Trading entities
Check that the legal name on any invoice you receive matches the entity you contracted with, and that the bank account name matches it too.
Send your specification as a list. Grade, form, particle size, packaging, quantity, port, trade term, documents. A structured enquiry usually saves several rounds of clarification.
Contacting us — common questions
What information should I include in my inquiry?
Product and grade, physical form, particle size if relevant, packaging, quantity, destination port, trade term and any document requirement. With those, we can answer with availability and a quotation rather than a clarification question.
How quickly will I get a reply?
Inquiries are normally answered within one business day. Inquiries that require checking availability for a specific particle size, or a document that is unusual for the destination, may take longer — but you will get an answer.
Can I send my inquiry on WhatsApp?
Yes. WhatsApp is often the fastest route, particularly if you want to send a specification document or a photograph of a packaging requirement.
