Marking of Country of Origin on U.S. Imports
Every article of foreign origin entering the United States must be legibly marked with the English name of the country of origin unless an exception from marking is provided for in the law.
What articles are excepted from marking by 19 U.S.C. 1304?
The following exemption applies to 3D resins as supplied:
- The article is to be processed in the United States by the importer, or for his account, in such a manner that any marking would be permanently concealed, obliterated, or destroyed
since 3D resins are photoreactive liquids, which react undergoing a photochemical synthetic reaction in the printers, which are phtochemical reactors, which selectively "cure" the resins in certain zones, layer by layer or continuously, to shape "solid" 3D prints, which after postcuring and postprocessing, are placed on the market as printed objects, consequently any marking would be permanently concealed, obliterated, or destroyed once placed on the US market after being processed by the importer or by the relevant account . The same principles apply to the manufacturers of medical devices, who are responsible for getting their own certifications,
