What’s the Latest with Section 321 in 2025?
The trade landscape in 2025 is evolving rapidly, as significant changes impact Section 321, a U.S. Customs provision that allows duty-free imports on shipments valued under $800. With new tariffs, policy shifts, and geopolitical challenges reshaping the landscape, warehousing and fulfillment providers are pivoting to address the needs of businesses reliant on Section 321. Let’s delve into the recent developments with Mexico, Canada, and China, explore policy changes under the Trump administration, and examine the ripple effects on e-commerce and logistics.

Where We’re At Now: The End of the ‘Border-Skipping’ Loophole in Mexico
In December 2024, Mexican President Claudia Sheinbaum announced an end to the ‘border-skipping’ strategy. This loophole allowed U.S. e-commerce sellers to route Chinese goods through Mexico, repack them, and ship them duty-free under Section 321. Leveraging Mexico’s lower labor costs and proximity to the U.S. market, this strategy had become a cornerstone for many businesses seeking cost-efficient fulfillment solutions.
However, the new decree introduced sweeping changes. Import duties on finished apparel products increased from 20-25% to 35%, while duties on textiles rose from 10% to 15%. Additionally, the IMMEX program now restricts finished apparel and textile articles classified under HTS Chapters 61, 62, and 63.
These changes have disrupted operations for Mexican warehouses and fulfillment centers, creating challenges in inventory management and cross-border shipping. Many companies are reevaluating their supply chains, considering reshoring back to U.S. warehouses or shifting sourcing to countries in Southeast Asia to maintain Section 321 compliance in 2025.

Trump’s Proposed Tariffs and Section 321 in 2025
President-elect Donald Trump’s proposed tariffs include a 25% levy on imports from Mexico and Canada and an additional 10% on Chinese imports, with the potential for escalation. For warehousing and fulfillment providers, these tariffs present logistical and cost challenges that ripple across the supply chain.
Businesses that rely on low-cost imports must now grapple with higher prices, forcing them to explore reshoring, nearshoring, or diversifying suppliers. For e-commerce fulfillment centers, adapting to these changes means rethinking inventory strategies, implementing cost-efficient solutions, and exploring multi-channel fulfillment options.

Section 321 in 2025: Policy Shifts and Fulfillment Impacts
The elimination of duty-free imports from China under Section 321 removes a key cost-saving mechanism for many direct-to-consumer brands. Additionally, a $2 per-package fee for shipments passing through U.S. Customs adds new financial pressures for high-volume e-commerce businesses.
Key Adaptation Strategies:
- Reshoring Warehousing: Transitioning fulfillment operations to U.S.-based warehouses to reduce cross-border complexities.
- Supplier Diversification: Sourcing from Vietnam, India, and other Southeast Asian countries to maintain competitive pricing.
- Optimized Fulfillment Workflows: Streamlining inventory management and leveraging advanced warehousing technologies to improve efficiency.

Geopolitical and Security Concerns
The trade policy changes intersect with growing geopolitical tensions. National security concerns around platforms like TikTok, Temu, and Shein further complicate the landscape. Proposed bans on these platforms could disrupt direct imports from China and impact businesses reliant on their logistics networks.
Reappointing Peter Navarro as a senior trade advisor signals an aggressive trade agenda, with tariffs potentially expanding to additional industries. Fulfillment providers must stay agile, preparing for shifts in global supply chains and leveraging strategic partnerships to mitigate risks.

Supply Chain Adjustments for Section 321 in 2025
Policy changes are driving businesses to rethink supply chain strategies, with many embracing reshoring and leveraging U.S.-based distribution hubs. Fulfillment centers, such as those in Texas, Nevada, and Indiana, are becoming critical nodes in new logistics frameworks.
Companies are also exploring less-than-truckload (LTL) and pool distribution networks to optimize last-mile delivery while reducing overall costs. Ports like Laredo, Texas, are gaining prominence as cross-border trade routes shift, and businesses reevaluate warehouse networks to adapt to these changes.

Predictions for Warehousing and Fulfillment in 2025
The changes to Section 321 in 2025 will create turbulence across global e-commerce and logistics. Companies that successfully adapt by reshoring, diversifying suppliers, and leveraging innovative fulfillment solutions will gain a competitive edge. However, those that fail to evolve risk operational disruptions and rising costs.
Legal challenges to Trump’s tariffs are expected, but businesses must prepare for their enforcement. Fulfillment providers that focus on agility, efficiency, and strategic partnerships will be best positioned to thrive.

Bottom Line
The shifting landscape of Section 321 in 2025 underscores the importance of adaptability in warehousing and fulfillment. With tariffs, policy changes, and geopolitical tensions shaping the trade environment, companies must embrace flexible supply chain strategies and invest in robust fulfillment solutions. Whether through reshoring, exploring alternative sourcing, or optimizing fulfillment networks, businesses must remain agile to navigate the complexities of Section 321 in 2025.
