Manufacturer: who makes the product, and who the law says does
Published by Manufacturer Quotes. Editorial policy. Updated .
Definition
A manufacturer is a business that turns materials or parts into new products, usually in its own plant. US industry statistics define manufacturing as the mechanical, physical, or chemical transformation of materials, substances, or components into new products[1]. The legal meaning is wider: under US product safety law, a manufacturer is any person who manufactures or imports a consumer product[2].
What makes a business a manufacturer
The test is transformation. A business that takes inputs and produces something new, by cutting, molding, mixing, sewing, assembling or cooking, is manufacturing. The North American Industry Classification System, which US statistical agencies use, says such businesses are often described as plants, factories, or mills[1].
Owning machines is not strictly required. The same classification notes that manufacturers may process materials themselves or contract with other establishments to process their materials for them[1]. So a company can be counted as a manufacturer while another plant does the physical work, which is one reason the word on a supplier's website tells you less than you would hope.
Three meanings you will meet when you import
| Context | Who counts as the manufacturer | What it means for you |
|---|---|---|
| Industry statistics | A business that transforms materials into new products, even if it contracts out the processing | A useful description, but it does not tell you who runs the line |
| US product safety law | any person who manufactures or imports a consumer product[2] | If you import consumer products, the duties the law gives manufacturers can fall on you |
| Importer security filing | the entity that last manufactures, assembles, produces, or grows the commodity[3], or the party supplying the finished goods | The filing names either the plant that last made or assembled the goods or the party supplying the finished goods from the export country |
The second row surprises most new brands. Under the Consumer Product Safety Act, bringing a consumer product into the country is enough to make you its manufacturer, so duties the Act places on manufacturers can be yours, even if you have never seen the factory floor.
Manufacturer, trading company or brand
In sourcing, a manufacturer runs the plant where your product is made or last assembled. A trading company sells products that other plants make, and may add value by consolidating orders or handling export paperwork. A brand designs and sells the product and has it made, through contract manufacturing or by buying a factory's own design, which is the ODM route in OEM vs ODM. In food and drink, the plant that makes and packs for brands is usually called a co-packer.
The same product can involve all three, and none of them is automatically better. What matters is that you know which one you are dealing with, because it decides who can change the process, who can fix a defect and where the margin sits.
Example: one product, three companies
| Company | What it does | Manufacturer in which sense |
|---|---|---|
| Factory in Ningbo | Presses, welds and polishes the bottles and packs them | All three: it transforms the steel, makes the product and last assembles it |
| Trading company in Shenzhen | Takes the order, sets the price and books the export | Not the maker. In the filing's manufacturer (or supplier) field it can appear only as the supplier of the finished goods, the alternative the rule allows |
| Your brand in the US | Designs the bottle, approves the sample and imports it | Manufacturer under product safety law, because it imports |
Illustrative figures, not a quote. Real prices depend on the spec, quantity and factory.
In this example the factory is the entity that last manufactured the bottles in the filing's sense, and your brand still carries the product safety duties. When you are finding a manufacturer, ask early which of these roles each supplier plays.
