Amazon Oversized Product

As an Amazon seller, you should know all about the platform's rules and regulations. Being aware of them saves you effort and money, especially if you sell non-standard products. On the one hand, selling such items may mean lower competition because only some sellers will risk selling them. On the other hand, selling non-standard products may mean more hassle.

Since oversized inventory is considered non-standard, selling it comes with its own set of challenges. This post will discuss what Amazon oversized inventory is, the different oversize tiers, how Amazon processes FBA oversize items, and the associated fees.

What Is Amazon FBA Oversized Inventory?

Oversized inventory on Amazon refers to products that exceed the standard size and weight limits. Due to irregular dimensions, these products require special handling and storage, which is why they are classified as oversized. 

Products that exceed standard limits set by Amazon are charged additional fees, and their shipping and fulfillment options differ from standard-sized products.

Amazon Oversize Tiers

Amazon has four different size tiers for oversize products, ranging from “small oversize” to “special oversize”. Each tier has its own size and weight limits. 

Breakdown of Amazon oversize tiers

Small oversize are products larger than standard-sized items, with the longest side of 60 inches, a median side of 30 inches, a length of 130 inches, and weighing fewer than 70 pounds.

‍Medium oversize are products larger than the small oversize category, with the longest side of 108 inches, a length of 130 inches, and weighing less than 150 pounds.

‍Large oversize are products larger than the medium oversize category, with the longest side of 108 inches, a length of 165 inches, and weighing less than 150 pounds.

‍Special oversize are products larger than the large oversize category weighing more than 150 pounds.

How to Determine the Product Oversize Tier?

To determine your product’s oversize tier, you must calculate its volume and weight. Amazon calculates the volume of the product by multiplying its length, width, and height. 

To identify the size tier, you must first determine the volume and dimensions of your product. Then, measure the item’s weight and dimensional weight (a calculation of the volumetric weight of a package using the package’s length, width, and height). Compare your values and the numbers in the table below to get the product size tier.

If your product’s volume exceeds the maximum for a particular size tier, it will be classified as the next highest tier. For example, if your product has a volume of 65 inches and weighs 75 pounds, it would be classified as a medium oversize product.

‍Note. Dimensional weight equals the unit volume (length x width x height) divided by 139. The dimensional weight for oversize items assumes a minimum width and height of 2 inches. For FBA, Amazon uses dimensional weight when it’s greater than the unit weight for small oversize, medium oversize, and large oversize apparel and non-apparel. For Multi-Channel Fulfillment (MCF), the dimensional weight is calculated for all small oversize, medium oversize, and large oversize items, regardless of whether the item is apparel.

Oversize product size tier examples

Below you can find some examples of products that fall into each of the size tiers.

‍Small oversize: vacuum cleaners, oversized board games, folding chairs.

Medium oversize: small furniture items, large pet carriers, exercise equipment.

‍Large oversize: televisions, kayaks, bicycles.

Special oversize: large machinery, industrial equipment, oversized furniture.

How Does Amazon Process FBA Oversized Items?

When you send an oversized product to an Amazon fulfillment center, oversized items are split from standard-size inventory into separate shipments. Oversized units are directed to a separate facility that handles oversized items. 

Amazon will then measure and weigh your product to determine its size tier and charge you the appropriate fees. Amazon may also require additional handling and packaging for oversized items, further impacting the fulfillment cost.

What Are Amazon Oversize FBA Fees?

Amazon oversize fees vary depending on the product’s size and weight tier. The fees range from $9.73/lb for small oversize products to $179.28/lb for special oversize products. They differ in dangerous and non-dangerous goods.

Storage fees for storing oversized inventory in Amazon warehouses are also higher than for standard goods. Storage fees are calculated based on the daily average volume of the space inventory occupies. The rate is based on product type, size tier, and time of year.

It’s important to note that these fees are in addition to the standard FBA fees, referral fees, and other charges that may apply to your product. As an Amazon seller, it’s essential to consider these fees when pricing your product and calculating your profit margins.

‍Tip. To accurately account for all oversized product fees, Amazon sellers use various Amazon fee calculators. One of the best Amazon profit calculators is Seller Assistant App’s FBM&FBA calculator. It helps you quickly calculate all FBA fees and expenses right on the Amazon product page.

How To Quickly Check Products For Oversize?

If you are still unsure whether the product belongs to an oversized category, it may be challenging to find that out. However, there is a way to do it fast. Seller Assistant App allows you to determine whether a product belongs to an oversized category right on the Amazon product and search pages. If a product belongs to an oversized, Seller Assistant App will give you an Oversized Product Notification. If you see the Red Box icon on your Amazon product or search page, that indicates that the product is oversized.

What If I Believe My Product Isn’t Oversize?

If you believe your product has been incorrectly classified as oversized, you can submit a remeasurement request to Amazon. Amazon will then measure and weigh your product again to determine if it has been correctly classified. If it’s determined that your product is not oversized, Amazon will reimburse any oversized fees.

Final Thoughts

Understanding Amazon's oversized inventory guidelines is crucial for sellers who want to avoid additional fees and shipping charges. By knowing the size tiers, how to determine the product size tier and the fees associated with oversized products, you can make informed decisions about which products to sell on Amazon and which products to avoid (if you prefer not to deal with oversized items).
