Walmart Package Testing: Packaging Requirements for National Brands

Understanding the Walmart Supply Chain is crucial for suppliers aiming to meet the company’s strict packaging standards. More specifically, transit testing is a mandatory step for all suppliers. Transit testing ensures that the packaging can withstand the rigors of shipping and handling.

eCommerce shipments at Walmart have specific guidelines that suppliers must adhere to. These include specific packaging dimensions and warehouse pack quantities. With the rise of online shopping, ensuring that eCommerce shipments meet high-quality standards is more important than ever.

The Walmart package testing guidelines are designed to streamline the order fulfillment process, making it more efficient and customer-friendly.

The Importance of Transit Testing

Transit testing is a series of tests performed on packaged products to simulate the conditions they will encounter during shipping and handling. These tests evaluate how packaging protects products from damage due to drops, vibrations, temperature changes, and other environmental factors.

The goal is to ensure products reach the customer in the same condition they left the manufacturer or supplier.

Walmart’s Specific Requirements for Transit Testing

Moreover, Packaging Standards at Walmart are designed to ensure that products can withstand the rigors of shipping and handling. These standards are part of Walmart’s broader testing protocols and are crucial for supplier compliance.

Additionally, Walmart strongly emphasizes Packaging Quality Control to reduce damaged returns and improve customer satisfaction. By adhering to Walmart’s specific transit testing demands, suppliers can ensure compliance and contribute to a better customer experience.

ISTA 3 Series Tests

Walmart uses ISTA Series 3 tests. ISTA stands for the International Safe Transit Association. These package integrity tests are advanced tests designed to challenge a package and product’s ability to withstand transport hazards.

Suppliers must submit a production sample of the item to any ISTA-certified lab for testing. Any changes to the packaging or product after this will require a retest.

Procedure 3A

A general simulation test for individually packaged products shipped through a parcel delivery system. It includes an optional test combining random vibration under low pressure, simulating high altitude.

Procedure 3B

A general simulation test for packaged products shipped through a motor carrier (truck) delivery system, often mixed in the same load. This type of shipment is called Less-Than-Truckload (LTL).

Procedure 3E

A general simulation test for unitized loads of similar retail or institutional packaged products shipped from a manufacturing location to a distribution center. The unitized loads are shipped through a motor carrier (truck) delivery system.

Oftentimes, unitized loads are of similar retail packaged products. The loads are intended for one destination. This type of shipment is called Full Truckload (FTL).

How Walmart’s Package Integrity Testing Needs Differ

Walmart’s testing protocols go above and beyond standard industry practices by incorporating unique features like Atmospheric Conditioning and specialized tests for certain products like large-screen TVs.

These additional layers of testing are designed to uphold the integrity of Walmart’s Private and Exclusive Brands, ensuring that customers receive products in top-notch condition. 

Atmospheric Conditioning

Unlike standard ISTA tests, Walmart requires an additional step of Atmospheric Conditioning for its Private and Exclusive Brand items. This simulates real-world environmental conditions like temperature and humidity, making the testing process more rigorous.

Clamp Testing

Another added layer is the ISTA SAMS CLUB 6A Clamp Test, specifically required for Walmart’s Private and Exclusive Brand items within General Merchandise. This is not a standard requirement in typical ISTA tests.

Special Protocols

Walmart has a specific testing protocol for specific items such as TVs. This means products go through an additional layer of scrutiny. The goal is to ensure they meet Walmart’s quality standards.

This ensures that high-value items are durable and reliable, minimizing the risk of returns or customer dissatisfaction.

Retest Policy

Unlike standard industry practices, Walmart may request a retest for items with return rates above the department average. Any changes to the packaging or product after initial testing will require a retest. This ensures ongoing compliance and quality.
