Polybag Suffocation Warning Requirements: Retailer Rules, State Laws & Label Specs

What Is a Polybag Suffocation Warning?

A polybag suffocation warning is a printed or labeled notice on plastic bags alerting consumers—especially parents and caregivers—that the bag poses a suffocation hazard to infants and young children. These warnings are legally required in several U.S. states and mandated by major retailers like Amazon, Walmart, and Target for any product shipped in a poly bag.

The standard warning text reads: “To avoid danger of suffocation, keep this plastic bag away from babies and children. Do not use this bag in cribs, beds, carriages, or playpens. This bag is not a toy.” Some jurisdictions and retailers require additional language about the bag blocking the nose and mouth and preventing breathing.

Whether you sell on Amazon FBA, ship to Walmart distribution centers, or fulfill Target.com orders, understanding the exact requirements for suffocation warning labels—including text, font size, placement, and bag thickness thresholds—is critical to avoiding chargebacks, shipment rejections, and legal liability.

Why Are Suffocation Warnings Required?

Plastic bags are one of the leading causes of suffocation-related deaths in children under three years old. The U.S. Consumer Product Safety Commission (CPSC) has issued guidelines recommending that all plastic bags thin enough to conform to a child’s face carry a suffocation warning. While there is no single federal law mandating suffocation warnings on all plastic bags, several states have enacted their own legislation, and major retailers enforce strict packaging standards that go beyond state minimums.

For brands and suppliers, the practical reality is simple: if you ship products in polybags to any major U.S. retailer or sell through Amazon FBA, you must include a suffocation warning that meets the retailer’s specific requirements. Non-compliance results in chargebacks, re-work fees, and potential shipment refusal.

Federal vs. State Requirements

There is no federal statute that specifically requires suffocation warnings on plastic bags. The CPSC provides voluntary guidelines that form the basis of most state laws and retailer standards. However, several states have made these warnings mandatory through legislation, and selling into those states without proper warnings can result in fines and legal liability.

Because retailers distribute to all 50 states, most require suppliers to comply with the strictest applicable standard—effectively making state-level requirements the de facto national standard for any brand selling through retail channels.

Standard Suffocation Warning Text

The CPSC-recommended warning text has become the industry standard. Most retailers and state laws accept variations of this text, but the core message must convey the suffocation hazard and keep-away instructions.

Short-Form vs. Long-Form Warnings

Some suppliers use a shorter version that omits the “block nose and mouth” sentence. While accepted by some retailers, the long-form version is recommended because it satisfies the broadest set of requirements. Amazon, Walmart, and Target all accept the full CPSC-recommended text.

Multilingual Warnings

Walmart specifies that a bilingual warning is only required if other text on the bag is bilingual. For products sold in Canada, French and English warnings are typically required. If you sell cross-border or into markets with multilingual requirements, include warnings in all applicable languages.

Font Size Requirements by Bag Dimensions

The minimum font size for suffocation warnings is determined by the bag’s dimensions—specifically the sum of the bag’s length and width when laid flat. Larger bags require larger type to ensure the warning is visible and readable. While the general brackets are similar, each retailer defines slightly different breakpoints.

How to Measure Your Bag

Lay the bag flat and measure the length (top to bottom) and width (side to side). Add these two measurements together. For example, a 12” × 18” bag has a combined dimension of 30 inches, requiring at least 14-point font for the warning text. Note that Amazon measures the opening width when flat, while Walmart and Target measure the overall bag dimensions.

Bag Thickness Requirements

The minimum polybag thickness and the threshold at which a suffocation warning becomes required vary by retailer. Understanding these differences is important because a bag that is compliant for one retailer may need additional labeling for another.

Amazon’s 5-Inch Rule

Amazon FBA requires suffocation warnings on any polybag with an opening of 5 inches or more when measured flat. This is one of the most specific thresholds among major retailers. Bags that do not meet this requirement may be re-bagged at the fulfillment center at the seller’s expense. Amazon also requires that polybags be at least 1.5 mil thick—thinner bags (1 mil or less) require extra caution and must always carry the suffocation warning.

Walmart’s Thickness-Based Trigger

Walmart takes a different approach: the warning is required specifically for bags less than 1 mil thick (0.001 inch) with an opening of 5 inches or more. Bags thicker than 1 mil do not require the suffocation warning under Walmart’s standards, though they may still need it for state law compliance. Walmart also prohibits polypropylene (PP) import polybags and dry cleaner bags entirely.

Target’s Universal Requirement

Target requires suffocation warnings on all polybags regardless of thickness or opening size. This is the most conservative policy among the three retailers and the safest standard to default to if you sell through multiple channels. Target also requires that polybags be clear, free of BHT (butylated hydroxytoluene), sized to fit the product snugly, and securely sealed.

Warning Placement & Visibility Rules

Where and how you place the suffocation warning is just as important as the text itself. Placement rules vary by retailer and are a common cause of compliance failures—even when the warning text is correct.

General Placement Best Practices

• Print the warning directly on the bag rather than using a separate sticker when possible—stickers can peel off during transit
• Use high-contrast colors (black text on clear or white bag) for maximum readability
• Place the warning where it will be visible without opening the package
• Ensure the warning is not obscured by product labels, barcodes, or seams
• For clear bags, ensure the warning does not overlap with the product inside, making it unreadable

U.S. State Suffocation Warning Laws

While there is no federal mandate, several U.S. states have enacted laws requiring suffocation warnings on plastic bags. These laws generally apply to thin plastic bags sold or distributed within the state, and they specify minimum warning text, font sizes, and sometimes bag thickness thresholds.

States with Suffocation Warning Laws

The following states have specific legislation requiring suffocation warnings on plastic bags. Requirements vary, but all mandate some form of printed warning about the suffocation hazard to children:

• California — Requires suffocation warnings on thin plastic bags; one of the earliest and most comprehensive state laws
• Massachusetts — 105 CMR 630.000 is one of the most detailed statutes, specifying exact font sizes by bag dimension—the basis for most industry font size charts
• New York — Requires warnings on plastic bags distributed to consumers
• Rhode Island — Requires suffocation warnings on plastic bags
• Virginia — Mandates suffocation warnings on bags meeting specific thickness criteria

In addition, some cities and municipalities have their own ordinances, including New York City and Chicago. These local requirements may apply even in states without a statewide law.

Practical Implications for Suppliers

If you sell through retailers that distribute across multiple states, the safest approach is to apply suffocation warnings to all polybags regardless of the destination state. This eliminates the need to track state-by-state requirements and ensures compliance with the most restrictive jurisdictions. This is also the approach Target mandates for all its suppliers.
