What ammonium chloride is used for
Ammonium chloride (NH₄Cl, sal ammoniac, salmiac) is a white, odourless crystalline solid that dissolves readily in water. It sublimes on heating, breaking down into ammonia and hydrogen chloride, and it is hygroscopic, so it needs dry storage.
Its main industrial uses are as a nitrogen fertilizer, particularly for rice and wheat, as an electrolyte in dry-cell batteries, and as a flux in preparing metals for galvanizing, soldering and tin coating. It is also a starting material for other ammonium compounds and appears in pharmaceutical and food applications under their own regulatory grades.
Where it fits
- Fertilizer. A nitrogen source for rice, wheat and other crops.
- Batteries. Electrolyte in dry cells.
- Metal preparation. Cleaning and fluxing for galvanizing, soldering and tin coating; a common base for zinc fluxes.
- Chemical manufacture. Raw material for other ammonium compounds.
Handling character
Ammonium chloride is harmful if swallowed and irritating to the eyes. It releases ammonia and hydrogen chloride when heated strongly. Full hazard detail is in the Safety section below.

Importing into the United States
Ammonium chloride is a TSCA-regulated chemical substance, and public references list it on the TSCA Inventory. Under TSCA section 13 the importer of record, or its authorised agent, must certify to US Customs and Border Protection that each shipment either complies with TSCA or is not subject to it. We confirm the substance's Inventory status and agree in writing who files that certification before the first consignment moves.
Which party carries that duty follows the Incoterm. On FOB, CFR or CIF terms it is usually the US buyer; on DDP terms it can be the seller or its agent. Safety data sheets and labels are supplied to OSHA's updated Hazard Communication Standard. Fertilizer and food or pharma uses carry their own state and federal rules, which the buyer confirms for its grade.
| Item | How it works |
|---|---|
| Delivery points | Any nominated US plant, warehouse or port of discharge |
| Incoterms quoted | FOB · CFR · CIF · DDP |
| Importer of record | Agreed in writing before the first shipment |
| TSCA certification | Section 13 certification filed at entry |
| Documentation | Batch COA, SDS, packing list, certificate of origin |
| Pack formats | Bags or FIBC, confirmed at quotation |
Note: regional coverage describes where we deliver, not where we hold inventory. Lead time depends on producer scheduling and ocean transit to your nominated US port — we confirm both in the quotation.
How we supply ammonium chloride
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Purity, moisture and caking behaviour decide whether a lot suits a fertilizer blend, a battery cell or a flux, which shapes how we select producers on this line.
We place your order with whichever qualified producer best matches your grade, price point and delivery window, and confirm US import requirements before booking.
- Grade confirmed before we quote. Purity, moisture and form are checked against your process, not just the headline assay.
- TSCA status and import certification settled first. We confirm Inventory status and agree who files the section 13 certification before the first shipment.
- Moisture-proof packing. Lined packs to hold back moisture and limit caking in transit.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- One desk for the whole range. Order alongside ammonia, hydrochloric acid and Zincflux.
Lined bags against moisture
Ammonium chloride is hygroscopic, so we quote lined, sealed packs. Tell us your preferred format and we will classify to it.
Lined bags
PP-woven or multi-wall bags with a polyethylene inner liner to hold back moisture. Bag size confirmed at quotation.
Liner-fitted jumbo bags
Bulk bags for plants handling material by hoist or bag-tip station.
Incoterms to suit you
Quoted on the Incoterm your purchasing team works to, with documentation filed before booking.
Trial / sample quantities
Small packs dispatched for process qualification before a commercial order is placed.
Harmful if swallowed — keep it dry and handle with care
Ammonium chloride is a non-flammable solid that is harmful if swallowed and irritating to the eyes. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H302Harmful if swallowed.H319Causes serious eye irritation.
Classification varies. Some SDS also list respiratory irritation (H335) and effects from repeated exposure (H373). Follow the SDS for your batch and confirm exposure-limit obligations with your EHS team.
Storage
Store in closed containers in a cool, dry, well-ventilated area, away from moisture, strong bases, strong acids and oxidisers. Keep bags sealed between uses to avoid caking.
Handling
Avoid inhaling dust, wear eye protection and gloves, and keep washings out of drains. Strong heating releases ammonia and hydrogen chloride, so ventilate hot processes.
Transport
We confirm and document the exact transport classification and routing for your shipment and destination from the SDS.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Purity, moisture and form confirmed against your process requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and TSCA certification data checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How ammonium chloride is made
Ammonium chloride is made industrially by reacting ammonia with hydrochloric acid, or by double decomposition, for example from sodium chloride and ammonium sulphate. The latter route gives sodium sulphate as a co-product.
Crude product is dissolved, filtered, cooled to crystallise, centrifuged and dried to give the technical crystal. Using ammonia and hydrochloric acid as feeds ties it to the same chemistry as our urea and potassium chloride fertilizer lines.
We do not publish operating process parameters here; this is background only. Full technical documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
