The London Irish rising star was a surprise selection by Robinson, especially as he has previously played for Wales’ Under-20 team.
That, the WRU argues, should prevent him from representing any other nation at senior level as Wales do not field an A team, effectively making the Under-20s their second-string team.
"The Wales Under-20 team is currently the WRU-nominated side for qualification, which means that players who represent Wales at this level in certain games are then solely qualified for Welsh senior honours," the Welsh insisted in a statement.
"All Welsh players who represent Wales at Under-20 level against nations which also designate their Under-20 teams as their qualification sides are informed that they will then be registered as liable for Wales selection only at senior level.
"Shingler played for Wales Under-20's against France in 2011, before which he was specifically informed, as were his fellow squad members, that the match would confirm their sole qualification as potential Wales senior international candidates.
"Shingler was told by the Under-20 team management that, if he played in the game, he would become a Wales qualified player and therefore ineligible for selection for any other nation."
However Shingler, whose mother is from Dumfries, told the SRU that he is still eligible for selection by another country.
And the SRU have pointed to a precedent set by former Wales Under-20 players Matthew Jarvis and James Loxton who are now playing for Connacht and have been Irish-qualified.
"Steven confirmed that he declined to sign a declaration he was committed solely to Wales," said the SRU.
"Steven has informed us that he made it clear that he wished to leave open his international eligibility as he was also eligible to represent Scotland and England as well as Wales.
"Scottish Rugby believe we have acted in good faith in this matter and have also taken cognisance of an IRB ruling last year concerning two players who played for Wales under-20 against France under-20 in 2010 who now play for Connacht and are eligible for Ireland.
"We are liaising with the IRB on this matter."
