Report Industry Investment Rating - PX/PTA/PF/PR are rated neutral [4] Core Viewpoints - The postponement of the maintenance of two PX units has narrowed the de - stocking range of PX in the fourth quarter, weakening the previous de - stocking support.

The demand recovery is limited, and the polyester load increase is restricted [2] - The polyester start - up rate shows signs of recovery, but order connection is insufficient. It is expected that the polyester load will remain stable with a slight increase in September [2] - The short - term supply - demand situation of direct - spinning polyester staple fiber is better than that of the raw material end, and the processing margin has widened. The bottle - chip processing fee is expected to fluctuate slightly, and there is still large supply - demand pressure under the new device commissioning [3] - For the strategy, it is recommended to go long on the PF processing fee at low prices in cross - variety trading, and there is no recommendation for cross - period trading [4] Summary by Directory Price and Basis - The report shows the TA main contract, basis, and inter - period spread trends; PX main contract trends, basis, and inter - period spread trends; PTA East China spot basis; and short - fiber 1.56D*38mm semi - bright natural white basis [9][10][13] Upstream Profit and Spread - The report presents PX processing fee PXN, PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [16][19] International Spread and Import - Export Profit - The report includes toluene US - Asia spread, toluene South Korea FOB - Japan naphtha CFR, and PTA export profit [24][26] Upstream PX and PTA Start - up - The report shows the PTA load in China, South Korea, and Taiwan, as well as the PX load in China and Asia [27][30][34] Social Inventory and Warehouse Receipts - The report presents the weekly social inventory of PTA, monthly social inventory of PX, total PTA warehouse receipts + forecast volume, PTA warehouse receipt inventory, PX warehouse receipt inventory, and PF warehouse receipt inventory [36][39][45] Downstream Polyester Load - The report shows the production and sales of filament and short - fiber, polyester load, direct - spinning filament load, polyester staple fiber load, polyester bottle - chip load, factory inventory days of various filaments, and the start - up rates of Jiangsu and Zhejiang looms, texturing machines, and printing and dyeing machines, as well as the profits of filament FDY and POY [49][51][62] PF Detailed Data - The report presents the polyester staple fiber load, factory equity inventory days of polyester staple fiber, 1.4D physical inventory, 1.4D equity inventory, recycled cotton - type staple fiber load, original - recycled spread, pure polyester yarn start - up rate, pure polyester yarn production profit, polyester - cotton yarn start - up rate, polyester - cotton yarn processing fee, and the available inventory days in pure polyester yarn and polyester - cotton yarn factories [71][73][83] PR Fundamental Detailed Data - The report shows the polyester bottle - chip load, bottle - chip factory inventory days, bottle - chip spot processing fee, bottle - chip export processing fee, bottle - chip export profit, price difference between East China water bottle chips and recycled 3A - grade white bottle chips, and bottle - chip inter - month spreads [91][93][101]
