Supply without consideration: principal-agent goods transfers treated as taxable supplies triggering registration and tax obligations under GST. Para 3 of Schedule I treats transfers of goods between principal and agent without consideration as supply, so such goods transactions are taxable even without consideration; the entry applies only to goods (not services). Agents making taxable supplies on behalf of principals face mandatory GST registration irrespective of turnover when the principal is a taxable person, while supplies on behalf of non taxable principals (such as certain agriculturists) do not trigger compulsory registration under the principal agent clause; reverse charge and del credere scenarios affect value and registration outcomes.
