Polyester (PET) Chips

Different markets and grades provide context. They are not direct quotes for this material.

Monthly estimates through Oct 19, 2026. Historical figures have not been independently revalidated. Carried-forward months after that date are omitted.

The range uses a public SunSirs China PET spot observation converted from RMB to USD. It is a domestic-market proxy, not a directly assessed fiber-grade import price. Grade, tax basis, exchange rate and delivery terms must be matched before comparing it with a supplier quote.

We check sources weekly. If a source cannot be verified, its previous value and date remain visible without implying that the market was unchanged. Published dates refer to observations; source checks have their own date.

Prices and analysis are for market context. Confirm a current quote for your grade, origin, tax and delivery terms before making a purchasing decision.

PET (polyethylene terephthalate) is the plastic behind polyester. It arrives as small chips made from two chemicals — PTA and MEG — and in furnishings becomes rug face yarn, upholstery fabric, curtains, and the fibre fill inside cushions and mattresses. A growing share is recycled (rPET) from bottles.

The chips are melted and spun into yarn — continuous BCF filament for machine-made rugs, or staple fibre for softer textiles. Carpet-grade chips need higher molecular weight (IV ~0.85–1.05) than apparel-grade so the pile resists crushing. Colour can be locked in at spinning, just like PP.

Polyester yarn spinners and the mills they feed: rug producers in Turkey (where SASA supplies much of the domestic chip), Egypt, India and China, plus home-textile and upholstery makers worldwide. China dominates global chip output, which is why its domestic print is the benchmark everyone watches.

• Oct 19, 2026Updated the China PET proxy to the October 19 SunSirs observation: the indicative range is $1,299–1,343/ton, from $1,303–1,347. PTA and MEG each fell more than 2% on the day. Polyester staple is observed again now that its source page loads. Grade and tax basis remain unverified.
• Oct 15, 2026Added the native SunSirs China PET print (CNY/ton) as its own benchmark next to the USD indicative range. Feedstock changes are now compared with the previous daily print. Polyester staple is carried because its source page could not be loaded.
• Oct 15, 2026Corrected the polyester staple fiber label: the source page gives no 1.4D specification, so it is now shown as China spot with the spec not stated.
• Oct 15, 2026Updated the China PET proxy from the October 15 source observation and dated exchange rate. The indicative range is $1,303–1,347/ton. Grade and tax basis remain unverified; this is not a confirmed fiber-grade or Turkey import quote.
• Sep 14, 2026SunSirs China PET chip spot print (8,651.25 RMB/ton) converted to a $1,268–1,312/ton headline band, up ~5% from $1,206–1,250, as Brent surged to a 4-month high of $109/bbl on Saudi Arabia pipeline disruption from drone attacks and the Chinese polyester chain firmed broadly (PTA +8.3% w/w, MEG +2.7% w/w, PSF +4.4% w/w, POY +1.8% w/w).
• Sep 7, 2026SunSirs China PET chip spot print (8,242.92 RMB/ton) converted to a $1,206–1,250/ton headline band, up ~5.2% from $1,145–1,189, as Brent jumped to $97/bbl and the Chinese polyester chain firmed on balance (MEG +0.5%, POY +3.1%, PSF +5.3% w/w) despite a modest PTA pullback (-1.8% on the day).
• Aug 31, 2026SunSirs China PET chip spot print (7,854.84 RMB/ton, direct producer-average series — a fresher feed than the prior Sanfangxiang/Wankai quotes) converted to a $1,145–1,189/ton headline band, up ~3.6% from $1,104–1,148, as PTA (+1.5%) and polyester staple (+0.9%) firmed and Brent jumped 2.7% on renewed Iran sanctions risk; MEG and POY held roughly flat.
• Aug 24, 2026SunSirs China PET chip print (~7,565 RMB/ton, latest free Sanfangxiang/Wankai producer quotes) converted to a $1,104–1,148/ton headline band, up ~3.7% from $1,064–1,108 as PTA/MEG/PSF/POY feedstocks all rose 4–9% together, unwinding July's softening.
• Jul 20, 2026SunSirs China PET chip print rose ~3.5% to a $1,067–1,112/ton band as PTA/MEG/POY feedstocks jumped 5–13% on renewed Iran-US Mideast conflict; Brent up ~21% over the same window.
