Industry Summary
The 5,800 industrial supply distributors in the US purchase maintenance, repair, operating, and production (MROP) supplies in bulk and resell them to customers in smaller quantities. Product categories include abrasives, strapping, tape, and inks; mechanical power transmission supplies; industrial containers and supplies; industrial valves and fittings; and welding supplies. Distributors may offer technical support, repair, or assembly services.
Offshore Production
Offshoring of manufacturing production to low-wage countries reduced demand for domestic industrial supply distributors.
Growth in Green
The growing interest in the environment and energy efficiency has created a demand for “green” products and expertise.
Recent Developments
Jun 8, 2026 - Brisk Uptick in Manufacturing Activity
- US manufacturing activity expanded in May at the fastest pace in four years, bolstered by a pickup in new orders and production, Bloomberg reports. Nearly every manufacturing industry reported growth last month, including printing, textiles, electrical equipment and plastics. The rise in the Institute for Supply Management’s manufacturing gauge signals improving demand from manufacturers and increased opportunities to supply them with materials, equipment, and MRO products. However, rising input costs, higher energy prices, and supply chain disruptions are putting upward pressure on prices. Some manufacturers are also accelerating purchases and building inventories ahead of potential cost increases, which could temporarily boost distributor sales. While factory activity is expanding and order backlogs are growing, distributors need to monitor inflation and supply constraints that could affect product availability and margins. Overall, the ISM data suggest a favorable demand environment for industrial supply distributors, though cost management and inventory planning remain critical.
- US manufacturing activity expanded for the third consecutive month in March, according to the latest ISM Manufacturing Purchasing Managers’ Index report. March’s PMI of 52.7% signals ongoing growth, with production and new orders remaining in expansion, supporting steady demand for industrial supplies. However, distributors face mounting pressure from a sharp increase in the Prices Index (up 78.3%), indicating rapid cost inflation across inputs and threatening margins. (In the last two months, the Prices Index has increased 19.3% to its highest level since June 2022.) At the same time, slower supplier deliveries point to ongoing supply chain delays, complicating inventory management and order fulfillment. Customer inventories remain low, which may support near-term demand, but export orders have weakened and employment remains in contraction, signaling potential softness ahead. Geopolitical tensions, including the Iran war, and ongoing tariff uncertainty are adding volatility and causing cautious business sentiment.
- The Trump administration’s on-again, off-again tariff strategy is sending ripples through the industrial sector, significantly impacting production costs, supply chains, and overall competitiveness in the machinery and industrial equipment sector, Manufacturing.Net reports. The implementation of an additional 10% tariff on Chinese imports, suspension of de minimis exemptions for Chinese shipments, and newly announced (and since delayed) 25% tariffs on goods from Mexico and Canada, are causing confusion and requiring manufacturers to quickly adapt to mitigate potential cost spikes and avoid supply disruptions. Manufacturers looking to reshore operations to avoid tariffs and shorten their supply chains are an opportunity for domestic industrial supply distributors. However, rising recessionary fears could cause existing and potential customers to delay or cancel new orders. In March, Goldman Sachs raised the probability of a US recession to 35% from 20%, amid tariff turmoil and economic uncertainty.
- Producer prices for machinery and industrial supply wholesalers, a key indicator of labor and operating costs, rose 14% in April from a year earlier, following a 6.4% year-over-year increase in the prior April, according to the latest data from the US Bureau of Labor Statistics. The sharp rise reflects higher equipment acquisition costs that distributors are increasingly passing along to customers. Meanwhile, employment among industrial supplies merchant wholesalers grew 1.5% year over year in March. Average hourly wages in the industry climbed 11.7% over the same period to $33.28, though that figure remained $0.56 below the peak reached in September 2025, according to BLS data.
