Quick Reference
Our Verification Process
AI-Powered Research
We use AI to analyze brand websites, product pages, and public manufacturing claims to determine origin status.
Classification
Products are classified based on FTC guidelines for "Made in USA" and "Assembled in USA" claims.
Continuous Updates
We regularly re-verify products as brands update their manufacturing practices and claims.
A note on accuracy
Our verification is AI-powered and based on publicly available information from brands. While we strive for accuracy and get it right most of the time, we can't guarantee that every brand's claims are truthful or that our classifications are 100% correct.
If you spot an error or have updated information about a product's origin, please let us know. We review all submissions and update our database accordingly.
Common Questions
What does "Made in USA" mean according to the FTC?
The FTC requires that products labeled "Made in USA" be "all or virtually all" made in the United States. This means final assembly, significant processing, and the vast majority of components must be domestic.
Why include "Assembled in USA" products?
Many quality products are substantially assembled in American facilities using some imported components. These products still support American jobs, meet domestic quality standards, and represent a meaningful commitment to US manufacturing.
How accurate is your verification?
We use AI to research brand claims and classify products, which means we're right most of the time but not perfect. We rely on what brands publicly state about their manufacturing — we can't independently verify every factory or supply chain. If you find an error, let us know and we'll fix it.
Can brands pay for better placement?
No. Our verification is editorially independent. We earn revenue through affiliate partnerships, but brands cannot pay for placement or favorable classification.
What if I find an error?
We want to get it right. If you know a product is misclassified or a brand has changed where they manufacture, contact us with details and we'll investigate and update our listings.
