Using the tools and guides
Mr Kcal Store provides free planning tools, editable drafts and educational guides. Check your inputs, units, source quotes and the assumptions displayed beside each result.
Calculations and documents
Freight, cost, capacity and duty results are estimates of the information you enter. They do not obtain a carrier booking, establish a customs rate or verify supplier capability. Generated RFQs, specifications, packing lists and proforma invoices need review before use.
External confirmation
Confirm product, commercial, freight, tax, customs and compliance decisions with the relevant supplier, carrier or qualified adviser. Applicable rules and service conditions can change. Keep original quotes and controlled records alongside your working estimates.
Website relationships
MRKCAL Tools is a companion website for PDF, image, text and QR tasks. External links are provided for the described next step; each service has its own supported formats, limits and terms.
Content and corrections
Do not use the website to misrepresent certifications, identities, test evidence or commercial facts. Report a suspected error with a URL and non-sensitive example to mrkcal@mrkcal.com. A public example is not a confidential document review service.
