AJC Weekly Brief

China sulphur breaks below CNY 8,000 and the story is demand, not supply; acid absorption is failing to carry sulphur’s cost while India resets the DAP clearing anchor into the low-$900s cashequivalent, urea rebounds post-tender against a 4.5-million-tonne export pipeline, and September MAP/DAP/NPK reopening rumours remain exactly that: rumours without customs evidence.

PVC is one of the world's most widely used plastics: it goes into pipes, window frames, cables, flooring and packaging. China is the world's largest producer, so what happens there shapes prices everywhere, including India. This brief explains, in plain language, where the Chinese PVC market stands right now.

A week after India set its $766 minimum import price, export orders at Chinese PVC producers have dropped 46%. At the same time, Chinese plants are making more PVC than ever with fewer places to sell it.

The rally cools but doesn’t crack; naphtha (+4.9%) and ethylene (+3.8%) extend gains while benzene prints its first weekly decline in three weeks as Europe supplies the structural storyline: the Rhine runs too low for Germany’s crackers, Versalis mothballs Brindisi PE, and Indovinya ties up with Air Liquide on lowcarbon ethylene oxide. 

Chinese producers are selling at a cash loss into record inventory and New Delhi has just drawn a $766/tonne line under the cheapest of those cargoes.

This week's fertiliser market was driven less by simple supply–demand changes and more by execution risk. The Middle East situation has become more complex, with Hormuz and Bab el- Mandeb risks feeding directly into freight, insurance and cargo-execution costs. A sharp decline in Hormuz transits and weaker shipowner confidence are reported, and alternative routes can add around a month at sea while materially raising voyage costs. For fertiliser markets, freight is now one of the fastest-moving indicators — especially for sulphur, ammonia, urea and downstream phosphates.

Lithium carbonate futures in Guangzhou have fallen to a five-month low; not because demand cracked, but because the price rally itself summoned the supply back. Jianxiawo is pouring again, Australia is reopening pits, and Beijing is preparing to tax the very boom that kept prices up.

This week's report shows a firmer tone across China's chemical markets, led by a sharp 15.17% jump in MTBE, along with gains in Propylene Oxide, Hydrochloric Acid, Styrene, and Acetone. The rubber & plastics segment also traded higher — LLDPE, PS, PP, and SBR all posted gains — while energy prices were mixed, with LNG and Diesel firming up but crude oil softening. Liquid Ammonia and Titanium Dioxide were among the few notable decliners.
