We have developed a supplement with a supplier in china that has their certifications in order regarding good manufacturing practices and also certified organic, although not USDA. I am unsure which other steps may be needed - i.e. legal papers etc. in order to sell at trade shows and in stores in the us (and also europe). This product is approved to sell via amazon (our ingredients are all fda approved), but i am not sure if there are special legal procedures when selling in physical stores etc. Also, if the fda bans certain ingredients - can you still sell it on amazon (just not on physical ground in the us)? Any and all insight much appreciated. Thanks.
Do an independent lab test of each item to test for heavy metal contamination, specifically cadmium, lead, mercury and arsenic. Better that you get this information in advance before someone else does it and reports it, which could lead to a very fast business demise. For reference, check the protein powder tested by Natural News and also Adya Clarity - both found to contain heavy metals and both with ingredients sourced from China. Good luck!
