whole round kernels) commands the highest premium. Buyers also frequently require aflatoxin and pesticide residue certificates, and some specify country-of-origin or farm-level traceability to meet retailer sustainability requirements.

Macadamia kernels are rich in monounsaturated fats and prone to oxidative rancidity if exposed to heat, light, or oxygen during transit. Best practices include requiring vacuum or nitrogen-flushed packaging, specifying refrigerated or temperature-controlled container shipping for long voyages from East Africa, and testing peroxide value and free fatty acid content upon arrival. Establishing maximum transit-time requirements in purchase contracts is also advisable.
