Get in Touch

Email: tarsis.global@gmail.com

I read every message personally. I aim to respond within 2 to 3 business days. Due to the volume of inquiries received, I may not be able to reply to every message individually — but I review all feedback and use it to improve the content published on TradeEdge.

What I Can Help With

TradeEdge covers the following topics in depth, and I welcome questions related to any of them:

  • Freight forwarding concepts and terminology
  • Ocean freight — FCL, LCL, container types, port procedures
  • Air freight — chargeable weight, MAWB, HAWB, air cargo handling
  • U.S. Customs and Border Protection (CBP) procedures and documentation
  • HTS code classification and duty rate research
  • Incoterms 2020 — which rule applies to your shipment and why
  • Landed cost calculation — duties, freight, fees, and surcharges
  • Demurrage and detention — understanding charges and free time
  • Bills of lading, airway bills, commercial invoices, and packing lists
  • ISF filing requirements and CBP compliance
  • Cargo insurance — ICC-A, ICC-C, CIF vs CIP coverage
  • Port fees, terminal charges, and delivery coordination
  • Suggestions for topics you would like to see covered on the blog
  • Corrections or feedback on existing TradeEdge articles

What I Cannot Help With

TradeEdge is an educational resource — not a licensed customs brokerage or freight forwarding operation. Through this site, I am not able to:

  • Book, manage, or track your active shipments
  • File customs entries or ISF filings on your behalf
  • Act as your customs broker or freight forwarder of record
  • Provide formal legal or financial advice

For active shipment needs, please work directly with a licensed customs broker or freight forwarder in your area. If you need help evaluating or selecting one, TradeEdge has published a practical guide on what to look for when choosing a customs broker.

Consulting Inquiries

I offer limited consulting engagements for importers, exporters, and small logistics teams who need personalized guidance on freight operations, HTS code classification, landed cost modeling, or U.S. customs compliance strategy.

If you are interested in a direct consultation, please email tarsis.global@gmail.com with a brief description of your situation — your product category, trade lane, and the specific challenge you are trying to solve. I will review your inquiry and respond within 3 business days.

You can also use Tarsis AI — a free AI-powered logistics assistant available 24 hours a day, 7 days a week — for instant answers to freight forwarding and customs questions based on 15 years of real operational experience.
