Shipping Surge After US-China Tariff Deal: Seller Costs & Availability Insights
On May 12, 2025, the United States and China reached a pivotal tariff reduction agreement, aiming to stabilize trade relations and ease the cost pressures on importers. While the de minimis exemption remains suspended, the agreement significantly lowered tariffs, impacting shipping dynamics for e-commerce sellers worldwide.
Key Outcomes of the May 12 Tariff Deal
The agreement introduced the following adjustments:
- U.S. tariffs on most Chinese goods were reduced from 145% to 30% for a temporary 90-day period.
- China reciprocated by reducing its tariffs on U.S. goods from 125% to 10%.
- Important: The de minimis exemption—previously allowing goods under $800 to bypass duties—remains suspended. All shipments, regardless of value, are now subject to customs duties and scrutiny.

Shipping Volumes from China Surge
In the immediate aftermath of the deal, shipping volumes from China to the U.S. spiked dramatically. Data from major logistics providers show a 55% increase in bookings for container shipments, with many importers rushing to benefit from the temporary tariff reprieve before the 90-day window closes.
This surge has led to congested ports, increased demand for freight capacity, and heightened competition for shipping slots, particularly for Amazon FBA sellers reliant on just-in-time inventory models.
Rising Shipping Costs & Supply Chain Pressures
Despite lower tariffs, overall shipping costs are escalating due to supply-demand imbalances:
- Freight rates: Ocean freight rates on key trans-Pacific routes have risen by 25% since early May 2025.
- Container shortages: Limited container availability is driving up spot market prices.
- Port congestion: Delays at major U.S. ports are adding extra days to delivery timelines.

Strategic Implications for Amazon Sellers
For Amazon sellers, the shipping surge presents a mixed bag of opportunities and risks. On one hand, reduced tariffs lower landed costs, offering margin relief. On the other, rising shipping fees and fulfillment delays could erode profitability and affect customer satisfaction.
To navigate this environment effectively, sellers should:
- Reevaluate inventory strategies to mitigate stockouts.
- Negotiate better freight rates through volume consolidations.
- Adjust product pricing to reflect increased logistics expenses.
- Explore alternative sourcing regions to diversify supply chains.
Comparing 2025 to Previous Tariff Cycles
Unlike prior tariff negotiations, the May 2025 deal is distinguished by the sustained suspension of the de minimis exemption. This adds complexity for small parcel imports, particularly for dropshippers and small-scale e-commerce brands that relied on this threshold to maintain competitive pricing.
Large-scale sellers benefit more from the tariff reductions due to volume-driven cost efficiencies, while smaller sellers face tighter margins under the new duty structure.
Forecast: What Happens After the 90-Day Tariff Relief?
Industry analysts predict that if trade tensions ease further, the temporary tariff cuts could be extended. However, uncertainty remains high. Sellers are advised to prepare for potential reinstatement of higher tariffs.
Final Takeaway
The post-May 12 tariff environment requires Amazon sellers to stay agile. While tariff reductions offer a short-term advantage, rising shipping costs and supply chain disruptions necessitate proactive planning and strategic adjustments.
