Injection Stretch Blow PET 73 IV from Japan
Injection Stretch Blow PET 73 IV is a polyethylene terephthalate resin in primary pellet form, precisely formulated with an intrinsic viscosity of 73 ml/g for two-stage injection stretch blow molding of PET containers. This viscosity level optimizes preform reheating and enables a 40x stretch ratio, ensuring consistent wall thickness and clarity in finished bottles. It is classified under tariff item 3907.69.00 as other poly(ethylene terephthalate) in primary forms.

Import Tips
• Ensure the certificate of analysis clearly states the intrinsic viscosity of 73 ml/g, as this determines classification under 3907.69.00
• Keep records of the polymer composition to confirm PET content exceeds 95% by weight
• Verify whether the resin contains additives exceeding 1% by weight, which may affect the tariff classification
