Who we are

Founded in the United States, Tzero Labs is an independent petroleum testing coordination and field inspection support company dedicated to the oil, gas, and energy value chain. We support refineries, buyers, sellers, tank farms, shipping companies, storage operators, and trading companies with dip test coordination, cargo inspection support, laboratory testing coordination, quality and quantity verification, and documentation services across major global oil and gas ports.

Our operating model is straightforward: clear communication, coordinated action, and strict attention to safety. Whether you are arranging a dip test, verifying a cargo of EN590 diesel, coordinating Jet A-1 inspection, or supporting a marine fuel transaction, we connect the right inspection agencies, testing procedures, and documentation processes to deliver credible, defensible results — on time.

What makes us different
  • All testing coordinated through ISO/IEC 17025 accredited agencies — SGS, Intertek, Bureau Veritas, Cotecna, and Saybolt — so every result carries recognized, commercially defensible credentials.
  • End-to-end documentation management — from inspection instructions and sampling coordination to final certificate delivery and complete transaction records.
  • Coordination reach across major petroleum ports, tank farms, terminals, and marine facilities — supporting dip tests, cargo inspection, and laboratory testing where your product is.
  • ESG integration: responsible field operations, ethical supplier engagement, and governance standards applied to every petroleum engagement.
Our Work

How We Deliver

Our work is built around accuracy, speed, transparency, and trust. In petroleum transactions, every delay in testing, sampling, tank access, or laboratory reporting can affect vessel loading, product transfer, payment release, and overall transaction confidence. Tzero Labs helps prevent these delays by coordinating the right inspection process, the right testing body, and the right documentation flow from the beginning.

We work with recognized international inspection and laboratory companies such as SGS, Intertek, Bureau Veritas, Cotecna, Saybolt, and other approved port-based testing agencies to help ensure that product testing and certification are completed professionally and without unnecessary delay.

Our operating model is simple: clear communication, disciplined testing procedures, strong field coordination, and strict attention to safety. Whether the requirement involves EN590 diesel, Jet A-1, D6 fuel oil, crude oil, marine fuel, renewable diesel, petrochemicals, or other refined petroleum products, we help align the correct methods, inspectors, equipment, and laboratory process to deliver dependable results.

"From dip test scheduling and tank access coordination to product sampling, quality and quantity verification, laboratory reporting, and inspection documentation, Tzero Labs helps clients make faster and more confident commercial decisions."
