USA importer by sea ocean shipment ?? ISF??    
CBP will begin the next stage on full enforcement for the filing of theImporter Security Filing (ISF) beginning on May 14, 2015. On that date,all penalty actions for ISF violations will be initiated in each of the localCustoms’ Ports and copies will not be sent to CBP HQ for review and approval.Also, the local Ports will not be required to issue 3 strikes before issu ing penalties for liquidated damages.
The Ports will still have flexibility in their processes that were allowed duringthe previous stage of enforcement. For example, here in Los Angeles, CBP still plans to place holds on Cargo that does not have an ISF matched to it on themanifest within 4 days of arrival. However, Los Angeles CBP will issue penalties to continually late ISF filers. Other Ports may still issue warnings while some may just take immediate penalty action.
