The nonlegal statistical elements that appear in the HTS are formulated by an
interagency committee authorized under section 484(f) of the Tariff Act of 1930 (19 U.S.C.
1484(f)) and chaired by the Commission. Information about the operation of this Committee
and procedures for requesting statistical changes in the HTS or in the export schedule,
Schedule B, are set forth later in this preface. Other nonlegal elements are included for the
convenience of the user. For example, footnotes (which may elaborate on a provision or refer
to another HTS provision) are merely informational, their presence or absence has no legal
effect, and the language contained in footnotes has no effect on the legal text or its
interpretation. Compiler’s notes are also added to provide information to users of the HTS,
especially where provisions have expired or may not have been updated. A list of legal
instruments and nonlegal actions affecting each HTS edition is set forth in the preface and,
together with the change record and chapters 98 and 99, should be consulted to locate any
actions that may apply to specific goods. (See changes pertaining to the current edition,
below.)
