Yes, you can get pierced with bioplast.
"Biocompatible polymers (plastics) including Tygon® Medical Surgical Tubing S-50HL or S-54HL, PTFE (Teflon®), or Bioplast™ are considered suitable for new piercings. Tygon is a bio-compatible medical tubing that is highly flexible. It should be changed every few months as it stiffens and discolors from extended wear. PTFE, a white plastic, is widely accepted within the industry. Bioplast was created specifically for piercings and is similar to PTFE, but comes in an array of colors and shapes. These may be worn as a substitute for metal jewelry. With new polymer products coming into the marketplace, check that the product you are purchasing, if not listed above, is USP VI compliant. These can be sterilized in an autoclave."
