In 2025, roughly 80% of ecommerce brands saw their costs go up because of US tariff changes. For brands that spent years optimizing around cheap overseas supply chains, the math flipped. The question stopped being “how do we ship for less” and became “how do we ship faster and more reliably without getting wrecked by trade policy.” That shift is why domestic fulfillment hubs, especially in Southern California, are getting busier.
Here’s what’s happening and why it matters for your brand.
Tariffs broke the old cost model
For a decade, the playbook was simple: manufacture overseas as cheaply as possible, accept long lead times, and optimize for unit cost. Tariffs blew that up. When 80% of brands report higher costs from trade policy, the savings from low-cost international supply chains shrink, and the unpredictability becomes its own expense.
So brands are rebalancing. Extensiv’s 2025 benchmark found that 76% of shippers and 71% of 3PL providers are actively moving toward regional or domestic production and fulfillment networks. The priority shifted from pure cost to speed and reliability, because a slightly higher per-unit cost beats inventory stuck on a delayed container while your customers wait.
Why Southern California specifically
If your products still come from overseas, they almost certainly land at the ports of Los Angeles and Long Beach, which handle a huge share of containerized imports into the country. Warehousing near those ports cuts the drayage cost and time of moving inventory anywhere else first.
From a Southern California base, you also reach about 85% of US addresses in 2-day ground transit, while sitting minutes from the Port of Long Beach for imports. That combination, fast import clearance plus fast outbound delivery to the largest consumer market on the West Coast, is hard to beat. We recently cleared a 20-pallet container from Australia through customs and into our Jurupa Valley facility, coordinated end to end, and the inventory never took a detour across the country and back.
Shipping zones are quietly costing you money
Carriers divide the country into zones, and a package that costs $5 to Zone 2 can cost $9 to Zone 8. If your brand sells nationally but ships from a single warehouse on the wrong coast, your customers on the other side wait longer and you pay more on every order.
For a brand selling heavily on the West Coast, a California fulfillment base means most of your orders ship short-zone, which is cheaper and faster. That’s not a small optimization. Fulfillment runs 10% to 15% of revenue for most DTC brands, and shipping is usually the single largest piece of it.
2-day delivery is the new baseline
Amazon trained shoppers to expect 2-day delivery, and now it’s table stakes. Studies show a majority of shoppers abandon a purchase when 2-day delivery isn’t available. Your fulfillment network design, where your inventory sits and which carriers you use, determines whether you can make that promise.
A Southern California node lets you offer fast, affordable delivery to the entire West Coast without paying expedited rates, which protects both your conversion rate and your margin.
What to look for in a fulfillment partner now
The brands handling tariff pressure well aren’t just chasing the lowest pick-and-pack fee. They’re looking for real-time inventory visibility, integration with the platforms they already sell on, the ability to handle DTC, Amazon, and wholesale from one inventory pool, and a partner close to the ports that can flex with volume swings.
We run receiving, storage, pick and pack, FBA prep, B2B fulfillment, and freight coordination out of four Southern California facilities in Jurupa Valley, Lake Forest, Perris, and Commerce. That footprint puts your inventory next to the ports and within fast ground reach of your West Coast customers.
