• Warehousing and storage17,241 jobs in 2025, 0.91% of the US total. Forklift tines split decks and chip corners. A racking change retires one style at once. Strays arrive on inbound trailers from shippers who use pooled pallets, and sit in the yard until someone asks whose they are. Check the strays first. Then separate the rackables, which are usually PP, from the nestables, which are usually HDPE. Describe each stack as its own line. In a pile from here, photograph the yard stacks, from the dock side.
• Food manufacturing5,802 jobs in 2025, 0.33% of the US total. Sanitation audits remove cracked or stained pallets. A change of packaging line retires a colour-coded set. Pallets that held ingredients with strong odours or oils are culled early. Hygienic 48 x 40 and 40 x 48 pallets in HDPE or PP, often with closed decks and colour-coding by zone. Some are listed as food safe but not approved for direct food contact. In a pile from here, photograph the deck surface and any staining.
• Grocery and related product wholesale2,331 jobs in 2025, 0.28% of the US total. High volume and many inbound shippers. Strays collect at the back of the yard. Sets retire when a retailer changes its pallet standard. Sort marked from unmarked first. Count the unmarked by style. This industry is where the ownership check matters most. In a pile from here, photograph every mark, logo and RFID bump.
• Dairy product manufacturing1,302 jobs in 2025, 0.77% of the US total. Say if pallets were washed with strong chemicals. Say if any are coloured to mark zones.
