Import from China to California
California is the primary gateway for US imports from China. The twin ports of Los Angeles and Long Beach handle nearly 40% of all inbound US container traffic. California importers benefit from the fastest trans-Pacific sea freight transit times from China, massive warehousing ecosystems in the Inland Empire, and direct rail connections to the rest of the continent.
The San Pedro Bay Port Complex (LA/Long Beach) is the largest seaport complex in the Western Hemisphere, processing over 19 million TEUs annually.

How to use this California import guide
California guides provide tactical route planning for importers shipping from China. This page brings those pieces together for importers evaluating shipments into California. It highlights local infrastructure, the products and industries most exposed to China sourcing, and the US-specific cost logic that matters once Section 301 tariffs, MPF, and HMF are factored in.
The most important local question is not just whether goods can reach California, but how they reach it most efficiently. In practice, that means matching the shipment to 3 major port or ICD options, the buyer's warehouse location, the urgency of the inventory, and the product class being imported. A route that looks cheap at the port level can become slower or more expensive after rail movement, ICD handling, or inland delivery.
For importers in or around California, the industries that usually shape demand are Technology & Hardware, Apparel & Fashion, Consumer Electronics, E-commerce & FBA, Automotive & EV. The corresponding China-sourced categories often include Semiconductors & PC components, Consumer electronics & displays, Apparel & textiles, Automotive parts, Toys & sports equipment.
What to verify before cargo is booked
Before booking a shipment into California, confirm the HTS classification, Section 301 applicability, and the last-mile delivery plan. US imports are sensitive to documentation quality because duties directly depend on the declared HTS code. Unlike VAT systems, US duties are a sunk cost and cannot be recovered via input tax credits.
Importers want to know how the route actually works: which infrastructure is closest, when air freight makes sense, and where timing risk appears. You can use the calculators on this page to estimate your landed cost, and then confirm live rules with official sources like CBP - Basic Importing and Exporting, Harmonized Tariff Schedule, CBP - Merchandise Processing Fee (MPF).
Official US Customs Sources
Use these government references to confirm the current US Customs and Border Protection (CBP) rules that matter when routing cargo into California.
