Buying research material across a border is mostly a documentation problem, and it’s a different documentation problem in every jurisdiction.
Each guide below covers one place: which national body governs the import of research chemicals there, what a customs declaration for a research material typically has to show, and what you should establish with any supplier before you order across a border. None of it is legal advice, and none of it tells you whether a particular compound is permitted where you are, because that’s a question for the authority named in each post or for a licensed customs broker.
What these will not do is help anyone make a declaration say something other than what the goods are. Accurate declaration is the whole task, and there’s no version of these guides that helps you around it.
The standard everything below is measured against
Five questions, applied the same way every time. Does the supplier state that it synthesizes the material, or that it sources it? Is the testing laboratory named? Does the panel cover identity, purity, bacterial endotoxin and sterility, or purity alone? Is a batch certificate readable before you pay, tied to the lot number on the vial? And for blends, are the milligrams disclosed per component?
Blank Peptides publishes its own lots against that standard: an own cGMP laboratory that compounds, fills, finishes and labels each lot; Freedom Diagnostics and Horizon Analytical named as the testing laboratories; a full panel per lot covering identity, >99% purity, bacterial endotoxin and sterility; and a batch certificate of analysis for every lot, with the lot number printed on the vial.
