How we build estimates.
Import Cost IQ designs for planning accuracy, fast comparison, and transparent assumptions. Our tools are not customs rulings or legal advice. Here is exactly how they work.
How Calculators Work
Each calculator takes seller-provided inputs (product cost, shipping mode, quantity, duty rate assumptions, etc.) and applies a transparent formula to produce an estimated output. The formula and assumptions are shown on each calculator page so you can verify and adjust.
What Inputs Are Used
Calculators use only the inputs you provide: product value, freight cost, insurance, duty rate, customs fees, brokerage, quantity, and similar planning parameters. We do not pull real-time duty rates, freight quotes, or customs data from external APIs unless explicitly noted.
What Formulas Are Used
Standard cost-accounting formulas: Landed Cost = Product + Freight + Insurance + Duty + Fees. Duty = Customs Value x Duty Rate. Margin = (Price - Cost) / Price. Each calculator page displays the exact formula used so you can replicate and verify.
What Outputs Mean
Outputs are planning estimates, not guaranteed costs. They help you compare scenarios, set initial pricing, and identify cost drivers before placing orders. They should not be used as final customs entry values or for accounting purposes.
What Is Not Guaranteed
Actual duty rates depend on correct HS classification, current trade policy, and CBP determination. Actual freight costs depend on carrier, route, season, fuel surcharges, and cargo characteristics. Brokerage and customs fees vary by provider and shipment specifics. All outputs are directional.
Why Duty Rates Depend on HTS Classification
The US Harmonized Tariff Schedule assigns different duty rates to different product categories. A single digit in the HS code can mean the difference between 0% and 25% duty. Correct classification requires product expertise — we recommend consulting a licensed customs broker.
Why Shipping Cost Is Only an Estimate
Published freight rates change weekly based on capacity, fuel costs, seasonal demand, and route conditions. Our calculators use planning rates; your actual freight cost will come from your carrier or freight forwarder's quote at the time of booking.
How Often Pages Are Reviewed
Calculator pages and guides are reviewed at least quarterly, or sooner when significant policy or market changes occur. The last-reviewed date is shown on each page. Intelligence briefs include their publication date and source notes.
Planning-Only Disclaimer
