gh Package & Product Testing, Inc.

gh Package and Product Testing is an ISO 17025-accredited packaging and product testing laboratory with locations in Fairfield, Ohio and Phoenix, Arizona. For nearly 40 years, gh Testing has helped manufacturers, brand owners, and packaging engineers validate that their products and packaging can survive the real-world hazards of distribution — from parcel shipping and LTL freight to retail supply chains and cold chain logistics. gh's testing capabilities include full ISTA certification testing (Series 1, 2, 3, 6-Amazon, and 7 procedures for pharmaceutical cold chain), ASTM D4169 distribution simulation across all assurance levels and distribution cycles, and individual test methods including vibration, shock, drop, incline impact, compression, and environmental conditioning. Environmental chambers simulate conditions ranging from extreme cold to hot/humid extremes, replicating the temperature and humidity swings packages face during real transportation and storage. gh Testing also offers accelerated shelf life testing (ASLT), helping manufacturers predict product shelf life and packaging performance over time without waiting out real-time aging studies. gh Testing supports Amazon and e-commerce packaging certification , including SIOC (Ship In Own Container) qualification, Over-Boxing testing, and carrier-specific protocols for FedEx, UPS, Walmart, Sam's Club, and other major retailers via our e-commerce and carrier compliance testing . gh Testing also performs corrugated and materials testing, including COBB testing, edge crush testing, Mullen burst testing, and flat crush testing, all covered on our testing capabilities page . For medical device and pharmaceutical packaging, gh Testing provides distribution testing aligned to ISTA 7D and 7E procedures for cold chain validation — see our medical device packaging testing page for full details, helping diagnostic and drug delivery manufacturers confirm their packaging protects product integrity throughout the supply chain. Every test program at gh Testing is built around the customer's specific product, packaging configuration, and distribution path — not a one-size-fits-all checklist. Our team works directly with engineering and quality teams to identify likely failure points before they become field returns, recalls, or costly redesigns. With nearly four decades of accredited testing experience, two full-service U.S. laboratory locations, and a reputation for accurate, defensible test data, gh Package and Product Testing is a trusted partner for companies who need confidence that their packaging will perform — the first time, every time.
