HS heading: 3917

1Throughout the nomenclature, the expression plastics means those materials of headings 3901 to 3914 which are or have been capable, either at the moment of polymerisation or at some subsequent stage, of being formed under external influence (usually heat and pressure, if necessary with a solvent or plasticiser) by moulding, casting, extruding, rolling or other process into shapes which are retained on the removal of the external influence.Throughout the nomenclature, any reference to plastics also includes vulcanised fibre. The expression, however, does not apply to materials regarded as textile materials of Section XI.
