Enter MPF Rate (0.3464% standard) and HMF Rate (0.125% for ocean imports).

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
CIF Value ($) = 50000, Duty Rate (%) = 5, MPF Rate (%) = 0.3464, HMF Rate (%) = 0.125 = 5 input(s) provided
Calculate Total Duties & Fees
Total Duties & Fees = dutyAmount + mpf + hmf
2735.7 = $2,735.7
Calculate Landed Cost
Landed Cost = cifValueUsd + totalDuties
52735.7 = $52,735.7
Calculate Import Duty
Import Duty = cifValueUsd * (effectiveDutyRate / 100)
2500 = $2,500
Calculate MPF
MPF = min(538.40, max(29.66, cifValueUsd * (merchandiseProcessingFeePct / 100)))
173.2 = $173.2
