Stop overpaying for bloated legacy cloud software.
Importers pricing 20–50 container SKUs per season shouldn't pay $588/year for a cloud duty widget.
Basic duty calculators only check one HS code at a time and fail to split a $4,200 container bill across 8 mixed SKUs by CBM volume.
Uploading commercial invoices to cloud platforms exposes your confidential factory unit costs and supplier relationships.

Specific answers for teams replacing SimplyDuty with LandedCost Studio.
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.
