Philips Avent

Specs clearly published Made in China usa.philips.com/c-m-mo/avent ↗

The default Philips Avent Natural bottle is polypropylene with a silicone nipple, so the entire milk vessel is plastic. A glass version of the Natural exists, but even there the screw ring that seats the nipple is plastic. Philips is transparent that its bottles and parts are BPA-free, but the standard bottle is a plastic vessel through and through - BPA-free is an additive claim, not a material one.

How clear are their specs?

Philips publishes a support page listing exactly what each part is made of (polypropylene bottle, silicone nipple) and describes the plastic screw ring on the glass model. Materials are disclosed clearly; the framing just leans on "BPA-free" over "plastic."
