Scope

This standard specifies the requirements, test methods, inspection rules, labeling, packaging, transportation, and storage for sulfur-coated urea, sulfur-coated slow-release nitrogen fertilizers, sulfur-coated slow-release compound fertilizers, and sulfur-coated slow-release blended fertilizers.
This standard applies to sulfur-coated slow-release fertilizers that use sulfur as the main coating material to wrap granular urea and achieve slow release of nitrogen, which are referred to by various names, including but not limited to sulfur-coated urea, sulfur-coated urea, sulfur-coated urea, sulfur-coated urea, and sulfur-coated urea. It also applies to sulfur-coated slow-release nitrogen fertilizers, sulfur-coated slow-release compound fertilizers, and slow-release blended fertilizers that contain some sulfur-coated urea.
