If you're a seller in Istanbul, Shenzhen, or Milan shipping into Amazon US, your default assumption is probably Los Angeles or Long Beach. That's where the big Asia-to-US containers land. That's where your freight forwarder recommended.
For most international sellers doing under $5M/year in Amazon volume, this is backwards. Here's why Houston quietly wins.
The math on port congestion
Los Angeles and Long Beach move about 20 million TEUs (twenty-foot equivalent units) combined per year. Houston moves about 4 million.
But congestion isn't about volume — it's about volume-to-capacity ratio. LA/LB hit 95% utilization during peak quarters. Containers wait 5–8 days to unload during holiday season. Port of Houston runs around 70% utilization. Peak wait times: 1–2 days.
For a 40' container arriving at peak season:
- LA/LB: 6-day unload wait + 2-day truck coordination = 8 days on the water before your inventory hits a warehouse
- Houston: 1-day unload wait + 1-day truck coordination = 2 days
That 6-day difference is a week of lost Amazon sales for holiday Q4 inventory.
The rent angle
Commercial warehouse rent near LA ports: $1.80–$2.40 per square foot per month (triple net). Near Newark: $1.60–$2.10. Near Port of Houston: $0.85–$1.20.
That's a 40–50% delta on your fixed warehouse cost — whether you run your own warehouse or use a 3PL. At Shipprep, we pass this delta directly into lower per-pallet storage rates ($28/month vs $45–$55/month at coastal 3PLs for equivalent pallet position).
The customs angle
All major US ports have Customs and Border Protection offices. But duty rates, processing times, and broker availability differ.
Houston's Section 321 processing — the de minimis threshold that waives duties on shipments under $800 per recipient — is generally faster than LA. Houston processes ~2 hours, LA processes ~6 hours for equivalent entries. For e-commerce sellers shipping direct-to-consumer via Section 321 from China, this compounds across thousands of parcels.
The 2-day ground radius
From LA, 2-day ground shipping reaches about 60% of US population. From Newark, about 70%. From Houston, about 96%.
This is the killer stat most sellers don't run. If you're shipping to Amazon FCs, this doesn't matter (Amazon moves your inventory internally). But if you're doing direct-to-consumer Shopify orders or Seller Fulfilled Prime, your 2-day ground radius determines your shipping costs.
From a Houston warehouse, you can hit 96% of US customers in 2 business days by ground. That means you don't pay for 2-day air shipping on the majority of your orders — you pay for ground, and customers get it in 2 days anyway.
When LA still makes sense
To be fair, LA is the right answer for some sellers:
- If your volume justifies a dedicated 500k+ sqft warehouse (50+ FTE operations)
- If 70%+ of your customers are California/Pacific Northwest
- If you're running cold chain operations (more specialized 3PLs in LA)
- If you need container transloading as a standalone service
For everyone else — especially international sellers in the 100–5000 orders/month range — Houston is the quieter, cheaper, less-congested choice.
What to do about it
If you're currently shipping containers to LA and using a CA-based 3PL, run this math:
- Storage cost delta — your current per-pallet rate × 12 months × 40–50% = annual savings
- Shipping cost delta — % of orders currently going ground to East Coast × additional 2-day air premium = annual savings
- Speed delta — 4–6 extra days of saleable inventory during Q4 peak
For a seller doing 500–1000 orders/month with 20 pallets of storage, the total annual savings typically lands between $8,000–$18,000 — plus the faster Q4 inventory velocity.
The main reason more sellers don't do this isn't economics. It's inertia. They signed with an LA 3PL on day one, and switching feels expensive. But switching 3PLs is usually 2–3 weeks of overlap time and zero service interruption.
