GST classification of inks clarified after omission and correction, confirming taxable treatment under amendment GST treatment of specified goods under Schedule 3 is taxable until 21-09-2025; the entry for printing and other inks was omitted by notification no. 43/2017 (w.e.f. 15-11-2017), replacing earlier wording that excluded fountain pen and ball pen inks, and a departmental correction (F. No. 354/117/2017-TRU dated 27-7-2017) corrects the prior parenthetical reference.
