LoTariff is an online resource for people researching and bidding on vehicles from US salvage and used-car auctions. Its catalog brings together listings from Copart, IAAI, and other auction yards, with available photos, specifications, lot details, sale status, and price history. Users can search by vehicle or use a VIN and lot number to review auction and sales records.

The site also offers practical tools to help buyers assess costs and eligibility before bidding. These include a customs duty calculator, logistics estimates, and title checks, along with information about upcoming live auctions and a VIN archive. Listings cover a wide range of makes and models, from everyday cars and SUVs to luxury and electric vehicles, and may include details such as mileage, location, damage category, and sale price.

LoTariff presents customs and logistics calculations as estimates rather than official assessments. It is not affiliated with customs authorities, auction houses, or government agencies, so its tools are intended to support preliminary research and planning, not replace professional advice or official cost determinations.
