When sourcing at scale, authenticity is paramount. Ensure the product features original Nestlé branding with clear, high-resolution printing. Check for batch numbers, production dates, and expiration dates embossed or printed clearly on the outer carton and individual foil wraps. The cubes should have a consistent texture and aroma; any signs of moisture, discoloration, or a rancid smell indicate poor storage or counterfeit production. Requesting a Certificate of Analysis (COA) from the supplier is a standard industry practice to verify ingredient composition.
