For US licensed customs brokers, international trade compliance directors, and logistics managers handling secondary polymers, importing post-consumer recycled Polyethylene Terephthalate (pet flakes) requires strict tariff precision.
With US domestic demand for high-grade recycled resin climbing under aggressive state minimum post-consumer recycled (PCR) laws, converters and compounders are increasingly turning to overseas mechanical recyclers.
However, moving bulk industrial polymers through major US ports of entry—such as Los Angeles/Long Beach, Newark, Savannah, and Houston—comes with heightened regulatory scrutiny from US Customs and Border Protection (CBP).
A minor documentation error, a miscalculated trade preference claim, or an inaccurate tariff classification can trigger expensive customs holds, intensive cargo examinations (VACIS exams), and steep penalty assessments under 19 U.S.C. § 1592.
Avoiding these costly delays requires mastering the nuances of HTS code PET flakes US customs import filings.
Classifying post-consumer bottle flakes correctly under Chapter 39 of the Harmonized Tariff Schedule of the United States (HTSUS), understanding country-of-origin rules, and optimizing entry documentation allows trade compliance teams to ensure fast entry clearance without administrative holds.
This trade compliance and logistics guide breaks down US tariff classifications for rPET, analyzes duty structures and Section 301 considerations, and explains how Key Mart Limited provides audit-ready export documentation directly from Dhaka.
1. HTSUS Classification for Recycled PET: Subheading 3915.90 Analysis
Proper customs clearance begins with determining the correct 10-digit statistical reporting number within the Harmonized Tariff Schedule of the United States:
Clear Post-Consumer Bottle Feed ➔ Hot-Caustic Wash & Granulation ➔ US Customs Entry Filing (CBP Form 7501) ➔ HTSUS 3915.90.0000 Classification ➔ Duty Calculation & ACE Clearance ➔ Rapid Terminal Release
A. The Core Classification: Chapter 3915 vs. Chapter 3907
-
Heading 3915 (“Waste, parings and scrap, of plastics”): The legally mandated tariff heading for mechanically ground, washed, and dried flakes derived from post-consumer PET bottles.
-
Specifically, recycled PET bottle flakes enter under HTSUS 3915.90.0000: “Waste, parings and scrap, of plastics: Of other plastics.”
-
-
The Tariff Distinction (Why Not 3907?): Primary forms of virgin or re-pelletized Polyethylene Terephthalate fall under Heading 3907 (“Polyacetals, other polyethers and epoxide resins… poly(ethylene terephthalate)”).
-
The Regulatory Borderline: If flakes undergo solid-state polycondensation (SSP) or re-extrusion into uniform spherical/cylindrical pellets before export, CBP considers the material transformed into a primary form (Heading 3907), altering the applicable statistical reporting number and duty rate. Ground bottle flakes that remain in irregular chip form are classified under 3915.90.
B. General Duty Rates and Section 301 Exemption
-
General Column 1 Duty Rate: The standard MFN (Most-Favored-Nation) duty rate for HTSUS 3915.90.0000 is Free ($0.00\%$).
-
Section 301 Tariffs (The China Trade Surcharge): Plastic scrap imported from mainland China remains subject to punitive Section 301 tariffs of up to 25% under List 3.
-
The Bangladesh Advantage: Sourcing from Bangladesh gives US importers a decisive tariff advantage. Because Bangladesh is not subject to Section 301 actions on plastic scrap, imports under HTSUS 3915.90 enter the US completely free of Section 301 duties, dramatically lowering landed procurement costs.

2. Preventing CBP Holds and Automated Broker Interface (ABI) Flags
Customs brokers and freight forwarders can ensure predictable clearance cycles at container terminals by following three standard filing protocols:
-
Explicit Commercial Invoicing Disclosures: The commercial invoice and ocean bill of lading must state: “100% Post-Consumer Recycled Polyethylene Terephthalate (PET) Flakes, Mechanically Washed and Air-Elutriated, Non-Pelletized Flake Form, HTSUS 3915.90.0000.” Removing ambiguous phrases like “plastic scrap” or “recycled resin” prevents CBP automated cargo-targeting algorithms from flagging the container for mandatory x-ray or physical examinations.
-
EPA TSCA Title VI and Hazardous Waste Compliance: Ground PET flakes derived from food and beverage containers are not classified as hazardous materials or toxic substances under the Toxic Substances Control Act (TSCA). Providing an explicit TSCA Positive Certification statement on corporate letterhead accelerates ACE automated broker releases.
-
Third-Party Chain-of-Custody Documentation: Customs audits evaluate the declared value and origin of imported merchandise. Having an accredited Global Recycled Standard (GRS 4.0) transaction certificate ready proves the post-consumer collection origin, eliminating CBP questions regarding transshipment or misclassification.
