West Coast Inventory Placement: Why Stock Near the LA Ports
This guide is for ecommerce and import brands deciding where to keep their inventory. It explains why many brands hold stock on the West Coast near the Los Angeles ports, how to tell from your own order data whether it makes sense for you, and how to split inventory without running out.
What “inventory placement” means
Inventory placement is the decision about which warehouse holds how much of each product. A small brand often ships everything from one building. As order volume grows, the question changes. Where do my customers live? Where does my product arrive? How far does each order travel?
West Coast inventory placement means keeping some or all of your stock in a West Coast warehouse, usually in Southern California, close to the ports where most Asian imports land.
Why brands keep stock near the LA ports
1. Many customers are already in the West
The West is the second-largest region of the country. The 2020 Census counted about 78.6 million people there, close to a quarter of the U.S. population, and California is the most populous state. If your orders follow population, a large share of them ship to West Coast addresses.
2. Imports land here first
The Ports of Los Angeles and Long Beach sit side by side on San Pedro Bay and form the busiest container port complex in the country. When your product comes in by ocean from Asia, it is already in Southern California the day it clears. Stocking it nearby means you can start selling sooner, instead of waiting for another long truck or rail move before the first order ships.
3. Distance drives parcel cost and delivery days
Parcel carriers price ground shipping by zone, and zones are based on the distance between the origin ZIP code and the destination ZIP code. An order shipped across the street is a low zone. An order shipped coast to coast is the highest zone in the lower 48 states. Higher zones usually cost more and take more days in transit. When a warehouse sits closer to the customer, the same order often ships in a lower zone and arrives sooner.
Your carrier’s zone chart and transit map are the best way to see this for your own ZIP codes. Enter a West Coast origin and an East Coast origin, then compare the zones and days to your top customer ZIP codes.
One warehouse or two? Common setups compared
| Setup | Works well when | Watch out for |
|---|---|---|
| One West Coast warehouse | Most product arrives through the LA ports, and a large share of customers are in the West or the order volume is still modest. | Longer delivery times and higher zones for East Coast orders. |
| One central or East Coast warehouse | Most customers are in the East or Midwest, or product arrives through East or Gulf Coast ports. | Extra inland freight before inventory is ready to sell, if goods land on the West Coast. |
| Two warehouses, one on each side | Volume is high enough to keep both sites stocked, and faster delivery matters to your customers or marketplaces. | More inventory tied up, more SKUs to manage, and stockouts if one site runs low. |
There is no single right answer. The best setup depends on where your orders go, where your product lands and how many units you sell.
How to decide with your own order data
- Pull your ship-to data. Export 6 to 12 months of orders with the ship-to ZIP code or state. Include a peak season if you have one.
- Group orders by region. Sort them into West, Mountain, Central and East, or use the carrier’s zone from a test origin. Note the share of orders in each group.
- Compare zones from two origins. Using your carrier’s zone chart, check the zone from a Los Angeles ZIP and from a central or East Coast ZIP for your top destinations.
- Price the difference. Run a sample of real orders through your carrier rates from both origins. Look at the total cost, not just the average.
- Add the inbound side. If your product arrives through the LA ports, add the cost and days of moving it inland to the second site.
- Check your stock depth. Splitting inventory only works if you have enough units of each SKU to keep both sites in stock. Slow movers often stay in one place.
How much stock to place on the West Coast
A simple starting point is to place stock in proportion to demand. If about 35% of your orders ship to the West, start with roughly that share of your fast-moving SKUs in your West Coast warehouse. Then add safety stock based on how long a refill takes.
- Place fast movers in every site you use. Keep slow movers in one site.
- Set a reorder point for each SKU in each site, not just a total.
- Count the days a refill takes, from the port or from your other warehouse.
- Review the split every quarter and before peak season.
- Make sure your store or order system routes each order to the right site.
- Track lots and dates if your products have them, so both sites ship oldest stock first.
Splitting a container at the port
Brands with two sites do not always need to send every container to one place first. A common approach is to unload a container near the ports, keep the share meant for West Coast customers, and send the rest inland on a truck. This is where cross-docking and transloading help. Freight is sorted at the dock and reloaded onto outbound trucks with little time in storage.
The West Coast share can then go into pallet storage as reserve stock, with pick locations refilled as orders come in.
When West Coast stock may not be worth it
- Nearly all of your customers are on the East Coast, and your product lands at an East Coast port.
- Your volume is low, and splitting stock would leave too few units in each site.
- Your customers care more about price than delivery speed, and the zone savings are small.
- You sell many slow-moving SKUs that would sit in two places.
In these cases, one well-placed warehouse is usually simpler and cheaper. Revisit the decision as your order map changes.

Frequently asked questions
Do I need a warehouse on both coasts?
Not always. Two sites make sense when you have enough volume to keep both stocked and faster delivery matters to your customers. Many brands start with one site near where their product lands and add a second site when the order data supports it.
Why is shipping from California to the East Coast more expensive?
Parcel carriers price ground shipping by zone, based on the distance between the origin and destination ZIP codes. Coast-to-coast orders fall in the highest zone in the lower 48 states, so they usually cost more and take longer than regional orders.
Can I split one container between two warehouses?
Yes. A warehouse near the port can unload the container, keep part of it for West Coast orders and reload the rest onto a truck going inland. This is called transloading.
How far is Vernon from the Los Angeles ports?
About 20 miles. Vernon is an industrial city just south of downtown Los Angeles, a direct run up the I-710 from the Ports of Los Angeles and Long Beach.
