I want to send a box of items purchased from Wal-mart. The items are Glusomine & Kondrotin for knee problems, Multiple vitamins (mature), and Omega 3 tablets. Are these items allowed to be shipped to china and pass customs without a problem? If they do not pass customs, what happens to my shippment of items? The box size is approximately 12" x 12" x 7, and around 13 pounds in weight. Value of the items shipped will be around $220 US Dollars. I am aware that I need to fill out a form 2976-A.
