Use of adjective "made" as adverb

parts-of-speech

It's a compound adjective (not an adverb). There is a huge class of these expressions with the format noun plus past participle, such as "wind-powered", "sun-dried", "middle-aged", "German-made", "strawberry-flavoured"...

Often you use a hyphen in these expressions but it's not essential. The APA style guide says to only use a hyphen to avoid ambiguity or if the compound adjective is used before the noun it modifies, so "client-centred counselling" but "the counselling was client centred".
