The National Customs Brokers & Forwarders Association of America Inc. has asked Customs and Border Protection to revoke or modify a number of long-standing interpretative rulings that it believes have created an overly strict confidentiality standard. The NCBFAA has requested that CBP adopt a standard that requires brokers to maintain the confidentiality of an importer's "proprietary business information" which is generally defined as information which could harm the importer's competitive position if disclosed.
