Sending your inventory to Amazon FBA doesn’t have to be complicated – even when you’re combining multiple SKUs in a single box. Over the past four years of selling on Amazon Germany, I’ve shipped thousands of units across hundreds of SKUs. And one of the most common questions I get from new sellers is: Can I mix different products in one box?
The short answer is yes – but only if you do it correctly. One small mistake in labeling, packaging, or setup can lead to rejected shipments, lost inventory, or unnecessary fees.
In this guide, I’ll walk you through exactly how to prepare, label, and ship multiple items in one box – the right way. No guesswork. No confusion. Just clear, actionable steps that align with Amazon’s current policies and best practices.
Let’s break it down.
1. Can You Mix Different Products in One Box?
Yes – absolutely.
You can combine as many different SKUs as you want in a single box, whether it’s 2 items or 200. Amazon allows mixed-SKU shipments as long as each product is properly labeled and declared in your shipment plan.
The key is consistency:
Every unit must have a valid FNSKU label applied.
The box must meet Amazon’s size and weight requirements.
You must accurately declare the contents in Seller Central.
For example, if you’re sending 10 units of Product A and 15 units of Product B in one box, Amazon’s system needs to know exactly what’s inside before it arrives. That’s why your shipment summary must reflect the correct quantities per SKU.
This flexibility is a huge advantage – it helps you consolidate shipments, reduce shipping costs, and get inventory live faster.
2. Where to Print Amazon FNSKU Labels (Step by Step)
Printing your FNSKU labels is simple once you know where to go.
Log in to your Amazon Seller Central account and follow these steps:
Go to Inventory > Manage Inventory
Select the products you want to restock
Click Actions > Print Item Labels
Choose your label format (e.g., 2.25″ x 1.25″)
Select the number of labels per SKU and click Print
Amazon will generate a PDF file with all your labels. Open it, and make sure your printer settings match the label size. I use a Munbyn thermal label printer – it’s reliable, affordable, and integrates seamlessly with Amazon’s label format.
Pro tip: Always print one label per unit, even if you’re shipping multiple quantities of the same item. Each unit must be scannable upon arrival at the fulfillment center.
3. Where to Place the FNSKU Label on Your Product
This is where many sellers make avoidable mistakes.
The FNSKU label must be clearly visible and scannable. Here’s how to do it right:
- For boxed products: Place the label directly over the manufacturer’s barcode. This prevents confusion and ensures Amazon scans the correct identifier.
- For poly-bagged or shrink-wrapped items: Apply the label on the outer surface of the bag. Make sure it’s flat and not folded or creased.
- For bubble-wrapped items: Attach the label to the flattest part of the wrap. Avoid placing it over air pockets.
Amazon’s scanners need a clean, unobstructed surface to read the barcode. If the label is crumpled, covered, or partially torn, your inventory may be rejected.
One thing I always emphasize: never place the FNSKU label inside the packaging. It must be on the outside – every time.
4. Do You Need to Bubble Wrap, Poly Bag, or Box Each Item?
This depends entirely on your product type.
Amazon doesn’t require every item to be individually boxed – but you must protect your inventory from damage during transit.
Here’s how I decide:
- Fragile items (glass, ceramics): Double protection. I use bubble wrap first, then seal in a poly bag. For extra safety, I add corner protectors or foam inserts.
- Liquid products (creams, sprays): Always seal in a leak-proof poly bag. I also include absorbent padding inside the outer box in case of leakage.
- Small or lightweight items: A poly bag is usually sufficient. Just make sure the FNSKU label is attached and the seal is secure.
- Sturdy boxed items: Often, no additional wrapping is needed – just apply the FNSKU label over the original barcode.
The golden rule? Use common sense. If the item could break, leak, or get damaged in transit, protect it. Overpackaging is better than underpacking.
5. Can You Deliver Boxes to Amazon Warehouses Yourself?
No – and this is a hard rule.
Even if you live near an Amazon fulfillment center, you cannot drop off inventory in person. Amazon uses a centralized logistics system that assigns inbound shipments to specific warehouses based on inventory needs, location, and capacity.
When you create a shipment in Seller Central, Amazon generates a shipping label with a designated destination – which might not be the closest warehouse to you. In my experience, I’ve shipped from Hamburg to fulfillment centers in Poland and the Czech Republic.
All inbound shipments must go through an approved carrier. Attempting to hand-deliver your boxes will result in rejection.
So save yourself the trip – schedule a carrier pickup or drop your boxes at a courier service like DHL, UPS, or Hermes.
6. Do Small Poly Bags Need Suffocation Warnings?
Generally, no – not if they’re too small to pose a risk.
Amazon’s suffocation warning requirement applies to poly bags with an opening of 5 inches (12.7 cm) or larger. If your bag is smaller than that, a warning label isn’t mandatory.
For example:
- An 8×6 cm poly bag? No warning needed.
- A large 30×20 cm bag? Yes – include a suffocation warning.
I keep pre-printed bilingual warnings (English and German) on hand and attach them to qualifying bags. You can download the official template from Amazon’s packaging guidelines and print them on 4×6 inch paper.
This isn’t just compliance – it’s safety. Especially for products that might end up in households with children.
7. Can You Print Small Barcodes for Tiny Products?
Yes – and you should.
Amazon allows FNSKU labels as small as 2.25″ x 1.25″, which works perfectly even for credit card-sized or pen-like items. The key is using the right printer and label stock.
If your product is very small:
- Use a thermal label printer for precision
- Ensure the barcode is fully legible and not stretched
- Test scan the label with a smartphone app before shipping
I’ve successfully labeled items as small as keychain flash drives and mini cosmetic tools. As long as the barcode is scannable, Amazon will accept it.
Just remember: no stickers inside packaging, and no overlapping labels.
8. How to Handle Fragile and Liquid Items
Protecting fragile and liquid items is non-negotiable.
For glass bottles, spray nozzles, or cream tubes, here’s my go-to method:
- Wrap the item in bubble wrap (use large-bubble wrap for better cushioning)
- Seal it in a poly bag (especially for liquids – prevents leaks)
- Place it in a rigid box with at least 1 inch of padding on all sides
- Mark the box as “Fragile” and “This Way Up” (though Amazon doesn’t always honor these, it helps)
I also avoid overfilling boxes. A tightly packed shipment increases pressure and risk of breakage. Leave some room for cushioning material like air pillows or foam.
And never ship liquids without a secondary containment layer. A single leak can ruin an entire pallet.
9. Who Does the Final Packaging for Customers?
Amazon handles the final packaging – not you.
Even if you send a product in its original retail box, Amazon will almost always repackage it in their own branded box before shipping to the customer.
This means:
- Your prep work is about protection and compliance, not presentation
- You don’t need to worry about how the customer unboxes it
- Amazon’s packaging team ensures a consistent unboxing experience
In my experience, 9 out of 10 shipments get repackaged. So focus on making your items durable and scannable – not pretty.
10. What’s the Difference Between the FBA Box Label and Carrier Label?
Two labels. Two purposes.
When you create a shipment, Amazon generates:
- FBA Shipment Label (for Amazon’s internal use)
- Carrier Shipping Label (for the courier)
Here’s how they work:
- The FBA box label tells Amazon:
Which fulfillment center the box is going to
Which shipment it belongs to
Your seller information
- The carrier label tells the courier:
Pickup and delivery addresses
Tracking number
Shipping method and cost
Both labels must be affixed to the same side of the box, clearly visible and not obstructed. I always use clear shipping tape to protect them from moisture and tearing.
Never remove either label – they’re both essential for a successful delivery.
Frequently Asked Questions (FAQs)
Can I use regular printer paper for FNSKU labels?
Technically yes, but it’s not recommended. Paper labels can tear, smudge, or fall off. Use thermal or waterproof adhesive labels for reliability.
What happens if I send a box with unlabeled items?
Amazon will likely reject the entire shipment. Each unit must have a scannable FNSKU label. Rejected inventory delays your listing and may incur return fees.
Do I need to include a packing slip inside the box?
No. Amazon doesn’t require packing slips. All information is digital and linked to your shipment ID. Save paper – leave it out.
