Is Vortex made in China?
Vortex does not name a country of manufacture on its website, so check the country-of-origin marking on the binocular or its box for the model you are buying.
By Parbat, updated

Headquarters, design, testing and warranty service do not establish where a binocular is made.
Check the country label and ask the maker for written confirmation of the model number and production version before choosing on origin. A claim about a riflescope or another product cannot establish binocular manufacture. See the distinction between US branding, assembly and manufacture.
Is Vortex made in China? Frequently Asked Questions
Where are Vortex products made?
Vortex does not name a country of manufacture on its website. Its warranty page says its products are designed, engineered, pre-inspected and serviced in its own facility, and the company is headquartered in Barneveld, Wisconsin. Neither statement says where a binocular is built. Check the country-of-origin marking on the binocular or its box for the exact model you are buying.
How can I find out where a specific Vortex model is made?
Read the country-of-origin marking on the binocular or its packaging. If it is not shown in the listing, ask the seller before you buy, or call Vortex on 1-800-4VORTEX, the number on its warranty page, with the model number.
What does the Vortex VIP warranty cover?
Vortex calls it an unlimited, unconditional lifetime warranty: it repairs or replaces a damaged or defective product at no charge, whatever caused the damage and wherever you bought it. It does not cover loss, theft, deliberate damage or cosmetic damage that does not affect performance (Vortex VIP warranty).
