A buyer's guide to SGS-audited GMP in label printing

Most CPG brands don't think much about how their label vendor runs quality control — until a defective batch shows up at the dock or a regulator flags an inspection legend. That's when the gap between "we say we're careful" and "we have a system that proves it" becomes a real cost.

What GMP actually means

Good Manufacturing Practices (GMP) is a set of standards covering everything from raw-material handling to finished-good inspection. In label printing, that translates to documented procedures for:

• Substrate and ink storage with lot tracking
• Press setup verification before each run
• In-process quality checks at defined frequencies
• Finished-goods inspection and release
• Non-conformance handling and corrective action

Why third-party auditing matters

You can claim GMP. SGS auditing means an outside firm — not your label vendor — has reviewed your procedures, watched your team execute them, and signed off. The standard itself isn't the differentiator. Independent verification is.

What to ask your current vendor

1. Are you audited to a published quality standard? By whom?
2. How often is the audit performed?
3. What does your QMS catch before it reaches my dock?
4. Can you walk me through a non-conformance and how it was resolved?

If the answers are vague, the system probably is too. Quality is a system, not an apology — and it's measurable.
