Import Tips
• Document filtration level (e.g
• cellulose content <10%) to confirm semi-refined status and avoid Chapter 35 starch classification
• Test for iodine value and gel strength to meet importer specs and prevent quality-based rejections
• Use ventilated containers to prevent mold during ocean transit, common with higher-moisture semi-refined products
