Unused postage stamps, revenue stamps, check forms, banknotes, and securities such as stock or bond certificates are grouped together in trade classification because they share a common characteristic: they represent instruments of value or title rather than ordinary printed goods. Importation of banknotes and monetary instruments into the United States triggers FinCEN reporting requirements under the Bank Secrecy Act when aggregate value exceeds the statutory threshold, a compliance layer distinct from standard customs entry. Philatelic material—stamps for collectors—may be treated differently from stamps intended for postal use, and brokers often need to distinguish between the two at entry.
