Corrugated boxes shipped to California
California is the largest box market in the country by almost any measure. It had 236,923 warehousing jobs in 2025, 12.5 percent of the US total, and 166,660 in food manufacturing. San Bernardino and Riverside counties together held more than 118,000 warehousing jobs.
Who orders boxes in California
Three kinds of buyer write to us from California. Inland Empire and Central Valley distribution buildings want stock RSC sizes by the pallet. Growers, packers and food plants want produce cartons and cases in season; fruit and vegetable preserving alone employed 27,518 people. And shippers near the San Pedro Bay ports want heavy double and triple wall for export. Beverage manufacturing, 63,604 jobs, is the industry most concentrated here compared with the rest of the country.
Delivery and freight
California also holds the most refrigerated warehouse space of any state, 400 million cubic feet in October 2025, which matters when boxes will sit cold. We quote freight to the delivery ZIP, whether that is a dock in Ontario or a packing shed outside Fresno.

Worth knowing in California
Coastal fog and inland heat pull board in opposite directions, so where the boxes are stored matters as much as where they are used. Cartons kept in a Salinas cooler, a Stockton cross-dock and a Riverside fulfilment mezzanine age differently. Growers also face tight harvest windows: berries, grapes, almonds and citrus each peak in their own months, and a shed that runs short on cartons mid-pick loses fruit. Ordering the season's flats before the first pick, and storing them dry, avoids that.
