Ammonium sulfate week 43, 2026: the allocation arrived, the tonnage did not

Ammonium sulfate, 29 October 2026: the second allocation finally has a tonnage, and the compactor share is the number that decides Brazil

A number appeared this week where last week there was only a rumour: 1.3-1.7mn t, about a third of the first round. But the headline tonnage is not the tradeable number. The split is — and if compactors get 40pc, Brazil is the market that feels it first.

Ammonium sulfate, 28 October 2026: the second allocation is out and the offers have not moved

A second export allocation was released and the price did not move. That is not a quiet market — it is a market where allocation changed hands but not volume, and the difference decides who pays for freight in the first quarter.

China Ammonium Sulfate Market Splits Into Two Tiers

China's ammonium sulfate market has split in two. Export-grade caprolactam material trades at $210-215/t fob and is firming, while tonnage that fails export inspection floods back inland and caps domestic prices.

Before you enquire

Six things to have ready

A quotation you can act on needs these six items. A structured enquiry normally avoids a clarification round and gets a usable answer the first time.

1

Product and grade

Ammonium sulfate, and the analysis you require — normally 21-0-0-24S. See production sources.

2

Physical form

Granular or crystalline, stated explicitly. See the comparison.

3

Particle size

If you blend or use mechanical spreaders, give the range your process needs.

4

Packaging

25 kg, 50 kg, jumbo bags or bulk — see the packaging guide.

5

Quantity

A trial container, or a programme. If it is a programme, a monthly profile helps.

6

Port and trade term

Destination port, and the trade term you want to work on — FOB, CFR or CIF.
