Methodology

How we build estimates.

We design for planning accuracy, fast comparison, and transparent assumptions. Our tools are not customs rulings or legal advice.

Inputs first

We ask for product value, shipping mode, origin, and scenario assumptions before showing output.

Outputs are directional. Final duty, tax, and fee treatment must be verified against official sources.

We prefer official or primary references, then summarize them in plain language.

Pages are refreshed when the policy or product explanation changes enough to matter.
