Yes this interest is taxable as per section 15(Value of supply provision).
Same HSN code and rate is applicable against the supply of which interest is received. For example:- You sold a bike of Rs. 128000/- with HSN code 4444(say) having tax rate 28%(say). Now you dont receive the payment on time so you charge interest @ 18%(Rs 100000*18%=18000) by raising debit note. Debit note will contain same HSN and rate i.e. 4444 and 28% respectively. Amount will be 18000+28%of18000=23040/-
