The 8 Amazon-Approved
TIC Providers — which one should you use?

Amazon names eight third-party Testing, Inspection & Certification providers as approved for supplement compliance: NSF, USP, Certified Laboratories, Eurofins, SGS, UL Solutions, Intertek, and Mérieux NutriSciences. Strengths, scopes, turnaround times, and per-SKU pricing vary by an order of magnitude. The wrong choice can add weeks to a 90-day window.

We put together a one-page reference: each provider, their gold-standard scope, typical turnaround, and the category fit Merit routes them for. Drop your email and we’ll send the PDF.
