Hi,
Yes, there are alot of risks with ordering from China / India or any other country.
First issue, all depending on which country you are from each country has "Customs High Risk" controll units. For example Sweden, all packages sent from example, Colombia, Ecuador, China, India etc. are "High Risk Packages" because of high exportation of Cocaine, Heroin, P2nP, BMK-Oil etc. so there will be extra controlls of paper work, containers and more.
Secon issue, legitimacy, without visiting the actuall company or being recommended by a legit source you won't know the legitimacy of the supplier or it's supplies, so it's a high risk gamble. To resolve this issue you can get in contact with as many suppliers as possible for example China, get yourself invited for an "audit" and test their product on site and start a relationship on site.
Third issue, identity, too import illicit materials you want to work under a pseudonym and know how shells companies work and how to set them up, also the supplier that you have a relation with needs to know how your shell company works so they can adapts their products under "pseudonyms" as well to not raise suspicion.
These are just a few pointers getting started and for you to do research about.
Best Regards
