Inquiry regarding Amazon FBA LCL shipment (Infant/Children's clothing)

Hello. I have a small sample shipment for Amazon FBA. The cargo type is infant/children's clothing, the quantity is 4 CTNS, the weight is approximately 12kg × 4 (around 50kg total), and the total volume is about 0.24 CBM. I would like to inquire about import (IOR required), customs clearance, and FBA-related services.
