Fertilizers, mineral or chemical; nitrogenous, double salts and mixtures of calcium nitrate and ammonium nitrate

HS v2022 Code: 310260

About fertilizers, mineral or chemical; nitrogenous, double salts and mixtures of calcium nitrate and ammonium nitrate

HS code 310260 covers a crucial category of fertilizers that are essential for modern agriculture and food production. These nitrogenous fertilizers, which include double salts and mixtures of calcium nitrate and ammonium nitrate, play a vital role in enhancing soil fertility and boosting crop yields. As the global population continues to grow, the demand for efficient and sustainable fertilizers like those under this code has become increasingly important for ensuring food security and supporting the broader agricultural economy.

Production process

The production of fertilizers under HS code 310260 typically involves a multi-step process. Key steps include the synthesis of ammonia, the reaction of ammonia with carbon dioxide to form ammonium carbamate, and the subsequent decomposition of ammonium carbamate to produce ammonium nitrate. The ammonium nitrate can then be combined with calcium nitrate to create the double salts and mixtures covered by this code. Advanced production techniques, such as granulation and coating, may also be employed to improve the fertilizer's physical properties and nutrient release characteristics.

Production inputs

The main inputs required for the production of HS code 310260 fertilizers include natural gas or other hydrocarbon feedstocks for ammonia synthesis, as well as limestone, dolomite, or other calcium-rich materials for the production of calcium nitrate. Specialized production equipment, such as reactors, granulators, and drying systems, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical engineering, process control, and quality assurance.

Production outputs

The primary output of HS code 310260 is a range of nitrogenous fertilizers that can be used to enhance the growth and productivity of various crops. These fertilizers may be consumed by 310210 Fertilizers, mineral or chemical; nitrogenous or 310290 Fertilizers, mineral or chemical; nitrogenous, nes, as well as by 310530 Fertilizers, mineral or chemical; potassic and 310540 Fertilizers, mineral or chemical; containing both nitrogen and phosphorus producers, who may incorporate them into their own blended or compound fertilizer products.
