If formaldehyde is not added in the urea production process, methylene diurea is not measured.
Only need to comply with any one of the four gears, the size range should be indicated in the packaging label. If agricultural (fertilizer) urea is used as raw material for blended fertilizer (BB) production, the SGN and UI can be selected according to the supply and demand agreement. For the calculation method, please refer to Appendix A.
