If you’ve ever sold continuous glucose monitoring (CGM) sensors — like Dexcom G6 or G7 — you know how valuable they are. These small devices help diabetics manage blood sugar with precision. But when you decide to sell your extra sensors, one big question always comes up:
“How do I mail CGM sensors safely without damaging them?”
That concern is completely valid. CGM sensors are sensitive medical devices, and improper shipping can lead to crushed boxes, damaged packaging, or even disqualification from resale.
The good news? Mailing them safely is easy when you follow a few key steps — and CGM Buyers makes the process simple and secure.
In this guide, we’ll walk you through exactly how to mail CGM sensors so you can sell confidently and get paid quickly.
Why Safe Mailing Matters
Shipping your CGM sensors safely isn’t just about protecting your payout — it’s about maintaining quality and helping protect your products during shipping.
We follow clear product eligibility and purchasing guidelines to help ensure every order is reviewed consistently. That means:
- Only sealed, undamaged products are accepted.
- Products must arrive in mint condition.
- Each label is linked to a specific order to track shipments securely.
If your package arrives damaged, tampered with, or opened, it may not meet our purchasing requirements, which is why proper packaging is important.
“Think of your sensors like valuable electronics — you’d never toss an iPhone in an envelope, right? Your CGM supplies deserve the same care.”
Myth vs. Fact: Mailing CGM Sensors Safely
Myth 1: I can just toss my sensors in a padded envelope.
Fact: CGM sensors should always be shipped in a sturdy box with padding. Envelopes are too thin and increase the risk of crushing or tearing.
Myth 2: I can use my own label to ship faster.
Fact: Each CGM Buyers label is tied to your order for tracking and processing. Using your own label can delay or cancel your payment.
Myth 3: The post office won’t allow me to mail medical items.
Fact: You can ship sealed CGM sensors through USPS when properly packaged
Myth 4: Removing pharmacy labels helps the buyer.
Fact: Don’t tamper with pharmacy labels — you may damage the box. The team will remove and destroy labels safely to protect your privacy.
How to Mail CGM Sensors Safely — Step by Step
Ready to mail your Dexcom sensors? Here’s a complete walkthrough to make sure your package arrives in perfect condition.
Step 1: Review Your Items Before Shipping
Before you package anything, take a few minutes to inspect your sensors.
Check Expiration Dates:
Make sure all products meet expiration date guidelines advertised on each product page
Confirm the Condition:
- Boxes should be sealed and untampered.
- Boxes should be clean and free from stains.
- Avoid writing or marking on the boxes.
Don’t Remove Labels:
If your sensors have pharmacy stickers, leave them on. Removing them may tear the packaging and affect product evaluation.
Group Similar Items:
If you’re selling multiple Dexcom G6 or G7 sensors, group them by model for easier inspection when received.
Step 2: Use the Correct Shipping Label
Once you place your sales order, you’ll receive a pre-approved shipping label for your shipment.
Each label is unique to your order, ensuring your package is tracked, logged, and processed correctly.
Do not reuse labels from old orders.
Reusing an old label can delay your payment or cause your order to be lost in processing.
Pro Tip: Print your label clearly on standard paper and tape it flat on the top of your shipping box.
Step 3: Choose the Right Packaging Materials
Using strong, protective materials is the secret to successful shipments.
Here’s what you’ll need:
- A rigid shipping box (not a bubble mailer).
- Bubble wrap or packing paper for cushioning.
- Plastic sandwich bags to protect each product from moisture.
- Packing tape to secure all sides of the box.
Avoid:
- Padded envelopes (too weak).
- Old boxes with holes or creases.
- Newspaper (can transfer ink stains).
Safety Rule: Always package your CGM sensors carefully to help protect them during shipping. That’s how you guarantee a smooth inspection.
Step 4: Pack Your CGM Sensors Properly
Here’s the ideal packing method for maximum safety:
- Wrap each box individually in bubble wrap or seal it in a plastic bag.
- Place the wrapped boxes snugly inside your shipping box.
- Add extra padding around edges to prevent movement.
- Seal all seams of the box with strong packing tape.
When you shake your box gently, you shouldn’t hear movement. That’s how you know it’s packed tight enough.
Step 5: Ship Within 7 Days of Your Order
CGM Buyers asks all sellers to mail their products within 7 days of placing an order.
This helps ensure your order is processed without unnecessary delays.
“Mail your sensors as soon as possible to help keep the process moving smoothly.”
Step 6: Track Your Shipment
After dropping off your package, keep your tracking number handy.
You can check your package’s progress at any time using the carrier’s website. Once your sensors are received and verified, you’ll get an email from us confirming processing and payment.
All payments are issued within 2 business days after receiving and inspecting your package.

Common Shipping Mistakes to Avoid
Here’s what not to do when mailing CGM sensors:
Don’t use padded envelopes. They don’t protect the boxes during shipping.
Don’t peel off labels. It can damage the packaging and reduce payout.
Don’t delay shipment. Waiting too long to ship may delay your order.
Don’t ship tampered or opened sensors. They may not meet our purchasing requirements.
Don’t reuse labels. Each label is unique to one order.
Quick Check: Box sealed? Label correct? Packed tightly? If yes, you’re good to go.
Example of a Perfect Shipment
Let’s visualize it:
- Box: Small USPS Priority Mail box.
- Inside: 3 Dexcom G7 sensor boxes, each in a clear plastic bag.
- Padding: Bubble wrap around edges and top.
- Seal: Taped securely on all sides.
- Label: Printed clearly on top — no folds or obstructions.
Result: The package arrives undamaged, passes inspection, and your order can be processed.
