A typo in trade rules means the Census Bureau must fix its own fix

The Census Bureau published a rule about how companies must report goods moving through the US. It turns out the rule itself contained a mistake in a list of legal references. The agency must now issue a correction to its own correction.

This document is a correction to a previous correction. It shows how complex and error-prone the process of updating trade regulations can be. Even small errors can require official federal register notices to fix.
