Courier import restrictions: specified categories require additional clearances, limiting fast-track customs clearance under manual mode. Import via courier is generally allowed but subject to exclusions for goods needing extra statutory or expert clearances or special handling: precious and semi-precious cargo, animals and plants, perishables, publications with incorrect boundaries, precious metals and stones, goods under export promotion schemes including EOU, and individual packages over the 70 kg weight limit under manual mode. Electronic mode removes the 70 kg restriction and permits EOU scheme clearance, while exclusions persist where additional testing, referrals, or terminal capacity constraints make fast-track clearance impracticable.
