New Orders Growing; Production Growing; Employment Growing; Supplier Deliveries Slowing Raw Materials Inventories Contracting; Customers' Inventories Too Low; Prices Increasing; Imports Growing; Exports Growing

TEMPE, Ariz., Oct. 1, 2026 /PRNewswire/ -- Economic activity in the manufacturing sector expanded in September for the ninth consecutive month, say the nation's supply executives in the latest ISM® Manufacturing PMI® Report.

The report was issued today by Susan Spence, MBA, Chair of the Institute for Supply Management® (ISM®) Manufacturing Business Survey Committee.

"The Manufacturing PMI® registered 54.5 percent in September, 0.1 percentage point below the August figure of 54.6 percent. The overall economy continued in expansion for the 23rd month in a row. (A Manufacturing PMI® above 47.5 percent, over a period of time, generally indicates an expansion of the overall economy.) The New Orders Index expanded for the ninth consecutive month after four straight readings in contraction, registering 55.3 percent, up 1.6 percentage points compared to August's figure of 53.7 percent. The September reading of the Production Index (56.7 percent) is 1.6 percentage points lower than the 58.3 percent recorded in August. The Prices Index remained in expansion (or 'increasing' territory), registering 77.9 percent, a notable increase of 6.8 percentage points compared to August's reading of 71.1 percent. The Backlog of Orders Index registered 56.4 percent, up 4.6 percentage points compared to the 51.8 percent recorded in August. The Employment Index reading of 52.7 percent is up 1.5 percentage points from August's figure of 51.2 percent," says Spence.

"The Supplier Deliveries Index indicated slowing performance for the 10th month in a row after one month in 'faster' territory. The reading of 59 percent is down 0.3 percentage point from its August reading of 59.3 percent. (Supplier Deliveries is the only ISM® PMI® Reports index that is inversed; a reading of above 50 percent indicates slower deliveries, which is typical as the economy improves and customer demand increases.)

"The Inventories Index registered 48.6 percent, down 2 percentage points compared to August's reading of 50.6 percent. The Customers' Inventories Index reading of 41.6 percent is 1.2 percentage points lower compared to the 42.8 percent recorded in August.

"The New Export Orders Index lost 2.3 percentage points in September for a reading of 50.9 percent versus 53.2 percent in August. The Imports Index registered 51 percent, a decrease of 1.5 percentage points compared to August's reading of 52.5 percent."

Spence continues, "In September, U.S. manufacturing activity remained in expansion territory. Of the five subindexes that make up the PMI®, only New Orders and Employment grew faster than the previous month. In September, 40 percent of the comments were positive and 60 percent negative, with a 1-to-1.6 ratio of positive to negative sentiment. Among negative comments, pricing volatility was mentioned in 46 percent, tariffs 34 percent, the Iran war 30 percent and increasing lead times 21 percent; most comments mentioned multiple factors.

"In September, three of four demand indicators (the New Orders, Backlog of Orders and New Export Orders indexes) remained in expansion, and the Customers' Inventories Index remained in 'too low' territory, contracting at a faster rate. A 'too low' status for the Customers' Inventories Index is usually considered positive for future production.

"Regarding output, the Production Index expanded for the 11th month in a row, with the positive-to-negative comment ratio dropping again in September (1.6 positive comments for every negative one, compared to a 2.2-to-1 ratio in August and 3.3-to-1 in July). The Employment Index remained in expansion and gained 1.5 percentage points. The positive-to-negative comments ratio on Employment was 1.5-to-1 in September.

"Finally, inputs (defined as supplier deliveries, inventories, prices and imports) were mixed, with the Supplier Deliveries Index decreasing 0.3 percentage point, the Inventories Index declining another 2 percentage points and returning to contraction, and the Prices Index increasing 6.8 percentage points, returning to its level at the start of the Iran War. The Imports Index lost 1.5 percentage points, to 51 percent versus 52.5 percent in August.

"Looking at the manufacturing economy, 2 percent of the sector's gross domestic product (GDP) contracted in September, compared to 22 percent in August, and 2 percent of manufacturing GDP was in strong contraction (defined as a composite PMI® of 45 percent or lower), the same as in August. The share of sector GDP with a PMI® at or below 45 percent is a good metric to gauge overall manufacturing weakness. Of the six largest manufacturing industries, five (Computer & Electronic Products, Food, Beverage & Tobacco Products, Transportation Equipment, Machinery; and Chemical Products) expanded in September."

The 12 manufacturing industries reporting growth in September — listed in order — are: Electrical Equipment, Appliances & Components; Nonmetallic Mineral Products; Primary Metals; Plastics & Rubber Products; Computer & Electronic Products; Fabricated Metal Products; Furniture & Related Products; Food, Beverage & Tobacco Products; Transportation Equipment; Machinery; Miscellaneous Manufacturing; and Chemical Products. The two industries reporting a contraction in September are: Printing & Related Support Activities; and Textile Mills.

WHAT RESPONDENTS ARE SAYING

- "Better performance was driven primarily by temporary market effects, including (1) geopolitical uncertainties, (2) customers bringing forward purchases, (3) delayed raw material price increases and (4) reduced competitor capacity. However, these factors do not signal sustained recovery: Structural challenges facing the chemical industry remain, including overcapacity, persistent pricing pressures and protectionist trade policies." [Chemical Products]

- "Supply chain performance has improved compared to prior years, with lead times largely normalized. Cost pressures persist in select raw materials, transportation and labor categories, requiring continued focus on supplier management and cost control. We remain cautiously optimistic about business conditions over the next several quarters." [Chemical Products]

- "The U.S. tariff schedule is providing challenges. Finding alternate sources of supply outside of China, local pushback on data centers in the U.S. and continuing material/component shortages are affecting business." [Computer & Electronic Products]

- "Manufacturing activity remains stable, with a continued focus on cost optimization, supplier negotiations and supply base consolidation. We are actively evaluating alternative sources in several categories to improve supply resilience and reduce costs. While material availability has generally improved compared to prior periods, qualification requirements and supplier capacity constraints continue to influence sourcing decisions for certain critical materials and components. Capital and operational spending remain focused on productivity, efficiency and transformation initiatives." [Computer & Electronic Products]

- "Orders have doubled yet again, and delivery times have also doubled, in the semiconductor, electronics and government sectors, with remaining sectors flat to down. Coupled with supply chain lead times and pricing pressures, the factory backlog has nearly doubled. Canada tariffs have impacted cross-border costs and left our supply chain team scrambling — those supply chains took years to develop and nurture — hurting the very lead times government buyers are concerned about." [Machinery]

- "Order levels remain strong and elevated; we have orders through year-end at above forecast levels. Our biggest challenge continues to be a severe shortage of workers, limiting our production output to meet demand. The second challenge is general availability of steel; the market is getting worse, and more production delays are expected as we gap out of needed material." [Fabricated Metal Products]

- "Raw metals continue to be challenging, especially with the uncertain nature of tariffs being on and off again. New tariffs against Canada have drastically increased costs for capital expenses as well as assemblies." [Electrical Equipment, Appliances & Components]

- "Fuel costs are still affecting transportation costs and the overall cost of goods. Beef costs remain high, with no relief in sight." [Food, Beverage & Tobacco Products]

- "Higher interest rates slow down the growth of new construction projects; we also have to face up to the higher cost of components from overseas due to tariffs and freight rates. Due to booming demand of AI and data centers, domestic steel capacity has been stretched and pushed. Higher steel costs each month increase our raw-material and finished-goods costs." [Machinery]

- "Every month, we are faced with new headwinds created by this administration. This month, it is the trade war with Canada, which every day is getting worse — causing prices to go up and uncertainty that creates massive disruption. Buying continues to get pushed out indefinitely as customers don't want to spend on capital expenditures until there is more certainty of costs and demand. The only thing that is predictable is the chaos that is created by these trade policies." [Transportation Equipment]
