This has not been my experience. I've owned 6 Arizer vaporizers and not one of their boxes has said anything about where they are manufactured. This includes the three boxes for the Solo II, Air II, and ArGo which I am looking at as I type this.
The only mention of geographical locations are on the bottom side of the box and on the back page of the Owner's Manual. On the bottom side of the box it says:
Designed in Canada
and:
Arizer, the Arizer logos, and Solo II are trademarks or registered trademarks of Arizer in Canada, USA, Europe, Asia and other jurisdictions
and:
Arizer. 55 Northfield Drive East, Unit 391 Waterloo, ON, N2K 3T6
On the back page of the Owner's Manual it says:
©2017 Arizer, Waterloo, ON Canada. All rights reserved. Patents Pending. Designed in Canada, parts sourced worldwide.
Arizer, the arizer logos, and Solo II are trademarks or registered trademarks of Arizer in Canada, USA, Europe, Asia and other jurisdictions
There is no other mention of any other place anywhere – neither on the other 5 sides of the box, nor on the other pages of the Owner's Manual.
