The forward has not played for the club since the turn of year due to international duty with South Korea but is back and available earlier than expected.
South Korea lost 2-0 to Jordan in Tuesday's semi-final meaning Hwang is ready to face Brentford this weekend.
The 11-goal joint top scorer could also been joined by Boubacar Traore, who is back from the Africa Cup of Nations after Mali's elimination.
Manager Gary O'Neil said on Friday: "Both are fit and available to start. There will be some decisions to make. I'm disappointed for Channy as I know he was extremely keen to win the Asia Cup for his country.
"We're disappointed for him he can't quite go all the way but we get him back one game earlier than expected and he gives us a fantastic option. Having Channy back around the group gave everyone a lift this morning."
Wolves face Brentford for the fourth time in 45 days having beaten the Bees 4-1 in the Premier League in December and overcome them in an FA Cup third-round replay last month.
