You're very close. Have this code in your .htaccess:
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
RewriteRule ^(.+)/$ /$1 [R=301,L]
RewriteRule ^profile/(.*)$ details.php?profile=$1 [L,NC,QSA]
RewriteRule ^industry/(.*)$ category.php?industry=$1 [L,NC,QSA]
RewriteRule ^page/(.+)$ index.php?page=$1 [L,NC,QSA]
# your new rule
RewriteRule ^tag/([^/]+)/([^/]+)/([^/]+)/?$ req-info.php?tag=$1&about=$2info=$3 [L,QSA,NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [R=301,L]
