Additional Package Fees:

  • 尺寸(DIM)重量率适用于大而轻的包装. 如果你的包裹大于1立方英尺(1728立方英寸):

    1. 长×宽×高乘以166得到DIM重量(磅).
    2. 如果DIM重量大于实际包装重量，您需要支付DIM重量价格.

    例子:你有一个16英寸x 12英寸x 10英寸的包裹，重5磅.

    1. 长×宽×高相乘得到1920立方英寸的体积. That’s larger than 1 cubic foot (1,728 cubic inches), so you must divide by 166 to find its DIM weight: 1,920 divided by 166 equals 11.56, which rounds up to 12 lbs.
    2. 12磅的DIM重量大于5磅的实际包装重量. 你必须付邮资，就好像包裹实际重12磅一样.

    • 如果您遗漏或提供不准确的尺寸和/或未支付DIM重量率(当适用时), you’ll pay a dimension-noncompliance fee of $1.50.

  • 非标准费用:您将为发送非标准尺寸支付额外费用:
    1. 通过USPS地面优势进行地面运输，如果您的包裹尺寸:
      • Between 22 and 30 inches long: add $4.00
      • More than 30 inches long: add $8.40
      • More than 2 cubic feet (3,456 cubic inches): add $18.00
    2. 特快专递(特快专递或特快专递), you’ll pay more if your package measures:
      • Between 22 and 30 inches long: add $4.00
      • More than 30 inches long: add $18.00
      • More than 2 cubic feet (3,456 cubic inches): add $30.00
