Fuel buyers and brokers looking to secure EN590, JET A1, and D6 fuels in Houston face a market that demands speed, transparency, and clear documentation. With competitive pricing and ready stock available, understanding the process and requirements can help close deals faster and ensure smooth transactions. This guide breaks down key points to help buyers and brokers navigate fuel purchases efficiently, focusing on Houston’s Vopak-to-Vopak transfers and the importance of proper buyer credentials.

Understanding the Fuel Types and Pricing
EN590, JET A1, and D6 are common fuel products traded in Houston’s energy market. Each has distinct uses and pricing structures:
EN590 is a standard diesel fuel used widely in Europe and increasingly in the US market. The buy-side price is around $5 per unit.
JET A1 is aviation turbine fuel, essential for commercial and private aircraft, with a buy-side price near $1 per unit.
D6 is a type of ultra-low sulfur diesel used primarily in the US, priced at approximately $0.04 on the buy side.
These prices reflect competitive market conditions in Houston, where fuel is often transferred Vopak to Vopak, meaning from one Vopak terminal to another, ensuring secure and efficient logistics.
Why Vopak-to-Vopak Transfers Matter
Vopak terminals in Houston serve as critical hubs for fuel storage and transfer. Using Vopak-to-Vopak transfers offers several advantages:
Speed: Transfers between terminals within the same facility or network reduce delivery times.
Security: Vopak’s infrastructure ensures product integrity and reduces risk of contamination.
Cost Efficiency: Minimizing transport and handling fees helps maintain competitive pricing.
Buyers benefit from knowing their fuel is ready and available at Houston’s Vopak terminals, allowing for quick transaction closures.
The Role of LOI and KYC in Fuel Transactions
One of the most important steps in moving forward with fuel purchases is having the Letter of Intent (LOI) and Know Your Customer (KYC) documentation in place for the end buyer. Sellers and refineries require these documents before engaging in any deal discussions.
LOI signals the buyer’s serious intent to purchase and outlines basic terms.
KYC verifies the buyer’s identity and financial standing, ensuring compliance with regulations.
Without these documents, sellers will not answer questions or provide further information. This requirement protects all parties and speeds up the deal process by filtering serious buyers.
Working Directly with Sellers and Refineries
Dealing directly with sellers and refineries simplifies communication and reduces intermediaries. This approach has benefits:
Transparency: Direct contact means fewer misunderstandings.
Faster Negotiations: Sellers respond quicker when buyer credentials are verified.
Better Pricing: Eliminating middlemen can improve commission structures and final prices.
Refineries and sellers maintain strict policies requiring LOI and KYC from the end buyer. Brokers and buyers should prepare these documents early to avoid delays.

Tips for Closing Deals Faster
To move fuel deals forward efficiently, consider these practical tips:
Prepare LOI and KYC early: Have these documents ready before initiating contact.
Confirm product availability: Verify that EN590, JET A1, or D6 is ready at Houston Vopak terminals.
Understand pricing clearly: Know the buy-side prices ($5 for EN590, $1 for JET A1, $0.04 for D6) to negotiate effectively.
Communicate directly with sellers: Avoid unnecessary intermediaries to speed up responses.
Ensure good commissions: Brokers should clarify commission terms upfront to avoid surprises.
These steps help reduce back-and-forth and build trust among all parties.
Common Challenges and How to Avoid Them
Fuel transactions can face obstacles if documentation or communication is incomplete. Common issues include:
Missing LOI or KYC: Sellers will not proceed without these.
Unclear pricing expectations: Leads to stalled negotiations.
Logistics misunderstandings: Confusion about Vopak-to-Vopak transfers can delay delivery.
Avoid these by preparing documents, confirming pricing, and understanding terminal logistics before starting negotiations.
