Port Congestion at LA/Long Beach: 3 Routing Backup Plans Every Shipper Should Pre-Book

Table of Contents

Introduction

The Ports of Los Angeles and Long Beach together are the busiest container gateway in the Western Hemisphere, carrying approximately one-third of all U.S. international trade. Shippers have for years considered them the default, almost the only, entry point for China-origin goods headed for American consumers and distribution centers. That presumption has proven to be expensively harmful.

Even as late as early 2026, when POLB statistics and third-party vessel trackers like as GoComet and Portcast show median congestion delays had reduced to only 3 days and average truck queue durations a fast 13 minutes, the underlying dangers that have repeatedly paralysed this corridor have not gone away. Labour negotiations, empty sailings, tariff-induced traffic spikes and regulatory compliance bottlenecks may turn a smooth port into a crisis in weeks. Shippers who learned this lesson during the 2021-2022 backlog, when more than 70 vessels waited offshore and an estimated $238 billion of freight lay idle in San Pedro Bay, can’t afford to relearn it again.

This article outlines three precise route backup plans that all shippers of big or heavy freight from China to the United States should pre-book before the next disruption hits. These are not hypothetical options. They work routes with real transit data, cost trade-offs, and different advantages depending on cargo kind, destination and urgency. We also look at how freight partners such as Topway Shipping can be a linchpin in your contingency plan when your principal path goes sideways.

Why “Wait and See” Is No Longer a Strategy

Most supply chain teams considered the 2021-2022 congestion situation a once-in-a-generation oddity. It wasn’t. From mid-May to early July 2025, carriers removed almost 40 percent of sailings from U.S. West Coast routes in reaction to tariff-driven demand collapse, with importers scurrying for space Volumes bounced up almost overnight with the May 2025 announcement of a 90-day tariff ceasefire between the U.S. and China, but the space-crunching resumed sailings couldn’t keep pace with the surge in bookings, resulting in a second wave of space limitations in the same quarter.

The data now captures that structural transformation. LA and Long Beach are each facing year-on-year volume losses of some 1.5% in the first half of 2026, while Houston continues to grow on the basis of improved ship canal capacity. Savannah processed 5.7 million TEUs in 2025, with year-over-year rise of 2.6%. The market is not walking away from the West Coast, but the more resilient supply chains are no longer running all of their volumes through the West Coast.

But beyond just changes in the volume, the tariff landscape has added an extra layer of planning difficulty that didn’t present three years before. China to U.S. Bookings for the first quarter of 2026 are about 30% lower than for the same period in 2024 as importers adapt to duties that now surpass 100% in several product categories. Supreme Court proceedings over the legal basis for such levies are adding another degree of uncertainty. In this scenario, a shipper who has pre-negotiated back-up routing contracts and pre-cleared customs papers for different ports is not being paranoid, they are being professional.

Understanding the Real Cost of LA/Long Beach Disruption

Most logistics teams who estimate the cost of a congestion event focus on demurrage. And that’s merely the start. For 2025 peak interruption periods, container dwell times at LA averaged 10-12 days compared with less than 4 days at Savannah and Houston during the same period. An extra week of flow of 1,000 containers per month costs $1.4 million in direct penalty costs at average demurrage rates of $200 per container per day – not including detention charges on the trucking side, airfreight premiums for expedited replenishment or the downstream revenue loss from retail stockouts.

And it’s even worse for shippers of big goods – the group that includes furniture, fitness equipment, appliances, industrial machinery and commercial vehicles. They also handle oversize shipments, assign cranes for oversize shipments, and appointments in advance at the destination with the carriers. When a port goes down these appointments fall apart one after the other. A container lying at a berth for 14 days because it can’t take scheduled drayage costs a lot more than the demurrage line item shows.

The table below compares important operational parameters across the four major gateway alternatives accessible to shippers originating in China in mid-2026.

Port Gateway	2025 Volume (TEUs)	Avg. Dwell Time (2026)	Inland Rail Access	Oversized Cargo Suitability
LA / Long Beach	10.1M (combined)	4–5 days	Strong to Midwest/Southwest	High — deep established network
Port of Savannah	5.7M	2–3 days	Strong to Southeast/Midwest	Moderate — growing capability
Port of Virginia	Record 2025	2–3 days	Strong — 55ft deep channel	High — mega-vessel capable
Port of Houston	+43.9% vs 2019	2–3 days	Strong to South/Central US	High — energy & industrial focus

Backup Plan 1 — The East Coast All-Water Route via Panama Canal

Chinese ports to US all-water route The most entrenched alternative to the West Coast route is East Coast ports via the Panama Canal. Major Chinese export centers such as Shanghai, Ningbo and Guangzhou are around 28 to 35 days by transit to Savannah or Virginia, depending on the carrier service and port rotation. That’s longer than the 12 to 15 days to LA/Long Beach, but the cost differential has reduced dramatically in 2026.

Asia to U.S. The West Coast saw rate growth of around 33-37% on the basis of the blank sailing capacity withdrawal, while the trade lanes through Panama, with more balanced supply and demand dynamics, traded at somewhat lower rates for the same size container. For non-time-sensitive cargo, which includes most furniture, home appliances and industrial equipment, this cost benefit usually more than compensates for the longer transit times.

“The Port of Virginia is especially well-suited for oversized goods. Its canal, 55 feet deep, can handle fully loaded mega-vessels, and the port has made major investments in intermodal rail connections that easily reach interior manufacturing and distribution centers. The Port of Savannah has strong rail connections to Atlanta, Charlotte, Memphis and significant Midwest cities – routes C.H. Robinson and other larger 3PLs are consistently among the best performing intermodal routes in the country.

Shippers here need to pre-book not merely space in the water. To make this route work during a West Coast disruption, you have to have pre-arranged chassis pools at the East Coast port, pre-cleared customs bonds with East Coast brokers, and trucking agreements set up for last-mile delivery from East Coast distribution hubs. Shippers that pre-assemble these items can reroute a shipment in 72 hours. Those who start from scratch in a crisis normally lose two to three weeks.

Key considerations for Backup Plan 1

Transit time from major Chinese ports to most East Coast destination terminals is 28-35 days, or about two weeks longer than West Coast routing. It costs far less to ship inland freight to destinations in the Midwest and Southeast from Savannah or Virginia than it does from LA on intermodal rail—one estimate pegged the savings at almost $1,500 per container for cargo headed to Atlanta. The Panama Canal continues to have its own operational uncertainty, including as water level constraints that have historically impacted draft limitations during dry seasons. Book your ocean service contract and your inland logistics together, to avoid the usual failure mode of arriving at the port without verified onwards conveyance.

Backup Plan 2 — Gulf Coast Diversification via Houston

Port Houston has grown 43.9% in volume over 2019, due in part to ship canal improvements that now allow larger vessels, and an unmatched logistics network that serves the energy, petrochemical and manufacturing sectors of Texas and the South Central U.S. For shippers whose final destination is within the Texas corridor — or whose supply chains have nearshored any production to Mexico — Houston is more than just a backup, but in many cases the structurally superior primary gateway.

Transit time profile for China-to-Houston all-water services is generally similar to routing through the East Coast — about 30 to 38 days depending on carrier and vessel rotation. The difference in Houston is the inland cost calculation. Shipping a container to a Texas distribution hub from Houston or from any West Coast option is a fraction of the cost, and the port’s connections to Mexico and Latin America provide flexibility to shippers who are managing cross-border supply chains under the current U.S.-Mexico trade architecture. Trade between the U.S. and Mexico hit an all-time high of $872.83 billion in 2025, with Mexico maintaining its spot as the U.S.’s top trading partner for the third straight year – and Houston lies smack in the middle of that logistical map.

Houston’s infrastructure profile is solid, particularly with regards to big and heavy goods. The port can handle large volumes of industrial machinery, commercial equipment and energy sector cargo, and has the availability of heavy-lift cranes and customs expertise to manage complex cargo classifications. If you’re a shipper of things like massage chairs, treadmills, industrial refrigeration equipment or commercial cooking appliances – the kind of big-ticket consumer products coming across the Pacific in ever-greater numbers – Houston’s receiving infrastructure will be genuinely competitive with West Coast options.

Beforehand, service contracts with carriers that provide China-Gulf services must be established to activate Houston as a backup, and Houston’s customs infrastructure must be registered, along with chassis and drayage networks in the region. The good news is that Gulf Coast logistical capacity is less constrained than West Coast capacity during peak disruption periods, exactly because it is not the key concentration point for trans-Pacific volume.”

Backup Plan 3 — Rail Intermodal via Mexico Border Crossings

The third, and arguably more essential, backup option is less discussed: shipping cargo from China by water to a Pacific port in Mexico, usually Manzanillo or Lazaro Cardenas, and then transferring it north by train across the U.S.-Mexico border. This multimodal route is logistically more involved, but can be faster than an all-water East Coast routing, and completely avoids the capacity concentration at LA/Long Beach.

Manzanillo is Mexico’s largest container port and handles large trans-Pacific volumes. Further down the Pacific coast of the state of Michoacan, Lazaro Cardenas has seen major infrastructure investment and is expressly built as an alternate Pacific entry point for cargo destined for the interior of the U.S. Kansas City Southern (now CPKC) rail links from either port move containers north through the border crossing at Laredo or other Texas entry points to U.S. distribution centers in the Midwest and South in transit times that can be competitive with an all-West Coast routing when LA congestion is severe.

Transit time from Chinese ports to Manzanillo is approximately 20 to 25 days plus 5 to 8 days of rail movement to U.S. inland destinations; this equates to a total door-to-distribution-center window similar to a West Coast ocean move plus drayage in Los Angeles during a congested period. Cost profile varies by individual origin-destination pair, but the route has gained substantial shipper attention since it avoids the labour risk and concentration of congestion in the Southern California port complex.

There are some important issues here so you will need to prepare in advance. Customs procedures at the U.S.-Mexico border are not the same as for ocean port clearance, and documentation requirements, carrier liability frameworks and cargo inspection methods are different. Additional permits are required for shippers with big or heavy loads for cross-border movement by truck or rail. These are not insurmountable barriers, but they are not things you want to be figuring out for the first time in a crisis. Customs bonds, carrier relationships and compliance documents for goods into Mexico don’t happen overnight – it’s preliminary work that only pays off when you need it.

The Comparison: Choosing Your Backup Based on Cargo and Destination

There is no one backup route that works best for all. The best solution relies on the character of your goods, its eventual destination, your willingness to trade off transit time and cost, and the precise nature of the disruption you are facing. The matrix below offers a structure for thinking through the decision.

Scenario	Recommended Backup	Key Advantage	Pre-Book Lead Time
Southeast US destination, flexible timing	East Coast (Savannah)	Lower inland cost, strong rail	4-6 weeks
Texas/South Central US destination	Houston Gulf Coast	Best inland cost, Mexico connectivity	4-6 weeks
Midwest US, moderate time pressure	East Coast (Virginia)	Deep channel, strong intermodal	4-6 weeks
High volume, cost-sensitive, non-perishable	Mexico Rail Intermodal	Avoids West Coast entirely	8-12 weeks
Time-sensitive, high-value goods	Air freight or West Coast premium space	Speed priority over cost	Immediate booking
Oversized/heavy freight, any disruption	Consult specialized forwarder (e.g. Topway Shipping)	Specialized handling expertise	Ongoing relationship

Where Topway Shipping Fits Into Your Contingency Strategy

For shippers of big and heavy goods – the category that conventional forwarders often handle badly – the choice of logistics partner is as important as the choice of route. Established in 2010, Topway Shipping (Shenzhen Topway International Freight Co., Ltd.) is headquartered in Shenzhen and was created to meet the special needs of shipping huge, heavy and odd dimension goods from China to the global market.

Topway Shipping has been a competent provider of cross-border e-commerce logistics solutions since 2010. Its founding team has more than 15 years expertise in international logistics and customs clearing, specialising in China to U.S. & shipping from China to Europe . The company’s service scope covers the full logistics chain, including first-leg pickup from the manufacturer or warehouse, export clearance in China, ocean freight (FCL and LCL), overseas warehousing, customs clearance at the destination country, and last-mile delivery including scheduled appointment delivery for large items.

What makes Topway particularly relevant to the backup routing issue is its characterisation of the cargo it manages operationally. The company’s “oversized” category includes single products weighing 8 metric tonnes or less, with any one dimension up to 8 meters and height up to 2.57 meters, parameters that are much above what normal parcel and general cargo carriers can handle. Operational proficiency on this end of the size scale is a crucial distinction for shippers of commercial furniture, exercise equipment, industrial appliances, massage chairs, electric vehicles or speciality machinery.

In terms of routing, Topway offers ocean freight services from China to 25 European countries on DDP (Delivered Duty Paid) basis and U.S. market services for ocean freight, air freight, foreign warehousing and FBA (Fulfilment by Amazon) preparation. Its China-Europe rail service across the existing cross-continental lines provides an alternative routing for time-sensitive, but cost-constrained shipments. The company’s patented logistics management system offers full insight into shipments, a critical capability during disruptions when shippers need to know precisely where their cargo is and what options exist to expedite or reroute it.

A shipper who has built a working relationship with Topway Shipping is in a better place than one who starts calling when a West Coast interruption is happening, when it comes to backup routing. And Topway’s operational infrastructure, its carrier ties, warehouse presence and customs clearance teams in several U.S. and European markets can’t be set up overnight. The time to build such ties is before you desperately need them.

Building Your Pre-Booking Framework

The ports of LA and Long Beach are not going away and for many shippers are still the right primary gateway. However, the 2026 supply chain climate, with tariff volatility, carrier blank sailing behaviour, regulatory complexity and the structural transfer of cargo to East and Gulf Coast ports, makes single-point West Coast dependence a risk more harder to justify.

The three backup routes detailed in this article, all-water East Coast via Panama, Gulf Coast diversification via Houston, and rail intermodal via Mexico, all serve different cargo and destination profiles. All of which need pre-investment: pre-booked carrier relationships, pre-established customs infrastructure and pre-briefed manufacturing partners. That pre-investment is exactly what separates supply chains that manage disruptions from supply chains that are managed by them.

The complexity of backup routing is above average for shippers of big and heavy cargo and the implications of disruption are more severe. The contingency plan becomes a reality through execution capability. Partnering with a specialist like Topway Shipping – with deep operational expertise in large-item international logistics, established carrier relationships across multiple routing corridors and a proprietary visibility platform. That’s the most actionable thing most logistics teams can do right now: build that relationship before the next upheaval hits.

Conclusion

FAQs

Q: How long does it take to activate an East Coast backup route if LA suddenly congests?

A: If you have pre-booking and documentation already in place, rerouting ocean cargo in transit or rerouting upcoming reservations to East Coast ports generally takes 48-72 hours for in-transit cargo and 1-2 weeks for factory-level modifications. The same process takes at least 3-6 weeks without pre-existing partnerships.

Q: Is the all-water East Coast route via Panama Canal significantly more expensive than LA/Long Beach?

A: By mid-2026, the differential between the rates has narrowed considerably. West Coast rates were up 33-37% in May 2026 due to blank sailings, but East Coast rates were fairly unchanged. For Southeast or Midwest destinations, the reduced inland charge from Savannah or Virginia can more than cover the higher ocean rate.

Q: What types of oversized cargo can Topway Shipping handle on alternative routes?

A: What is the maximum weight and size of the cargo? A: Topway Shipping is able to carry cargo up to 8 metric tonnes per piece and up to 8 meters long and 2.57 meters high each piece. Those include such categories as business furniture, fitness equipment, home appliances, massage chairs, electric scooters, speciality machinery, etc., for either ocean or rail routing.

Q: Does the Mexico rail intermodal route require separate customs clearance?

A: Yes. Cargo going via Mexico requires Mexican customs documentation and U.S. import clearance at the border crossing point. This means additional upfront compliance preparation time but does not significantly affect transit time once the documentation framework is in place.

Q: How far in advance should shippers pre-book East Coast or Gulf Coast backup capacity?

A: You can develop framework agreements and carrier connections without any immediate volume commitments therefore there is no minimum lead time for the relationship itself. For specific sailings in a backup scenario, East Coast and Gulf Coast carriers often require 2-4 weeks booking advance time compared to the 1-2 weeks typical for West Coast routes during regular periods.
