Wholesalers by Category

Wholesale supply does not work the same way across industries. Minimum orders, account requirements, freight arrangements and the gap between a manufacturer, an authorized distributor and an open-market seller all shift by category.

Each page below covers one industry: the kinds of suppliers operating in it, who they sell to, what they publish about their requirements, and what a buyer should check before placing a first order.

What changes between industries

How the goods are identified. A handset is defined by lock status, regional variant and grade. An equipment part is defined by machine serial number. A tile is defined by batch. Getting the identifier wrong produces a delivery that is technically correct and commercially useless, and the identifier differs in every category.

What the minimum is set by. Some categories price by case pack, some by pallet, some by area, some by truckload. The minimum that blocks your order is rarely the dollar figure on the account form.

Where the freight cost sits. In heavy categories freight can exceed the margin on the goods. In light, bulky ones the freight classification matters more than the weight. In high-value ones the number of handling touches matters more than either.

What compliance attaches. Code approval for mechanical and electrical work, certification for anything carrying power, handling rules for chemicals. These are enforced by someone other than the supplier, and after the sale.

What U.S. wholesalers sell, by official classification

The U.S. industry classification used by the Census Bureau, NAICS, treats wholesale trade as sector 42. Its 2022 manual describes wholesalers as businesses that sell goods to other businesses, generally without transforming them: goods for resale, capital or durable goods used by businesses, and raw materials and supplies used in production. They normally operate from a warehouse or office with little or no display, and do not normally advertise to the general public.

The sector splits into three subsectors:

• 423, durable goods merchant wholesalers: items with a normal life expectancy of three years or more, such as construction materials, machinery and equipment, appliances, electronics, sporting goods and parts.
• 424, nondurable goods merchant wholesalers: items with a normal life expectancy of less than three years, such as paper products, drugs, apparel, groceries, chemicals and farm products.
• 425, wholesale trade agents and brokers: businesses that arrange sales of goods owned by others, generally for a fee or commission, rather than selling stock of their own.

The classification tells you what kind of goods a business handles, not how well it serves a new account. Use it to describe your category accurately when you search or speak to a supplier.

Types of wholesalers you will meet

NAICS recognizes two main types. Merchant wholesalers sell goods on their own account; the manual lists wholesale merchants, distributors, jobbers, drop shippers, import/export merchants, manufacturers’ sales offices and branches, and group purchasing organizations that buy and sell for themselves. Agents and brokers arrange purchases or sales for others; the list includes business-to-business electronic markets, commission merchants, import/export agents and brokers, auction companies and manufacturers’ representatives.

Lists that count “nine types” or another fixed number are informal groupings of these names, not an official scheme. What matters for a first order is whether the business owns and ships the goods, or arranges the sale while someone else holds the stock. The supplier-role guide explains how to confirm that.

How the category guides on this site compare

Each guide below sits mainly in one part of the classification, but a guide can span more than one code. Decorative surfaces, for example, include stone and structural clay products in durable construction materials, while wallpaper is classified with paint supplies under nondurable goods.

Apparel sourcing and remaining category gaps

For apparel-specific sourcing roles, regional research and order checks, use the U.S. wholesale clothing channel guide alongside the U.S. wholesale clothing vendors and apparel hubs guide covering Los Angeles, New York City, Dallas, and Atlanta hubs, ASTM Missy versus Junior prepack sizing, and FTC/CPSC/Prop 65 compliance. In NAICS, apparel falls under 4243, apparel, piece goods and notions merchant wholesalers. This section does not currently include a guide for health and beauty products. Cosmetics and vitamins appear among the examples for 424210, drugs and druggists’ sundries merchant wholesalers. For those categories, use the cross-category checks below and ask each supplier how it identifies the goods, sets its minimum and documents any regulatory requirements for the product.

What stays the same

The company checks, the account paperwork and the quote comparison do not change by industry. Those are covered in the supplier research and buying sections, and they apply before any of the category-specific questions below become relevant.
