Oil sunflower seeds (Helianthus annuus) are the primary oilseed crop in Russia. Oil content 44–52%. Sunflower oil is the most consumed vegetable oil on the domestic market. Linoleic acid (Omega-6) 55–65%, oleic acid 20–30%. High-oleic hybrids (HO) – oleic acid up to 85% for frying and industrial applications. Moisture up to 8%. GOST 22391-2015. By-products: sunflower meal (protein 39–42% DM) and cake, hulls (fuel, substrate). Main growing regions: Krasnodar Krai, Rostov, Voronezh, Saratov Oblasts. Sunflower is Russia's main oilseed crop: sown area over 9 million hectares, gross harvest 15–17 million tons. Russia is the world's largest exporter of sunflower oil (over 4 million tons/year). Processing: pressing → unrefined oil (cold-pressed, for retail) + cake (fat 7–12%). Extraction → crude oil (for refining) + meal (fat 1.5%). Refining: hydration → neutralization → bleaching → deodorization → winterization. By-products: hulls (ash content 2–4%) – fuel for boiler houses at oil extraction plants, substrate for mushroom cultivation. Meal (protein 39–42% DM) – the world's second-largest feed meal by volume after soybean. Seed storage: moisture ≤7%, temperature ≤25°C. Prone to self-heating at moisture >8%. Shipment: grain trucks, hoppers, containers. Export documentation: phytosanitary certificate, quality protocol. Storage: dry ventilated warehouses, temperature and humidity control. Products undergo incoming quality control for each batch. Test reports from accredited laboratories. Shipment: road transport, railway wagons, 20/40 ft containers. Minimum order quantity agreed individually. Export supplies to EAEU countries, China, the Middle East, Africa, Southeast Asia. Flexible payment terms: prepayment, letter of credit, CAD (documents against payment). Logistics: port terminals of Novorossiysk, Rostov, Azov – for vessel shipments. Container terminals of Moscow, Yekaterinburg – for container shipments.
