# §23.16. What are the U.S. CITES requirements for urine, feces, and synthetically derived DNA?

- (a) **CITES documents.** We do not require CITES documents to trade in urine, feces, or synthetically derived DNA.
  - (1) You must obtain any collection permit and CITES document required by the foreign country.
  - (2) If the foreign country requires you to have a U.S. CITES document for these kinds of samples, you must apply for a CITES document and meet the requirements of this part.
- (b) **Urine and feces.** Except as provided in [paragraph (a)](#a) of this section, we consider urine and feces to be wildlife byproducts, rather than parts, products, or derivatives, and exempt them from the requirements of CITES and this part.
- (c) **DNA.** We differentiate between DNA directly extracted from blood and tissue and DNA synthetically derived as follows:
  - (1) **A DNA sample directly derived from wildlife or plant tissue is regulated by CITES and this part.**
  - (2) A DNA sample synthetically derived that does not contain any part of the original template is exempt from the requirements of CITES and this part.
