Australia remains the world's largest exporter of macadamias, accounting for 46 percent of total world exports. Connect2India also provides information on how to export macadamia nuts and current data on macadamia nuts. For research purposes, the 6-digit Harmonized Tariff System prefix is 080261 for fresh or dried macadamia nuts in shell and 080262 for fresh or dried unshelled macadamia nuts. Compared to other common edible nuts, such as almonds and cashews, macadamias are high in total fat and relatively low in protein.
The macadamia tree is usually propagated by grafting and doesn't start producing commercial quantities of seeds until it's 7 to 10 years old, but once established, it can continue producing for more than 100 years. A reference amount of 100 grams of macadamia nuts provides 740 kilocalories and are a rich source (20% or more of the daily value (DV)) of numerous essential nutrients, such as thiamine (104% DV), vitamin B6 (21% DV), other B vitamins, manganese (195% DV), iron (28% DV), magnesium (37% DV) and phosphorus (27% DV) (table). Macadamia is known to be a good source of manganese, vitamins A and B, folic acid, healthy fats, antioxidants, and proteins. Macadamias prefer fertile, well-drained soils, a rainfall of 1000 to 2000 mm (40 to 80 inches) and temperatures that do not fall below 10 °C (50 °F) (although once established, they can withstand light frosts), with an optimal temperature of 25 °C (80 °F).
Although Australia is one of the leading producers of macadamia nuts, their consumption is significantly lower compared to the U.S. U.S. and China. Macadamia nuts are rich in selenium, a valuable antioxidant that boosts the quality of blood flow, resistance to diseases and defends against inflammation.
Large-scale commercial macadamias products began in the 1880s in Hawaii, when Australian seeds were planted. The downside is that macadamias don't fall off the tree when they're ripe and the leaves are a little prickly when you get inside the tree during harvest. Demand for macadamia oil is leading the demand, as walnut oil is considered to be one of the best in the world. The first commercial macadamia orchard was planted in the early 1880s by Rous Mill, 12 km (7.5 miles) south-east of Lismore, New South Wales, and consisted of M.
By 2030, China is expected to be the world's largest producer of macadamia, as the country's farmers are dedicated to harvesting. Therefore, the following statistics show the surplus between the value of macadamia nuts exported by each country with India and its import purchases for that same product.
