U.S. customs duties rose to a record $29.6 billion in July, extending a four-month streak of elevated collections since new import levies took effect in March. July’s intake surpassed June’s $26.6 billion and May’s $22.2 billion, bringing cumulative tariff and related excise revenue to about $78 billion over the past three months, according to preliminary federal data. The jump in receipts reflects both higher effective rates and a broader range of goods subject to duties. Average applied tariffs reached 9 percent of all imports in June—roughly quadruple the pre-Trump norm—even though tariffed products now account for a smaller share of total import volumes. Analysts note a shift in the composition of revenue: June figures show a decline in collections from Chinese goods and an increase from imports originating elsewhere, underscoring the widening scope of the Biden administration’s ‘America First’ trade strategy. Officials say the duties have become a stable and growing source of federal income, while economists continue to debate their long-term impact on prices and trade flows.
