According to N/No. 03/2018-IT, persons making inter-state taxable supplies of handicraft goods are exempted from obtaining registration if the aggregate value of such supplies does not exceed the amount of aggregate turnover above which a person becomes liable for registration u/s 22(1) read with clause (iii) of the Explanation to that section.
Further, according to Section 22(1) & N/No. 10/2019-CT, a person, who is engaged in exclusive supply of goods other than persons engaged in making intra-State supplies in the States of Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Puducherry, Sikkim, Telangana, Tripura, and Uttarakhand is exempt from obtaining registration if aggregate turnover in the FY does not exceed Rs. 40 lakhs.
In the given scenario, since handicraft goods are supplying inter-state and supplier is engaged in exclusive supply of goods, therefore the threshold limit for registration u/s 22(1) shall be Rs. 40 lakhs (assuming he is not engaged in making intra-state supplies from above-mentioned states). Hence, the person with an aggregate turnover of 35L (25L intra-state & 10L inter-state handicraft goods) is not liable for registration.
Previously as per N/No. 08/2017-IT, the threshold limit in case of inter-state supply of handicraft goods was Rs. 20 lakhs (10 lakhs in case of special category states). However, this has been superseded by N/No. 03/2018-IT. Hence, the threshold limit of 20L/10L is not relevant as of now.
