CertSeven

The texts we quote, and how we check them

Everything this site states about the rules is a dated quotation. Here is the whole list, and the method.

20 sources, 144 recorded quotations · last checked on 11 October 2026

The method, in four points

Nothing is written from memory. Every sentence on this site that says something about the rules points to a quotation recorded in a sources file, with its URL and its date. A script re-downloads each source and refuses to record anything if a single quotation is no longer found in it, word for word.

What you read between quotation marks is that recorded text, shown as it stands. When the source is not in your language we show our translation and say so underneath. A paraphrase never passes for a quotation.

Dates matter more than people expect. CPSC, customs and postal pages change without notice, and a page that does not say when it was checked says nothing at all. Every quotation carries its own.

What we do not do: decide for you, write that a certificate is "compliant", or file anything with American customs. We set out the texts and prepare your documents; responsibility for the certificate stays with the certifier.

The sources, one by one

Each is published by the body or company that signs it. The links go to the original page or PDF, not to a copy.

And American law itself

The text of the title 16 rules comes from the eCFR API, never retyped by hand. The issue in use on this site is dated 2026-10-01, and each part's amendment date is kept with it - which is what lets a certificate be flagged when a rule it cites has moved since it was issued.
