Understanding Product Packaging Requirements in the US

Overview of US Product Packaging Requirements

Product packaging in the United States is governed by several federal agencies and laws that protect consumers and ensure fair business practices. The primary goal of these requirements is to provide accurate information about what's inside a package, how to use the product safely, and what the consumer is actually purchasing. Unlike many other countries with centralized packaging rules, the US has a decentralized system where different agencies oversee different types of products.

The Food and Drug Administration (FDA) manages packaging for food and drugs. The Federal Trade Commission (FTC) oversees packaging claims and labeling practices across most consumer products. The Consumer Product Safety Commission (CPSC) sets requirements for product safety information on packaging. The Environmental Protection Agency (EPA) establishes rules for certain product categories like pesticides and chemicals. Understanding which agency governs your product category is the first step toward compliance.

Packaging requirements exist at both the federal and state levels. Federal rules set the minimum standards that all manufacturers must follow across the country. States can impose additional requirements beyond federal minimums, which means a product might need different packaging for different states. For example, California has stricter labeling requirements for certain chemicals than most other states. This layered approach means manufacturers often must design packaging that meets the most stringent requirements to distribute nationwide.

The cost of compliance varies significantly based on product type, but it's a mandatory business expense. Manufacturers cannot choose to ignore packaging requirements to save money. Non-compliance can result in fines ranging from hundreds to millions of dollars, product recalls, and legal liability if someone is harmed because packaging information was missing or incorrect.

Practical Takeaway: Before designing product packaging, identify which federal agencies regulate your product category. This determines which specific requirements you must follow and which agency will inspect your compliance.

Principal Display Panel and Information Panel Requirements

The Principal Display Panel (PDP) is the area of packaging most likely to be seen by consumers when the product is displayed for sale. For most products, this is typically the front of the package. The Information Panel is the back or side of the package where detailed product information appears. These two areas have different legal requirements, and understanding the distinction is critical for compliance.

On the Principal Display Panel, manufacturers must include the product identity (what the product is called) and the net quantity statement (how much product is inside). The net quantity must be stated in both metric and US customary units on most products. For example, a cereal box must state "16 oz (453g)" or similar. The placement and size of this information is regulated. The net quantity statement must be in the lower 30 percent of the PDP in most cases, and the type size must be proportional to the PDP size—typically no smaller than 1/8 inch height for smaller packages.

The Information Panel contains more detailed information including the ingredient list, allergen information, directions for use, warnings, manufacturer information, and other details specific to the product type. For food products, the Nutrition Facts panel must appear on the Information Panel. The placement of the Information Panel must follow specific rules—it generally should be on the back or right side of the package when viewed by consumers. If the package is too small, some information can appear on a label attached to the package or even on an insert, though this is less common.

Both panels must use readable fonts that contrast clearly with the background. For the PDP, the required information must be easy to read without needing to rotate the package. The Information Panel can use smaller text than the PDP, but it still must be legible without magnification for most people. Type must be in a sans-serif font for many product categories, though this varies by product type.

Different product categories have slightly different rules for what must appear on each panel. Food products have different requirements than cosmetics, which have different requirements than household chemicals. However, the basic structure of having a PDP and Information Panel with distinct information requirements applies across most product categories.

Practical Takeaway: Design your packaging with clear separation between the Principal Display Panel (front) showing product name and net quantity, and the Information Panel (back/side) showing detailed requirements like ingredients, directions, and warnings. Follow your product category's specific rules for text size and placement.

Net Quantity and Measurement Declarations

The net quantity statement tells consumers how much product they are purchasing. This is distinct from the gross weight, which includes packaging material. Manufacturers must be accurate about net quantity because consumers rely on this information to make purchasing decisions and compare prices between brands. The FTC and state attorney general offices actively investigate complaints about net quantity misstatements.

Net quantity must be stated using appropriate measurement units based on the product type. For solid products like cereal, the unit is typically weight (ounces or grams). For liquids like juice or milk, the unit is volume (fluid ounces or milliliters). For other products like count items (sheets of paper towels, number of items), the quantity is stated as a count. Some products use multiple units—for example, a package of deli meat might state both weight and count if applicable.

The dual unit requirement means most packages must show both US customary units and metric units. A package must state "16 oz (453g)" rather than just ounces or just grams. The order of these units can vary, but both must be clearly visible. The metric unit can be parenthetical (smaller), but both must be equally prominent and readable. This dual-unit requirement applies to virtually all consumer products sold in the US.

The placement of the net quantity statement follows specific rules. On rectangular packages, it must appear in the lower 30 percent of the PDP, and it must be positioned at least one inch from the bottom edge and from the corners. The type size must be proportional to the PDP—larger packages require larger type. For a package with a PDP of 20 square inches, the net quantity type must be at least 1/4 inch in height. For smaller packages, the proportions adjust accordingly.

Manufacturers must ensure that the net quantity statement is not obscured by design elements, shadows, or packaging flaps. It cannot be hidden behind a label or placed where consumers would need to rotate the package to see it. Some products, like those sold in bulk at warehouse stores, may have different requirements if the packaging is designed for stacking or industrial display.

The accuracy of net quantity statements is regularly monitored through package testing. Regulatory agencies or their contracted laboratories purchase products and measure the actual contents to verify that packages contain at least the stated quantity. Products that consistently contain less than stated amount face regulatory action. This means manufacturers must actually account for natural variation and ensure consistent filling.

Practical Takeaway: Display net quantity on the Principal Display Panel in the lower 30 percent, using both US customary and metric units in appropriately sized type. Verify through testing that your packages consistently contain at least the stated amount.

Ingredient Disclosure and Allergen Labeling

All food products sold in the US must list ingredients on the Information Panel in descending order by weight. This requirement exists so consumers can make informed choices about what they consume. The list must be titled "Ingredients" and each ingredient must use its common name, not chemical names that consumers wouldn't recognize. For example, "ascorbic acid" can also be called "vitamin C" so consumers understand what it is.

Ingredients must be listed in order of predominance by weight at the time of manufacture. The ingredient that weighs the most appears first, the second-most appears second, and so on. This helps consumers quickly understand what makes up the bulk of the product. For example, in a bread product, flour typically appears first because it comprises the largest portion by weight. This ordering requirement applies across all food products regardless of package size.

The Food Allergen Labeling and Consumer Protection Act (FALCPA) requires that food products clearly declare eight major allergens: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans. These allergens must be clearly stated on the Information Panel. Many manufacturers use a separate "Contains:" statement in plain language—for example, "Contains: Milk, Wheat" rather than burying allergen information in the ingredient list. This practice, while not legally required, has become standard because it helps consumers with allergies quickly identify whether they can safely consume the product.

When an ingredient itself contains an allergen, that allergen must be declared. For example, if a product contains "natural flavor" that is derived from shellfish, the product must declare the shellfish allergen. Some manufacturers use advisory labels like "May contain
