" The Agreement on Trade in Civil Aircraft (TCA)  was initially negotiated during the GATT 
Tokyo Round (1973 -79) and in 1995 became a plurilateral agreement under Annex 4 of the 
WTO Agreement, which requires participants to incorporate the relevant duty -free or d uty-
exempt treatment of the covered products into their respective Schedules. In other words, 
the TCA concessions are also incorporated in the WTO Members’ Schedules of 
concessions.   One challenge faced by TCA negotiators was that many products used in the  
production and maintenance of civil aircraft could also be used in the manufacture or 
maintenance of other goods (i.e. dual use).  For example, products such as tubes, pipes and 
gaskets could have many uses besides using them to manufacture a plane.  Althou gh the 
product coverage annex of the TCA includes a list of HS codes with ex -outs to be covered, 
paragraph 2 of the annex makes it clear that products shall only be accorded duty -free 
treatment or be duty -exempted " if such products are for use  in civil aircraft or ground flying 
trainers and for incorporation therein, in the course of their manufacture, repair, maintenance, 
rebuilding, modification or conversion " (emphasis added).  The Agreement also clarifies that 
three categories of products wi ll not be covered: 1) an incomplete or unfinished product, 
unless it has the essential character of a complete or finished part, component, sub -assembly 
or item of equipment of a civil aircraft or ground flying trainer (e.g. an article which has a civil 
aircraft manufacturer's part number); 2) materials in any form (e.g. sheets, plates, profile 
shapes, strips, bars, pipes, tubes or other shapes) unless they have been cut to size or shape 
and/or shaped for incorporation in a civil aircraft or a ground flying  trainer (e.g. an article 
which has a civil aircraft manufacturer's part number), and 3) raw materials and consumable 
goods. "
