The European Commission's explanatory notes on how to classify goods in these CN codes. They are not legally binding but customs authorities follow them; they complement the HS Explanatory Notes of the World Customs Organization.
For the definition of the prefix ‘poly’, in the sense of this heading, see subheading note 1(a)(1) to this chapter.
General
The HS Explanatory Note to Chapter 39, General, ‘Combinations of plastics and materials other than textiles’, point (d), applies, mutatis mutandis, to combinations of carbon fibres and plastics.
Note 4
Calculation of mass ratios of monomer units in copolymers:
The mass ratios of the respective monomer units in copolymer chains are calculated based on the molecular structure of the copolymer (not the starting materials), taking into account the formation reaction of the polymer. When applicable, the atom linking two adjacent monomer units is attributed to the monomer unit from which the atom originates.
The following examples illustrate the calculation of the monomer unit content in copolymers:
Note 6
The term ‘solutions’, used both in this note and in note 4 to Chapter 32, does not apply to colloidal solutions.
For the definition of the term ‘primary forms’, see note 6 to this chapter and the HS General Explanatory Note to this chapter, ‘Primary Forms’.
