Costco Wholesale Structural Packaging Specifications

The Costco package testing requirements aim to focus on lowering costs and ensuring that products arrive safely. Thus, packages must be engineered to maintain its structural integrity throughout Costco’s entire supply chain.

Costco will continually persist in conducting random performance compliance audits to ensure packages meet their specifications. No new items will be brought into the system unless it is compliant with Costco’s packaging requirements.

As an ISTA and ISO 17025 certified lab, we realize the importance of Costco’s new structural specifications. Meeting those requirements can be difficult. We understand the challenges and guide companies through the process. Keystone Package Testing provides the peace of mind that all of your needs will be met. When packages do not meet the requirements, we assist with finding solutions.

Costco Structural Packaging Specifications

According to Costco shipping requirements, packaging must be engineered to comply with ISTA pre-shipment tests Procedure 1A and Procedure 3E. Packages must also be engineered to withstand the following conditions:

  • Long haul transit dynamic load factors
  • Forklift, pallet jack handling and mechanical layer clamping
  • 80-90% high humidity environmental conditions
  • A minimum of four weeks storage time under load weight

Pallet load configurations must be met specifically tailored to the Costco package requirements. This includes pallet loads for corrugated boxes, bagged products and shipping containers not exceeding 2500 lbs. The pallet load must also maximize the packaging area without gaps between units.

ISTA Procedure 1A and Procedure 3E Testing Information

ISTA Test Procedure 1A covers testing of individually packaged products weighing 150 lb or less when prepared for shipment. The test procedure consists of both vibration and shock, with the vibration test being fixed displacement. The shock test consists of drop, incline impact and horizontal impact.

The test sequence protocol for ISTA-1A includes the following:

Test Block 1: ISTA 1A Atmospheric Preconditioning.

Test Block 2: ISTA 1A Vibration – Fixed Displacement.

Test Block 3: ISTA 1A Shock – Drop, Inclined Impact and Horizontal Impact. With ISTA 1A test drop height may vary per package.

ISTA 3E can be used to evaluate the protective performance of packaged-products related to vibrations, shocks and other stresses normally encountered during handling and transportation. It can also be used to evaluate load stability.

ISTA 3E covers the testing of unitized loads, made up of either single or multiple products or packages of the same products. The shipper shall determine the following prior to testing:

  • What constitutes damage to the product, and
  • What damage tolerance level is allowable, if any, and
  • The correct methodology to determine product condition at the conclusion of the test, and
  • The acceptable package condition at the conclusion of the test.

Significance of Costco Structural Packaging Specifications?

Costco merchandises inventory on 48” x 40” pallets. These pallet loads are moved by forklifts or pallet jacks. Packaging must be display-ready, with no handling required. If a package is non-compliant, the item is at risk of deletion, or, may be subjected to a 2% charge back.

Costco package test goal is to drive out costs by eliminating extra packaging, handling, and corrugated waste. It is a requirement of doing business with Costco that the trays required to transport goods are useful in every way. These trays include functional boxes for members to carry out their purchases.
