Single Super Phosphate (SSP)

SSP 16–20% P₂O₅ with calcium and sulphur, granular and powder

Single super phosphate is phosphate rock treated with sulphuric acid, the oldest manufactured fertilizer and still the cheapest way to deliver phosphate together with sulphur and calcium. Producer and trade specifications put available P₂O₅ at 16–20%, with sulphur at about 11–12% and calcium at 18–21%; granular grades carry moisture of a few percent and 90–95% of granules within about 2–4.5 mm, while powder SSP is sold to blenders and local markets. Buyers who price SSP only on P₂O₅ find it expensive against DAP or TSP; buyers growing oilseeds, pulses, pasture or sugarcane on sulphur-deficient soils count the sulphur too and often find it the better value. Contracts name available and water-soluble P₂O₅, free acid, moisture and size.

UN Comtrade 2024 data put reported SSP exports (HS 3103.19, superphosphates below 35% P₂O₅) at about USD 0.53 billion, led by China (46.2%) and Egypt (16.7%), with India (6.0%), Spain, Uzbekistan and Poland behind; most SSP is made and used domestically, so the export trade is small, bagged-heavy and regional. SSP is a phosphate fertilizer and falls under the EU Fertilising Products Regulation 2019/1009 cadmium limit of 60 mg per kg P₂O₅ for EU fertilising products. CBIL brokers SSP against an SGS, Intertek or Bureau Veritas certificate of analysis for available and water-soluble P₂O₅, sulphur, free acid, moisture, size and, where required, cadmium, with a certificate of origin, in bulk, 50 kg PP bags and jumbo bags. Prices are negotiated per MT on grade, with published phosphate assessments from Argus, CRU and Fertilizer Week as reference points.
