The Toxic Substances Control Act (TSCA) is a United States law, administered by the Environmental Protection Agency (EPA), that regulates the introduction of new or already existing chemicals.

Sometimes Your package with a typewriter can be held in customs and You will be asked to send this declaration to release it from customs. However, it doesn't generally pertain to items like manual typewriters and normal ink ribbons.

In the case of a manual typewriter and normal ink ribbon, these are finished products, and they aren't generally considered to be chemical substances in and of themselves.

The ink in the ribbon may contain various chemical substances, but by the time it's incorporated into the ink ribbon and packed with the typewriter, it's not typically subject to TSCA regulations.

Therefore, if these are the only items in your shipment, you could most likely provide a Negative Certification, stating that all chemicals in the shipment are not subject to TSCA. This is because TSCA is primarily concerned with chemical substances on their own or within mixtures, rather than finished products like typewriters and ink ribbons.

Please note that the regulatory environment can change, and there may be additional factors to consider that aren't covered in this general advice and our experience.
