Peptide Shipments to Argentina: Annual Limit

Argentina's postal shipment regime no longer caps the number of packages a person can receive in a year — the old limit of five tax-exempt shipments per calendar year was eliminated in the late-2024 reform. What the regime still controls is the declared value of each individual shipment, which decides whether it owes duties and how much. This applies to any package entering through the simplified postal or courier ("door to door") regime, including ones carrying research material such as peptides.

What changed in 2024: from a quantity cap to a value threshold

Before the reform, the system worked as a quota: an individual was entitled to a fixed number of duty-exempt purchases per calendar year, and once that count was reached, the next shipment paid a high flat rate regardless of its actual value. That created a specific problem for anyone ordering more than one package a year — a sixth shipment, for instance, paid the same as a high-value import, even if it cost a few dollars.

The reform replaced that quota with value tiers. In practice, this means the number of shipments you receive in a year no longer has a ceiling: you can receive ten, twenty or fifty packages, and each one is assessed on its own declared value, not on the order in which it arrived. The test shifted from "how many did you order" to "what is each one worth."

How the postal shipment regime works today

The current scheme works with FOB value brackets declared per shipment:

• Low-value shipments are exempt from import duties and VAT.
• Mid-value shipments pay a reduced rate compared with the general import regime.
• Higher-value shipments, up to the ceiling the simplified regime allows (above which a formal import procedure applies), pay under the general import regime.

The exact amounts for each bracket are set by AFIP and adjusted periodically, so before estimating what a shipment will owe, check the current figures at afip.gob.ar, the official source and the only one that matters if it conflicts with anything on this page or any other.

What does not change as the bracket amounts get updated is the underlying logic: the postal shipment regime was built for low-volume personal purchases, not commercial importation. A shipment declared correctly — with its real value and a description that matches what's actually inside — is what keeps a package inside this simplified regime instead of pushing it into a formal import procedure.

What this means for someone receiving research peptides

For someone receiving research material such as retatrutide, BPC-157 or MOTS-c through this channel, removing the quantity cap solves the most common friction point: ordering a second or third shipment in the same year without that automatically triggering a different tax treatment. What still matters is:

• That the declared value of the shipment is the real one.
• That the description of the contents matches what's actually traveling — in this case, laboratory reference material, not a consumer product.
• That the recipient is an identified individual, with the information the simplified regime requires, including a CUIT or CUIL.

PeptoClinic prepares the customs file for every order bound for Argentina describing the contents as what they are: laboratory research reference material. That description is the correct one to declare, and it is independent of how many prior shipments the same person has received that year — again, because the regime no longer counts shipments, it counts value.

The documentation that travels with each shipment

A shipment of research peptides doesn't arrive with just a customs label. What accompanies the vial, at minimum, is the laboratory report certifying what's inside. PeptoClinic works with reports from Janoshik Analytical: the analyzed MOTS-c lot came back at 99.669% purity and the retatrutide lot at 99.893%, each with a verifiable task number. How to read those reports — what each field means, what to ask if a number doesn't add up — is explained on the quality page.

What the package does not carry is a cold chain: the material ships as lyophilized powder in a sealed vial with desiccant, stable at room temperature for weeks, with no coolant and no insulated packaging. Cold only starts to matter after reconstitution, not during transit. The full detail of how material is packaged and why is on the shipping page.

Research material, not for human use

Everything described here is information about a customs procedure, not a usage guide. The material PeptoClinic supplies is intended exclusively for laboratory research — in vitro and reference use — and is not approved for human or veterinary consumption, is not a drug or a supplement, and no regulatory body has evaluated these statements. No prescription is written, filled or required, and any question about human-use protocols falls outside what this business answers.

What to check before ordering a shipment

Three things, in order of importance:

• The current bracket amounts. These are updated by AFIP resolution and aren't fixed indefinitely, so a figure that was correct a year ago may not be today.
• Whether the courier or postal carrier handling the shipment has its own additional policies. The national regime sets the floor, but some logistics companies add their own operational limits on package volume in transit.
• That the description and declared value of the contents are accurate. This is the one thing fully within the control of whoever requests the shipment, and it's what decides which bracket it falls into.

Outside those three points, there is no additional procedure tied to how many orders you placed earlier that same year — that count, under this regime, no longer exists.
