About CargoMath
Freight calculations backed by operating experience.
CargoMath is a free logistics calculator platform built and maintained by Honourocean Shipping, an international freight forwarding company based in Shenzhen, China.
Why the site exists
Cross-border sellers repeatedly need the same planning answers: packed CBM, chargeable weight, dimensional weight, customs duty, landed cost, transit time, and freight quote inputs. CargoMath turns those recurring calculations into accessible tools that can be checked before a booking or quotation.
Who maintains it
The project is led by Helenpeng, CEO of Honourocean Shipping Co., Ltd., with logistics experience since 2009. Honourocean reviews the practical assumptions behind the tools and handles freight enquiries submitted through CargoMath.
- Honourocean website for current freight-forwarding services and quote follow-up.
- Honourocean Shipping company site for company background, Shenzhen location, and service scope.
- Honourocean LinkedIn for the public company profile and logistics updates.
- Helen Peng LinkedIn for the public author/operator profile.
Calculation and rate boundaries
CargoMath provides planning estimates, not binding carrier rates, customs rulings, tax advice, or delivery guarantees. Carrier tariffs, exchange rates, classification, origin rules, local fees, and shipment restrictions can change the final result. Dated market ranges are labeled as planning context and should be verified before booking.
From estimate to shipment
When a shipment needs a live carrier check, customs review, DDP scope, Amazon FBA delivery, or dangerous-goods handling, request a freight quote from Honourocean or email the team directly.
