Say you ship 500 synthetic men's knit swimwear from China by ocean, declared at $8.00 each (FOB). The value is $4,000.00; duty at 45.9% is $1,836.00; over $2,500 it is a formal entry, so the Merchandise Processing Fee is $34.58; the Harbor Maintenance Fee is $5.00. Duty and fees come to $1,875.58, or $3.75 per unit. The same shipment from Bangladesh comes to $1,475.58, $2.95 per unit, saving $0.80 per unit.
