This Series Is Called "Total Imports, Free And Dutiable" Or "Imports For Consumption And Other". For July, 1953-December, 1953, Values For Under $100 Shipments (About One Tenth Of One Percent Of The Total Import Value) For Immediate Consumption Filed On Formal Entries Are Estimated From A Ten Percent Sample Of Such Shipments. From January, 1954 On, Values For $1 To $250 Formal And Informal Entry Shipments For Immediate Consumption (About One Percent Of The Total Import Value) Are Estimated From A Five Percent Sample Of Such Shipments (Prior To 1954 Informal Entries Were Excluded). Effective September, 1953 The Value Limit For Informal Entries Was Raised From $100 To $250, And From January, 1954 On, Informal Entries Have Been Included In The Import Statistics (Survey Of Current Business, Statistical Supplement 1955, Footnote To P. 104). In Anticipation Of The Longshoremen'S Strike, Certain Import Entries That Would Normally Have Been Filed In October, 1959 And Included In October Figures, Were Filed In September, And Included In That Month'S Data. The Extent Of This Increase Is Not Known (Ft900-I, December, 1959). The Total For February, 1962 Includes About $9.7 Million Of $1-99 Formal And $1-250 Informal Entry Shipments Which Are Not Included In The Data In Other Reports Such As Ft110, Ft930-I, Ft120, Im145, Etc. There Was A Dock Strike In December, 1962 And January, 1963. Figures For December, 1964 Through April, 1965 Were Influenced By Dock Strike At East Coast And Gulf Ports (See Note 4, Fi900-I, November 26, 1965). Adjustments Have Been Made In The Monthly Totals For The Period July-December, 1965 To Remove The Effect Of Abnormalities In Monthly Receipts Of Statistical Documents During That Period. See: "U.S. Exports And Imports," U.S. Department Of Commerce, November 15, 1966, P. 8, Note 2.
