In a recent article for American Shipper, Michael Cerny, chief legal officer for Charter Brokerage, explains how filing for a duty refund with U.S. Customs and Border Protection (CBP) has become more efficient as filers become more familiar with the types of duty drawback and the new requirements for filing claims electronically. “We are seeing drawback for commodities/products where we did not see it before,” said Cerny. “No question that during that first year, issues cropped up with particular validations or data processing that resulted in CBP updating and fixing bugs and filers addressing issues in their own software programs.”.
