time of entry, this fact should be clearly stated in writing at the time 
of entry, and suspension of liquidation may be requested by the importer 
or his agent pending the furnishing of actual cost data. Actual cost 
data must be submitted as soon as accounting procedures permit. To 
insure that information used for Customs purposes is reasonably current, 
the importer shall ordinarily be required to furnish updated cost and 
assembly data at least every six months, regardless of whether he 
considers that significant changes have occurred. The 6-month period for 
the submission of updated cost or other data may be extended by the port 
director if such extension is appropriate for the type of merchandise 
involved, or because of the accounting period normally used in the 
trade, or because of other relevant circumstances.
