Import Tips

Verify starch content exceeds Chapter 11 minimum via Ewers method and ash under limits to avoid reclassification to 2302

Provide mill certificates showing sieve passage for powder fineness; common pitfall is contamination with non-potato starches

Label clearly as 'potato flour' not 'starch' to prevent confusion with Chapter 35 products
