What does Ti Hi mean in shipping?

Ti Hi is a pallet configuration term used in warehousing and retail supply chains. Ti (Tier) is the number of cases or cartons in a single layer on the pallet. Hi (High) is the number of layers stacked on the pallet. Ti × Hi gives total units per pallet. For example, Ti 10 × Hi 5 = 50 cases per pallet.

How do you calculate Ti Hi?

To calculate Ti: divide pallet length by carton length to get columns, divide pallet width by carton width to get rows, multiply columns × rows = Ti. To calculate Hi: divide maximum stack height by carton height = Hi. Total units per pallet = Ti × Hi.

What is a standard Ti Hi for Walmart?

Walmart's Supplier Quality Excellence Program (SQEP) requires vendors to declare Ti Hi on pallet labels. There is no single standard — Ti Hi varies by product. Walmart requires the Ti Hi to match the actual pallet configuration exactly. Mismatches can result in chargebacks.

What pallet size should I use for Ti Hi calculation?

The most common pallet in North America is the 48×40 GMA pallet. Walmart, Target, and most US retailers use 48×40. European supply chains use the 47×31 EUR pallet. Some warehouses use 48×48 square pallets for uniform stacking. Always confirm pallet size with your customer before calculating Ti Hi.

What is the maximum pallet height for shipping?

Standard maximum pallet height is 60 inches (including pallet) for most LTL and retail. Walmart allows up to 60 inches total height. Amazon FBA requires pallets under 72 inches. Floor-loaded containers allow up to 94 inches. Always confirm height restrictions with your customer or carrier before building pallets.

Ti — Tier

Units per layer

How many cartons fit flat on one layer of the pallet.

📐

Hi — High

Number of layers

How many layers stack on top of each other before hitting the height limit.

🧮

Ti × Hi

Total units/pallet

Multiply them together to get total cartons per pallet. e.g. Ti 8 × Hi 5 = 40 units.

Where you'll see Ti Hi: Walmart, Target, and Amazon require vendors to print Ti Hi on pallet labels (GS1-128). A declared Ti 10 × Hi 5 means every pallet has exactly 10 cartons per layer, 5 layers high. If your actual pallet doesn't match — expect a chargeback.

What is Ti Hi? Complete Guide

Ti Hi meaning in shipping and warehousing

Ti stands for Tier — the number of cartons or cases in a single layer on a pallet. Hi stands for High — the number of layers stacked on the pallet. Together, Ti × Hi gives you the total number of units per pallet.

Example: if you can fit 10 cases per layer and stack 5 layers high, the Ti Hi is 10 × 5 and the pallet holds 50 cases.

How to calculate Ti Hi manually

To calculate Ti (units per layer):

Divide pallet length by carton length → columns
Divide pallet width by carton width → rows
Columns × rows = Ti
Try rotated orientation (swap L and W) and use whichever gives more units

To calculate Hi (layers):

Take your maximum pallet height (e.g. 60")
Subtract pallet board height (typically 5.5")
Divide by carton height → Hi

Ti Hi requirements for Walmart, Amazon, and Target

Major retailers require vendors to print the Ti Hi on pallet labels. Mismatches between the declared Ti Hi and the actual pallet configuration result in chargebacks.

Walmart SQEP: Ti Hi must be declared on the GS1-128 pallet label. Maximum height 60" including pallet.
Amazon FBA: Maximum pallet height 72" for non-stackable, 48" for stackable. Ti Hi declared in Seller Central.
Target: Follows GS1 standards. Ti Hi printed on licence plate label.

Standard pallet sizes for Ti Hi calculation

Pallet Type	Size (L×W)	Used By
GMA Standard	48×40"	Walmart, Target, most US retail
Square	48×48"	Industrial, drums, heavy goods
EUR/EPAL	47×31"	European supply chains
