At Gain Consulting, we’re committed to helping U.S. shippers stay ahead in a rapidly evolving global trade environment. As reported by Bloomberg and S&P Global Market Intelligence, U.S. importers are facing a dual reality in 2025: robust import growth driven by consumer goods and a looming threat of tariff-driven declines. A key strategy gaining traction is the use of customs bonded warehouses, where goods can be stored for up to five years without paying duties. This blog explores the current import landscape, the role of bonded warehouses, and actionable strategies for U.S. shippers to mitigate tariff risks while optimizing their supply chains.

U.S. Imports Surge, but Tariffs Loom Large

According to S&P Global Market Intelligence, U.S.-bound imports in March 2025 reached 2.75 million TEU (Twenty-Foot Equivalent Units), marking a 10.2% annual increase and continuing a 19-quarter streak of growth. For the first quarter of 2025, total imports hit 8.14 million TEU, up 9.1% year-over-year, though these figures are slightly understated due to 2024 being a leap year and February 2025 having one fewer day. Consumer goods led the charge, with a 17.9% annual increase (excluding autos), driven by:

Home furnishings: Up 23.3%, reflecting demand for durable goods that can be warehoused for extended periods.
Appliances: Up 14.4%, fueled by consumer spending and pre-tariff stockpiling.
Consumer staples: Up 14.0%, with pharmaceuticals surging 17.3%, likely due to a pending Section 232 review of imports, which could impose national security-related tariffs.
Leisure products and toys: Up 8.4% and 5.6%, respectively, as retailers prepare for back-to-school and holiday seasons.

This growth reflects a rush to import goods ahead of anticipated tariffs, particularly those introduced by the Trump administration. However, S&P Global warns of tariff-driven declines in 2025, projecting a 4.4% annual drop in U.S. seaborne imports, with toys and apparel facing steep declines of 12.6% and 9.5%, respectively. The combination of a 10% baseline tariff, higher tariffs on Chinese goods (up to 25% or more), and the elimination of the de minimis exemption for China and Hong Kong starting May 2, 2025, is reshaping import strategies.

Key Takeaway: U.S. shippers are capitalizing on strong consumer demand but must prepare for cost increases and reduced import volumes as tariffs take effect. Strategic planning is critical to maintain profitability.

The Rise of Customs Bonded Warehouses

As tariffs threaten to inflate import costs, U.S. importers are turning to customs bonded warehouses to defer duties. These federally licensed facilities allow goods to be stored for up to five years without paying tariffs, offering a critical buffer against rising costs. Bloomberg reports a surging demand for bonded warehouse space, with inquiries to providers like Flexe, a startup matching shippers with warehouse space, increasing sixfold in 2025.

Bonded warehouses provide several advantages:

Duty Deferral: Importers can store goods without paying duties until they are withdrawn for U.S. consumption, preserving cash flow.
Re-Export Flexibility: Goods can be re-exported duty-free, ideal for shippers serving global markets.
Long-Term Storage: The five-year storage window allows shippers to wait out tariff changes or market shifts, particularly for “long-lived” consumer goods like home furnishings and appliances, which saw import gains of 23.3% and 14.4% in March.
Customs Compliance: Bonded warehouses are under U.S. Customs Service oversight, ensuring regulatory adherence while simplifying clearance processes.

This surge in demand reflects a broader trend of pre-tariff stockpiling, as shippers rush to import goods before duties escalate. For example, pharmaceuticals and consumer staples, up 17.3% and 14.0%, respectively, are being warehoused to hedge against potential Section 232 tariffs, which could target imports deemed critical to national security.

Key Takeaway: Customs bonded warehouses are a powerful tool for deferring tariff costs, especially for durable goods. However, limited warehouse availability due to high demand requires shippers to act quickly to secure space.

Tariff Pressures and Regulatory Shifts

The 2025 tariff landscape is complex, with multiple policies impacting U.S. shippers:

Reciprocal Tariffs: A 10% baseline tariff applies to most imports, with 25% tariffs on goods from China, Canada, and Mexico, and additional duties on countries purchasing Venezuelan oil starting April 2, 2025. These are in addition to existing Section 232, Section 301, and antidumping/countervailing duties (AD/CVD).
De Minimis Exemption Changes: Starting May 2, 2025, the $800 de minimis exemption will no longer apply to Chinese and Hong Kong goods, increasing costs for low-value e-commerce shipments. New customs fees, such as FedEx’s $4.50 or 2% disbursement fee, will further raise costs.
Section 232 and 301 Tariffs: The Section 232 review of pharmaceuticals and other goods could lead to new duties, while Section 301 tariffs on $320 billion of Chinese goods (Lists 3 and 4A) face legal challenges but remain in effect, driving up costs for consumer goods like clothing (28.3%-36.9%) and toys (30.4%).
Retaliatory Tariffs: Canada has imposed 25% tariffs on $20.8 billion of U.S. goods, targeting products like appliances and furniture, while China has introduced export controls on critical minerals. These measures could disrupt supply chains and increase costs for U.S. shippers.

S&P Global notes that “long-lived” consumer goods, such as home furnishings and appliances, are seeing the fastest import growth due to their suitability for extended warehousing, making bonded warehouses particularly attractive. However, tariff uncertainty is prompting businesses to adopt a “wait-and-see” approach, potentially slowing imports in Q2 2025.

Key Takeaway: Tariffs are driving up costs and complexity, but bonded warehouses offer a strategic hedge. Shippers must navigate retaliatory tariffs and customs changes to avoid disruptions.

Economic and Consumer Impacts

The tariff-driven cost increases are poised to ripple through the U.S. economy. S&P Global estimates that consumer goods like clothing, toys, and smartphones could face 27-30% additional duties, leading to higher retail prices. This could reduce consumer purchasing power, particularly for millennials, who are not yet “hard-core” consumers like older generations.

Logistics Management’s Jeff Berman highlights that e-commerce growth is reshaping logistics, with faster delivery models straining traditional freight methods. The rise in consumer goods imports (e.g., 17.9% for non-auto goods) reflects this trend, but tariff-induced price hikes could dampen demand, especially for discretionary items like leisure products and toys, which saw modest gains of 8.4% and 5.6%.

Customs bonded warehouses can mitigate these impacts by allowing shippers to delay duty payments until goods are sold, preserving cash flow and enabling flexible pricing strategies. However, the Federal Register projects that new tariffs could generate $5.9 billion to $7.8 billion in additional revenue in 2025, increasing consumer prices and reducing import volumes.

Key Takeaway: Tariffs will raise consumer prices, potentially curbing demand for discretionary goods. Bonded warehouses can help shippers manage costs and maintain competitiveness.

Strategic Recommendations for U.S. Shippers

To thrive in this high-tariff environment, U.S. shippers must adopt proactive strategies. Gain Consulting recommends the following:

Secure Bonded Warehouse Space: With demand for bonded warehouses surging (Flexe reports a 6x increase in inquiries), lock in space now to defer duties on high-value or long-lived goods like home furnishings and appliances.
Diversify Supply Chains: Reduce reliance on Chinese imports by sourcing from USMCA countries (e.g., Mexico) or Southeast Asia (e.g., Vietnam, Thailand), which face lower or no tariffs.
Optimize Customs Compliance: Prepare for increased scrutiny and new fees by ensuring accurate documentation, including Certificates of Origin. Use the Enhanced Entry Process proposed by CBP to streamline low-value shipments.
Leverage Foreign Trade Zones (FTZs): Like bonded warehouses, FTZs allow duty deferral and re-export without tariffs. They’re ideal for assembly or processing, particularly for pharmaceuticals and electronics.
Adjust Pricing and Inventory: Share tariff costs with suppliers and consumers through transparent surcharges or price adjustments. Stockpile goods like toys and apparel before Q2 2025 to avoid projected 12.6% and 9.5% import declines.
Invest in Visibility Tools: Use shipment tracking and landed cost calculation software to anticipate customs delays and communicate price changes to customers.
Monitor Section 232 Developments: The pending review of pharmaceuticals and other goods could introduce new tariffs. Stay informed and warehouse critical supplies to hedge against cost spikes.

Key Takeaway: A multi-faceted approach—combining bonded warehouses, diversified sourcing, and robust compliance—will help shippers navigate tariffs and maintain profitability.
