Actually sir, the Berry Adm is misunderstood by most, for example in your question you brought up "the thread", but this type of thing is covered by the Berry adm, the following is from the Gov Web Site:
J.The Berry Amendment does not apply to acquisitions of end products incidentally incorporating cotton, other natural fibers, or wool, for which the estimated value of the cotton, other natural fibers, or wool- A.Is not more than 10 percent of the total price of the end product;
As long at the thread in your example wasn't more than 10% of the total price, no problem. The Berry Adm was an Acknowledgment by the Fed, that as long at they are spending American Tax Dollars on goods, those goods should be purchased from Americans paying those taxes. I think it's a good start, one of the few laws the fed has come up with in a long time, I support. In fact, I'd make it even more restrictive if I had a chance. American's need to look out for ourselves, God knows, no one else the world would look up for us.
