Hi Harry
None of the insignia shown is of US made.
Official US made authorized SSI and Tabs are Schiffli fully embroidered with an exact stitch count as per then OQMC-Heraldic Section drawings.
The Teal Blue Airborne tab was unauthorized however it was used for 77th SF Group 1955-1958. The only known use is US made, have not seen any other to date.
The letter I has not been embroidered in the Teal Blue Airborne Tab.
They are not Japanese made as Japanese embroiderers were very skilled and produced detailed high quality patches.
I believe these are modern day reproductions out of Vietnam.
Note the backing on the reverse of these samples below
