Goods
which

be
included
in
two
or
more
of
the
headings
of
this
Chapter
are
to
be
classified
in
that
one
of
those
headings
which
occurs
last
in
numerical
order.
4.
In
headings
2904
to
2906,
2908
to
2911 and 2913
to
2920,
any
reference
to
halogenated, sulphonated,
nitrated
or
nitrosated
derivatives
includes
a
reference
to
compound
derivatives,
such
as
sulphohalogenated,
nitrohalogenated,
nitrosulphonated
or
nitrosulphohalogenated
derivatives.
Nitro or nitroso groups are not to be taken as "nitrogen-functions" for the purposes of heading 2929.
For the purposes of headings 2911, 2912, 2914, 2918 and 2922, ―oxygen function‖, the characteristic organic oxygen-containing group of those respective headings, is restricted to the oxygen-functions referred to in headings 2905 to 2920.
old[For
the
purposes
of
headings
2911,
2912,
2914,
2918
and
2922,
"oxygen-function"
is
to
be
restricted
to
the
functions
(the
characteristic
organic
oxygen-containing
groups)
referred
to
in
headings
2905
to
2920.]
5. (A) The esters of acid-function organic compounds of sub-Chapters
I
to
VII
with
organic
compounds
of
these
sub-Chapters
are
to
be
classified
with
that
compound
which
is
classified
in
the
heading
which
occurs
last
in
numerical
order
in
these
sub-Chapters.
(B) Esters
of
ethyl
alcohol
with
acid-function
organic
compounds
of
sub-Chapters
I
to
VII
are
to
be
classified
in
the
same
heading
as
the
corresponding
acid-function
compounds.
(C) Subject
to
Note
1
to
Section
VI
and
Note
2
to
Chapter
28:
(1) Inorganic
salts
of
organic
compounds
such
as
acid-,
phenol-
or
enol-function compounds or organic bases, of sub-Chapters I to X or heading
2942, are to be classified in the heading appropriate to the organic
compound;
(2) Salts
formed
between
organic
compounds
of
sub-Chapters
I
to
X
or
heading
2942
are
to
be
classified
in
the
heading
appropriate
to
the
base
or
to
the
acid
(including
phenol-
or enol-function
compounds)
from
which
they
are
formed,
whichever
occurs
last
in
numerical
order
in
the
Chapter.
(3) co-ordination compounds, other than products classifiable in
Sub-Chapter XI or heading 2941, are to be classified in the heading which occurs last in numerical
order in Chapter 29, among those appropriate to the fragments formed by "cleaving" of all
metal bonds, other than metal-carbon bonds.
(D) Metal
alcoholates
are
to
be
classified
in
the
same
heading
as
the
corresponding
alcohols
except
in
the
case
of
ethanol
(heading
2905).
(E) Halides
of
carboxylic
acids
are
to
be
classified
in
the
same
heading
as
the
corresponding
acids.
6.
The
compounds
of
headings
2930
and
2931
are
organic
compounds
the
molecules
of
which
contain,
in
addition
to
atoms
of
hydrogen,
oxygen
or
nitrogen,
atoms
of
other
non-metals
or
of
metals
(such
as sulphur, arsenic or
lead)
directly
linked
to
carbon
atoms.
Heading
2930
(organo-sulphur
compounds)
and
heading
2931
(other organo-inorganic
compounds)
do
not
include
sulphonated
or
halogenated
derivatives
(including
compound
derivatives)
which,
apart
from
hydrogen,
oxygen
and
nitrogen,
only
have
directly
linked
to
carbon
the
atoms
of
sulphur
or
of
a
halogen
which
give
them
their
nature
of
sulphonated
or
halogenated
derivatives
(or
compound
derivatives).
7.
Headings
2932,
2933
and
2934
do
not
include epoxides
with
a
three-membered
ring,
ketone
peroxides,
cyclic
polymers
of
aldehydes
or
of
thioaldehydes, anhydrides of
polybasic
carboxylic
acids,
cyclic
esters
of
polyhydric
alcohols
or
phenols
with
polybasic
acids,
or
imides
of
polybasic
acids.
These
provisions
apply
only
when
the
ring-position
hetero-atoms
are
those
resulting
solely
from
the
cyclising
function
or
functions
here
listed.
8.
For
the
purposes
of
heading
2937:
(a)
the
term
"hormones"
includes
hormone-releasing
or
hormone-stimulating
factors,
hormone
inhibitors
and
hormone
antagonists
(anti-hormones);
(b)
the
expression
"used
primarily
as
hormones"
applies
not
only
to
hormone
derivatives
and
structural
analogues
used
primarily
for
their
hormonal
effect,
but
also
to
those
derivatives
and
structural
analogues
used
primarily
as
intermediates
in
the
synthesis
of
products
of
this
heading.
SUB-HEADING NOTES
1.Within any one heading of this Chapter,
derivatives of a chemical compound (or group of chemical compounds) are to be
classified in the same sub-heading as that compound (or group of compounds)
provided that they are not more specially covered by any other sub-heading and
that there is no residual sub-heading named "other" in the series of subheadings
concerned
2. Note 3 to this Chapter shall not be applicable to the sub-headings of this
Chapter.
