Grosmimi PPSU Straw Cup with Flip Top - 10oz (12 Months+) Stage 2 Straw

The bottle body is named as PPSU, and blog content ties this specifically to premium PPSU polymer properties (heat resistance to 392°F, chemical stability under sterilization), though no specific resin supplier (e.g., BASF/Solvay) is named.

The cup body and straw are both named as PPSU, an FDA-compliant material, and this cup is free of BPA, BPS, and BPF, going beyond a bare BPA-free claim to cover the known bisphenol substitutes.

This cup is sold in printed designs such as Dino Khaki, Unicorn and Air Balloon, and no lead testing of the printed exterior is published anywhere.

The brand gives a concrete replacement interval for the silicone straw (every 2-3 months) and confirms sterilization and dishwasher compatibility, but the cup body itself carries no stated replacement interval or method for detecting degradation.

The straw is named as platinum silicone, the same material used in Grosmimi's baby nipples, with a stated replacement interval of every 2-3 months for hygiene, though no medical-grade biocompatibility standard (ISO 10993/USP Class VI) is cited.

We queried the complete CPSC recall database — 10,027 records spanning 1973 to 2026 — and found no record naming this brand in any role. A control search confirms the corpus covers comparable product classes, so the clean result reflects the brand's actual absence from the registry. A third-party claim of a 2019 recall over detachable spouts is not corroborated anywhere in that regulator data.

The brand publishes a concrete replacement interval of every 2-3 months for the silicone straw and teat parts for hygiene, with inspection guidance to discard at first signs of damage or weakness.

The finished cup's PPSU material is FDA-compliant and BPA/BPS/BPF-free, and other Grosmimi straw products are CPSIA-compliant and tested by CPSC-verified laboratories, a named standard asserted with no published certificate number.

The brand discloses that products are designed, tested and manufactured in Korea with consistent batch tolerances, and publishes a concrete 1-year warranty against manufacturing defects with no-questions-asked replacement for leaks or material degradation.
