how to avoidbuying Fake unlicensed beyblade

I am a beyblade seller on Ebay
Some people ask for embedded code at the bottom of the box 
I don't know how code can tell you if it's licensed genuine takara tomy beyblade or not
I contacted Takara Tomy authorized distributor in Korea and Japan
and I was told that there is no connection of showing product's Authenticity
some boxes does not have embedded code
will you buy beyblade that does not have embedded code? Or what are the factors you check before buying beyblade for it's  
Authenticity

There are some Metal Fight Beyblades known as "midfakes", with known production codes that insinuate that they were produced after the usual product runs. They usually have reduced weights and other production flaws as well. If the code is missing or unusual on the box, it's a sign to avoid unless you're fine with the midfake risk.
