Delivering products to Amazon FBA is a delicate task that involves packaging, and poly bags are one of the most important components of it in most cases. We, being a major provider of supply chain in China at BM Supply Chain, have assisted hundreds of sellers to bypass these regulations to prevent expensive errors. Our Amazon fulfillment services from China cover product sourcing, product inspections, warehousing, drop shipping, order fulfilment, and Amazon logistics. Having the capability of integrating resources between factories to final customers, we provide solutions such as procuring raw materials or finished goods, providing up to 30 days free storage, sophisticated warehouse systems, free API docking to enable smooth shipping, and one-stop tracking query, to simplify cash flow and allow you to concentrate on growth. Additional features such as assembly, custom wrapping, labeling, and inserts are all value-added features.
Poly bags requirements of Amazon have not changed significantly by the year 2026, but now that in-house prep services will be terminated as of January 1, sellers will have to do this themselves or have the same outsourced in a prudent manner to avoid rejections. These regulations provide safety, safeguard goods when handling and make the warehouses to be effective.
Non-compliance? Delay in receiving is expected, automatic rebagging (to a maximum of $0.15 per unit in case it is fixed by Amazon before 2026, but after? Wholesale returns), or returns. Clients have saved thousands by doing this right in China upstream.
What Are Amazon Poly Bag Requirements?
Amazon implements the policy of poly bags to avoid such risks as suffocation, safety of goods against dust or damage, and scanning of goods without difficulties in the warehouses. They are compulsory in loose, soft or multi-part products, which may contaminate or leak during transportation.
Key when: Apparel, porous toys, powders or the objects that require enclosure. Bags should be 1.5 mil in thickness, closed and transparent to be inspected on content and have warnings of suffocation in case the bag has a hole bigger than 5 inches. This assists in handling the warehouse and scanning barcodes without unpacking.
Why matter? First things first–to keep the children safe, you have to warn them first; to avoid cross-contamination, you are to bag properly. Turn a blind eye to them, and along with rejection, you’ll get post-2026 when Amazon is not ready to wait on you. Poly bagging is one step in a complete Amazon FBA inventory preparation checklist, and we incorporate it into our FBA prep to ensure that products remain compliant at BM Supply Chain.
Quick compliance checklist:
- Thickness: [?]1.5 mil.
- no opening recommended: Sealed: Heat or adhesive.
- Cavert: Reprinted, [?]5″ vacancies.
- Clear: A clear view of the contents.
- Barcode: Can be scanned through bag.
- Size: Snug fit, no excess air.
- Positioning: Lying, exposed facility.
When Your Product Must Use a Poly Bag
All the items do not require a poly bag, but most of them do to fulfill the packaging criteria Amazon has established to FBA. Apply them to the products that may soil others, have loose parts or require dust/moisture cover.
- Loose objects: The objects may be toys, accessories, hardware, and so on.
- Small parts: It contains small parts that can be dropped during the handling process.
- Clothing/soft items: appears as shirts, socks or anti-snag/ dirt materials.
- Plush or baby products: Makes use of fibers that are restricted, does not pollute.
- Products that contain a number of components: Non-boxed kits or sets.
Poly bags are used to make the warehouse run more efficiently- imagine a bag of beads that has been torn open and the bags are lying everywhere. According to our operations, approximately 60 percent of clothing deliveries demand them; miss, and Amazon may rebag at the cost of you.

Hint: scan product with scanner app before packing- we do the same in our China FBA prep center.

Squeeze-seal to prevent ruptures caused by changes in pressure. Removing unnecessary air also supports efficient packaging for Amazon FBA shipping costs by reducing avoidable parcel volume.
- Textiles that are vacuum-sealable preferably.
- Employing plush: Squeeze air out by hand.
Popped bags in trucks–restocks it cost them sellers to see.

The correct positioning makes scans uncomplicated.

Good: [1.5 mil clear bag, heat-welded, compressed flat, FNSKU sticker external, scannable, and printed in bold] t-shirt, warning printed.
Bad: Plush toy in 1 mil bag, not sealed, twist tied (not sealed), too much air in it making it puffed, barcode in its wrinkled plastic, can not scan it.
Another bad Accessory kit in foggy bag, opening untucked, none give warning, however large,–rejection waiting to occur.
These pictures of our prep experience demonstrate that little details produce a significant difference.
Poly Bags for Special Product Types
1. Clothing and Apparel

Common Poly Bag Mistakes
