BPA-free does not mean plastic-free. It describes a claim about bisphenol A, while a product can still be made from other plastics or include plastic components.
Read the label precisely
| Label or mark | What it tells you | What it does not tell you by itself |
|---|---|---|
| BPA-free | The maker is making a claim about BPA | That the item is free of all plastics or other materials |
| Resin identification code | A code identifies the plastic resin type | Whether a local program accepts that item for recycling |
| Material list | The components or materials the maker names | Details the maker has not disclosed |
| Food-contact statement | A claim about intended food use | Every care limit or every component’s composition |
The FDA’s BPA consumer page discusses BPA in food-contact applications and explains that resin identification marks are a limited clue. A material claim should not be stretched beyond the wording the maker provides.
Product-label checklist
- Look for the full material list, including lid, seal, coating and interior components.
- Check whether the maker identifies the specific resin or grade.
- Read the care instructions for heat, dishwasher and microwave limits.
- If a component is unclear, ask the manufacturer for that part’s material.
Browse food storage, compare glass and stainless storage, and read whether stainless tumblers have plastic lids.

Common questions
Does BPA-free mean the product contains no plastic?
No. BPA-free refers to bisphenol A. A product can use other plastic resins or have plastic components.
Does a resin number prove a container contains BPA?
No. FDA says resin identification can signal that BPA may have been used in some contexts, but the mark is not a complete chemical disclosure.
How can I learn a product’s material?
Read the maker’s material list and care instructions, and ask the maker about components that are not identified.
