- Abundant phosphate resources: strong upstream support for phosphates.
- Established chemical industry: mature production technologies and large-scale plants.
- Cost advantage: integrated production and relatively lower labor and operating costs.
- Export experience: many factories have long experience exporting to Asia, Europe, Africa, and Latin America.
