On July 14, 2009, the Bureau of Customs and Border Protection (CBP) issued correcting amendments to the interim final rule entitled "Importer Security Filing and Additional Carrier Requirements" originally published in the Federal Register on November 25, 2008.
Pursuant to the interim final rule, commonly known as the 10+2 rule, an Importer Security Filing (ISF) must be filed for cargo arriving into a U.S. port generally no later than 24 hours before the cargo is laden aboard a vessel at a foreign port.
The new correcting amendment added a new paragraph (b)(5) to 19 C.F.R. §149.2 to clarify that ISFs for shipments intended to be transported in-bond as immediate exportations (I&Es) or transportation and exportations (T&Es) must be transmitted no later than 24 hours before the cargo is laden aboard a vessel that is destined to the U.S.
With respect to the obligation to amend the ISF, CBP specified that the ISF must be updated if there is a change to any of the ISF data elements before the goods enter the boundaries of the first port of arrival in the U.S. Amendments to the ISF are accepted at any time after the goods arrive in a U.S. port.
