Чоку сезонундагы кошумча төлөмдөрдүн түшүндүрмөсү: 4-чейректе Кытайдан АКШга жеткирүү
Every year, sometime around August, importers shipping from China to the United States begin to see the same thing on their freight invoices: A new line item that wasn’t there in June. It’s commonly called PSS, GRI or a combination of the two. It can tack on hundreds or even thousands of dollars to move a single container. If you’re planning a Q4 inventory plan around Black Friday, Cyber Monday and the holiday shopping rush, knowing these fees is a must. It’s the difference between a landed-cost prediction that holds and one that quietly unravels in October.
In this post, we’ll unpack peak season surcharges, the China-USA lane’s performance as we enter Q4 2026, the current rate situation and what shippers can realistically do to put a lid on costs without sacrificing reliability. Later in the season we will look at how ocean freight peak rates compare to the parcel and air-side surcharges that stack on top of them.
What Exactly Is a Peak Season Surcharge?
A peak season surcharge is a temporary premium that ocean carriers add to their base freight rate when demand for container space exceeds the capacity they have deployed on a certain trade lane. It is not a tax . Nor is it related to fuel or currency as a bunker adjustment factor . It’s just a case of more shippers wanting space on the same ships. The carriers apply the premium to cover the operational stress of operating near full and to discourage marginal reservations that might otherwise overflow the schedule.
Historically, PSS windows opened in June on the transpacific eastbound lane and continued until October, in line with the retail restocking cycle ahead of the holiday season. What makes 2026 different is that carriers have been piling up PSS and GRI announcements earlier and more frequently than in a normal year, partly due to tariff-driven demand swings, and partly because capacity discipline through blank sailings has become the default playbook rather than the exception.
Why Q4 2026 Looks Different From Past Years
The single biggest element that will guide this year’s peak season is the planned expiration of the present US-China tariff truce in November 2026. Instead of spreading Christmas season orders out throughout the summer, many importers moved them forward into May and June to make the deadline, creating an abnormally sudden and early increase in demand, rather than the gradual ramp-up carriers typically plan for.
This front-loading has substantial effects for Q4. Some analysts see a softer tail end of the season, with rates possibly lowering as the initial surge works through the system. With so much freight already moved ahead of schedule, Others warn that the end of the truce alone could spark a second wave of rush bookings in September and October as shippers rush to get leftover products in before a new tariff regime kicks in, which would keep surcharges elevated longer than the historical trend indicates.
Either way, the takeaway for shippers is the same: This year’s peak season is less about pure retail seasonality and more about trade-policy timing, which makes it much difficult to forecast based on last year’s schedule.
The Surcharge Stack: PSS, GRI, and Everything Else
Carriers don’t usually just have one cost. Instead, a shipment in motion during peak season usually has a few charges on top of the regular ocean freight rate. The reason knowing the whole stack is important is that a quote that shows simply the base rate can underestimate the real landed cost by a considerable margin once everything is added up.
| Кошумча акы түрү | Бул эмнени камтыйт | Typical Q4 Range (per container) |
| Жалпы курстун өсүшү (GRI) | A broad base-rate hike carriers apply across a trade lane, usually announced two to four weeks ahead. | 300 1,200 - XNUMX XNUMX АКШ доллары |
| Жогорку сезондун кошумча акысы (PSS) | A demand-driven add-on layered on top of the base rate during high-volume months. | 200 800 - XNUMX XNUMX АКШ доллары |
| Жабдуулардын тең салмаксыздыгы үчүн кошумча төлөм (EIS) | Compensates carriers for repositioning empty containers back to export-heavy origins like South China. | 150 500 - XNUMX XNUMX АКШ доллары |
| Emergency Fuel / Bunker Surcharge | Passes on sudden bunker price swings, often tied to geopolitical disruption on major shipping corridors. | 100 400 - XNUMX XNUMX АКШ доллары |
| Порт тыгынынын ашыкча жүктөлүшү | Applied at gateways experiencing berth delays or yard backlogs, such as Los Angeles/Long Beach in Q3-Q4. | 250 500 - XNUMX XNUMX АКШ доллары |
Not all charges are on all bookings, dollar amounts vary by carrier, contract type and whether the shipment is on a long-term service contract or spot booking. Spot-rate shipments are subject to rapid PSS hikes as carriers can change spot price with little notice, but contractual caps normally safeguard contracted volume.
Current Rate Levels on the China-USA Trade Lane
By mid-2026, spot prices on the China-USA route are trading significantly higher than the lows witnessed earlier in the year. West Coast gateways such as Los Angeles and Long Beach continue to provide the shortest transit times and, in most weeks, more reasonable price, while East Coast ports carry a considerable premium connected to greater sailing distances and, in certain cases, Panama Canal routeing limits.
| Destination Gateway | Typical 40ft Container Rate | Сезондук үлгү |
| АКШнын Батыш жээги (Лос-Анжелес/Лонг-Бич) | 3,000 5,500 - XNUMX XNUMX АКШ доллары | Peaks in Q3, softens moving into Q4 |
| US East Coast (NY/NJ, Savannah) | 4,200 7,200 - XNUMX XNUMX АКШ доллары | Stays elevated longer due to longer transit and canal routing |
| АКШ булуңунун жээги (Хьюстон) | 4,000 6,500 - XNUMX XNUMX АКШ доллары | Tracks East Coast trends with a slight lag |
Outlooks for the wider container market indicate peak season rate hikes in the neighbourhood of ten to twenty percent on transpacific lanes are considered a possibility through the third quarter, with the potential for abatement once Q4 arrives and the front-loaded demand diminishes. That said, blank sailings, geopolitical disruption impacting bunker prices and tariff ceasefire timing all add levels of uncertainty not easily captured by a simple seasonal chart.
Blank Sailings, Rollovers, and Capacity Games
One of the more vexing dynamics for shippers this year has been the rise of blank sailings, where a carrier cancels a scheduled journey in an effort to constrain available capacity and sustain higher rates. It’s no longer uncommon to have many blank sailings on the transpacific in one week and the practical result is that even shippers who reserved space in advance may see their container rolled to a later voyage.
Reported rollover rates, or the percentage of booked containers that do not board the intended vessel, have ranged widely by week and carrier, with some estimates as high as thirty to sixty percent at the tightest periods. For a business timing inventory around a specific launch date or holiday shelf-stocking deadline, a rollover of even a couple of days can be costly. That’s why many shippers now add extra buffer time into their planning of Q4 shipments, rather than booking right up against the deadline.
Ports, Congestion, and the Fees Hiding Behind the Fees
Surcharges are not only for the ocean part. Once a container hits a US port, congestion on the berth or in the container yard can create its own set of charges, which tend to surge during the same August-through-October timeframe in which ocean PSS charges are already rising. Unexpected increases in import volume tend to first appear as strain at the two most-used gateways for China-origin goods, Los Angeles and Long Beach.
Importers must additionally consider chassis shortages, detention and demurrage penalties if containers are held beyond the free time allowed, and last-mile trucking rate hikes that tend to mirror port congestion, in addition to basic congestion fees. None of these show up on the original ocean freight quote but all of these become very real line items if a shipment is actually travelling through the supply chain during busy months.
How Ocean PSS Differs From Parcel and Air Peak Fees
It’s worth differentiating ocean peak season surcharges, which many e-commerce businesses also face, from the package and air-freight peak prices, because the timing and structure are not the same. Ocean PSS is computed per container, and is generally in force from around July to October, following the retail restocking cycle. Аба жүк ташуу peak fees on Asia-origin lanes typically run from August through December and are applied on a per-kilogram basis, not per-container basis, in addition to already-volatile base air prices.
For example, FedEx and UPS impose their own peak season surcharges per box during windows that typically span mid-October to mid-January to account for the direct-to-consumer Christmas shipping crush. As an Amazon FBA seller or DTC brand shipping product from China, this means you could see peak costs hit three different points in your supply chain in the same calendar quarter: once on the ocean leg into the US, again on any air expedited replenishment shipments, and a third time on parcel deliveries to end customers.
Practical Ways to Manage Peak Season Costs
Timing is the best defence against peak season surcharges. By securing capacity through a service contract ahead of the July-to-October window, a shipper gets far more predictable price than scheduling space during the tightest periods of the season. Shippers who wait until September to acquire Q4 space are nearly invariably paying the highest rates of the year and incurring the most rollover risk.
Consolidation is a second practical lever. Consolidating smaller shipments into full-container loads, or working with a partner capable of pooling less-than-container-load cargo efficiently, can be done to pool less-than-container-load cargo profitably or enhance the odds of securing space on a tight sailing schedule. Flexibility on routeing helps too, as a shipper prepared to consider both West Coast and East Coast possibilities, or a combination of direct and transhipment routings, has more paths accessible when a chosen sailing is blanked.
This is where an expert freight company can be the difference. Based in Shenzhen, Topway Shipping has been in business since 2010. With over 15 years dedicated to China-US transportation and customs clearance, the crew has already gone through a number of these peak season cycles. Topway Shipping provides services that cover the whole chain—from first-leg trucking in China, to ocean freight, to foreign кампасы, customs clearance and last-mile delivery in the United States. This means shippers have a single point of coordination, instead of having to juggle several vendors for each leg. The company also provides ocean freight services with full-container-load and less-than-containerload alternatives to key ports across the globe. This enables smaller and mid-sized importers an opportunity to tap into consolidated capacity without the need to commit to a full container on every voyage.
Finally, it’s good to just plan for the surcharge stack rather than be surprised by it. Before specific rates are revealed, putting an approximate allowance for PSS, GRI and congestion fees into a Q4 landed-cost model helps avoid being caught flat-footed when the September invoice arrives higher than planned.

Peak season surcharges are not going away, and for China-to-USA shipping specifically, 2026 has introduced a further level of complexity with tariff-truce scheduling that has not lined up well with seasonal patterns of previous years. Front-loaded demand, aggressive blank sailings and a tariff deadline smack in the midst of Q4 means shippers need to treat this year’s peak season planning as a separate beast, not a repetition of 2025.
The businesses that get through this era with the least amount of interruption tend to have a few habits in common; they book capacity early, integrate surcharge allowances into their cost models from the outset and engage with logistics partners who understand the complete chain from Chinese origin to US doorstep. Whether that means locking in a service contract in the spring, or leaning on a partner like Topway Shipping to coordinate first-leg transport, ocean freight, customs clearance and last-mile delivery under one roof, the goal is the same: turning a volatile season into something predictable enough to plan a holiday inventory strategy around.
Көп берилүүчү суроолор
Q: What is the difference between a GRI and a PSS?
A: It is a distinct, demand-driven surcharge that is added on top of the base rate during high-volume months. So shipments may have both at the same time.
Q: When do China-USA peak season surcharges typically start and end?
A: Traditionally, ocean PSS windows on the transpacific lane have started around June and extended through October, but in 2026, the timing has moved earlier, thanks to tariff-driven demand increases that pulled cargo forward into the summer months.
Q: Why are East Coast rates higher than West Coast rates?
A: East Coast gateways necessitate longer sailing distances and, depending on the route, Panama Canal transits which add expense and restrict available capacity compared to the more straightforward West Coast routes into Los Angeles and Long Beach.
Q: Can peak season surcharges be avoided entirely?
A: Not fully but there are ways to mitigate their impact such as early contracting, combining shipments into full containers, being flexible on routeing and working with a freight partner that can arrange capacity ahead of the tightest weeks of the season.
Q: How does the US-China tariff truce expiration affect Q4 2026 shipping costs?
A: The truce is slated to expire in November 2026, so many importers front-loaded orders earlier this year, pulling demand forward and perhaps creating a softer late Q4 or a second wave of urgent bookings ahead of the deadline, depending on how trade policy plays out.
