Non Rectangular Rubber Sheet

Within the Chapter notes for 4008219000 it states:
“9. In headings 4001, 4002, 4003, 4005 and 4008, the expressions ‘plates’, ‘sheets’ and ‘strip’ apply only to plates, sheets and strip and to blocks of regular geometric shape, uncut or simply cut to rectangular (including square) shape, whether or not having the character of articles and whether or not printed or otherwise surface-worked, but not otherwise cut to shape or further worked.”

Where the geometric shape is oval or oblate, would this code still apply? In all other regards, this appears to be the most appropriate code I could apply to an item of this nature.
