GST on soybean oil cake treated as reduced rate taxable supply for a limited period; amendment clarifies prior feed exclusions. Imposition of GST @ 5% on oil cake and other solid residues resulting from the extraction of soybean oil is specified in Schedule 1, applicable up to the stated cut off date; an amendment replaced earlier text that had explicitly excluded various categories of animal and poultry feed and related materials, thereby clarifying the Schedule classification for these residues.
