The last (April 2007) update of this webpage announced that 102 NAPCS product lists had been developed or were under development pursuant to Phases I - III of the 3-country NAPCS project. Of this number, the update displayed 97 product lists, including 71 trilateral or bilateral lists designated to be final, 23 trilateral lists designated near-final, and 3 designated as US-only at that time. It also indicated that another 5 lists were still under development and not ready for display; these included list for NAICS 4885-Freight Transportation Arrangement, 4889-Other Support Activities for Transportation, 4931-Warehousing and Storage, 54142-Industrial Design Services, and 54143-Graphic Design Services. The displayed lists were edited to: standardize the table formats and the style conventions used in writing product titles and definitions; provide identical titles and definitions for products that are common to multiple lists; and extend or standardize the cross-referencing notations used to identify NAPCS products that are common to multiple NAPCS lists.
In comparison, this February 2010 update displays all 102 finalized product lists that resulted from Phases I -III of NAPCS, with 98 designated as trilateral, 3 as bilateral (US, Mexico), and one as US-only. In addition, the lists displayed in this update incorporate several more recent revisions to product lists and/or to product titles and definitions that resulted from joint-country reviews or from independent US reviews conducted during the 2007-9 period.
