Weekly Nut Market Briefing
Over the past week, the global nut sector – especially macadamias – has been shaped by three major themes: a reshuffling of supply origins, a spike in food safety incidents, and sustained momentum in health‑driven consumption.
Over the past week, the global nut sector – especially macadamias – has been shaped by three major themes: a reshuffling of supply origins, a spike in food safety incidents, and sustained momentum in health‑driven consumption.
Macadamias: China Drives Production, South Africa Seeks Growth Amid Uncertainty
Latest industry data show that global macadamia production continues to rise, with China’s in‑shell output already exceeding 100,000 tons, making it one of the key engines behind global volume growth. At the same time, South Africa remains the world’s largest macadamia exporter, but 2025 output there is forecast to fall by around 4% versus last season due to adverse weather and smaller nut size, putting pressure on export structure and margins.
In Australia, final volumes are better than mid‑season worst‑case scenarios, yet growers in New South Wales and Queensland still describe 2025 as one of the “leanest years in a decade,” with only new orchards coming into bearing providing incremental tonnage. On the trade side, South Africa has long relied heavily on the US market, but with US plans to impose tariffs of around 30% on certain macadamia products from August 2025, exporters are accelerating their pivot toward China, India, ASEAN, and the Middle East to spread risk.
China’s Tree Nuts: Imports Contract, Domestic Supply Rises, Macadamias Run on “Dual Engines”
According to the latest “China: Tree Nuts Annual,” China’s domestic tree nut output (including walnuts, macadamias, hazelnuts, etc.) has grown at a compound rate of about 9% over the past five years, significantly strengthening local supply. In macadamias and walnuts in particular, intensive development in Yunnan and Guangxi is gradually replacing part of China’s historical dependence on imports.
On the import side, China’s tree nut imports exceeded 600,000 tons in 2024, up 21% year‑on‑year, but in the first half of 2025 overall tree nut imports fell by roughly 38%, mainly due to additional tariffs on US products and macro‑economic headwinds. For domestic processors and brands, this raises the strategic value of stable, traceable domestic raw material, as secure upstream access increasingly translates into bargaining power downstream. For overseas suppliers, winning in China will depend more on differentiation (organic, origin branding, certifications) and value‑added formats (kernels, pieces, oils) rather than simply shipping bulk in‑shell product.
Food Safety: Nut Recalls Underscore the Need for Strong QA and Traceability
Over the past week, multiple nut‑related recalls in North America have once again pushed “food safety” and “traceable supply chains” to the forefront.
A major warehouse club in the US issued an urgent recall on a Hawaii‑region “Hawaiian‑style macadamia baking product” after the supplier’s internal testing detected potential Salmonella contamination, with members instructed to stop consumption and offered full refunds.
A national supermarket chain recalled two mixed nut products sold across nine states, also over possible Salmonella risk; although no confirmed illnesses had been reported, the retailer proactively pulled products and opened returns as a precaution.
For exporters and brand owners, these incidents send several clear messages:
Retailers and regulators are increasingly “zero‑tolerance” on microbiological and allergen risks, pushing stricter requirements on testing, preventive controls, and process hygiene upstream.
Suppliers with robust traceability systems, third‑party certifications, and a clean track record are better positioned to secure listings with large chains and to build a “safe and reliable” reputation when incidents hit the headlines.
Health‑Driven Demand: National Dietary Guidelines Continue to Endorse Nuts
On the consumption side, several official and semi‑official bodies continue to promote higher nut intake and lower red‑meat consumption as part of healthier and more sustainable dietary patterns, providing policy‑level support for long‑term nut demand. For example, recently updated national dietary guidelines emphasize reducing meat, while increasing legumes and nuts to improve both health outcomes and environmental impact.
This dovetails with market research from the US and Europe showing that flavored nuts, nut beverages, nut butters, and high‑protein nut snacks remain key growth segments, with tree nuts such as almonds, walnuts, and macadamias standing out thanks to their strong “health halo.” Product and content strategies built around “good fats, low sugar, functionality” and “organic plus eco‑friendly packaging” are expected to stay central in winning consumer mindshare over the next few years.
Three Practical Takeaways for Industry Players
Diversify origins and portfolios to hedge single‑market risk.South Africa, Australia, China, and Kenya each face distinct challenges in yield, quality, and policy; multi‑origin, multi‑spec setups help smooth supply volatility and tariff shocks.
Treat safety and certification as infrastructure, not marketing.This week’s recalls highlight that pesticide residues, microbiological control, and cross‑contamination management are now part of the basic “license to operate,” not optional extras.
Use “health + story” to explain premium macadamias and other high‑value nuts.In an era of health and plant‑based eating, macadamias and premium walnuts can move from “tasty snacks” to “everyday nutrition solutions” when backed by clear data, origin stories, and usage occasions that justify their price.
