Equipment is any item that retains its shape with use, serves its purpose for at least one year, and is worth repairing rather than replacing when it breaks. That core definition holds across accounting, tax law, healthcare, and industry, though each field adds its own specific thresholds for cost, durability, and intended use. Whether you’re classifying purchases for a business, filing taxes, or figuring out what Medicare covers, the same basic question applies: is this item built to last and be reused, or is it consumed and discarded?
The Four Criteria That Define Equipment
The National Center for Education Statistics outlines four criteria that are widely used across organizations to distinguish equipment from supplies. An item qualifies as equipment when it meets all four:
- Retains its form. It keeps its original shape, appearance, and character through use.
- Keeps its identity. It doesn’t get absorbed into another product or substance. A drill is equipment; the drill bit that wears down and gets tossed is a supply.
- Is worth repairing. If it breaks or loses parts, repairing it makes more sense than buying a new one. This is what “nonexpendable” means in plain terms.
- Lasts at least one year. Under normal use and reasonable maintenance, it can serve its main purpose for a minimum of 12 months.
If an item fails any one of these tests, it’s typically classified as a supply. A ream of paper, a box of gloves, a ink cartridge: none of these retain their form through use or last indefinitely, so they’re supplies. A printer, a centrifuge, a forklift: all hold their shape, keep their identity, justify repair costs, and last well beyond a year.
How Cost Affects the Classification
Durability alone doesn’t settle the question. Cost plays a major role, especially for tax and accounting purposes. The IRS allows businesses to expense (deduct immediately) items below a certain dollar threshold instead of capitalizing them as equipment and depreciating the cost over several years.
Under the IRS de minimis safe harbor rule, businesses without audited financial statements can expense items costing $2,500 or less per invoice. Businesses with applicable financial statements (typically audited or reviewed by an independent CPA) can expense items up to $5,000 per invoice. Anything above those thresholds that meets the durability criteria is generally capitalized as equipment on the balance sheet.
This is why classification can shift over time. The NCES notes that handheld calculators were once classified as equipment when they cost over $100. Now that most cost between $5 and $25, many organizations reclassify them as supplies. The physical item didn’t change, but its economic significance did.
Equipment in Healthcare: The DME Standard
Healthcare uses a more specific definition. Medicare defines Durable Medical Equipment (DME) as any item that meets five requirements: it can withstand repeated use, it serves a medical purpose, it’s generally only useful to someone who is sick or injured, it’s appropriate for use in the patient’s home, and it has an expected life of at least three years. That three-year threshold is notably longer than the one-year standard used in general accounting.
Common examples include wheelchairs, hospital beds, oxygen concentrators, and CPAP machines. A box of bandages or a pack of syringes wouldn’t qualify because they’re single-use. A blood pressure cuff sits in a gray area: it’s reusable and medically necessary, but whether Medicare covers it depends on whether a doctor prescribes it for home use and whether the specific model meets the durability standard.
Items classified as DME after January 1, 2012, must also be FDA-approved for their intended purpose and considered reasonable and necessary for the individual patient. Coverage decisions for items that don’t fit neatly into existing categories are made on a case-by-case basis by regional Medicare contractors.
Heavy vs. Light Equipment
In industrial and commercial settings, equipment gets further divided by scale. The dividing line between light and heavy equipment is typically 10,000 pounds of Gross Vehicle Weight Rating (GVWR). Pickup trucks, small compressors, and portable generators fall below that threshold. Bulldozers, semi-trucks, cranes, and industrial excavators sit above it.
This distinction matters for licensing, insurance, maintenance scheduling, and the technicians who service the machines. Light-duty equipment generally uses smaller diesel or gasoline engines found in passenger vehicles. Heavy-duty equipment requires specialized powertrains designed for sustained high-output work, and the maintenance costs, replacement cycles, and regulatory requirements are substantially different.
The Equipment Lifecycle
Once something is classified as equipment, organizations track it through four phases: planning, procurement, operation and maintenance, and disposal. The operation and maintenance phase is the longest by design. It covers the entire useful life of the item, from its first day of service through routine upkeep, repairs, and performance checks.
Planning involves identifying the need and budgeting for the purchase. Procurement is the actual acquisition, whether bought outright, leased, or financed. During the operation phase, the goal is to keep the equipment performing at its intended level for as long as economically practical. Disposal happens when repair costs exceed the item’s value, when it becomes obsolete, or when regulations require decommissioning. Proper disposal can involve resale, recycling, trade-in, or certified destruction depending on the type of equipment and any environmental or data-security requirements.
Equipment vs. Assets: A Key Distinction
Equipment is always an asset, but not every asset is equipment. Under the ISO 55000 international standard, an asset is anything that has potential or actual value to an organization. That includes equipment, but also buildings, land, software licenses, patents, and even data. Equipment specifically refers to the physical instruments, machines, and devices that perform a function.
In laboratory settings, for example, centrifuges, fume hoods, and calibrated pipettes are all equipment. They undergo formal performance qualification to verify they produce accurate results, followed by routine calibration checks and preventive maintenance throughout their service life. The reagents and test kits consumed during experiments are not equipment. They’re consumables, classified and budgeted separately.
Practical Rules for Classifying an Item
If you’re trying to decide whether something counts as equipment, run through these questions in order:
- Does it keep its shape after use? If it gets used up, broken down, or incorporated into something else, it’s a supply or raw material.
- Will it last at least a year? Items with a shorter useful life are consumables, regardless of cost.
- Is it worth repairing? If replacing it is cheaper or easier than fixing it, most organizations treat it as expendable.
- Does it exceed your cost threshold? For tax purposes, items under $2,500 (or $5,000 with audited financials) can be expensed immediately rather than tracked as equipment. Many organizations set their own internal capitalization thresholds within these IRS limits.
An item that passes all four checks is equipment. The level of tracking and control an organization applies to that equipment, from asset tags to maintenance schedules to depreciation records, typically scales with how much the item cost and how critical it is to operations.
