In China-US cross-border trade, shipping from China to the US is the core and most commonly used transportation method. Its shipping volume, freight rates, and timeliness fluctuate significantly with seasons and market demand. Grasping the rules of peak seasons is crucial for freight forwarders and foreign trade enterprises to control costs, avoid risks, and improve efficiency. Many freight forwarders and shippers easily fall into the misunderstanding that "peak season is a fixed month", ignoring the subdivided differences and influencing factors of peak seasons, which leads to difficulties in booking space, skyrocketing freight rates, or cargo delays. This article will detail the peak periods of shipping from China to the US, core influencing factors, and differences in peak seasons between different routes, combined with the latest authoritative data and practical suggestions, to help practitioners accurately grasp the rhythm of peak seasons.

What Are the Specific Stages of the Core Peak Season for Shipping from China to the US?

The peak season for shipping from China to the US is not a single fixed period, but three core stages formed around US local consumption nodes and China's production cycle. Each stage has different shipping volume, freight rates, and operation priorities. Freight forwarders need to note that the division of peak seasons is not absolute; it will be affected by factors such as the global trade environment, port efficiency, and policy changes, and must be flexibly adjusted according to the actual situation of the year, rather than mechanically applying the rules of previous years.

First Peak Season: August-October (Core Period for Christmas Stocking)

This is the busiest and highest shipping volume peak season for shipping from China to the US throughout the year. The core driving force is the stocking demand for the US Christmas shopping season. US retailers usually centrally purchase Chinese-made holiday gifts, household goods, electronic products, etc., from August to October every year to cope with the Black Friday promotion at the end of November and the Christmas peak season in December. This demand directly drives a sharp increase in shipping volume from China to the US.

According to the "Annual Report on the Shipping Market from China to the US" released by the Shanghai Shipping Exchange in May 2026, the total shipping volume from China to the US from August to October 2025 reached 2.86 million TEU, accounting for 32% of the total annual shipping volume. Among them, the shipping volume of the US West Route increased by 18.7% year-on-year, and the US East Route increased by 15.3% year-on-year. In the same period, the latest review data of the Freightos Baltic Index (FBX) in May 2026 showed that the freight rate from China to major US West ports in September 2025 increased by 42% compared with July, and the freight rate to major US East ports increased by 35%, hitting the peak annual freight rate.

The recommended approach is: freight forwarders should start preparing for peak season booking at the beginning of July, sign a fixed space agreement (FCA) with shipping companies to lock in space and basic freight rates, avoiding the situation of no space available or skyrocketing freight rates in the later stage of the peak season; for shippers, it is recommended to start the stocking and booking process 45 days in advance, reserving sufficient time for customs declaration, loading, and transportation, to avoid missing the Christmas sales node due to overcrowding and port congestion.

A common misunderstanding is: some freight forwarders and shippers do not start booking until mid-August. At this time, high-quality space has been occupied, and they can only choose temporary space with higher prices, or even face the risk of container skipping; some shippers also ignore the congestion problem of US West ports and fail to reserve sufficient port arrival buffer time, resulting in inability to pick up containers in a timely manner after the goods arrive at the port and missing the sales peak season.

Second Peak Season: January-February (Pre-Spring Festival Stocking Period)

This peak season is mainly affected by China's Spring Festival holiday, belonging to the "pre-holiday restocking wave", with a short duration but concentrated shipping volume. As the world's manufacturing center, most Chinese factories will centrally produce and ship goods 1-2 months before the Spring Festival to avoid delivery delays caused by work stoppages during the Spring Festival holiday. US shippers will also purchase in advance to cope with the supply gap during China's Spring Festival, thus driving a short-term surge in shipping volume from China to the US.

According to the updated monthly review data of the Shanghai Shipping Exchange in May 2026, the shipping volume from China to the US in January 2026 reached 800,000 TEU, an increase of 4% month-on-month compared with December 2025. Although it decreased by 14% year-on-year, it was still significantly higher than the month-on-month decline rate of the overall Asian shipping volume to the US (10%), highlighting the driving effect of the pre-Spring Festival restocking wave. In the same period, the latest data released by the official website of the Port of Los Angeles in May 2026 showed that the container throughput of the Port of Los Angeles in the first two months of 2026 reached 1.636 million TEU, of which goods shipped from China to the US accounted for 49%, the highest in the past four months.

Freight forwarders need to note that the core pain point of this peak season is "tight time and lack of resources". Before the Spring Festival, resources such as trucking, customs brokers, and dock workers are tight, which is prone to problems such as truck queuing, customs declaration delays, and delayed loading. In addition, freight rates fluctuate greatly, so it is necessary to coordinate resources in advance.

The recommended approach is: freight forwarders should book trucking 3-5 days in advance, choose a reliable fleet to avoid breakdowns or delays on the way; review customs declaration documents in advance to ensure consistency between documents and consistency between documents and goods, reducing the probability of inspection; at the same time, confirm the sailing schedule during the Spring Festival with the shipping company, avoid the suspension period during the holiday, and reasonably plan the booking time.

Third Peak Season: March-April (Post-Holiday Restocking Period)

After the Spring Festival holiday, Chinese factories fully resume production, and US shippers will also replenish the inventory consumed during the Spring Festival, forming a short-term restocking peak season. Although the shipping volume in this stage is not as high as that in August-October, the overall shipping volume is still higher than that in the off-season, and the freight rate is relatively stable, which is an important window period for freight forwarders and shippers to optimize transportation costs.

According to the latest data of the Freightos Baltic Index (FBX) in May 2026, the market freight rate (shipping and shipping surcharges) from Shanghai to major US West ports in April 2026 was 2,568 US dollars per 40-foot container, a decrease of 1.2% from the previous week; the freight rate from Shanghai to major US East ports was 3,652 US dollars per 40-foot container, a slight decrease of 0.9% from the previous week. The overall freight rate showed a steady downward trend, and the space supply was relatively sufficient.

A common misunderstanding is: some freight forwarders believe that this stage is not a core peak season, ignoring space booking and resource coordination, leading to tight space on some popular routes; some shippers also pursue low prices excessively and choose small freight forwarders with incomplete qualifications, resulting in container skipping, delays and other problems with the goods.

What Are the Core Factors Affecting the Peak Season of Shipping from China to the US?

The formation of the peak season for shipping from China to the US is not caused by a single factor, but the result of the combined effect of various factors such as US consumer demand, China's production cycle, port efficiency, and policy environment. Freight forwarders need to note that accurately grasping these influencing factors can help predict changes in peak seasons in advance and avoid operational risks.

Is US Local Consumer Demand the Core Driving Force?

Yes, US local consumer demand is the core factor determining the peak season for shipping from China to the US. The US is one of China's largest export markets, and its consumption nodes directly determine the transportation rhythm of China's export goods. In addition to core nodes such as the Christmas shopping season and Black Friday promotion, US Thanksgiving, back-to-school season, etc., will also drive the transportation demand of some categories of goods, indirectly affecting the peak season period.

According to the latest data released by UN Comtrade in May 2026, the total value of goods imported by the US from China in 2025 reached 589 billion US dollars, of which more than 80% were transported by sea. The import volume during the Christmas season (November-December) and Black Friday promotion accounted for 35% of the total annual import volume, which is also the core reason why August-October became the core peak season. Freight forwarders need to note that they must closely monitor changes in the US consumer market. If US consumer demand is weak, it may lead to a decline in peak season shipping volume and freight rates, and it is necessary to adjust operational strategies in a timely manner.

Will China's Production Cycle and Policies Affect the Peak Season?

China's production cycle and related policies also have a significant impact on the peak season. In addition to the pre-holiday and post-holiday restocking peak seasons caused by the Spring Festival holiday, China's environmental protection policies, production capacity adjustments, etc., will also affect the export rhythm of goods, thereby affecting the shipping volume from China to the US. For example, environmental production restrictions may lead to a decline in factory production capacity and delayed delivery of goods, indirectly extending the peak season cycle; while production capacity recovery will promote the concentrated release of shipping volume, exacerbating peak season congestion.

The recommended approach is: freight forwarders should closely monitor changes in China's manufacturing production capacity and related policy adjustments, communicate with suppliers in advance to understand the stocking progress, and avoid inability to deliver goods on time due to insufficient production capacity or policy restrictions; at the same time, pay attention to changes in China-US trade policies, such as tariff adjustments and customs clearance policy changes, and adjust transportation plans in a timely manner to avoid policy risks.

How Do Port Efficiency and Capacity Supply Affect the Peak Season Experience?

Port efficiency and capacity supply are key factors affecting the peak season transportation experience, directly determining the transportation timeliness and cost of goods. The congestion situation, loading and unloading efficiency of core ports for shipping from China to the US (Shanghai Port and Ningbo Port in China, Los Angeles Port and Long Beach Port in the US), as well as the capacity investment of shipping companies, will all affect the transportation rhythm of the peak season.

According to the latest data of the Shanghai Shipping Exchange in May 2026, the average delay time of major US West ports during the 2025 peak season (August-October) reached 2.1 days. Although it has improved compared with 2024, it will still lead to inability to pick up containers in a timely manner after the goods arrive at the port, resulting in additional port detention fees and storage fees. Freight forwarders need to note that during the peak season, they should prioritize direct routes, avoid routes with multiple transshipments, and choose leading shipping companies with stable space and high on-time rates (Maersk, MSC, COSCO Shipping, etc.) to reduce the risk of delays.

Are There Differences in Peak Seasons Between US West and US East Routes? How to Respond?

Shipping from China to the US is mainly divided into the US West Route (calling at Los Angeles Port, Long Beach Port, etc.) and the US East Route (calling at New York Port, Savannah Port, etc.). The two routes have obvious differences in peak season periods, shipping volume characteristics, and operation priorities. Freight forwarders need to formulate targeted response strategies to avoid a "one-size-fits-all" operation model.

US West Route: More Concentrated Peak Season, Higher Congestion Risk

The US West Route is closer to China with faster transportation timeliness (12-18 days for direct shipping), making it the preferred route for most shippers. Therefore, the peak season is more concentrated, mainly in August-October and January-February, with the peak shipping volume in September. According to the latest review data released by the official website of the Port of Los Angeles in May 2026, the container volume shipped from China to the US handled by the Port of Los Angeles in September 2025 reached 587,000 TEU, an increase of 16.2% year-on-year, the highest monthly shipping volume of the year.

Freight forwarders need to note that the core pain points of the US West Route during the peak season are port congestion and container skipping risks. Especially at Los Angeles Port and Long Beach Port, problems such as anchoring queues, slow berthing, and slow loading and unloading are prominent during the peak season, with ETA generally delayed by 7-21 days. The recommended approach is: during the peak season, prioritize alternative ports such as Oakland Port and Tacoma Port. Although the sea freight is slightly higher, the customs clearance and container pickup speed after arriving at the port are faster, and the total cost is more optimal; at the same time, confirm the space with the shipping company in advance and sign a non-skipping agreement to avoid cargo delays caused by container skipping.

US East Route: Flatter Peak Season, Smaller Freight Rate Fluctuations

The US East Route is farther from China with longer transportation timeliness (25-30 days for direct shipping), mainly serving shippers in the eastern part of the US. The peak season is relatively flat. In addition to the core peak season in August-October, the shipping volume during the post-holiday restocking period in March-April is also relatively stable, and the fluctuation range of freight rates is smaller than that of the US West Route.

According to the latest freight rate report released by Drewry in May 2026, the peak season freight rate increase of the US East Route in 2025 was 28%, far lower than the 42% of the US West Route, and the space supply was relatively sufficient with low congestion risk. The recommended approach is: for shippers with low requirements on transportation timeliness and large cargo volume, the US East Route can be selected to control costs by taking advantage of the stable peak season freight rates; freight forwarders can establish long-term cooperation with customs brokers at US East ports, pre-review customs clearance documents in advance, and ensure fast customs clearance after the goods arrive at the port to improve delivery efficiency.

Practical Guide for Peak Season Response: What Should Freight Forwarders and Shippers Do?

During the peak season, the shipping market from China to the US presents the characteristics of "tight space, high freight rates, slow timeliness, and many risks". Freight forwarders and shippers need to plan in advance and optimize processes to successfully complete the transportation. The following are targeted practical suggestions covering core links such as booking, stocking, and customs clearance.

Booking Link: Lock in Space in Advance to Avoid Price and Space Risks

The recommended approach is: freight forwarders should sign fixed space agreements with shipping companies and first-class freight forwarders 1-2 months before the peak season to lock in space and basic freight rates, avoiding no space available or skyrocketing freight rates in the later stage of the peak season; at the same time, reserve 2-3 alternative shipping companies for the same route to avoid delays in the entire shipment due to overcrowding of one shipping company. For shippers, it is recommended to start the booking process 45 days in advance (Christmas peak season) or 30 days in advance (pre-Spring Festival peak season), clarify the booking terms, and include "no container skipping, no ship change, no call change" in the booking confirmation to reduce the risk of breach of contract.

Freight forwarders need to note that it is not recommended to choose low-priced space during the peak season. Low-priced space is often accompanied by a high container skipping rate, which will increase delay costs and rebooking fees; priority can be given to the "space guarantee price". Paying 5-10% more sea freight in exchange for "no container skipping and on-time sailing" makes the overall cost more controllable.

Stocking and Operation Links: Compress Cycles and Improve Efficiency

The recommended approach is: shippers should arrange production in advance, reserve 7-10 days of production buffer time, and avoid the situation of "goods ready but no space, space available but goods not ready"; stock in batches, first stock core goods to ensure the first batch is shipped on time, and the second batch is supplemented to balance timeliness and cost.

Freight forwarders should book trucking 3-5 days in advance, choose a reliable fleet to avoid truck queuing or delays; complete loading on the same day, complete VGM (Verified Gross Mass) declaration in advance to avoid inability to load due to VGM errors; review customs declaration documents 3 days in advance to ensure the documents are complete and correct, reducing the probability of inspection.

Customs Clearance and Port Arrival Links: Plan in Advance to Avoid Delay Risks

Freight forwarders need to note that the US Customs inspection rate will increase during the peak season, especially for LCL goods and sensitive categories. It is necessary to prepare complete customs clearance documents in advance, including commercial invoices, packing lists, certificates of origin, etc., to ensure that the declared information is true and accurate, avoiding cargo detention due to false declaration.

At the same time, communicate with the US destination port customs broker in advance, pre-review the customs clearance documents, declare immediately after the goods arrive at the port, and strive for priority inspection and rapid release; book the destination port trucking in advance to ensure that the container is picked up immediately after the goods are released, avoiding port detention fees and storage fees.

Conclusion

The peak season for shipping from China to the US is mainly divided into three core stages: August-October (core period for Christmas stocking), January-February (pre-Spring Festival stocking period), and March-April (post-holiday restocking period). Among them, August-October is the busiest peak season of the year, with the highest shipping volume and freight rates. The formation of the peak season is mainly affected by factors such as US consumer demand, China's production cycle, port efficiency, and capacity supply, and there are obvious differences in the peak season characteristics between the US West and US East routes.

Freight forwarders need to note that the core of grasping the peak season rules is "advance planning, flexible adjustment, and risk prevention and control", avoiding common misunderstandings. By locking in space in advance, optimizing operation processes, and coordinating high-quality resources, they can effectively control costs and avoid delay risks. For shippers, they need to choose the appropriate route and booking time according to their own cargo characteristics and timeliness needs, and cooperate with reliable freight forwarders to ensure the smooth delivery of goods. With the continuous development of China-US trade and the continuous optimization of the global supply chain, the peak season rules for shipping from China to the US will also adjust accordingly. Practitioners need to continuously pay attention to market changes, adjust operational strategies in a timely manner, and gain an advantage in the peak season competition.
