Quick answer: A private-label nootropic pouch SKU normally needs a unique product identifier for each distinct trade item. Flavor, strength, count or pack configuration changes can require a different GTIN. Retail cans and logistics cases may use different barcode carriers and identifiers, so allocate numbers before final artwork.
What buyers need to understand
The brand owner should license identifiers through the appropriate GS1 member organization and control the product master data. Do not copy a supplier or marketplace barcode.
How to specify and verify it
Verify quiet zones, size, contrast, print quality, curvature and scanner performance on the actual can. Link the correct GTIN to product name, count, net quantity, dimensions, case hierarchy and market data.

Frequently asked questions
Can one number or sample approve the product?
No. Quality decisions combine specifications, methods, trend data, sensory performance, packaging and market requirements.
Should the supplier define every limit?
The manufacturer can propose capable ranges, but the brand owner should review and formally approve the commercial and regulatory specification.
How should buyers compare suppliers?
Give each supplier the same written brief, test requirements, packaging scope and destination so comparisons remain meaningful.
