The pork belly is one of the more economically interesting primals because of its concentrated end use. Roughly 16 to 21 percent of carcass weight, almost all of it becomes bacon. The primal is sold in weight bands (broadly grouped as light, medium, and heavy, with specific cutoff weights varying by packer and customer) because thicker bellies render bacon differently than thinner bellies and the slicing operations care about the difference. Belly is famously the most volatile primal on the pork carcass. Bacon demand is persistently strong but with notable seasonal swings (summer BLT pulls, fall holiday programs) and large inventory dynamics in cold storage that periodically work through the market. When cold storage stocks run high, bellies trade soft until inventory clears; when stocks run low and a feature window approaches, bellies can run sharply higher in a matter of weeks. Buyers who track belly without tracking cold storage stocks are routinely caught on the wrong side of these moves. Belly prints daily in the USDA AMS National Daily Pork Carcass Cutout report (LM_PK602), with the various weight-band lines breaking out separately. Volume on belly runs thinner than the cutout-wide average because of the band fragmentation, so individual prints carry more noise than headline cutout reads.
