Question 1

Can a QR code replace information required on the label?

Accepted Answer

Only where a rule specifically allows it. Mandatory US label elements such as the statement of identity, net quantity, ingredient list, allergen declaration and Nutrition Facts panel must be on the package. A QR code is an addition for traceability, provenance, recipes or extended information, not a way to move required text off the pack.

Question 2

What is the text-message disclosure for bioengineered food?

Accepted Answer

The USDA National Bioengineered Food Disclosure Standard permits an electronic or digital disclosure, and where that route is used the label must carry accompanying instructions and a telephone number for a text-message option, so a shopper without a smartphone can still get the information. The wording of the on-pack instruction is prescribed, so follow the standard rather than paraphrasing it.

Question 3

What makes a QR code fail in practice?

Accepted Answer

Too little quiet zone around it, insufficient contrast, printing it too small for the substrate, placing it on a curved or crimped area, or inverting the colours. Test the printed pack under retail lighting with several phones, not the artwork on screen. A code that only scans off a monitor is a code that fails in the aisle.

Question 4

Should the destination URL be permanent?

Accepted Answer

Yes, and point it at a URL you control that can be redirected later. Packaging outlives websites: printed stock stays in the supply chain for months or years, and a dead link on a pack cannot be patched. A stable short URL under your own domain, redirected server-side, is the safe pattern.
