Ammonium sulfate: the cheap offers are gone, not the demand

China standard caprolactam-grade ammonium sulfate held at $205-210/t fob in our latest read. The headline number did not move, and right now it is the least informative number on the page.

The cheap end of the market is what moved.

The low grades repriced first

A domestic MMA-grade tender in Shandong was awarded at ¥1,080/t ex-works, against roughly ¥965/t a week earlier. That is about $178/t fob equivalent — close to $18/t higher in a week, on the grade that normally sits at the bottom of the offer stack.

Domestic caprolactam-grade in Shandong held at ¥1,280/t ex-works, about $207/t fob equivalent. Flat, after two weeks of increases.

Separately, two suppliers we monitor have withdrawn their standard offers entirely, saying they have no export availability to sell. Compactors have largely used up their allocated raw material and have slowed restocking rather than adding to it.

A flat headline sitting on a rising floor describes a particular kind of market. It is not a market where buyers are paying up. It is a market where the sellers who still hold material have stopped competing on price, and the ones without material have stopped quoting. Neither of those is a demand signal.

If you are benchmarking against the headline grade and assuming the market is quiet, you are reading the wrong line.

Why nobody is discounting

Shandong ex-works at $207/t fob equivalent, against an export assessment of $205-210/t fob. That is the second assessment in a row where the two numbers are effectively the same.

Parity explains why offers are being withdrawn instead of sharpened. A producer selling at parity is exporting to keep a route open, not to earn a margin — so there is nothing left to concede. It also means the current export level is being capped by the domestic Chinese market rather than by what an overseas buyer is willing to pay, which is the main reason we do not expect a correction to arrive from the demand side. Our September analysis of the move sets out how that parity developed.

The part buyers are missing

If you buy compacted material for Brazil, the standard-grade headline is not your market.

Brazil cfr compacted was assessed at $250-260/t with no new business confirmed, and compacted fob China sits at $210-225/t. Both are firm, and both depend on Chinese compactors having raw material to work with. At the moment they are running down allocations rather than building them up. That points to tighter compacted supply into October and November, not looser — and it will not show up in the standard-grade number at all.

There is a cost angle underneath this as well. Sulphur has moved up sharply on both the Tampa and North Africa benchmarks in recent weeks. Sulphur sets the cost floor for material produced the synthetic route — ammonia plus sulphuric acid — and synthetic material is what normally fills the bottom of the offer stack when by-product grades are tight. That floor is rising at the same time the bottom of the stack is emptying out. Our production source guide covers why those routes do not substitute for one another.

One thing worth pushing back on

The EU’s temporary removal of its 6.5% import duty on urea is widely read as bullish for nitrogen, and for urea it is. For ammonium sulfate it cuts the other way. Cheaper urea narrows the cost-per-unit-nitrogen gap that has been steering sulfur-hungry buyers toward ammonium sulfate in the first place. Cheap urea and a firm ammonium sulfate market are not the same trade, and European demand may prove less of a support for this market than the urea headlines imply.

What we would do

Ask for allocation, not a price. In the current state those are two different questions, and only one of them has an answer today.

Check that your benchmark is still the right one. If the standard headline is flat while the lower grades have moved $15-20/t, the substitution comparison you ran a month ago is already out of date. The specification guide lists the parameters worth qualifying before you compare prices across grades.

Treat every CFR figure as parcel-specific. Brazil cfr has held while fob rose, which means freight is absorbing the difference. A delivered number quoted for one parcel size does not transfer to another.
