Reuse of Food Grade Tins
Different types of tins are intended for storing different types of foods (dry crackers are very different from cheeses that contain some moisture).  And as mentioned previously, linings can chip when the tin is being cleaned.  Food grade does not mean that they are reusable - I'd contact the source and ask them.  Usually the I&amp;I (industrial and institutional) market has sturdier packaging than home use.  If the I&amp;I is not to be reused, I'd really doubt yours is suitable, especially for moist products.
