UPS Ground Shipping from Hawaii and Package Dimension Requirements

Shopify Discussion

Topic summary

Confusion about UPS Ground availability from Hawaii and dimension requirements for large packages. A Honolulu shipper read that UPS does not offer UPS Ground from Hawaii to the mainland and that certain package sizes require full dimensions (L × W × H), even for polymailers.

Despite this, Shopify allowed purchase of a UPS Ground label for a 30 × 30 inch polymailer without entering a height. The poster asks whether this is a consistent allowance or a rare exception.

Requested insights: real-world experience shipping large packages from Hawaii, whether UPS truly requires all three dimensions for larger items/polymailers, and if UPS Ground from Hawaii to the mainland is actually possible in practice.

Status: open and unresolved; no confirmed guidance or outcomes yet.

We’re shipping from Honolulu and ran into some confusion with UPS Ground and large package dimensions.

I read that UPS doesn’t offer UPS Ground from Hawaii to the mainland. I also heard that for certain package sizes, UPS requires all three dimensions (L x W x H) to be specified, even for polymailers. However, Shopify allowed me to purchase a UPS Ground label for a 30 x 30" polymailer without entering a height. And this is from Hawaii to the mainland. I’m curious if this will work consistently or if it’s a rare exception?

Does anyone here have experience with large package requirements from Hawaii? Any insight on whether UPS Ground from Hawaii to the mainland is actually possible would be really helpful!
