Specific answers for teams replacing Flexport with TariffShield301 Studio.
Unlike the EU and UK (which assess duty on CIF value including shipping), US Customs and Border Protection (CBP) assesses import duties on the transaction value (FOB port of export), excluding international ocean or air freight and marine insurance.
Section 301 duties (such as 7.5%, 25%, or 50% under Chapter 99 subheadings like 9903.88.01/.03/.15) are additive to the base Most Favored Nation (MFN) Column 1 duty rate. A backpack with a 17.6% base MFN rate and a 25% Section 301 tariff faces a 42.6% total duty rate before CBP fees.
Formal US customs entries (> $2,500 value) incur an ad valorem Merchandise Processing Fee (MPF) of 0.3464% of FOB value (subject to a $31.67 minimum and $614.35 maximum per entry) plus a 0.125% Harbor Maintenance Fee (HMF) for ocean vessel arrivals.
Because the tariff is multiplied against the FOB price. Lowering a $10.00 FOB price by 8% ($0.80) saves $0.80 on the product AND saves $0.24 on a 30% stacked duty—delivering $1.04 in total landed cost reduction.
If your landed cost increases by $2.00/unit and you raise your Amazon retail price by $2.00, Amazon's 15% referral fee takes $0.30 of that increase. You must gross up the pass-through amount by dividing by (1 - referral_fee_rate), or $2.00 / 0.85 = $2.35.
Never. All tariff stacking calculations, CBP fee audits, and CSV exports run 100% locally in your browser RAM.
