Navigating the New U.S. Metal Tariffs: How Plastic & Rubber Alternatives Can Shield Your Bottom Line

Strategic Solutions for OEM Manufacturers

The information provided in this article reflects the tariff situation as of August 18, 2025. Tariff policies and regulations are continually evolving, and Trim-Lok is committed to providing accurate, timely updates as new developments emerge. Please check back regularly for our latest insights and guidance for OEMs.

The U.S. manufacturing landscape underwent significant shifts throughout 2025. On March 12, tariffs on imported steel and aluminum increased sharply to 25%, and then escalated further on June 4 to a substantial 50% for most countries, significantly intensifying cost pressures on OEMs. Exceptions remain limited, notably a temporary 25% rate for imports from the United Kingdom, pending review.

On April 2, the administration introduced "Liberation Day" tariffs. This is a baseline 10% tariff on nearly all global imports (excluding Canada and Mexico) effective April 5, accompanied by reciprocal tariffs ranging from 10–49% for approximately 60 countries. These tariffs faced legal scrutiny when the U.S. Court of International Trade ruled on May 28 that they exceeded presidential authority and suspended them. However, an appellate court reinstated the tariffs pending ongoing legal proceedings.

Most recently, on July 2, a new trade deal introduced a 20% tariff on Vietnamese imports and a 40% tariff on products transshipped through Vietnam, aimed at preventing circumvention of existing tariffs. Concurrently, negotiations with China continue, influencing tariff dynamics further. Amid these rapid and ongoing developments, manufacturers continue to face heightened challenges maintaining profitability, competitiveness, and supply chain stability.

Immediate Impact on Manufacturing Costs

The sharp increase in tariffs significantly impacts raw material pricing. With steel tariffs now at 50%, manufacturers face substantial hikes in operational expenses, particularly affecting industries such as automotive, construction, and manufacturing. For example, a construction equipment parts manufacturer previously spending $1 million annually on imported steel could now incur an additional cost of $500,000, dramatically affecting margins and end-product pricing.

Key Challenges for OEMs and Suppliers

The intensified impact of steel tariffs presents profound challenges, notably disrupting supply chains and increasing lead times. OEMs and suppliers must rapidly adjust sourcing strategies to manage rising costs and supply shortages, exacerbated by potential retaliatory tariffs and unpredictable policy changes. Maintaining competitiveness and profitability has become more complex than ever.

Why Non-Metal Alternatives Are on the Rise

Faced with this unpredictability, manufacturers increasingly recognize the benefits of adopting non-metal alternatives, including plastics and rubbers. Trim-Lok offers these materials, which provide inherent advantages, from cost savings and enhanced design flexibility to significantly reduced weight.

Components made from these materials not only help OEMs mitigate immediate tariff impacts but also provide long-term stability through more predictable pricing and supply chain resilience.

A Cost-Saving Scenario

Consider a mid-sized OEM manufacturer previously relying on steel-based hinges for heavy-duty equipment enclosures and trailer toolboxes. Switching to Trim-Lok’s Endura-Hinge™—made from a durable, all-plastic, one-piece solution—provided immediate cost relief. The OEM reduced their annual procurement costs by approximately 20%, decreased assembly time by streamlining installation, and significantly mitigated the impacts of fluctuating steel tariffs.

This hypothetical scenario mirrors numerous real-world cases in which Trim-Lok’s customers can successfully transition from metal to non-metal alternatives, resulting in tangible cost savings and enhanced product reliability.
