(Note:  King Arthur Flour claims the following on their packages:  "No chemicals or preservatives ever added."  

Looking at the King Arthur website, however provides the following statement:

"Enrichment has been required by the majority of the states since the 1940's in all bread and all-purpose flours. An enriched flour contains niacin, thiamin, iron and riboflavin, the B vitamins and minerals which have been determined to aid in the prevention of diseases like rickets and pellagra in children."

For some reason, King Arthur doesn't consider niacin, reduced iron, thiamin mononitrate, riboflavin, and folic acid (all listed specifically on the package) to be chemicals.  But they are!  This is certainly misleading and confusing.  Rest assured, King Arthur flour has chemicals in it...ALL flour does!)
