For US FBA shipments in 2026, sellers must ensure their products are packed, prepped, and labeled correctly before Amazon receives them. Amazon ended its US FBA prep and item-labeling service on January 1, 2026. This means sellers must prep items themselves or use a third-party service before sending products to Amazon.
Prep rules can differ by SKU. Because of this, always check Seller Central Prep Guidance before shipping your inventory.
This guide breaks Amazon FBA packaging requirements into three simple parts: the product itself, the barcode or label on the product, and the shipping box or pallet used to send it to Amazon. If you want to understand how FBA works, start with Fulfilled by Amazon (FBA) basics.

What Changed in Amazon FBA Packaging Requirements Since 2024/2025?
Two important changes mean that many older FBA packaging checklists are no longer fully correct. One change is about who does the prep and labeling. The other change is about the maximum size of an inbound FBA shipping box.
| Older guidance you may still see | Current 2026 operating position | What to do now |
|---|---|---|
| Amazon can prep or label FBA inventory for a fee. | For US FBA shipments, Amazon stopped offering FBA prep and item-labeling services starting Jan. 1, 2026. | Add prep and labeling to your supplier, warehouse, or 3PL process before shipping. |
| Use a 25-inch maximum side as the standard FBA inbound box limit. | Amazon announced a 36 x 25 x 25 inch, 50 lb maximum for US FBA inbound boxes effective June 20, 2025. This applies to the shipping carton, not the retail product package. | Measure the final shipping carton and check the latest shipping and routing rules for any exceptions. |
| Treat Frustration-Free Packaging as the current seller program name. | Amazon now mainly uses Ships in Product Packaging (SIPP). | Think about SIPP only after your packaging already meets Amazonโs protection, compliance, and certification rules. |
Amazon can change prep rules and shipping rules at different times. Before you prepare a large shipment, compare your process with Amazonโs current Packaging and prep requirements and check the SKU-level Prep Guidance inside Seller Central.
First, Separate Unit Prep, Barcodes, and Inbound Shipping Boxes
Many FBA mistakes happen because sellers apply a rule to the wrong part of the shipment.
The product itself may need a poly bag or bubble wrap. The barcode tells Amazon which product it is. The outer shipping box has separate rules for labels, size, and weight.
One shipment can have requirements for all three at the same time.
| Layer | What it covers | Seller checkpoint |
|---|---|---|
| 1. Unit-level product prep | The actual product or set Amazon receives and stores. | Protect and contain the product. Add required prep such as bagging, bubble wrap, set markings, leakage protection, or visible expiration dates. |
| 2. Item identification | The barcode Amazon scans to identify and track the product. | Choose the correct manufacturer or Amazon barcode and make sure it stays readable after prep. |
| 3. Inbound carton / pallet | The outer box or pallet used to send products to Amazon. | Follow current shipping rules, apply the FBA Box ID label, remove old barcodes, and make sure the shipment matches Send to Amazon. |
This difference is important when you see a size or weight rule.
For example, the 36 x 25 x 25 inch limit applies to the inbound shipping carton. It does not mean every retail product package must be smaller than those dimensions. Product-specific prep rules still apply to the product inside the box.
Core FBA Unit Packaging Requirements
Start with the sellable product itself.
Amazonโs July 2026 FBA prep guide says the product needs to stay secure, protected, and easy to identify while Amazon receives and handles it. The basic goal is simple: make sure the product is fully contained before adding any extra prep required for that specific SKU.
See Amazonโs 2026 FBA prep, packaging, and labeling guide for Amazonโs current public guidance.
- Keep each sellable product inside one secure package. Parts that belong together should not become separated during shipping or handling.
- If several items are sold together as one product, keep them together and add a label such as โSold as setโ or another Amazon-accepted marking.
- Keep the correct barcode easy to scan after all prep is finished. If bubble wrap or another layer covers the original barcode, put the required scannable label on the outside.
- Individual products and case-packed products are not the same thing. A carton containing several products does not make those products one sellable set unless the listing and packaging say they are sold together.
- Do not assume every product needs an FNSKU or must pass a 3-foot drop test. These requirements only apply in certain situations.
After checking these basic rules, check the prep category Amazon gives to the SKU.
If more than one rule applies, follow all of them. For example, a liquid in a glass bottle may need both leakage protection and fragile-product protection.
Product-Specific Prep Requirements - Use a Decision Matrix
Amazon Prep Guidance is the final place to check the rules for each SKU.
The table below gives you a simple idea of what may be required for different product types. It should not replace the rules shown in Seller Central.
| Product / condition | Likely prep focus and critical check | Seller Central checkpoint |
|---|---|---|
| Bagging / poly bags | Bagging is often used for products that need protection or containment, such as apparel, textiles, baby products, plush products, jewelry, powders, and small items. A suffocation warning is required when the bag opening is 5 inches or larger when measured flat. Do not use a blog as the final source for current film thickness. | Check the SKU prep category and the latest sealing, warning, scanability, protrusion, opacity, and material rules in Seller Central. |
| Fragile / glass / ceramics | Products may need bubble wrap, a protective box, or another approved method. A 3-foot drop test applies in some fragile or bubble-wrap situations, but not to every FBA product. | Check the exact prep method and current drop-test requirement for the SKU. |
| Perforated or open-sided retail boxes | If the product can fall out or is exposed through openings, Amazon may require extra protection. | Check whether the product needs bagging, over-boxing, sealing, or another form of protection. |
| Liquids / leakage risk | Liquids must be packed so they do not leak during storage and shipping. Depending on the product, this may involve secure caps, seals, bags, or secondary packaging. | Check the current leakage-prevention instructions in Seller Central. |
| Sharp items | Sharp edges or points should not be exposed where they could damage another product or hurt someone handling the item. | Check the required protection method and make sure the barcode is still visible. |
| Apparel / textiles / plush | These products are commonly bagged to keep them clean and protected. Footwear also needs to stay fully contained. | Check current bagging and warning rules for the exact product type. |
| Small/loose items | Small or loose components must remain secured as one sellable unit so parts cannot separate during handling. | Check whether the SKU requires bagging, tape, banding, or another securing method. |
| Sold-as-set / multipacks | Products sold together need to stay together and should be clearly marked so Amazon does not separate them. | Check the listing quantity, set markings, and any other prep requirements. |
| Expiration-dated products | Expiration dates must remain visible. If a bag or bubble wrap covers the original date, the date should also appear on the outside of the prep. | Check the latest expiration, shelf-life, barcode, and carton requirements for the ASIN. |
Poly-bag warnings: measure the opening flat
For the US rule referenced in Amazon Seller Central guidance, the suffocation-warning requirement depends on the size of the bag opening when it is measured flat.
A warning is required when the opening is 5 inches or larger.
This is more accurate than simply saying โbags over 5 inches.โ
Because Amazonโs public sources currently show different information about film thickness, this article does not give a thickness number. Check the latest logged-in Packaging and prep requirements page before ordering or producing poly bags.
Drop tests are conditional, not universal
Not every FBA product needs to pass a 3-foot drop test.
Amazon uses this test only in specific prep situations. Amazon staff guidance has mentioned it for fragile or bubble-wrapped products and some perforated or open-box products.
Do not make the 3-foot drop test a rule for every product.
If Seller Central gives your SKU a different prep requirement, follow that requirement instead.
Expiration-dated inventory needs an extra visibility check
Products with expiration dates need an extra check before shipping.
The date should not become hidden after you add a poly bag, bubble wrap, or other protection. Amazon staff guidance says that when extra prep covers the expiration date, the date needs to remain visible on the outside.
Check Amazonโs expiration-dated FBA guidance, and then confirm the latest ASIN-level rules before shipping.
FBA Barcodes and Labels - Manufacturer Barcode or Amazon Barcode?
Not every FBA product needs its own FNSKU label.
Amazonโs July 2026 seller guide says manufacturer barcodes are the default option for eligible products unless the seller changes the barcode setting or Amazon requires an Amazon barcode.
The easiest way to think about it is simple: first check which barcode your product can use. Then create the correct label.
| Barcode path | When it applies | Operational check |
|---|---|---|
| Manufacturer barcode | Used when the inventory is eligible and your product/account settings allow it. Common examples include UPC, EAN, JAN, and ISBN. | Confirm eligibility and barcode settings before creating shipment instructions. |
| Amazon barcode / FNSKU label | Used when Amazon requires an Amazon barcode or when your inventory is set to use one. | Put the correct label on the correct product and make sure other barcodes do not cause scanning problems. |
| Transparency code | A separate authentication code used by brands enrolled in Transparency. | Do not cover the Transparency code with another label. |
If you use a manufacturer barcode, check Amazonโs manufacturer-barcode help.
If you use an Amazon barcode, check Amazon-barcode help for the current rules.
Label placement and scanability
Amazonโs 2026 public guidance says Amazon barcode labels should be placed on a smooth, flat surface.
Do not place the barcode over a corner, curved area, or edge.
If bubble wrap, a bag, or another type of prep covers the original barcode, put the scannable label on the outside of the finished package.
Amazon also says damaged or photocopied labels are not accepted.
Your quality check can be simple. After you add all bags, seals, wraps, bands, or other prep, scan the finished product.
Make sure the correct barcode can be read easily. Also make sure another product barcode can't be accidentally scanned instead. Transparency codes must remain visible and uncovered.
Inbound FBA Shipping Box and Pallet Requirements
The rules in this section apply to the outer box used to send products to Amazon.
They do not apply to the retail package inside that box.
Amazon announced that starting June 20, 2025, the standard maximum size for US FBA inbound shipping boxes is 36 x 25 x 25 inches and 50 lb.
This replaced the older 25-inch maximum-side guidance still found in many older articles.
Use these numbers as a shipping-box check, but always confirm the latest shipping and routing requirements in Seller Central before creating a shipment.
If one product cannot fit inside the standard size limit, do not automatically use an old exception from another article. Check Seller Central for the current exception.
| Carton / pallet check | Current operating rule | Before pickup |
|---|---|---|
| Carton construction | Use a strong, fully closed shipping carton that protects the products inside. | Check Amazonโs latest carton and packing-material rules. |
| Old external barcodes | Remove or cover old shipping barcodes before reusing a box. | Make sure an old shipment barcode cannot be scanned. |
| FBA Box ID label | Every shipping carton needs the correct FBA Box ID label generated for the shipment. | Match each label to the correct physical box and shipment. |
| Dimensions and weight | Standard US FBA inbound maximum announced: 36 x 25 x 25 inches and 50 lb. | Measure and weigh the finished shipping carton. |
| Palletized freight | Pallet shipments have additional pallet labels and shipping rules. | Follow the current pallet instructions in Seller Central. |
Before handing your shipment to the carrier, compare it with Amazonโs current FBA shipping and routing requirements and the Send to Amazon workflow.
The number of boxes, box contents, labels, dimensions, and weight should match the shipment you are actually sending.

2026 Amazon FBA Packaging & Prep Checklist: Use the checklist above as your main working checklist. A dated one-page PDF can use the same checks for suppliers, warehouses, and 3PL teams. However, always use the live article and Seller Central for the latest rules.
What Happens If Packaging or Prep Is Non-Compliant?
Packaging mistakes can create real problems.
Amazonโs current public guidance says products that do not meet prep rules may be refused, returned, or repackaged. Sellers may also have to pay the related costs.
Incorrect prep can also lead to delays, damaged inventory, products that Amazon cannot properly identify, or extra work before the inventory can be sold.
There is also an important 2026 reimbursement rule. Amazon staff said that shipments created after January 1, 2026, that arrive without the required prep or item labeling will not qualify for reimbursement if the affected inventory becomes damaged or untraceable.
This makes pre-shipment checking important for more than warehouse organization. It can also affect reimbursement eligibility.
If your inventory has already been affected, use the right guide for the problem. Check FBA reimbursement rules and claim workflow for reimbursement issues, or learn how to reduce FBA returns caused by damage if poor packaging is causing customer returns.
Reduce Packaging Cost Without Breaking Compliance
Do not reduce packaging just to save money unless the product will still be protected and Amazon-compliant.
A smaller package may reduce packaging material, dimensional weight, fulfillment fees, or shipping cost. However, those savings are not useful if the smaller package causes more damage, leaks, returns, or receiving problems.
Start by measuring the final packaged size and weight.
Use the Amazon Revenue Calculator for FBA profit analysis to compare the old and new packaging.
Also include changes in materials, labor, Amazon fees, and shipping costs.
For more help, see how to reduce FBA fees without compromising product protection and reduce Amazon shipping costs.
Here is a simple example.
Suppose better packaging reduces fulfillment and shipping costs by $0.30 per unit. The new packaging material costs an extra $0.05 per unit.
Your net savings would be $0.25 per unit.
At 8,000 units per month, that's $2,000 per month.
This is only an example. Use your own product numbers before making a packaging decision.
Consider SIPP only when the package is ready for it
Ships in Product Packaging (SIPP) allows eligible products to ship in their own certified packaging without extra Amazon packaging.
Amazon currently shows a fulfillment-cost discount of $0.04 to $1.32 per certified item.
SIPP can reduce packaging materials and costs, but it shouldn't be your first concern.
First, make sure the packaging protects the product, follows Amazonโs rules, and provides a good customer experience. Then consider SIPP certification.
Branded Packaging and Product Inserts - Compliance First
You can use branded packaging with FBA as long as it does not block required labels, affect barcode scanning, reduce product safety, or break Amazon prep rules.
The same idea applies to product inserts.
Use inserts to help customers use the product. Do not use them to get around Amazonโs review or customer-contact rules.
- Safer insert content includes instructions, care information, setup help, troubleshooting tips, a neutral thank-you message, or basic information about your brand.
- Do not ask only for positive reviews or tell customers not to leave negative reviews.
- Do not offer discounts, refunds, gifts, or other rewards in exchange for reviews.
- Do not direct buyers off Amazon for customer service when the purpose is to prevent or discourage negative reviews.
- Do not collect customer email addresses for product registration.
Amazon staff recently explained these rules again in product-insert and off-Amazon contact guidance.
Check the latest Seller Central policy before printing a large number of inserts, especially if your insert includes a QR code, URL, warranty information, registration process, or review request.
Keep FBA Prep Accurate as Your Catalog Scales
A good FBA packaging process should make everyday work easier while still allowing for different rules for different products.
Create standard checks that your warehouse, supplier, or 3PL can follow. At the same time, remember that Amazon may require different prep for individual SKUs.
Use the three-layer model, the product prep table, and the pre-shipment checklist to find problems before your cartons leave your warehouse.

FAQs About Amazon FBA Packaging Requirements
1. What are the Amazon FBA packaging requirements in 2026?
For US FBA shipments, think about three parts.
First, prepare the sellable product based on its required prep category. Second, use the correct manufacturer barcode or Amazon barcode. Third, prepare the shipping carton or pallet using Amazonโs current inbound shipping rules.
Since January 1, 2026, Amazon no longer provides US FBA prep and item-labeling services. Your products must arrive prepped and labeled.
Always check SKU-specific Prep Guidance before shipping.
2. Did Amazon FBA packaging requirements change from 2024 or 2025?
Yes.
Two changes are especially important.
Amazon stopped offering US FBA prep and item-labeling services on January 1, 2026.
Amazon also announced a new standard maximum inbound box size of 36 x 25 x 25 inches and 50 lb starting June 20, 2025.
Do not keep using older 25-inch box guidance without checking Seller Central.
3. Does Amazon still prep and label FBA inventory for sellers?
No, not for US FBA shipments created on or after January 1, 2026.
Sellers must now complete prep and item labeling before the products reach Amazon.
You can do this yourself or use a third-party provider.
4. What is the maximum box size and weight for an FBA shipment?
Amazonโs June 2025 US announcement gives a standard maximum inbound shipping-box size of 36 x 25 x 25 inches and 50 lb.
This rule applies to the shipping carton, not the retail product package.
Check Amazonโs current shipping and routing help if you think your shipment qualifies for an exception.
5. Do all FBA products need an FNSKU label?
No.
Amazonโs July 2026 seller guide says eligible inventory can use manufacturer barcodes by default unless the seller changes the barcode setting.
Some products or settings require an Amazon barcode that contains the FNSKU.
Always check eligibility before creating your labels.
6. When does an FBA poly bag need a suffocation warning?
Amazonโs US guidance uses the size of the bag opening when measured flat.
A suffocation warning is required when the opening is 5 inches or larger.
Check the current Packaging and prep requirements page before production for the latest warning format and other bag requirements.
7. Does every FBA package have to pass a 3-foot drop test?
No.
The 3-foot drop test applies only to certain product and packaging situations, including some fragile, bubble-wrapped, or perforated-box products.
It is not a rule for every FBA product or shipping box.
Follow the prep method Amazon assigns to your SKU in Seller Central.
8. Where can I find Amazonโs official packaging and prep requirements help page?
Use the Seller Central Packaging and prep requirements page and the Prep Guidance shown for your SKU.
You may need to log in to Seller Central.
If information in a blog or forum is different from Seller Central, use the current Seller Central guidance as the final source.
9. Is there an Amazon FBA packaging and prep requirements PDF?
A PDF can be useful as a simple checklist, but Seller Central should remain your main source for current Amazon rules.
SalesDuoโs dated 2026 checklist can help warehouse, supplier, or 3PL teams follow the basic checks.
10. Can I use branded packaging or product inserts with FBA?
Yes, in some cases.
Your branded packaging still needs to meet Amazonโs packaging, prep, barcode, and scanning requirements.
Product inserts can include instructions, care information, setup help, or a neutral thank-you message.
They should not manipulate reviews, offer rewards for reviews, move customer support away from Amazon to avoid negative reviews, or collect customer email addresses for registration.
Always check the latest Amazon policy before printing inserts.
