High Viscosity PET Resin Pellets
Granular polyethylene terephthalate (PET) resin with a viscosity number of 78 ml/g or higher, used primarily for producing high-strength bottles and packaging films. This falls under HTS 3907.61.00.50 as PET in primary form meeting the specified viscosity threshold, classified as 'Other' within the high viscosity series.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If viscosity number below 78 ml/g
Lower viscosity PET falls into the preceding subheading for film and sheet production.
If chemically modified with significant non-PET comonomers
Modifications or copolymers not predominantly PET shift to 'Other' polymers in Chapter 39 series per subheading notes.
If classified as unsaturated polyester rather than PET
Different polyester types like alkyds or polyallyl esters use separate subheadings.

Import Tips & Compliance
• Verify intrinsic viscosity (IV) through lab testing to confirm ≥78 ml/g, as documentation is required for classification
• Provide certificates of analysis showing monomer composition where PET units exceed 95% by weight per Chapter 39 notes
• Avoid misdeclaration as lower viscosity PET (3907.60), which could trigger audits and penalties
