U.S. imports of poly(ethylene terephthalate), viscosity 78 ml/g or higher (HS 390761) totaled $106.7M in April 2026, traded with 44 countries.
Importers of Poly(Ethylene Terephthalate), Viscosity 78 mL/g or Higher paid $11.0M in duties in April 2026 — an effective duty rate of 14% on $76.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataHigh-viscosity PET resin—defined by an intrinsic viscosity of 78 mL/g or higher—is the bottle-grade and fiber-grade workhorse of the polyester supply chain, used in beverage containers, food packaging, and textile filaments. The US schedule further subdivides this heading: 3907610010 covers viscosity from 78 to below 88 mL/g, while 3907610050 covers viscosity above 88 mL/g, distinctions that matter for end-use qualification and duty treatment. Mexico is the leading US import source, followed by Taiwan and South Korea. Importers should note that PET from certain origins has historically been subject to antidumping duty orders, making supplier origin verification a critical compliance step.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The 78 mL/g intrinsic viscosity threshold separates bottle- and fiber-grade PET (3907.61) from lower-viscosity grades used in films and coatings (3907.69). Intrinsic viscosity is typically measured by solution viscometry per ASTM D4603 or equivalent ISO methods. Importers should obtain the supplier's certificate of analysis confirming the IV value, as misclassification between 3907.61 and 3907.69 can affect both duty rates and antidumping order applicability.
Yes. The US has maintained antidumping duty orders on PET resin from several countries over the years. Importers must check current Commerce Department and ITC orders to determine whether their specific origin and product are covered, and should be prepared to post antidumping duty deposits at entry. A licensed customs broker can assist with scope rulings if the product's coverage is uncertain.
