Is it legal to import peptides into the US?

This site does not hold a US import classification. Legal-status fields record national approval or research-use status. They do not record customs rules, personal-importation allowances, or whether a parcel labeled research use only may cross a border. Import is a different legal question from the US field on /legal. This FAQ will not fill that gap with a guess, and it does not invent a state or port rule. Check the compound's US legal page for the national status this site actually stores.
