Amendment of Import General Manifest permitted with fee when no fraudulent intent; major changes face scrutiny and possible adjudication. Amendment of the Import General Manifest (IGM) is permitted on payment of prescribed fees where there is no fraudulent intention. The Board divides amendments into Major Amendments (e.g., adding entries, changing quantities, bill of lading date, importer name, commodity description, cargo/baggage status) and Minor Amendments (e.g., address corrections, spelling, unit conversions, limited container-number edits, marks, ports, package details where weight unchanged). Major amendments may require adjudication if fraud or significant revenue impact is suspected; post-arrival amendments are examined for veracity and subject to prompt approval timelines.
