Yes, but only for carrier and bill of lading data that was transmitted with an entry that has not had a "hold" placed on it because of CBP concerns over compliance with the BTA. CBP will also allow some minor changes to occur for BTA covered tariff rate quota merchandise. All other changes will require the original entry to be cancelled and a new entry filed. This may also require new PN information depending upon the nature of the change being made. CBP will track the workload generated by this requirement and re-examine the procedure if necessary.
