Amazon FBA Packaging Requirements by Category (2026)

In this article:

Amazon's packaging requirements are not one list. They depend on what you sell. A poly-bagged t-shirt, a glass candle, a 40-pound rug, and a 12-count vitamin case each have their own rules, and Amazon can charge a prep fee or refuse a shipment when a unit arrives wrong. This guide organizes the requirements by product type so you can find yours fast. Amazon updates these specs and applies some at the ASIN level, so treat this as the map and confirm the exact requirement for your product in Seller Central before you ship. The specs below reflect Amazon Seller Central guidance as of 2026.

Product type	Key packaging requirement
Standard items	Scannable FNSKU, undamaged, survives handling
Soft goods and apparel	Transparent poly bag, suffocation warning if opening is 5 in or wider
Fragile and glass	Bubble wrap, passes a 3-foot drop test
Sharp items	Fully covered so they cannot puncture
Liquids	Leak-proof seal, secondary packaging
Oversize	Oversize prep, Team Lift label over 50 lb
Multi-packs and sets	Bundled, "Sold as Set" label, one FNSKU
Case-packed	Identical units per box, quantity matches the plan

How Amazon decides your prep requirements

Amazon sets some requirements by category and some at the ASIN level. Category rules cover the basics: soft goods get poly-bagged, fragile items get protected, sharp items get covered. On top of that, an individual ASIN can carry its own prep guidance in Seller Central, which is why two products in the same category sometimes need different handling. Always check the specific ASIN rather than assuming the category rule is the whole story.

Standard product packaging requirements

A standard, non-fragile item needs one thing above all: a single scannable barcode. Apply the FNSKU over the manufacturer barcode so only one code shows, and make sure the unit is undamaged and can survive normal handling in the warehouse. If the product has its own retail packaging, that packaging has to stay intact and closed so the unit arrives sellable. Expiration-dated products carry extra rules: the date has to appear on the unit and the master carton, and Amazon requires a minimum remaining shelf life at check-in, so confirm the current window in Seller Central.

Poly bag requirements

Poly bags have to be transparent and at least 1.5 mil thick, with the barcode scannable through the bag or on a label applied to the outside. Any bag with an opening of 5 inches or more, measured flat, needs a printed suffocation warning in a legible size. The bag has to be sealed, and it should fit the product without a lot of loose material. Apparel, textiles, plush, and other soft goods almost always fall under poly bag rules.

Bubble wrap and fragile item requirements

Fragile items, including glass and ceramics, have to be wrapped well enough to survive a 3-foot drop onto a hard surface without breaking. That usually means individually bubble-wrapping each unit and, for multi-piece items, adding dividers so pieces do not knock together. Amazon treats a broken unit at receiving as your loss, so err toward more protection. If a fragile item also ships in a box, the box itself has to pass the drop test and stay closed.

Oversize product packaging requirements

Oversize units, meaning products that exceed Amazon's standard-size dimensions or weight, get their own prep and storage handling. Heavy units need enough packaging to protect them and the units around them. A carton holding a single oversize unit over 50 pounds needs a "Team Lift" label, and over 100 pounds needs a "Mechanical Lift" label, so associates handle it safely. Check the current oversize thresholds in Seller Central, since Amazon revises the size tiers.

Box size and weight limits for FBA shipments

Shipping cartons for FBA generally cannot exceed 25 inches on the longest side or 50 pounds, unless the box holds a single oversize unit that is larger or heavier on its own. Every carton needs box content information so Amazon knows what is inside, plus the FBA shipment label and the carrier label on the outside. Use sturdy boxes rated for the weight, because a crushed carton at receiving slows the whole shipment down.

Multi-pack and bundle requirements

A multi-pack or set has to arrive as one sellable unit. Bundle the components so they cannot separate in transit, label the outside "Sold as Set" or "Do Not Separate," and apply one FNSKU to the finished bundle rather than to the individual pieces. This is where sellers lose units most often: an unlabeled or unbundled set gets split at receiving and the pieces scatter across inventory.

Case-pack requirements

Case-packed inventory means each box holds the same item, in the same condition, in the same quantity, and the box configuration matches what you declare in the shipment plan. Case-packing saves prep time at scale because Amazon can receive by the case rather than the unit, but it only works when every box is identical. Set the case-pack quantity accurately in Seller Central, since a mismatch between the declared and actual count triggers a receiving discrepancy.

How to look up your ASIN's requirements in Seller Central

Open the product in the Send to Amazon or Manage Inventory flow and check the prep guidance and "Who preps" settings for that ASIN. Amazon lists whether the unit needs poly bagging, bubble wrap, a suffocation label, bundling, or special handling, and whether you or Amazon applies the FNSKU. Requirements can differ by ASIN even inside the same category, so check each product rather than copying last shipment's setup.

Using a prep center when requirements get complex

One product type is manageable. Selling across several, meaning soft goods that need poly bags, glassware that needs bubble wrap, a few oversize SKUs, and a case-packed line, means tracking four sets of rules and buying four kinds of materials. Sellers who cross categories often hand prep to a third party rather than manage it in-house.

An Amazon 3PL receives your inventory, applies the right packaging per category, labels each unit, and forwards it to Amazon, and ships your FBM and direct-to-consumer orders from the same stock.

Simpl runs Amazon FBA prep as a core service from its Austin, TX warehouse, prepping mixed-category inventory to Amazon's current spec. If you are near Austin or ship into the South Central region, Simpl's Austin prep center handles multi-category FBA prep and FBM fulfillment from one inbound shipment. Orders received before 12pm CT ship the same day, at 99.99% accuracy with any error fixed at Simpl's cost.

Frequently Asked Questions

What are Amazon's poly bag requirements for FBA?

Amazon requires poly bags to be transparent and at least 1.5 mil thick, with a scannable barcode and a secure seal. Any bag with an opening of 5 inches or more, measured flat, needs a printed suffocation warning in a legible size. The bag should fit the product without excessive loose material. Check the current spec in Seller Central, since Amazon updates the details.

What is the box size limit for FBA shipments?

Standard shipping cartons for FBA generally cannot exceed 25 inches on the longest side or 50 pounds, unless the box holds a single oversize unit that is larger or heavier on its own. Cartons over 50 pounds need a "Team Lift" label, and over 100 pounds need a "Mechanical Lift" label. Confirm the current limits in Seller Central before you pack, since Amazon adjusts them.

Does every FBA unit need a suffocation warning?

No. The suffocation warning applies to poly-bagged items where the bag opening is 5 inches or wider. Boxed items, and small bags below that threshold, do not need it. When a bag does qualify, the warning has to be printed legibly on the bag or on a label. Amazon's Seller Central help pages carry the exact wording and size.

How do I find the packaging requirements for my specific product?

Open the product in Seller Central and check the prep guidance and "Who preps" settings in the Send to Amazon or Manage Inventory flow. Amazon lists whether your ASIN needs poly bagging, bubble wrap, a suffocation label, bundling, or special handling, and whether you or Amazon applies the FNSKU. Requirements can differ by ASIN even within the same category, so check each product rather than assuming.

What happens if my FBA packaging does not meet Amazon's requirements?

Amazon can charge an unplanned-prep or labeling fee to fix the unit, hold the shipment in a problem queue while it is sorted out, or refuse and return the shipment at your cost. Beyond the fees, the delay keeps inventory you paid for out of buyable status. Prepping to spec the first time, or handing prep to a provider that does, avoids the charge and the wait.

Can a 3PL handle FBA packaging requirements for me?

Yes. A 3PL that offers FBA prep receives your bulk inventory, packages each unit to Amazon's category spec, applies FNSKU labels, builds the shipment plans, and forwards the boxes to the assigned fulfillment centers. Simpl runs Amazon FBA prep as a core service and can also ship your FBM and direct-to-consumer orders from the same inventory, so mixed-category prep and everyday fulfillment run from one warehouse.
