India does not necessarily have the same hygenic standards we enjoy here.
For example, it is recommended that visitors from my office bring a fresh in-wrapper toothbrush for each day they are in New Delhi. Bottled water to brush and rinse.
It is quite common to see people (usually the very poor) defecating in the street. And some do not understand the proper application of toilet paper.
That being said, it would be difficult for me to simply assume MIM parts are made in India without confirmation from a manufacturer. When it comes to simple operations like creating metal injection molded parts, india isn’t necessarily the workshop of the world anymore. They are more expensive now than in times past.
