This is what a buyer checks before they shortlist a chemicals and materials supplier.

What does a buyer check before importing a fertilizer grade?

They check the guaranteed nutrient analysis, the heavy metal and contaminant limits against their market's rules, and whether the product is registered for sale there. Fertilizer is a regulated commodity, so registration and analysis decide the trade before price does.

An importer is checking whether a grade can legally and profitably enter their market before the season.

Every claim on a supplier site has a document behind it or it does not. Buyers in fertilizers know which is which.

What a buyer needs to identify the product

These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.

  1. 1

    Grade and guaranteed analysis

    The nitrogen, phosphorus and potassium content buyers trade on.

  2. 2

    Secondary and micronutrient content

    Increasingly a differentiator rather than an afterthought.

  3. 3

    Physical form

    Prilled, granular, crystalline and liquid affect spreading and blending.

  4. 4

    Particle size distribution

    Determines blending compatibility and segregation risk.

  5. 5

    Moisture and caking behaviour

    Decides storage and shipping season.

  6. 6

    Packaging

    Bulk, jumbo bag and retail bag are different markets.

  7. 7

    Origin and production route

    Affects duty treatment and buyer perception.

The documents buyers ask for

Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.

Where fertilizers sites lose the enquiry

Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.

  • Nutrient analysis given as a typical value with no guarantee

    Fertilizer is traded on guaranteed analysis with tolerances. A typical value is not a commercial position and buyers treat it as one that cannot be honoured.

  • No heavy metal data

    Several markets set hard cadmium limits. A supplier who cannot produce the data is assumed to fail them.

  • Registration status not stated by market

    An unregistered product cannot be sold, so an importer will not begin a commercial discussion without knowing where it stands.

What the enquiry form should ask

A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.

Enough to reply usefully, short enough that a buyer finishes it.

Grade and analysis required
Determines whether you can supply.
Quantity and packaging
Bulk and bagged are different logistics and prices.
Destination port and market
Registration, duty and inspection all follow it.
Shipment schedule
Fertilizer demand is seasonal and unforgiving.
Inspection requirement
Third-party inspection needs arranging at load port.
Documentation required
Certificates of origin and analysis vary by market.

Questions suppliers ask

Should we publish typical or guaranteed analysis?

Guaranteed, with the tolerance. That is the basis on which the trade is contracted and inspected, and publishing a typical value instead suggests the guarantee would be a negotiation. It also protects you at the inspection stage, because the published figure is the one you can meet.

How do we present origin without limiting our market?

State it plainly. Origin affects duty, buyer preference and sometimes eligibility, and it will emerge on the certificate of origin regardless. Buyers who cannot accept the origin were never going to complete, and those who can often prefer knowing early.

Is registration status worth publishing market by market?

Yes, as a table. Importers filter suppliers on it before anything else, and a table saves them an email while making you the supplier who is easy to evaluate. Where a registration is pending, say so and give the stage.

Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
