商品尺寸分段

配送费用取决于商品包装后的重量和尺寸（商品尺寸分段）。

重要： 对于多渠道配送订单，请参阅多渠道配送订单的配送费用。

标准尺寸商品与大件商品

标准尺寸商品是指完全包装后的重量不超过 20 磅并且尺寸不超过以下标准的商品：

• 最长边 18 英寸

• 次长边 14 英寸

• 最短边 8 英寸

超过上述尺寸的商品属于大件商品。

重要： 如果商品成套销售，那么我们会计算整套商品包装在一起之后的总体重量和尺寸。

确定商品的尺寸分段

要确定商品的正确分段，请在下表中找到测量值不超出商品的重量或尺寸的行。

对于重量不超过 1 磅的标准尺寸商品以及特殊大件商品，亚马逊采用单件重量。对于所有其他商品，亚马逊将采用单件商品重量与体积重量中的较大者。体积重量等于商品体积（长 x 宽 x 高）除以 139。大件商品的的体积重量假定最小宽度和高度为 2 英寸。

要计算长度加围度，请执行以下操作：

1. 测量包装后的商品的长度、高度和宽度。

2. 将最短边和次长边相加，然后乘以 2 得出围度。

3. 将最长边和围度相加。

重要： 亚马逊可能会使用代表性样本验证商品的重量和尺寸。如果亚马逊的信息与卖家的信息存在差异，将使用亚马逊关于商品重量和尺寸的信息来计算费用。亚马逊可能会不时更改关于商品重量和尺寸的信息，以反映更新后的测量结果。我们将根据商品的重量和尺寸计算费用，并在计算时使用亚马逊关于商品重量和尺寸的信息。

*特殊大件

特殊大件分段适用于由于其尺寸、重量、特殊处理要求或其他限制，必须使用特殊配送方式配送的商品。如果满足以下任意条件，则商品将被划分为特殊大件并据此收费：

• 商品尺寸的最长边大于 108 英寸

• 单件重量或体积重量大于 150 磅

• 长度 + 围度总和超过 165 英寸

• 亚马逊规定此类商品需要特殊处理，以便确保良好的买家体验

更改商品的重量或尺寸

如果您是某个 ASIN 的唯一卖家，且需要更改商品的重量或尺寸，请联系卖家支持并说明您需要更新测量值。如果此商品目前还有库存，您可能需要先将其销售完，系统才会显示新的重量和尺寸。

注意： 亚马逊存储的是 ASIN 级别的重量和尺寸。我们无法针对测量值找到具体的商品。如果多个卖家销售相同的 ASIN，则重量和尺寸信息表现出的可能不是您的特定商品。

Product size tiers

Fulfillment fees are based on the weight and dimensions of the packaged item (the product size tier).

Important: For multi-channel fulfillment orders, see Fulfillment fees for multi-channel fulfillment orders.

Standard-size versus oversize

A standard-size item is one that, when fully packaged, weighs 20 lb or less and does not exceed:

• 18 inches on its longest side

• 14 inches on its median side

• 8 inches on its shortest side

Any item exceeding these dimensions is considered oversize.

Important: If a product is sold as a set, the weight and dimensions are the combined total of all of the items in the set packaged together.

Determine the product size tier for your item

To determine the correct tier for your item, find the row in the table below with measurements that do not exceed the weight or the dimensions of your item.

For standard-size products that weigh 1 lb or less, and for special oversize products, use the unit weight. For all other products, use the larger of either the single unit weight or the dimensional weight. The dimensional weight is equal to 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.

To calculate the length plus girth:

1. Measure the length, height, and width of the packaged unit.

2. Calculate the girth by adding the shortest and median sides and multiplying by 2.

3. Add the longest side and girth.

Maximum weights and dimensions for packaged items
Product size tier	Weight	Longest side	Median side	Shortest side	Length + girth
Small standard-size	12 oz	15 inches	12 inches	0.75 inch	n/a
Large standard-size	20 lb	18 inches	14 inches	8 inches	n/a
Small oversize	70 lb	60 inches	30 inches	n/a	130 inches
Medium oversize	150 lb	108 inches	n/a	n/a	130 inches
Large oversize	150 lb	108 inches	n/a	n/a	165 inches
Special oversize*	Over 150 lb	Over 108 inches	n/a	n/a	Over 165 inches

Important: Amazon may verify the weight and dimensions of a product using representative samples. Amazon's information about a product's weight and dimensions will be used to calculate fees if there is a difference between Amazon's information and a seller's information. Amazon may change its information about a product's weight and dimensions from time to time to reflect updated measurements. Fees based on the weight and dimensions of a product are calculated using Amazon's information about the weight and dimensions of that product at the time the fee is calculated.

*Special oversize

The special oversize tier applies to products that must be delivered using special delivery options due to their size, weight, special handling requirements, or other restrictions. Products are classified and charged as special oversize if any of the following is true:

• Dimensions are greater than 108 inches on the longest side

• Unit weight or dimensional weight is greater than 150 lb

• Length + girth is greater than 165 inches

• Amazon has determined that the product requires special handling to ensure a good customer experience

Change a product's weight or dimensions

When you are the only seller of an ASIN and you need to change your product's weight or dimensions, contact Seller Support and explain that you need to update the measurements. If you currently have inventory for the product, you may need to sell through it before the new weight and dimensions show.

Note: Amazon stores weight and dimensions at the ASIN level. We cannot target a specific unit for measurement. When multiple sellers sell the same ASIN, the weight and dimensions information may not represent your specific units.

常见问答(FQAS)

亚马逊计算仓储费用主要根据产品尺寸和重量。具体来说,根据产品的尺寸计算立方体空间,然后根据重量计费。一般情况下,重量越重,占用空间越大,费用也会越高。

亚马逊按照产品的长、宽、高三个维度来测量体积,并计为立方体。体积会继续上浮到最小尺寸单位,例如0.1立方英尺。然后根据体积计费。体积越大,费用越高。一些超大件商品可能需要额外计费。

重量按照基础重量下限起计算。例如1磅起步。超出部分按磅收费。通常每增加1磅增加固定费用。同时产品本身的重量也会影响其尺寸计费结果,因为占用空间更大。

是的,除尺寸和重量计费外,亚马逊还可能增收其他费用,比如每单费用、包装费用等。这些费用会因产品种类和地区不同而不同。建议商户事先了解清楚各项费用标准,以避免仓储费超支。
