About ShipCost Lab

ShipCost Lab is a portfolio of free, single-purpose decision tools for cross-border e-commerce sellers. Each tool answers exactly one shipping-cost question — what duty rate applies, which weight the carrier bills, which Incoterm fits the route, what a customs broker typically charges — and shows the source behind every number it outputs.

Who runs it

The site is built and maintained by an independent operator (the legal identity, tax ID, and contact address are published in the legal notice). It is not a freight forwarder, a customs brokerage, or a software vendor with a sales team. There is no login, no lead capture, and no “talk to sales” funnel behind any calculator.

One operator, one tool family

Every calculator on a *.shipcostlab.com subdomain — 21 at the last build — belongs to this same family: built and operated by the same person, sharing one methodology, one brand, and one data-verification calendar. The full, current directory lives on the ShipCost Lab homepage (it is generated from the live deployments at every build, so it never lists a tool that is not actually up). Nothing under this domain is third-party, white-labeled, or sponsored by a carrier or broker.

Why it exists

Most landed-cost answers online sit inside tools designed to sell freight or capture leads, which makes the numbers hard to trust and the assumptions impossible to inspect. ShipCost Lab takes the opposite stance: deterministic calculations, inputs you can see, statutory and tariff sources cited next to each result, and a published revision date for every dataset.

What it is not

These tools produce estimates from public sources — they are not binding customs rulings, tax advice, or a substitute for a licensed customs broker. Where a calculation depends on a fast-moving regulation, the tool names the regulation and links the official source so you can verify the current state before committing money to it. How the data is gathered and refreshed is documented on the methodology page.

Questions, corrections, or a broken-number report: [email protected]. Corrections to a published rate or rule are treated as bugs and fixed in the next data refresh.
