SITCSection 5
U.S. imports of xylenes, pure (SITC 51124) totaled $64.1M in July 2026, traded with 15 countries.
Importers of Xylenes, Pure paid $6.3M in duties in July 2026 — an effective duty rate of 10% on $62.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Xylenes, Pure imports of $64.1M in July 2026 ran 21% above the year-to-date monthly average of $53.1M.
Last updated: July 2026 dataPure xylenes — encompassing ortho-, meta-, and para-xylene isomers — are high-volume aromatic intermediates central to the production of polyester fibers, PET resins, and phthalate plasticizers, making them strategically important to the packaging and textile industries. Para-xylene (PX) commands the largest commercial volumes and is the primary feedstock for purified terephthalic acid (PTA). Importers should note that xylene isomer composition affects both classification and downstream processing value, and TSCA certification is required at US entry.

The SITC heading covers xylenes broadly, but individual isomers — ortho-, meta-, and para-xylene — may be distinguished at the HTS tariff-line level for duty purposes. Importers should specify the isomer composition on commercial documentation and confirm the applicable HTS code with a licensed customs broker, as para-xylene and mixed xylenes can carry different tariff treatments.
Para-xylene is the direct feedstock for purified terephthalic acid (PTA), which is in turn the primary monomer for PET plastic and polyester fiber. This downstream demand from the packaging and textile industries makes PX the highest-volume and most price-sensitive xylene isomer in global trade, and supply disruptions can ripple quickly into PET resin and fiber markets.
