Who did the sugar act mainly affect?

I think the sugar act mainly affected the American colonies.

To Reduce the rate of tax on molasses from six pence to three pence per gallon - but ensured the new tax could be collected by increased British military presence and controlsEstablish British admiralty courts for tax violators where a judge decided the outcome rather than in colonial courtsRegulate the trade by effectively closing the legal trade to non-British suppliers. The Act was designed to stop trade between New England and the Middle colonies with French, Dutch, and Spanish in the West IndiesProvide for the seizure of cargoes violating the new rulesReduce the practice of smuggling bribery, intimidation and corruption in the colonies which were used to avoid paying taxesThe act taxed more foreign goods including wines, coffee, cambric and printed calicoTimber and iron were also included in the products that could be traded only with England
