1. Check Sensor Quality

Inspecting the condition of your sensors is a key step to ensure buyer confidence and compliance with safety standards. Start by verifying expiration dates and assessing the overall packaging quality to determine if the sensors are suitable for resale.

Check Expiration Dates

The expiration date plays a major role in resale value. Most buyers prefer sensors with at least 4 months remaining before expiration, and some are willing to pay more for sensors with 6 months or more of shelf life left [1].

Here’s where to find expiration dates:

• Dexcom Sensors: Look for the expiration date on the outer box.
• FreeStyle Libre Sensors: Check both the sensor pack and the outer packaging.
• Note: Dexcom G6 and G7 receivers do not have expiration dates [3].

Examine Package Condition

The condition of the packaging is just as important as the sensor itself. Intact factory seals, clear labels, and legible lot numbers are essential to confirm authenticity and quality. When inspecting the packaging:

• Ensure factory seals are unbroken.
• Verify labels and lot numbers are intact and easy to read.
• Look for signs of damage, moisture, or tampering.

Record Sensor Information

Documenting sensor details is critical for an organized and smooth sale process. Take clear photos that capture the following:

• The front and back of the packaging.
• Expiration dates.
• Lot numbers.
• Factory seals.
• Any identifying markings.

Maintain detailed records for each sensor, including its quantity and condition. This information not only helps in discussions with potential buyers but also ensures you can track your inventory and confirm that all items meet the agreed-upon conditions during the sale [2].

2. Legal Requirements

To safely resell CGM sensors, compliance with FDA and state regulations is essential.

FDA and State Rules

CGM sensors are classified as medical devices by the FDA, which means their sale and distribution are subject to strict guidelines. Here's a breakdown of the key requirements:

"By using products that have not been reviewed by the agency for safety and effectiveness, patients with diabetes may be putting themselves at risk for serious injury or even death" [5].

Following these legal standards is critical to ensure compliance and user safety. Below are some safe selling practices to help meet these requirements.

Safe Selling Standards

• Verify Funding Source: Avoid selling sensors obtained through Medicare, Medicaid, or other government assistance programs [6].
• Maintain Original Packaging: Ensure factory seals and packaging remain intact.
• Follow Storage Requirements: Store sensors according to the manufacturer's guidelines.
• Document Chain of Custody: Keep detailed transaction records to comply with legal obligations.

The American Diabetes Association highlights the risks of mishandling CGM sensors:

"You could be greatly overusing or underusing insulin" because of an incorrect result. "That's where it would be a really critical health issue." – Matt Petersen, vice president of medical information for the ADA [6].

Important Safety Guidelines

• Always keep the original packaging intact.
• Store sensors as instructed by the manufacturer.
• Maintain a clear chain of custody for all transactions.
• Ensure proof of legal acquisition is readily available.

Selling unauthorized or improperly handled CGM sensors not only poses safety risks but can also lead to legal consequences. The FDA strongly discourages the sale of pre-owned or unauthorized medical devices due to their potential dangers [5].

3. Find a Reliable Buyer

After meeting all legal requirements, the next step is finding a trustworthy buyer for your diabetic test strips.

Verify Buyer Credentials

It's crucial to work with buyers who are transparent and have a proven track record. Here's what to check:

A great example of a buyer meeting these standards is Two Moms Buy Test Strips. They emphasize their dedication to sellers:

"We are committed to being the best company you can sell your diabetic test strips to, and we offer you the highest pricing, cash for test strips, with the fastest payment and best communication over any other. We actually answer our phone when you call!" [7]

Review Payment Terms

When choosing a buyer, secure and quick payments should be a priority. Look for these features:

• Transparent pricing: Upfront quotes that allow easy comparisons
• Fast payment processing: Payments issued promptly after receiving your items
• Secure transactions: Safe and reliable payment methods
• Consistent communication: Updates at every step of the process

Two Moms Buy Test Strips highlights their focus on keeping sellers informed:

"We will notify you every step of the way when you sell us your test strips so you will never have to wonder when, or if, your payment is coming." [7]

Red Flags to Watch Out For

Stay alert to potential scams or unreliable buyers. Warning signs include:

• Requests for advance payments
• Interest in government-issued supplies
• Vague or unclear pricing
• Demands to purchase shipping materials

Taking the time to verify buyer credentials and payment terms protects your efforts and ensures a smooth, secure transaction.

4. Ship Your Sensors

Package Sensors Correctly

To ensure your sensors arrive safely and maintain their quality, proper packaging is a must. Following FDA standards not only helps preserve the integrity of the sensors but also ensures compliance with shipping regulations.

Key Packaging Requirements:

• Keep sensors in their original sterile packaging with tamper-evident seals [10].
• Maintain a controlled temperature range of 35.6°F–46.4°F (2°C–8°C) [12].
• Use medical-grade materials like thermoformed plastic trays or foil pouches [8].

For outer packaging, choose rigid corrugated cardboard boxes with an ECT rating of 32 or higher. Studies show these boxes reduce sensor damage by 78% compared to standard ones [14].

Temperature Control Guidelines:

• Use insulated Styrofoam containers with 2-inch foam walls for added protection.
• Include frozen gel packs to maintain the required temperature range.
• Add temperature monitoring devices to track compliance during transit [12].

After ensuring the sensors are securely packaged and temperature is controlled, the next step is to choose a reliable shipping method.

Choose Shipping Methods

According to FDA analysis, 92% of sensor damage occurs due to poor temperature control during transit [11]. Selecting a shipping carrier with expertise in handling medical devices is essential.

Top Shipping Option:

FedEx Priority Overnight® provides several features tailored for medical shipments:

• 24/7 shipment monitoring through Priority Alert.
• Temperature-controlled packaging to maintain the required range.
• Insurance coverage of up to $150,000 per package [13].
• Real-time tracking and notifications for added peace of mind.

Labeling and Documentation:

Proper labeling and documentation are critical for safe and compliant shipping. Be sure to:

• Label the package as "Medical Device – Maintain 35.6°F–46.4°F".
• Include the FDA Unique Device Identification (UDI).
• Mark the package as Fragile Medical Device.
• Attach a detailed packing slip with LOT numbers and handling instructions [8].

To minimize risks, schedule pickups in the morning to avoid extreme temperatures. Opt for signature confirmation and adjust insurance coverage based on the shipment's value. While ground shipping is about 40% cheaper than air, it extends transit time by 2–5 days [9].

For example, Insulet Corporation reported a 41% reduction in sensor shipping losses after adopting ISTA 20-certified packaging and real-time temperature monitoring in Q2 2024 [12][15]. Following these shipping practices ensures your sensors stay safe, compliant, and ready for use.

5. Record Keeping

Save Sale Documents

Keeping thorough records of CGM sensor sales is crucial for both legal compliance and accurate tax reporting. Proper documentation not only verifies your income and expenses but also helps you avoid disputes or issues during audits.

Key Documents to Keep:

Tip: Retain these records for at least four years.

Best Practices for Documentation:

• Use a digital system to track inventory and sales.
• Take clear photos of sensor lot numbers and expiration dates.
• Keep copies of all buyer communications.
• Save transaction receipts and payment confirmations.

Report Sales Income

Tax Reporting Guidelines:

• If selling regularly, report income on Schedule C.
• Maintain clear documentation of all income and expenses.
• Keep these records for at least four years post-filing.

Potential Deductible Expenses:

• Costs for shipping materials and postage.
