Overview

When selling multi-item products through Fulfillment by Amazon, sellers must follow specific packaging and labeling rules for items sold as a single unit. Whether you're bundling a two-pack, a gift set, or a multi-component product, Amazon requires that all pieces be securely packaged together and properly identified with a single barcode. Failing to meet these requirements can result in preparation defect fees charged to your account.

Key Points / What Sellers Need to Know

• All set items must be packaged together — Two or more items sold as one sellable unit need to be contained in a bag, box, or bubble wrap before shipping to fulfillment centers.
• Shrink wrap is acceptable — Heat-sealed shrink wrap can be used as an alternative packaging method to keep set components together.
• A "Sold as Set" label is required — Every set must include a visible sticker reading "Sold as set," "Ready to ship," or "This is a set. Do not separate" (or similar wording).
• One scannable barcode per set — The set must display a single item identifier barcode for the set ASIN, and all other barcodes on individual components must be covered to prevent incorrect scans.
• Non-compliance triggers fees — Products that arrive at fulfillment centers without proper set preparation may incur a preparation defect fee.

What Qualifies as a Set

Amazon defines a set as any sellable unit containing two or more individual items. This includes multi-packs (such as a three-pack of phone cases), bundled items (like a shampoo and conditioner sold together), accessory sets, and gift collections. The key distinction is simple: if the listing is for multiple physical items sold under one ASIN, it qualifies as a set and must follow these preparation rules. Sellers should review their catalog to identify any listings that fall into this category, as even items that seem obviously connected still require formal set packaging.

Packaging Requirements

Sellers have several options for containing set items: poly bags, boxes, bubble bags, bubble wrap, or heat-sealed shrink wrap. The chosen method must keep all components securely together and prevent movement or breakage during transit and warehouse handling. Amazon's packaging decision trees — covering bagging, boxing, and bubble wrap requirements — can help sellers determine which material is most appropriate for their specific product type. Once items are placed in their packaging, the container must be sealed with tape, an adhesive strip, or glue to ensure nothing separates during fulfillment operations.
