Complicated cyclic compounds are more complex:
These compounds are produced by the intensification of incompatible pentagon or hexahedral groups, with other carboxylic rings. The following groups are mentioned:
A) Comaron.
B.
C - Oxantin (Zanthini).
D - Endol.
E - Quinoline and Isinquinoline.
And - acridine.
G) Benzoethiophene (Theo naphthene).
H. Andazole.
I-bisimidazole.
J - Technicians.
K-Phenoxyazine.
L-Nizoxazole.
M - Carbazole.
N-kinazoline.
O Benzothiazole.
For the purposes of heading 29.32 to 29.34, for vehicles containing more than one uncoordinated ring, if only one of the non-harmonized rings is specifically named in one of the subheadings of heading 29.32 to 29.34, that compound shall enter Under that sub-item. However, if two or more of the incompatible rings are specifically named at the sub-item level, the compound must enter the specified item that comes too late in the numerical order.
