Dart Insulated Beverage Cups 16 fl oz 20 Count
Skip, insulated foam cups often use PFAS coatings; Dart does not disclose, making assessment impossible.
Dart's insulated beverage cups are polystyrene foam with a coating to resist moisture and grease, a classic PFAS-risk profile. Dart Container provides no public disclosure about PFAS presence, alternatives, or testing. Without lab data or brand transparency, the waterproof barrier coating's chemistry remains unknown and warrants caution.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
