SECTION B — PERFORMING OPERATIONS
  
SHAPING
 B29
WORKING OF PLASTICS; WORKING OF SUBSTANCES IN A PLASTIC STATE, IN GENERAL; WORKING OF SUBSTANCES NOT OTHERWISE PROVIDED FOR (see Section C, particularly C08, for chemical matters; shaping clay or other ceramic compositions, slag, or mixtures containing cementitious material B28B)
 B29

Note(s)

  1. For the purpose of this class, "plastics" means macromolecular compounds or compositions based thereon.
  2. A product is not classified here unless it results from a process which is itself classified in this class.
