Import Ammonium Sulphate — Buy in Bulk from Supplier in Canada

M Trading supplies ammonium sulphate from Canada as a white crystalline powder with assay of minimum 99.5 percent (NH4)2SO4, CAS number 7783-20-2. The material meets tight impurity limits: arsenic not more than 0.00002 percent, calcium not more than 0.001 percent, magnesium not more than 0.0005 percent, and heavy metals as lead not more than 0.0002 percent. The pH value is minimum 4.5, indicating the acidic characteristic that makes this grade effective for alkaline soil amendment. This Canadian-origin material is offered in powder form rather than granular, which affects spreadability and dissolution rates in field application.

The product specification covers chloride at not more than 0.0003 percent, nitrates at not more than 0.001 percent, iron at not more than 0.0002 percent, and phosphate at not more than 0.0005 percent, with non-volatile substances capped at 0.01 percent. These analytical-grade limits suggest suitability for applications beyond bulk agriculture where trace-element control matters, including certain industrial processes and precision agriculture. The low nitrogen content relative to ammonium nitrate, approximately 21 percent nitrogen by weight in the sulphate form versus 34 percent in the nitrate, is a known trade-off that buyers factor into their nutrient cost calculations and transport logistics. Standard industrial-grade ammonium sulphate typically carries 20.5 to 21 percent nitrogen and 24 percent sulphur, though buyers should verify current certificates of analysis for each shipment.

Primary applications span alkaline soil fertilisation, where the ammonium ion releases and generates acidity to counter high pH substrates, and agricultural spray adjuvant use for water-soluble insecticides, herbicides, and fungicides. Industrial buyers include fertiliser blenders, large-scale farming operations in semi-arid regions, and pesticide formulation companies seeking a compatible salt carrier. Importers should confirm with M Trading whether the powder form is milled to a specific particle size distribution, as this affects both flowability in mechanical spreaders and dissolution kinetics in spray tank mixes. The supplier lists a response rate of zero percent, so buyers should expect to initiate contact through alternative channels and verify current availability and packaging options directly.

M Trading is listed as an imported supplier tier with a harbour trust designation, indicating the entity sources product into the Canadian market rather than manufacturing domestically. The supplier profile shows a response rate of zero percent and an average response time of zero hours, which means no response data is currently available through the platform. The business name "M Trading" suggests a trading house rather than a production facility, consistent with the imported supplier classification. No additional corporate history, employee count, revenue figures, or client references are present in the source data.

The supplier's address and specific office location are not provided in the available profile, so buyers will need to request full contact and registration details directly. The harbour trust tier is a baseline verification level, so importers should conduct independent due diligence including request for business registration, tax identification, and references from previous transactions. M Trading lists ammonium sulphate in powder form with analytical-grade specifications, which may indicate access to refined or technical-grade material rather than standard bulk fertiliser. Buyers should clarify whether M Trading holds stock in Canada or arranges direct shipment from overseas production sites, as this affects lead times, customs clearance responsibilities, and Incoterms applicability.
