QR codes on food and cosmetic labels: what a code cannot replace

What has to stay printed?

The FDA Food Labeling Guide summarizes the required statements for packaged food sold in the United States, including a statement of identity on the principal display panel, net quantity of contents, an ingredient list in descending order of predominance, declaration of the major food allergens, the name and place of business of the manufacturer, packer or distributor, and Nutrition Facts unless the product is exempt.

None of that moves behind a scan. The reason is simple: the rules exist so a shopper holding the package can read the information, and a scan requires a working phone, a signal and a willing reader.

Cosmetics have their own required elements, and other categories have their own regulators. Confirm your own category before you design, because the space your required text needs decides how much room is left for anything else. The existing guide to what to put on a product label sets out the requirements in detail.

Where does a code earn its place on a package?

Once the required text is placed, a code is genuinely useful for information that is long, changes often, or is only relevant after purchase.

• Sourcing and production detail that will not fit, such as farm, roast date or batch story.
• Recipes and serving suggestions for food.
• How to use, how to refill and how to recycle.
• Full ingredient explanations in plain language, alongside the required list.
• Care instructions for cosmetics and household goods.
• Reordering, which is the highest value link on most consumer packaging.

A code linking to a homepage is wasted. Link to the specific thing the person holding the package needs next.

What about claims made on the linked page?

This is the part that catches small brands. Content behind a code is still marketing for the product, and claims made there are subject to the same advertising and labeling rules as claims on the package.

If the linked page says organic, natural, sustainable, clinically proven or hypoallergenic, those words carry the same obligations they would carry printed on the box. A code does not create a space where claims are informal. Keep the linked page as carefully reviewed as the label artwork, and keep a dated copy of what it said when each batch shipped.

The same applies to nutrition and health claims on food. Making a nutrient content claim can change which exemptions apply to the product, so it is not a decision to make casually on a web page.

How do you find room for the code?

Small packages are tight before you add anything. Three practical moves usually free up the space.

First, move optional content off the label and behind the code, which is what the code is for. Second, use a two label layout: a front label for brand, product name and net quantity, and a back label for the ingredient list, allergens, address, barcode and the QR code. Third, check minimum type heights before you shrink anything, since some required text has a stated minimum height and cannot be reduced to make room.

Place the code away from seams, curves and the retail barcode. Two codes side by side confuse scanners and shoppers alike, and a code that wraps around a jar loses the flat area it needs.

How big should the code be on a package?

Big enough to scan while the product is in the hand, which for most packaging means a code at least 20 mm across with a clear margin of at least four modules on every side.

Two details matter more on packaging than on flat print. Surfaces are often glossy, curved or reflective, and packaging gets handled, so choose a higher error correction level than you would use on a card. The guide to error correction levels explains the trade off, and the existing guide to QR codes on packaging covers surface, size and lifespan in depth.

Will the link still work in two years?

Packaging outlives campaigns. A product printed today may sit in a cupboard for a year and be scanned after that.

Use a short path on your own domain that redirects, so you can change the destination without reprinting. Avoid third party shorteners you do not control, because the FTC's guidance to consumers is to check that a QR destination looks like a URL they recognize, and an unfamiliar domain gives them nothing to recognize. Keep a record of which batch points where, so an old code can be repointed rather than left broken.

What is the packaging code checklist?

• Place every required statement on the label first, then look for space.
• Never move required information behind a scan.
• Link to one useful thing, usually reorder, care or provenance.
• Review claims on the linked page as carefully as claims on the label.
• Keep the code at least 20 mm with a four module margin, away from seams and the barcode.
• Use a higher error correction level for handled packaging.
• Point the code at a short path on your own domain that you can redirect.
