Tariffs Reset in April, Forcing Distributors to Navigate Rising Costs and Refund Backlog

What This Means to Distributors: Distributors are facing a dual challenge of higher tariff-driven costs on new imports while tying up cash and resources pursuing refunds on prior duties.

Tariff policy is entering a new and more complex phase in early April, as the U.S. simultaneously imposes revised duties on imported metals and begins unwinding billions of dollars in previously collected tariffs.

As of April 6, updated tariffs on steel, aluminum and related products have taken effect, expanding the range of goods subject to duties and increasing the effective cost of many industrial imports. At the same time, distributors and other importers are preparing to file for refunds tied to tariffs invalidated earlier this year, setting off what could become one of the largest duty recovery efforts in recent history.

The overlap is creating a two-sided pressure point for distributors: rising forward costs and delayed recovery of past payments.

The revised tariff framework applies duties more broadly across metal-intensive products and, critically, shifts how those duties are calculated. Tariffs are now assessed on the full value of imported goods rather than only the metal content, a change that significantly increases the effective duty burden across a wide range of industrial and construction-related items.

For distributors, that shift is immediate. Products that previously carried limited tariff exposure now face materially higher landed costs, particularly in categories such as fasteners, fittings, HVAC components, and fabricated assemblies. Supplier pricing is beginning to reflect those changes, with more frequent updates tied to tariff classifications and sourcing.

At the same time, the administration has extended tariffs into additional sectors, including pharmaceuticals, signaling a broader use of trade policy that could expose more product categories to future duties.

Running in parallel is a large-scale refund process tied to tariffs struck down by the Supreme Court earlier this year. The ruling invalidated duties imposed under emergency powers, requiring the federal government to return an estimated $166 billion to importers.

U.S. Customs and Border Protection is preparing to process claims covering more than 50 million import entries. More than 26,000 companies have already registered to seek refunds, and officials say payments could begin within weeks, though processing timelines may stretch beyond 45 days as the agency works through the volume and complexity of claims.

The system remains incomplete, and a significant share of claims is expected to face delays, particularly where entries have already been finalized or require additional validation.

For distributors, the refund process is neither automatic nor straightforward. Claims must be filed at the entry level, supported by detailed documentation including tariff classifications, country-of-origin data, and proof of eligibility. The process requires coordination across finance, procurement, and compliance teams, adding an administrative burden at a time when companies are already managing pricing volatility.

The timing mismatch between tariff payments and refunds is creating additional strain. Duties are paid upfront at the time of import, while refunds may take weeks or months to process, tying up working capital and complicating margin management.

The combined effect is a fragmented pricing environment in which distributors must account for both rising current costs and uncertain future recoveries.

That dynamic is already shaping pricing strategy across the sector.

At MSC Industrial Supply, executives said tariff-driven price increases are continuing to move through the business in stages, with additional adjustments planned in the coming months. The company implemented what CEO Martina McIsaac described as a “surgical” price increase in March, following earlier actions in January, and expects further increases in late May and June.

Ryan Mills, MSC’s head of investor relations, said pricing in the back half of the fiscal year is expected to remain elevated, in the range of 6.5% to 7% year over year, as earlier tariff-related increases are lapped and new adjustments take effect.

McIsaac said the company has not yet seen significant added cost pressure from suppliers tied to the latest tariff changes, noting that MSC is not the importer of record for most of its purchases. That structure can delay the timing of cost pass-through, though the broader trend toward higher pricing remains intact.

The distinction underscores a widening gap across the industry. Distributors that import directly are already absorbing higher tariff costs and managing refund filings, while those that rely on suppliers face a lag before those costs are reflected in pricing.

Even so, the direction is consistent: pricing is rising, and it is becoming more dynamic.

Efforts to shift sourcing away from China continue, but progress remains uneven. While some distributors have expanded supplier networks in Southeast Asia, Mexico and India, constraints around capacity, cost and logistics have limited how quickly those changes can scale. As a result, China remains embedded in many supply chains, leaving distributors exposed to ongoing tariff risk even as policy evolves.

Inventory and purchasing strategies are also adjusting. Some distributors are pulling forward orders ahead of tariff changes or repositioning inventory closer to ports to reduce total landed cost. Those moves can mitigate risk but require additional working capital and introduce new operational complexities.

What is emerging is a fundamentally different operating environment. Tariffs are no longer isolated policy events. They are an ongoing and evolving factor shaping cost structures, pricing behavior, and supply chain strategy across wholesale distribution.

For distributors, the challenge is no longer simply absorbing or passing through tariff costs. It is managing a system in which duties are being imposed, recalculated, and refunded at the same time, requiring tighter coordination across pricing, procurement, and compliance than at any point in recent years.
