Anonymous manufacturers
<p>Some manufacturers are not putting their names on their products: no contact numbers nor e-mail address for support to keep in touch with the manufacturer if something happens to your bought item(s).</p>
<p>Is there any legal requirement for the manufacturer to make themself known?</p>

<p>Sort of. In the US, an example of a labeling requirement is <a href="https://www.ecfr.gov/current/title-16/chapter-II/subchapter-B/part-1101" rel="nofollow noreferrer">16 CFR Part 1101</a>. In certain circumstances, there must be &quot;public disclosure of information from which the identity of a manufacturer or private labeler of a product can be readily ascertained&quot;. Not everything is subject to this mandatory disclosure – it is driven by safety of consumer products. The Consumer Product Safety Commission summarizes some of the requirements <a href="https://www.cpsc.gov/Business--Manufacturing/Business-Education/Business-Guidance/CPSC-Labeling-Requirements-Overview" rel="nofollow noreferrer">here</a>, and the strongest requirements are on &quot;child products&quot;. A train car-load of pig iron would not be subject to such labeling (but then, you would probably know the manufacturer from the contract that you had to buy the iron). You can garner all of the safety regulations from <a href="https://www.ecfr.gov/current/title-16/chapter-II" rel="nofollow noreferrer">16 CFR Ch. II</a>. <a href="https://www.ecfr.gov/current/title-16/chapter-I" rel="nofollow noreferrer">16 CFR Ch. I</a> is the regulations established by the FTC under the Fair Packaging and Labeling Act. This requires all &quot;consumer products&quot; to have a label, especially <a href="https://www.ecfr.gov/current/title-16/chapter-I/subchapter-E/part-500" rel="nofollow noreferrer">Part 500</a>. This only applies to commodities in a package or with a label (not hardware from a bin or bulk sim-cards). §500.5 is the section that says that you have to say who the manufacturer is.</p>
