(b) cutting to shape does not affect the classification of glass in sheets;

(c) the expression “absorbent, reflecting or non-reflecting layer” means a microscopically thin coating of metal or of a chemical compound (for example, metal oxide) which absorbs, for example, infra-red light or improves the reflecting qualities of the glass while still allowing it to retain a degree of transparency or translucency; or which prevents light from being reflected on the surface of the glass.

3. The products referred to in heading 70.06 remain classified in that heading whether or not they have the character of articles.

4. For the purposes of heading 70.19, the expression “glass wool” means:

(a) Mineral wools with a silica (SiO2) content not less than 60% by weight;

(b) Mineral wools with a silica (SiO2) content less than 60% but with an alkaline oxide (K2O or Na2O) content exceeding 5% by weight or a boric oxide (B2O3) content exceeding 2% by weight.
