CarrierBot

CarrierBot provides shipping rates within Japan. To receive a rate, your request must meet the following criteria:

  1. The Shipping Address must include a valid province code (JP-01 to JP-47)
  2. All SKUs must follow the required format, e.g. APA-C301

Example of an SKU:

The product here is called Australia Pale Ale, and the prefix “APA” has been decided

  • APA-C301 (single can)
  • APA-C306 (can 6-pack)
  • APA-KL10 (10 litre keg)

{PREFIX}-{SUFFIX}

There must be a prefix, followed by a -, followed by a suffix

CarrierBot finds the -, ignores the prefix, and bases the rates off the suffix.

Suffix Rules

For Kegs

  • Optional K at the beginning
  • followed by one uppercase letter L, U or P
  • followed by exactly 2 digits

Valid Examples:

  • KL10
  • KU20
  • KP15
  • L10
  • U20
  • P15

For non-Kegs

  • one uppercase letter B, C or M
    • represents Bottle, Can, or Merch
  • followed by exactly 3 digits

Valid Examples:

  • C301
  • B506
  • M080

SKUS starting with M have different behaviour to other SKUs.

Whether you have x1 M or x99, ther will only be 1 charge for it. The idea is that it might be a shirt, and 1 shirt, or 20 shirts can all fit in 1 box.

Item price is used in two ways but does not change the per-unit shipping rate.

The total value of all items on an order (including merch) is added up. If it meets or exceeds a regional threshold, the entire order ships for free.

For example, if the threshold for Kanto is ¥7,000, then a ¥7,000 T-shirt order to a Kanto address ships free. A ¥5,000 order to the same region would still be charged shipping.

A handling fee is applied based on the total order value (items + shipping):

Order ValueHandling Fee
< ¥10,000¥324
¥10,000–¥30,000¥432
¥30,000–¥100,000¥648
≥ ¥1,000,000¥4,320
  • The shipping rate itself: MS/ML shipping is a flat fee per size, regardless of item price. A ¥100 sticker ships for the same amount as a ¥5,000 shirt (if unbundled).
  • Discounts or subsidies: Merch is not eligible for either.

Item price only matters for threshold calculations, not for the per-unit shipping rate.
