FOB Value in Peptide Shipments to Argentina

FOB (Free On Board) is the price of the goods at the point of loading in the country of origin, before international freight or insurance is added. On a research peptide shipment, it's the number written on the commercial invoice, and Argentina's customs authority, the Dirección General de Aduanas (DGA), checks that figure against its own reference values before releasing the package.

What "FOB" means on an invoice

FOB describes a sale condition, not a category of goods. When a supplier quotes "FOB origin," the declared price covers the product loaded onto the outbound carrier — nothing past that point. International freight, insurance, and any handling that happens afterward are added separately, and that split is exactly what customs authorities worldwide use to calculate the taxable value of an import.

In practice, the commercial invoice that travels with a shipment of lyophilised research peptides usually carries three figures: the FOB value of the product, the freight (when it's declared separately), and the resulting CIF value — Cost, Insurance and Freight — which is the base Argentine customs uses to calculate duties when a shipment enters through the formal channel.

Why Argentine customs checks that number

The check exists because the declared value is the taxable base for import duties and, where applicable, VAT. An underdeclared FOB value artificially shrinks those taxes, so AFIP doesn't treat the importer's invoice as the final word — it compares it against its own data.

The main tool is the valor criterio, a reference floor that customs builds from statistics on previous imports of the same tariff heading, the same origin, and comparable goods. If the declared FOB value falls below the valor criterio in force for that heading, Argentina's customs system — Malvina, the successor to the old SIM — automatically routes the shipment into a stricter verification channel, and the customs broker has to justify the gap with supporting documentation or accept that duties get calculated on the reference value instead.

That check runs alongside the ordinary documentary review: whether the invoice, the packing list, and the declaration agree on quantity, weight, and description of the goods. A peptide declared as "laboratory reagent, research use" at a stated weight of 10 mg with a two-dollar FOB value draws attention if the valor criterio for that heading sits well above it.

How a research peptide shipment actually enters the country

Most research peptide shipments into Argentina arrive by international courier, not through a formal customs clearance handled by a broker. The courier/postal regime runs its own simplified circuit: the courier company files a declaration (the former SIM, now folded into the Malvina system) with the value, weight, and description of each parcel, and AFIP processes it against the same reference-value logic, though with different thresholds and exemptions than a commercial import.

That simplified path doesn't mean the check is lighter — it means it runs faster and with less manual intervention, unless something trips an alert: a value out of range, an ambiguous description, or a recipient whose past shipments were already flagged.

The description of the goods on the invoice matters as much as the number itself. PeptoClinic ships research peptides to Argentina with the paperwork built for exactly this circuit: a commercial invoice describing the material as laboratory reference material, the tariff heading that applies to chemical reagents, and the batch's certificate of analysis attached.

What happens when the declared value doesn't match the reference

When the system flags a meaningful gap between the declared FOB value and the valor criterio, the shipment moves into a verification channel. There, customs can request supporting documentation — the purchase order, proof of payment, the certificate of analysis identifying the batch — to reconstruct the actual value of the transaction.

If the gap isn't justified, customs has the authority to recalculate duties on the reference value instead of the declared one, on top of the delay a manual review already adds. That's why, for any international shipment, declaring the real transaction value — neither inflated nor underdeclared — is what keeps a package from sitting in bonded storage while the gap gets resolved.

That's also exactly why a certificate of analysis with a date, a lot number, and a verifiable laboratory matters beyond quality control: it's the document that backs the declared value and description if customs asks for justification. Janoshik Analytical analysed the retatrutide and MOTS-c batches PeptoClinic publishes, at 99.893% and 99.669% purity respectively — the lower of the two published figures. Reports like that are the kind of documentary backing that sits behind a coherent value declaration.

Retatrutide, BPC-157, and the "laboratory reagent" tariff heading

Synthetic lyophilised research peptides don't have their own dedicated tariff heading — they're classified under the headings for reagents and organic compounds used in laboratory work, and that classification is what fixes which valor criterio applies. An imprecise description on the invoice ("peptide," with nothing further) complicates that classification and is one of the most common causes of delay once a shipment lands in the verification channel.

The retatrutide page for Argentina and the BPC-157 page for Argentina spell out the documentation that travels with each batch — the same paperwork that supports the declared description and value if it's ever questioned. The same goes for GHK-Cu: every lot ships with its own certificate of analysis, verifiable independently of the invoice.

What this is not: research material, not a consumer product

Everything imported under this category is strictly for laboratory research use (RUO — Research Use Only). It is not a medicine, not a supplement, and not approved for human or veterinary consumption, diagnosis, or treatment. No claim about these compounds has been evaluated by ANMAT, the FDA, or any equivalent authority. The value and tariff-classification documentation described here applies to that use — laboratory reference material — and to no other.
