SinoSource analysts verify your supplier, negotiate FOB pricing, coordinate QC, and keep you updated monthly, so you import with confidence, not guesswork.
See subscription plansUnit price is the number suppliers compete on and the one that explains the least about whether an order makes money. The scenario builder works from your own assumptions so you can see which of them the margin actually depends on.
Ocean rates move on a scale that quietly rewrites a business case. Model the rate you were quoted and a materially worse one, because the second number tells you how much room the product really has.
The headline tariff is a floor. Anti-dumping and countervailing measures attach to specific code and origin combinations and can exceed the base rate several times over.
Import VAT is usually recoverable, so it rarely changes profitability, but it is paid at the border and reclaimed later. On a large order that gap is a real financing cost even though it never appears in the margin.
Testing, certification, customs brokerage, inland transport, warehousing, returns and the share of stock that never sells. These sit outside the supplier quotation, which is exactly why they are the ones that get left out.
No. You enter a verified duty rate you have already confirmed for your classification, origin and import date. The tool models the consequences of that rate rather than sourcing it, because a rate is only correct for a specific combination of code, origin and date.
A single scenario tells you what happens if every assumption holds, which is the least likely outcome. Comparing a base case against a worse freight rate or a weaker exchange rate shows which assumption the margin is genuinely exposed to.
That depends on your channel, your return rate and how much stock you carry, so no general number is useful. The more practical question is how far an assumption can move before the order stops making sense.
The scenario runs from the figures you enter in the form. Nothing is published, and the estimator is free to use.
