***Concordance between the Schedule B and Harmonized System***





        In 1989, the United States changed its system for

collecting export  (and import) data.  Prior to that year, the

export data were collected according to the Schedule B

classification, whereas beginning in 1989 the data were

collected according to the Harmonized System (HS).  The

file SCH_B_HS.ASC contains a cross-reference between the

Schedule B codes for 1987, and the HS codes proposed at that

time.  The actual conversion from the Schedule B codes and

the HS codes occurred in 1989, so this file can be used to

obtain the linkage between a 1987 or 1988 Schedule B code,

and the corresponding HS code in 1989.  (HS codes that were

introduced in years later than 1989 would not be reflected

in this cross-reference).
