Injection Stretch Blow PET 73 IV
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the PET has an intrinsic viscosity of 78 ml/g or higher
Tariff item 3907.61.00 covers poly(ethylene terephthalate) with a viscosity number of 78 ml/g or higher, so a higher IV would shift classification.
If the resin is chemically modified or contains significant additives
Chemically modified PET or PET with substantial non-polymeric substances may fall under other polyesters in primary forms.

Import Tips & Compliance
• 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
