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.

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.
