Choosing the right packaging test is one of the most important decisions in any validation process. It affects how well your product survives distribution, how quickly you can launch, and whether you meet the expectations of retailers and carriers. With multiple ISTA and ASTM options available, it can be hard to know where to begin, especially when you are working against deadlines.
This guide breaks down the basics so you can make a clear, confident decision about which test fits your packaging.
Why the Right Test Matters
Even strong packaging designs can fail if the wrong protocol is selected. Making an informed choice helps you avoid unnecessary redesigns, protect your product in transit, reduce freight claims, and keep your packaging program efficient. It also sets you up for smoother conversations with retailers who often require specific test methods.
If you are unsure which hazards your product will face during distribution, our team can help walk through your supply chain and match it to the right approach.
When ISTA Tests Are the Best Fit
ISTA protocols are built to simulate real transportation conditions in a structured and repeatable way. These tests are a good fit when:
• A retailer such as Amazon, Walmart or Target specifies the method. (Link to Walmart’s distribution requirements)
• You want a quick and standardized simulation of parcel or LTL distribution
• Your product is heading into e commerce
• You need a full distribution sequence without customization
If your supply chain is well understood and you want a clear test path, ISTA is often the most efficient option. Learn more about ISTA.
When ASTM Tests Are the Best Fit
ASTM methods give you more flexibility and more control over the details. They are especially useful when:
• You want to isolate a single failure mode
• You need material level insights
• You are troubleshooting or refining a packaging design
• You want to create a custom sequence or combine specific test elements
Many teams use ASTM early in development, then shift to ISTA for final validation once they are ready for full distribution simulation. Learn more about ASTM.
A Quick Guide to Help You Decide
Choose ISTA if you need retail compliance, a complete distribution simulation, or a fast path to validation.
Choose ASTM if you need flexibility, detailed performance data, or a way to study materials and components more closely.
If you are still unsure, feel free to reach out. A short conversation is usually all it takes to point you in the right direction.
What to Prepare Before Testing
To make test planning smoother, it helps to gather a few basic details up front. This includes:
• Product weight and dimensions
• Packaging configuration
• Pallet pattern if applicable
• Retailer or carrier requirements
• Transportation mode such as parcel, LTL or air
• Conditioning needs like temperature or humidity
• Any fragile or critical components
Having this information ready helps avoid delays and ensures the test sequence is chosen correctly.
Where gh Testing Performs These Tests
We offer packaging and product testing through two lab locations so you can choose the one that fits your timeline and logistics needs.
Central Lab in Ohio
Our main facility with the widest range of ISTA and ASTM capabilities.
Southwest Lab in Arizona
Ideal for West Coast and Southwest companies who want to shorten freight time and reduce cost.
Not all tests are available in both locations, so reach out and we can guide you to the right facility.
Together our two locations support packaging engineers, manufacturers, and product teams across consumer goods, industrial products, medical devices, and display packaging.
Need help choosing the right test?
Most packaging test plans can be clarified in a short conversation. We help teams avoid unnecessary testing, reduce project risk, and move faster from concept to completion.
