Everything you need to know about privacy, local memory execution, and buyouts.
True landed cost per unit equals FOB Unit Cost + CBM-Prorated Freight per Unit + (FOB × Combined HTS & Section 301 Duty Rate) + FOB-Prorated Customs Brokerage, MPF (0.3464%), and HMF (0.125%). LandedCost Studio computes this automatically for every SKU.
Ocean container freight (FCL and LCL) is billed by volume displacement (Cubic Meters / CBM), while customs duties and MPF/HMF are billed by FOB value. Allocating freight by unit count distorts margins on bulky items.
For formal entries (over $2,500), CBP charges a Merchandise Processing Fee (MPF) of 0.3464% of FOB value (minimum $31.67, maximum $614.35) plus a 0.125% Harbor Maintenance Fee (HMF) for ocean shipments.
Yes. If a product has a 5.3% base MFN HTS duty rate and falls under a 25% Section 301 tariff list, the combined ad valorem duty applied to the FOB customs value is 30.3%.
Never. All commercial invoice parsing, CBM freight proration, and tariff waterfall calculations run 100% locally inside your browser memory with zero network uploads.
While SimplyDuty ($49/mo) and Zonos focus on per-lookup API subscriptions, LandedCost Studio is a one-time $19 lifetime buyout built specifically for multi-SKU container freight allocation and FOB-to-DDP unit margin reconciliation.
