I have kept every message, invoice and document, which I gather is the useful habit.
I can parse the result. I am less sure what it licenses me to conclude.
I have deliberately not looked at anyone else’s interpretation yet.
Which parts of this are informative and which are decoration?
The short version: research-use designation is a labelling convention, not a legal exemption, and it does not travel across borders.
Three broad categories cover most cases: controlled or scheduled substances, prescription-only medicines, and unclassified chemicals. The rules, penalties and enforcement posture differ sharply between them.
On the detail: enforcement posture and legal position are not the same thing. Consignments arriving without incident establish nothing about the underlying rule.
Medicines regulation and drug-control law are distinct legal frameworks in most countries, with different scheduling and different penalties.
If the stakes are material, ask a lawyer where you live rather than a forum anywhere.

A research-use-only label is a supplier's statement about intended use. It has no status in customs classification and does not create an exemption for the importer.
Onward supply — including at cost, including to friends — is treated separately and much more seriously in most regimes than importation for personal use.
Research-use labelling is a seller's statement, not a legal category for you.
The honest answer is that personal importation of a prescription-only medicine is restricted in most jurisdictions regardless of intended use.
Most agents discussed on this site are prescription-only medicines where they are licensed at all, which places personal importation under medicines regulation rather than under drug-control law in most jurisdictions.
If the amount at stake is material, this is a question for a lawyer in your jurisdiction rather than for a forum in any jurisdiction.
Research-use-only labelling is a commercial convention originating in laboratory supply and carries no regulatory status for an individual importer.
Personal importation and onward supply are different acts under different rules.

Selling on is a different legal act from importing for yourself, in essentially every jurisdiction.
Some jurisdictions provide a limited personal-importation allowance for medicines, usually bounded by quantity, by a supply period and by a requirement that the substance is for the importer's own use. Others provide none.
Absence of enforcement is not permission, and prior deliveries prove nothing about the rule.
Prior successful deliveries tell you about enforcement, not about legality.
Concretely, the relevant distinction is between substances that are scheduled, substances that are prescription-only medicines and substances that are unclassified.
The authority that matters is the national medicines regulator plus the customs authority, and both usually publish their position in plain language on their own websites.
Onward supply is a materially different legal act and should not be assumed to follow the same rule as personal importation.
Look up your own regulator and customs authority. They publish the answer directly.
