How to Use the Auto Parts Import vs Domestic Cost Calculator
Parts listed on overseas marketplaces often look far cheaper than the same item from a local shop, but once you add customs duty and international shipping, the gap can shrink or disappear. This calculator takes the import unit price, duty rate, and shipping cost, works out the true landed cost, and compares it against the domestic price for the same part.
Duty rates for auto parts depend on the item's Harmonized Tariff Schedule (HTS) code, and most common parts fall in the 0-2.5% range for personal imports into the U.S. Under the de minimis rule, shipments valued under $800 are generally duty-free, though this threshold and the rules around it can change, so it's worth confirming current CBP guidance for higher-value or restricted items.
Price isn't the only factor. Imported parts typically take one to three weeks to arrive, and returns or warranty claims are harder to process across borders than with a local supplier. Always check the OEM part number against your vehicle before ordering, and if the savings are marginal, buying domestically for easier returns and support may be the smarter choice.
