Port of Portland vs. Port of Seattle: Which Is Better for Your China Imports?
If you want to bring things from China to the U.S. One of the most important routing choices you’ll make in the Pacific Northwest is where to enter the country. The Port of Portland and the Port of Seattle are both important gateways on the West Coast, but they are very different in terms of size, infrastructure, carrier services, transit reliability, and cost structure. The ports’ landscapes have changed a lot from 2025 and into 2026. This is because of changes in tariffs, new terminal operators, improvements to mega-vessels, and changes to trans-Pacific shipping routes. This post gives you the true information, the current ground truth, and the useful framework you need to send your goods from China the appropriate way.
Understanding the Two Ports: A Snapshot
Port of Seattle (Northwest Seaport Alliance)
First, it’s important to make one thing clear: when people in the shipping business talk about the “Port of Seattle,” they are usually talking about the Northwest Seaport Alliance (NWSA). Since 2015, the NWSA has run the Port of Seattle and the Port of Tacoma as a single marine cargo operating entity. Under one canopy, the two ports share terminal operations, vessel scheduling, and cargo booking systems.
In 2024, the combined NWSA handled 3.3 million TEUs, up 12.3% from 3 million TEUs in 2023. This was mostly because shippers were sending more cargo ahead of expected tariff increases in the U.S. China was by far the biggest trade partner, sending 677,071 TEUs of cargo into the country. In the first quarter of 2024, Terminal 5 in Seattle’s North Harbor finished its Phase 2 extension, which made it possible for the facility to handle ships up to 16,000 TEUs. The MSC Ilenia, a 16,000-TEU mega-vessel, made history in March 2025 by being the largest ship ever to dock at Terminal 5. This shows that Seattle is ready to handle almost any ship that sails the trans-Pacific channel.
Port of Portland (Oregon Container Terminal)
Portland’s predicament was much worse as it entered 2025. Terminal 6, Oregon’s only international container terminal, had been losing money for years. In 2024 alone, it lost $13.7 million. The Port of Portland said in April 2024 that it would stop all container operations. The government got involved after that. Governor Tina Kotek promised $40 million in state funds to keep the terminal open, but only if a private company could run it for a long time.
In September 2025, Harbor Industrial Services, a California-based firm that makes cranes and other equipment, signed a long-term lease to run Terminal 6. Harbor Industrial took over all container and breakbulk activities at Terminal 6 on January 1, 2026, and it became the Oregon Container Terminal (OCT). Starting January 16, 2026, the number of operating days will go up from four to five per week. Tim McCarthy, the president of the OCT, has said in public that the goal is to double the amount of cargo that comes through the port by 2026 and get back the 70% of Oregon-bound freight that currently goes through other West Coast ports, notably Seattle and Los Angeles.
As of early 2026, the table below shows the main changes in structure between the two port options:
| Category | Port of Portland (OCT) | Port of Seattle (NWSA) |
| Container Terminal | Oregon Container Terminal (Terminal 6) | Terminal 5 & 18 (Seattle N. Harbor); T25, T46 (Tacoma) |
| 2024 Volume | Largest decline in U.S. top 30 ports (-15.7%) | 3.3M TEUs (+12.3% YoY) |
| Operator (Jan 2026) | Harbor Industrial Services | SSA Marine, APMT, and others |
| Max Vessel Size | Panamax (Columbia River depth limit: 43 ft) | Neo-Panamax up to 16,000 TEUs |
| Active China Services | SM Line (direct); MSC resuming Q2 2026 | All major alliances; multiple weekly calls |
| On-Dock Rail | Yes (Class I connections) | Yes (BNSF and UP connections) |
| Distance from Pacific | 100 miles upriver via Columbia River | Direct Pacific coast access |
| Operating Days | 5 days/week (from Jan 16, 2026) | 7 days/week |
Transit Times: China to Each Port
For direct FCL services, it usually takes between 12 and 16 days for ships to go from major Chinese ports like Shanghai, Shenzhen, Ningbo, and Qingdao to the Pacific Northwest. The distance between Seattle and Portland doesn’t modify the ocean leg much. Ships going to the Columbia River just keep going upriver for another 100 miles past the Pacific coast. This adds about half a day to a full day, depending on the type of ship and the circumstances on the river.
Not ocean sailing time, but terminal dwell time after arrival is the most important transit variable in 2025 and 2026. According to Descartes, the Port of Seattle had delays of 6.5 to 7.5 days on average in the middle of 2025. This was routinely one of the longest delays on the West Coast. Tacoma did better, with delays that were only 2.9 days long on average in July 2025. Portland has always been less crowded, which has helped it in the past. The new OCT’s five-day work week is intended to make processing even more reliable in 2026.
| Route | Ocean Transit (Direct FCL) | Est. Port Dwell (2025) | Total Door Lead Time |
| Shenzhen → Port of Seattle | 12–14 days | 5–7.5 days | ~18–22 days total |
| Shanghai → Port of Seattle | 13–15 days | 5–7.5 days | ~19–23 days total |
| Shenzhen → Port of Portland | 13–15 days | 2–4 days (est.) | ~16–20 days total |
| Shanghai → Port of Portland | 14–16 days | 2–4 days (est.) | ~17–21 days total |
Portland’s reduced congestion levels may make up for the longer river transit time for time-sensitive cargo, especially if tariff-driven volume surges keep causing problems at Seattle’s ports.
Freight Costs: What You Actually Pay
Shipping costs from China to the U.S. There are a lot of things that affect Pacific Northwest ports, like carrier capacity, bunker fuel pricing, carrier surcharges, port handling fees, and the changing tariff environment since 2025. Seattle generally has slightly lower ocean freight prices since ships leave more often and there are more competing carrier options. Portland has had less rate competition in the past because it is a smaller port with fewer carriers. However, this is likely to change if Harbor Industrial is able to bring in more ships until 2026.
The USTR port charge regulation for Chinese-built ships, which went into effect on October 14, 2025, is one of the most important costs that all Pacific Northwest importers need to include in their budgets. Carriers are passing these taxes on to shippers through surcharges because a lot of the world’s container ships are made in China. Importers should contact their freight forwarders to check whether the chosen ship is subject to the fee and include any possible pass-through fees in their freight budgets from the start.
The removal of the $800 de minimis exemption for goods from China has made things much more expensive for e-commerce importers and direct-to-consumer businesses who used to use the threshold to avoid paying formal entry duties. Now, every cargo from China, no matter how much it is worth, needs to go through formal CBP entry and pay the appropriate duty. This makes things more expensive and harder to manage.
| Cost Factor | Port of Seattle | Port of Portland |
| Ocean Freight (20′ FCL, general cargo) | ~$1,200–$2,500 (market-dependent) | ~$1,400–$2,800 (fewer carriers) |
| Port THC | Standard NWSA terminal rates | Slightly higher per-move cost (lower volume) |
| Drayage to Oregon destinations | Higher (longer inland haul) | Lower (local delivery) |
| Drayage to Washington destinations | Lower (local) | Higher |
| Rail access (intermodal) | BNSF & UP (extensive network) | Class I connections (comparable) |
| USTR vessel surcharge | Applies to most Chinese-built vessels | Applies to most Chinese-built vessels |
| Customs broker (recommended) | $250–$600 per entry | $250–$600 per entry |
The bottom line on cost is that if your goods are going to Oregon, Idaho, or the inland Pacific Northwest, Portland often has a lower total landing cost because it has less drayage. Seattle’s competition among carriers and rail connections usually make it cheaper to ship cargo to Washington state or move it by rail to distribution areas in the Midwest and East Coast.
Carrier Services and Route Frequency
This is where the distance between the two ports is biggest, which is very important for making sure the supply chain works.
The NWSA gets weekly service requests from almost all of the major trans-Pacific carriers, such as Evergreen, Yang Ming, ONE, Hapag-Lloyd, MSC, CMA CGM, COSCO, and others. These carriers work together in vessel-sharing alliances that make sure there is always enough capacity for incoming and outgoing shipments. In 2024, the main Chinese ports for container imports going to the NWSA were Yantian (180,249 TEUs), Shanghai (158,655 TEUs), and Ningbo (126,628 TEUs). Importers who send goods to Seattle have a lot of options for where to combine their Chinese manufacturer freight because of this wide range of origins.
The number of carriers in Portland in early 2026 is much lower. At debut, SM Line is the only company that offers a direct service from China to the OCT on a regular basis. MSC used to run a weekly service between Asia and Portland, but it stopped in 2025 when U.S. taxes made cargo volumes low enough for the carrier to move container slots to ports with more demand. Tim McCarthy, president of OCT, has stated that MSC expects to start up Portland service again in the second quarter of 2026 and has said that other carriers are very interested. The goal is to expand beyond China and South Korea to encompass Japan, Southeast Asia, and the Mediterranean in the future.
Seattle is the clear and immediate choice for importers who need regular, high-frequency service from more than one Chinese port. Portland is a narrative of rebuilding. It has real institutional backing and infrastructure that is getting better, but it is still working to fix the relationships with carriers that were damaged by the 2015 labor conflict and years of operational uncertainty.
Infrastructure and Inland Connectivity
Both ports include on-dock rail yards with Class I railroad connections. This is very important for transferring cargo from the ports to distribution areas in the Midwest or eastern U.S. Seattle is connected to the BNSF and Union Pacific rail networks, which serve hubs from Chicago to Dallas. Portland has similar Class I connections and a unique geographic advantage: the Columbia River Gorge is the only river-grade highway and rail corridor through the Cascade Mountains. This makes Portland a natural distribution gateway for markets in Idaho, eastern Oregon, and the interior Pacific Northwest. Because of this geographical advantage, agricultural items, bulk goods, and furniture move through Portland’s terminals quite quickly.
The OCT at Terminal 6 is 419 acres big and can accept both 20-foot and 40-foot containers. It can also handle breakbulk. The Columbia River channel is kept at a depth of 43 feet, which is deep enough for Panamax-class ships but not as deep as Seattle, which can now handle Neo-Panamax ships up to 16,000 TEUs. Seattle’s post-expansion infrastructure is a big plus for importers who want to ship on the world’s biggest trans-Pacific ships and get the best freight rates based on capacity. The depth limit at Portland doesn’t matter for people transferring regular cargo on regular Panamax services.
The 2025–2026 Tariff Environment and Its Impact on Both Ports
Over the past two years, the tariff environment has been the most important factor changing how Pacific Northwest ports work. Before the U.S.-China trade truce in May 2025, IEEPA duties on Chinese goods were as high as 145%. For 90 days of negotiations, the rates were lowered to 30%. This instability caused big spikes in imports, which were followed by big drops as importers tried to avoid tariff hikes and then pulled back when higher rates were published. The NWSA said that in early 2025, ships were actually coming in more regularly than they did in 2024. However, individual ships were sometimes just 30% full because of canceled bookings. This shows how much uncertainty affects cargo planning.
The port had expected a 30% loss in container shipments in May 2025 for Portland specifically, but the tariff ceasefire slowed the drop. Importers now have to account for several tariff scenarios in their yearly cost estimates at both ports, instead of just assuming that rates would stay the same. The USTR vessel surcharge program, the termination of de minimis for Chinese imports, and the possibility of more IEEPA escalations are all important cost factors that need to be managed ahead of time.
One trend in diversification that is worth keeping an eye on is that both Seattle and Portland are seeing more goods coming from Southeast Asia, especially Vietnam, Indonesia, and Thailand. In 2024, the NWSA handled 184,457 TEUs of cargo from Vietnam. There were already three direct connections between Vietnam and the Pacific Northwest. The NWSA’s rising coverage in Southeast Asia is a real plus for importers who are actively diversifying their supply chains that are heavily reliant on China.
How Topway Shipping Helps You Navigate Both Ports
If you decide that Portland or Seattle is the best place to bring in goods from China, having an experienced logistics partner on the ground in China is what makes the difference between a smooth supply chain and expensive surprises. Topway Shipping, based in Shenzhen, China, has been a professional provider of cross-border e-commerce logistics and freight solutions since 2010. The founding team has more than 15 years of real-world experience in international logistics and customs clearance, with a lot of knowledge about China and the U.S. moving things.
Topway Shipping handles the whole logistical chain, from getting goods from factories in China to origin ports, to storing them overseas, to clearing U.S. customs, and finally delivering them. They provide flexible FCL and LCL ocean freight services from China to major U.S. ports, such as the Port of Portland and the Port of Seattle. This means that Topway may look at real-time routing alternatives for both gateways, see which carriers are currently calling at each port during a certain booking window, and combine LCL cargo for smaller importers who want to keep their shipping costs low.
In real life, Topway’s knowledge of customs clearance is especially useful right now. With de minimis gone for Chinese goods, ISF filing requirements, anti-dumping and countervailing duty exposure, and the new USTR vessel surcharge all making every China import entry more complicated, having a team that proactively manages documentation compliance is a big operational advantage.
The reactivation of the OCT under Harbor Industrial in January 2026 is a great incentive for Oregon-based enterprises that had always routed through Seattle since Portland’s service was too unreliable to rethink their plans. Topway can help you figure out if a Portland-direct route, which has lower drayage costs and less traffic, makes sense for your unique cargo profile and delivery schedule.
Decision Framework: Which Port Is Right for You?
What you ship, where it goes, and how important supply chain reliability is to your organization right now will all affect the proper answer. There is no clear winner; both ports have their own strengths and weaknesses.
Seattle is the better choice if you need the most carrier options, the lowest ocean freight prices because of active market competition, or if you’re sending goods to Washington state or carrying cargo by train across the continental U.S. The NWSA is the best place in the Pacific Northwest for high-volume trans-Pacific trade because of its size and facilities for mega-vessels. The cost is traffic jams. Seattle has had among of the longest vessel delays on the West Coast through 2025, and the high volumes that drive rate competitiveness also make it more likely that there would be bottlenecks amid tariff-driven import surges.
Portland is the better choice if your goods are going to Oregon, Idaho, or the inland Pacific Northwest. You’ll have to deal with fewer carriers, but you’ll have less congestion, faster dwell time, shorter drayage, and a terminal that has stable long-term management for the first time in ten years. The OCT will be relaunched in 2026, which is a big turning point. MSC is anticipated to start service again in the second quarter of 2026, and there are talks about adding other carriers. This means that Portland’s carrier coverage is getting better.
| Your Situation | Recommended Port |
| Need weekly sailings from multiple Chinese ports | Port of Seattle (NWSA) |
| Goods destined primarily for Oregon or Idaho | Port of Portland (OCT) |
| Shipping high volumes, need lowest ocean rates | Port of Seattle (NWSA) |
| Want lower port congestion and predictable dwell time | Port of Portland (OCT) |
| Need Neo-Panamax vessel access for best rates | Port of Seattle (NWSA) |
| Rail distribution to Midwest / East Coast hubs | Both offer on-dock rail; Seattle has more service options |
| Building supply chain redundancy / risk diversification | Route split across both ports as a hedge |
Conclusion
The Port of Portland and the Port of Seattle are both good places for China to bring goods into the Pacific Northwest, although they are better for different types of shippers. Seattle is the main gateway for high-volume trans-Pacific trade in the region. It has the NWSA’s 3.3 million TEU combined traffic, facilities that can handle mega-vessels, and strong relationships with carriers. Portland, which will become the Oregon Container Terminal under Harbor Industrial’s management in 2026, is a smaller, more specialized option that is now more appealing than it has been in the last ten years.
The 2025 tariff problems, the USTR vessel fee program, the end of de minimis for Chinese exports, and the fact that U.S.-China trade policy is still up in the air have all made choosing the right port more critical than ever. The lowest overall landed cost isn’t necessarily the same as the lowest ocean rate. The real costs of bringing goods into the Pacific Northwest include things like congestion, the distance to the drayage, the time spent at the port, the reliability of the carrier, and the speed of customs clearance.
The best approach to make this decision with confidence and maintain it up to date as things change is to work with a logistics partner who knows both ports inside and out, including their current carrier schedules, terminal capabilities, customs clearance details, and cost structures. Topway Shipping is based in Shenzhen and has been shipping goods between China and the U.S. for over 15 years. logistical knowledge, is made to help importers achieve just that.
FAQs
Q: Is the Port of Portland still accepting container shipments from China in 2026?
A: Yes. The Oregon Container Terminal (OCT) is now what Terminal 6 is called. Harbor Industrial Services runs it under a long-term lease that is supported by $40 million in state financing. It currently has direct container service from China and South Korea through SM Line. MSC is set to start up its Asia-Portland service again in the second quarter of 2026.
Q: How does transit time from China compare between Portland and Seattle?
A: The ocean portion to Portland takes around one to two days longer because of the trip down the Columbia River. But Portland’s terminals are much less crowded than Seattle’s, which has typical delays of 6.5 to 7.5 days in 2025. This difference can make overall door-to-door times similar or even faster during busy times.
Q: Is it cheaper to import through Portland or Seattle?
A: It depends on where you’re going. Portland usually has a lower total landing cost for products going to Oregon since the drayage is lower. Seattle’s greater carrier frequency usually leads to better ocean rates that make up for the savings on drayage for cargo going to Washington or rail-forward to distribution locations in the Midwest or East Coast.
Q: What is the USTR vessel surcharge and does it affect both ports?
A: Starting October 14, 2025, the USTR port fee program will charge fees to Chinese-built ships that dock in U.S. ports. Carriers are passing these expenses on to shippers as surcharges because most of the world’s container fleet is built in China. It applies to both Seattle and Portland, so you should include it in your shipping budget no matter which port you pick.
Q: How can Topway Shipping help me decide which port to use?
A: Topway Shipping’s team looks at your cargo profile, the port of origin in China, the final destination in the U.S., the volume, and the delivery time to suggest the cheapest route. They take care of the initial leg of the pickup in China, the booking of ocean freight, the clearance through U.S. customs, and the last-mile delivery to both Portland and Seattle. This means you only have to deal with one company for the whole cargo.
