# How to order an analysis (COA)

> Seller guide to ordering the laboratory analysis of a sample at EXTRACTOS EUM®: register the sample, choose the type of analysis, print the shipping sheet with QR, pay, and follow the progress up to your Smart COA.

> For a product to have its [Smart COA](smart-coa.md), you need to analyze the **batch**. Here you order that
> analysis: you register the sample, send it to the laboratory with its shipping sheet, and follow the progress until
> the COA is ready and verifiable.

## 1. Register your sample

You capture the sample's data:

* **Description** and **commercial reference** (what it is).
* **Declared weight/volume** + unit (g, kg, ml, l, or pieces).
* **Batch** reference.
* **Result type:** **total potency** (report %) — typical of raw material/distillate — or **profile**
  (cannabinoid profile of the finished product, with the net weight of the presentation).

## 2. Choose the type of analysis

Depending on what you need: **cannabinoids** (potency/profile, the most common), **microbiological**, **heavy
metals**, and other safety panels. You can add several analyses to the same sample.

## 3. Print the shipping sheet

The system generates a **sample shipping sheet** with a **QR** that links it to your order. It goes with the sample to the
laboratory so they identify it without errors.

## 4. Pay

The charge for the analysis is generated (checkout). Once the payment is confirmed, the sample is ready to be shipped.

## 5. Ship and follow the progress

You send the sample and follow its status in [My orders](consumidores/mis-ordenes.md):
**registered → on its way → received → in analysis → COA available**. When the laboratory uploads results
and EUM **releases** them, your [Smart COA](smart-coa.md) becomes public and verifiable (QR/CVV), with **validity
of 657 days from the analysis date**.

## After the COA

* Link it to your product/variant and generate the **label** ([Label anatomy](cumplimiento/etiquetado.md)).
* If it's a **raw material**, its COA can be **linked** to the COA of the finished product that uses it
  ([ingredient traceability](smart-coa.md#8-trazabilidad-del-ingrediente-coa-del-producto--coas-de-sus-materias-primas)).

*Verified against the production system (2026-08-01).*
