In the United States, 'rebates' are widely recognized as an incentive tool that manufacturers provide directly to consumers.
Literal
US [in-において] 'rebate' [topic-は], mainly manufacturer [subject-が] consumer [to-に] directly provide incentive means [as-として] widely recognized [passive-されている].
Formal business/economics prose. において ('in,' formal locative) sets the geographic scope. リベート is the English loan 'rebate.' インセンティブ手段 combines the loan 'incentive' with 手段 ('means, tool'). ~として ('as') marks the role. 広く認識されている ('is widely recognized') is passive formal. The sentence reads like a business textbook or market analysis.
