Duty • New price
A tariff is a tax on imported goods, paid by the importer and usually passed along to consumers. The math is simple: tariff = price × rate, and the new price = price × (1 + rate). A 25% tariff on a $500 product adds $125, pushing it to $625. In practice, importers may absorb part of the cost, which is why this calculator lets you set the share passed to buyers.
Tariffs ripple through supply chains, so the final consumer price can rise by more or less than the headline rate depending on margins, sourcing and competition. Use this to estimate the impact on anything you buy or sell. Estimate only.
Import duty is assessed on the customs value of goods, which for most US imports is the transaction value — the price actually paid — rather than the landed cost including freight. The applicable rate comes from the goods' HTS classification, a ten-digit code that determines everything and is frequently misapplied. Two further federal charges apply on top of duty: the merchandise processing fee, a percentage of value within a floor and ceiling, and the harbor maintenance fee on sea freight. Section 301 and similar additional tariffs stack on top of the base rate rather than replacing it.

Assumptions: De minimis rules exempt low-value shipments, though the threshold has been subject to change. Country of origin, not country of shipment, determines eligibility for trade agreements and additional tariffs.

The duty rate dominates, which is why HTS classification is worth professional attention: a code carrying 3.7% instead of 25% would cut the charge to $1,665. Misclassification is assessed retroactively with penalties, so aggressive coding is a poor economy.
