HCMC Customs said that the goods include wood, scrap and others.
Many companies imported their goods in excess before the seven-day Lunar New Year holiday which began Feb. 8., causing a surge in the number of containers in January.
Many importers of scraps are "ghost" companies, established with incorrect information regarding who operates them.
Goods that are left unclaimed will be either sent back to the sender or be destroyed.
A large number of unclaimed goods can cause congestion at ports and create a shortage of empty containers, which can result in higher transportation charges.
