How to find a company's manufacturer from labels and public records

What you can and cannot find

The company on the box is often not the company that made what is inside it. Private label and contract manufacturing are common, so the brand owner often designs and sells while a separate factory produces. Public sources can usually tell you who is legally responsible for a product in the US and which country it came from. They name the actual factory less often, and when they do, the name needs checking.

Work through the sources below in order. The first ones cost nothing and take minutes; the last ones take longer and give leads rather than answers.

How to find a company's manufacturer

1. Read the label for the responsible company. A packaged food label must state the name and place of business of the manufacturer, packer, or distributor^[1]. If the company named did not make the product, the name has to carry a phrase such as "Manufactured for" or "Distributed by"^[1]. Over-the-counter drug labels must also bear the name and place of business of the manufacturer, packer, or distributor^[2], and a distributor's name is qualified with a phrase such as "Manufactured for", "Distributed by" or "Marketed by"^[2]. So "Manufactured by" points at the maker, "Manufactured for" and "Distributed by" tell you the named company is not it, and a label reading "Manufactured by one company for another" names both.
2. Look up the RN on clothing and textiles. A textile label shows either the company name or the Registered Identification Number (RN) of the manufacturer, importer or another firm marketing, distributing or handling the product^[3]. The FTC keeps a public database that shows which company holds each RN. RNs are not issued to businesses outside the U.S.^[3], so an RN leads you to a US company (a manufacturer, importer, brand or wholesaler), never to an overseas factory. That company is still useful: it is the one whose import records you look for next.
3. Check the tracking marks on children's products. Makers of children's products must mark the product and its packaging, where practicable, so the buyer can find the manufacturer or private labeler, location and date of production^[4]. The mark may name a private labeler rather than the factory, but the location and date narrow the search.
4. Note the country of origin. Unless an exception applies, imported goods or their containers must be marked with the English name of the country of origin^[5]. That tells you where to look, not whom to call.
5. Check the company's own website for a supplier list. If the company publishes the factories it uses, that list is the most direct answer you will get. Record the date on it, because supplier lists change.
6. Search US ocean import records. Members of the public may not examine vessel manifests, but may request and obtain information from them from CBP^[6]. CBP's automated manifest data is compiled daily and available to the public at the government's production cost, without the data of parties that requested confidentiality^[6], and its data elements include the shipper name and address, the consignee name and address, the foreign port of lading and a description of the goods^[6]. Commercial customs data services compile these records into searchable databases. They draw on the same manifest data, so the same gaps apply, and if you use one, read its terms before you rely on or reuse what it shows.
7. Confirm the lead before you act on it. A name on a record is where you start. Check that the company exists, that it manufactures rather than trades, and that it makes the category you care about. A factory audit is the thorough version of that check.

Why import records often come up empty

Two things limit what customs data shows. First, an importer can ask CBP to keep confidential its own name and address and the names and addresses of its shippers^[6]. CBP grants these requests for two years, with no fee^[7], so a company with no visible shipments may simply have filed one. Second, advance cargo information for goods arriving by air, rail or truck is exempt from disclosure^[8], so goods that fly in, or cross from Mexico or Canada by truck or rail, generally do not appear in public manifest data at all.

When a record does name a shipper, it names whoever shipped the goods. That can be the factory, but it can also be a trading company or a freight forwarder acting for it. Write down exactly what the record says, for example "customs records list this company as shipper on these shipments to this consignee, on these dates", rather than a conclusion the record does not state. It keeps your notes honest and your supplier list accurate.

When you are looking for a supplier, not an answer

Many people search for a product's maker because they want to make something in the same category under their own brand. For that, the one factory behind someone else's product matters less than finding factories that can make your design, at your quantities, with the certifications your market needs. That factory's minimum order, capacity and current order book may not fit you anyway.

Start from your own spec and your MOQ, and judge any factory on price, lead time and landed cost, not on whose products it has made. When you request quotes from us, we source them from manufacturers in your category and sell to you at one price per unit that includes our margin; each quote states its shipping terms.
