Which CGM Sensors Are Accepted by Buyers?

Why Does the Exact CGM Model Matter?

If you have unused continuous glucose monitoring (CGM) sensors at home, identifying which products a buyer accepts is a sensible first step.

You might have extra supplies after changing devices, adjusting your monitoring routine, or organizing items you no longer need. However, knowing the manufacturer alone may not be enough to determine whether a particular box qualifies.

Different models can have different product requirements. A buyer may list one version of a sensor without accepting every other version from the same manufacturer. Related components, such as transmitters and receivers, may also have different requirements from sensors.

That is why it helps to check three details before proceeding:

• Exact model: Identify the full product name printed on the box.
• Expiration date: Confirm that the product has not expired and meets the applicable shelf-life requirements.
• Packaging condition: Check that the product remains unopened and its original packaging is intact.

These details help you move from a general brand search to a more reliable product-level eligibility check.

Which CGM Brands and Models Are Listed?

CGM Buyers has dedicated product categories for several major CGM brands. The following table provides a starting point for identifying products to check; it should not be treated as a guarantee that every model is currently eligible.

These categories may include related devices or supplies as well as sensors. Check the individual listing to make sure it matches the exact item you own.

If you have a model that is not shown in the table, do not automatically assume that it is accepted or rejected. Search the current product listings or contact CGM Buyers to confirm whether that specific item qualifies.

What Determines Whether a Sensor Is Accepted?

A product appearing in a brand category is only the starting point. Its condition and other details may also affect eligibility.

1. The sensor must match the product listing

Read the full product name on the box, including the model or generation. Avoid relying only on the manufacturer’s name or the general appearance of the packaging.

If you have multiple models, keep them separate while checking their requirements. This reduces the chance of confusing one product with another.

2. The expiration date must meet the applicable requirements

Locate the expiration date printed on the original packaging. If you have several boxes, check each one individually because the dates may differ.

CGM Buyers’ general requirements state that CGM supplies must be unopened and unexpired. Products approaching expiration may also have specific eligibility considerations, so confirm the requirements for your exact item before shipping.

If a product has already expired, see Can I Sell Expired CGM Sensors? for guidance on that separate situation.

3. The original packaging must be in acceptable condition

Inspect the box for broken seals, moisture, stains, significant crushing, or other damage. Make sure the product name and expiration date are readable.

An unopened sensor is not automatically eligible if its packaging does not meet the buyer’s requirements. Keep the original labels intact and avoid altering the box.

Use this sensor packaging inspection guide for a more detailed check before preparing your supplies.

4. The item must be the type of product the buyer accepts

A CGM system may include sensors and other components, but these items are not interchangeable.

For example, a receiver or transmitter should not automatically be submitted under a sensor listing. Confirm the product type and review its individual requirements before including it in a shipment.

How to Identify Your Sensor Before Checking Eligibility

If you are unsure which model you have, follow this simple process.

Step 1: Find the product name. Look at the original box and identify the manufacturer and full model name.

Step 2: Confirm the product type. Determine whether you have a sensor or a related component.

Step 3: Check the expiration date. Record the date printed on each box instead of estimating it from the purchase date.

Step 4: Inspect the packaging. Confirm that the box is unopened, dry, and in good condition.

Step 5: Match the product to the listing. Compare the model name and product details with the current buyer listing.

Step 6: Resolve any uncertainty before shipping. If the model is unclear or the listing does not address your product, contact the buyer for confirmation.

This quick review can help you avoid preparing a shipment before you know whether the items meet the applicable requirements.

Can You Submit Different CGM Models Together?

You may have several types of supplies in the same drawer or storage container. Before organizing them for shipment, create a separate group for each product type and model.

For example, if you have two boxes of one sensor model and three boxes of another, record each group separately. Add the quantity, expiration date, and packaging condition to your inventory list.

This makes it easier to check eligibility and provide accurate product information.

Use a simple checklist:

• Identify the full model name on each box.
• Count the unopened boxes.
• Record each expiration date.
• Check the condition of the packaging.
• Confirm the current eligibility requirements.
• Separate any products that need clarification.

Do not assume that every item in a mixed shipment qualifies just because one product does. Check each type individually before packing.

How to Choose a Buyer for Your Supplies

Once you have identified your products, look for a buyer that clearly explains its process and requirements.

Before proceeding, check whether the buyer:

• Provides current product listings.
• Explains how to identify the correct model.
• States its expiration and packaging requirements.
• Provides clear instructions for preparing and shipping products.
• Explains how product evaluation and payment work.

Clear information makes it easier to understand the process before spending time preparing a package.
