Edwin J. Andrews discusses the fee structures for various consular services in The American Revenuer, 2008 No. 3.
In 1955, new Department of State regulations discontinued the use of stamps after the end of the fiscal year on September 30. Archival examples were retained in Washington, D.C. and the remaining stock was destroyed.
Customs Fee stamps
These stamps were used between 1887 and 1918 to pay various customs fees. They were not used to pay actual customs duties.
All stamps picture Silas Wright, U.S. Senator and New York Governor, among other positions. He has the unique distinction of winning every vote in one election but one -- his own.

Customs Baggage Inspection stamps
According to Hermann Ivester, the initial Customs Baggage Inspection stamps "were used to seal baggage that was to be carried unopened through Canada by railroad between two points in the United States, Detroit and either Buffalo, Niagara Falls, or Suspension Bridge, New York. If the baggage arrived at its destination with the stamp unbroken the customs inspector did not need to inspect it." Other Customs Baggage Inspection stamps signified that fees had been paid or no duty or taxes were due. (The American Revenuer, 2008 No 3)
Serial numbers appear on many of the Customs Baggage Inspection stamps (Ivester CB1-CB168). No plate numbers are known.
An example of a Customs Baggage stamp overprinted for use as a cigarette tax stamp can be found here.
Other Customs Fee stamps
Plate numbers are not known on Customs Cigarette stamps (Class A) (Springer TAC1-TAC27), Customs Cigar stamps (Springer TCC1-TCC58), Customs Substitute Cigar stamps (unlisted), Customs Cigar Manufactured in Bond stamps (Springer TCB1-TCB44a), or Customs House Drawback Certificate stamps (unlisted). Please report any new discoveries.
