BIBS Grow & Flow Baby Bottle Set, 5oz + 9oz — Ivory

The bottle body is named as BPA-free polypropylene, but no resin grade or supplier is disclosed, and no external verification or replacement guidance specific to the body material's degradation is given.

The bottle body and its accessory parts (caps, milk lock) are disclosed as polypropylene that is free from BPA, BPS, and PVC, going beyond a bare BPA-free claim to name the structural bisphenol replacements as absent.

The bottle body is molded from borosilicate glass or BPA-free polypropylene; the CPSC record for this brand's glass bottle line describes an exterior measuring guide and brand name printed directly on the glass. No lead or heavy-metal test result for that surface marking is published, and no material spec confirms this particular set's body or surface finish.

A concrete nipple replacement schedule is published, and the brand names scratching and heat-driven deformation as real degradation modes for the PP bottle, but no shedding or migration data at use temperature is given for the plastic body.

The nipple is named as either medical-grade silicone or natural rubber latex, and latex has natural-material aging trade-offs (sensitivity to sunlight, heat, and moisture causing brittleness or stickiness over time).

The recall registry covering 1973 to 2026 holds one entry for this brand: a BIBS glass bottle bumper recalled for a burn hazard, about 300 units, with no injuries reported and a remedy offered to owners. That recall reached the glass bottle line, a different bottle body from this polypropylene set.

A concrete replacement interval is published by nipple material — silicone nipples every 8-12 weeks, latex nipples every 4-8 weeks — along with specific degradation signals (surface changes, ruptures, brittleness, stickiness) that should trigger replacement.

The bottle set itself carries no named finished-product certification; the ISO 9001/14001 certificates found relate to quality/environmental management systems, not food-contact safety, and the EN 1400+A2 standard cited applies to pacifiers, not this bottle set. No method or result is given for the bottle itself.

The bottle set's component materials (funnel, milk lock, nipple options) are named, but country of manufacture and warranty terms are not published for the bottle line specifically — country of manufacture is only stated for pacifiers.
