(b) Articles of Chapter 71 (for example, imitation
jewellery);
(c) Optical fibre cables of heading 85.44,
electrical insulators (heading 85.46) or
fittings of insulating material of heading
85.47;
(d) Optical fibres, optically worked optical
elements, hypodermic syringes, artificial
eyes, thermometers, barometers, hydrometers or
other articles of Chapter 90;
(e) Lamps or lighting fittings, illuminated signs,
illuminated name-plates or the like, having a
permanently fixed light source, or parts

2. For the purposes of headings 70.03, 70.04 and 70.05:
(a) glass is not regarded as "worked" by reason of
any process it has undergone before annealing;
(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 7006.00.00 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.
Mineral wools which do not comply with the
above specifications fall in heading 68.06.
5. Throughout the Nomenclature, the expression "glass"
includes fused quartz and other fused silica.
