75+ Manufacturing Capacity Utilization Statistics for 2025-2026

National Manufacturing Capacity Utilization

The Federal Reserve's G.17 release is the benchmark source for US industrial production, manufacturing output, factory capacity, and capacity utilization. When utilization is high, plants are closer to full load. That can mean overtime, longer quoted lead times, tighter scheduling windows, and more pressure to invest in equipment. When utilization is low, the signal is different: spare capacity exists, but that doesn't always mean the right machine, the right skilled operator, or the right certification is available.

The broad 2026 reading is not a boom signal. Manufacturing utilization was below its long-run average, and output remained slightly under its December 2019 level. That matters for owners and marketing teams. A plant can be busy in one cell and still underutilized across the building. Sector data gives you the better read.

Manufacturing Capacity Utilization by Sector

Sector-level utilization is where the data becomes useful for quoting and sales planning. A general "manufacturing is slow" headline doesn't help a job shop decide whether to chase aerospace brackets, electrical cabinets, automotive stampings, or pump components. The spread is wide. Petroleum and coal products ran near 90% utilization in March 2026, while motor vehicles and parts sat below 65%.

Two takeaways jump out. First, the tightest sectors are not always the ones getting the most media attention. Electrical equipment and petroleum products were far above the manufacturing average. Second, transportation equipment split hard. Aerospace utilization improved, while motor vehicles and parts remained soft. If you're building a sales list, don't treat transportation as one market.

High-Tech and Semiconductor Capacity Data

High-tech manufacturing is the odd case in this dataset. Output and capacity expanded quickly, but utilization did not look tight in March 2026. That combination usually means new capacity came online faster than near-term production absorbed it. For suppliers, it means the headline growth is real, but timing matters. A fab expansion can create years of tooling, automation, HVAC, power, and precision component work before utilization ever looks full.

Production Index and Capacity Growth Benchmarks

Capacity utilization is a ratio. You need both sides of the ratio to read it correctly. If output rises but capacity rises faster, utilization can fall. If output is flat but a weaker plant base exits, utilization can rise. That is why the Federal Reserve publishes industrial production, capacity, and utilization together.

Historical Highs, Lows, and Cycle Signals

The useful question isn't only "what is utilization today?" It is "how unusual is this reading?" Manufacturing's long-run average sits around the high 70s. A move above the mid 80s usually feels tight on the floor. A move into the 60s usually means the order book has a problem, except in sectors that are structurally changing or absorbing new capacity.

Stage-of-Process Capacity Utilization

Stage-of-process data helps separate raw material and upstream pressure from final assembly conditions. Crude processing ran hotter than finished processing in March 2026. That gap matters for manufacturers buying castings, forgings, resin, sheet, plate, or other inputs. A plant can have open assembly labor and still wait on upstream material.

How Manufacturers Should Use This Data

Capacity utilization is not a sales forecast by itself. It is a pressure gauge. Use it with your RFQ volume, backlog, win rate, quote-to-close time, and margin data. If your target sector is running hot and your quote volume is weak, you may have a visibility problem. If your target sector is running cold and your pipeline is full of low-margin work, you may be quoting into a buyer's market.

For marketing teams, this resource is also a positioning tool. A supplier selling into aerospace can talk about capacity strain and recovering output. A supplier selling into automotive should be more careful, because buyers may be pushing price. A shop selling maintenance, automation, or throughput projects can use utilization data to frame the cost of constrained capacity, especially in sectors above 80%.

Methodology Notes for Capacity Utilization Data

The Federal Reserve Board, part of the Board of Governors of the Federal Reserve System, publishes the G.17 industrial production and capacity utilization release as seasonally adjusted economic data. FRED, maintained by the Federal Reserve Bank of St. Louis, republishes key United States capacity utilization and US capacity utilization series for researchers who want chartable data. In this report, capacity utilization means the utilization rate or operating rate for a given industry compared with estimated sustainable capacity. The capacity utilization rate is shown as a percentage point measure, so a move from 75% to 76% is a one percentage point increase, not a 1% increase.

The Federal Reserve Board's capacity indexes attempt to capture the greatest level of output that a plant or industrial sector can sustain under a realistic work schedule, not a one-day maximum. That is why capacity indexes, industrial production, real output, manufacturing output, and capacity utilization for manufacturing need to be read together. The North American Industry Classification System, or NAICS, is used for manufacturing industries including durable goods, nondurable manufacturing, motor vehicles and parts, petroleum and coal products, plastics and rubber products, and aerospace and miscellaneous transportation equipment.

The same release also covers utility, electric and gas utilities, mining, the operating rate for mining, the operating rate for utilities, utilization rates for mining, rates for mining and utilities, total industrial production, the index for business equipment, industrial and other equipment, output of consumer goods, output of primary metals, and growth in the output of major market groups. We keep those terms here because they explain how manufacturing activity fits inside the broader U.S. industrial production and capacity utilization system. Source
