Import Tips

• Processing records must prove calcination beyond mere impurity removal to justify Chapter 31 shift

• Radioactivity testing often required for phosphate rock derivatives; comply with NRC guidelines

• Declare exact calcination temperature and duration to distinguish from raw mineral products
