Quick Reference & Frequently Asked Questions
Why should ocean and air freight be allocated by CBM or weight instead of unit count?
Freight forwarders bill ocean shipments by cubic meters (CBM) and air shipments by dimensional/gross weight. Splitting by unit count overcharges small items and hides losses on bulky SKUs.
How does Landedcoststudio calculate HTS customs duties, Section 301 tariffs, and MPF/HMF?
It multiplies each SKU's total FOB value by its base HTS duty rate plus any Section 301 surcharge, then prorates the 0.3464% CBP Merchandise Processing Fee (MPF) and 0.125% HMF.
Does Landedcoststudio upload my confidential factory invoices or supplier prices to the cloud?
No. Every packing list and commercial invoice calculation executes 100% locally in your browser RAM so your overseas factory costs and supplier details never leave your device.
How is Landedcoststudio different from Zonos ($199/mo) or Cin7 ($349/mo)?
Instead of paying $199-$349/month for heavyweight cloud ERPs, you get instant browser-based multi-SKU freight and duty allocation for a $19 one-time lifetime buyout.
