In the world of international trade and increasingly complex supply chains, trust matters, but verification remains essential. From quantity and quality to compliance with agreed specifications, SGS helps turn contractual commitments into verified reality.

In a sector where every decision involves operational, financial or reputational risk, the independence and objectivity of verification are essential to protecting the interests of all parties involved.

In a contract, several thousand tonnes of diesel are a quantity and a list of parameters. In the real world, the same cargo may pass through a storage tank, rail wagons, pipelines, a terminal and a vessel before the transaction is completed. Between those two points, someone has to demonstrate that what is stated in the documents is also what actually reaches the buyer. Standards define what the product should be like. On their own, however, they do not establish what is inside a particular tank, how much product has been transferred or whether its properties have been preserved along the way.

This is where SGS comes in, acting as an independent third party between the participants in the transaction. “Quantity and quality are not separate objectives, but two inseparable components of the same commercial reality. Only when assessed together do they provide clients with the complete picture they need to make informed decisions,” says Silvia Pătrunjel, Special Services Manager & Business Process Improvement Lead at SGS Romania.

In practice, this may involve measuring the volume or weight of a cargo on shore and on board a vessel, taking samples, checking tank inventories or measuring quantities delivered through pipelines. SGS also carries out tank inspections before leasing or use, supervises ship-to-ship transfers and blending operations, and issues inspection reports that can be used under documentary letters of credit.

Measurement is therefore not merely a formality attached to the transaction. It can become part of the mechanism through which the cargo is accepted and paid for.

One product, several control points

An operation may begin in a refinery storage tank. The buyer wants to know whether the product it is about to purchase has the agreed characteristics. Samples are taken and the product is analysed.

The SGS laboratory in Negoiești, Prahova County, provides testing services for petroleum products including petrol, diesel and crude oil, analysing critical parameters such as density, distillation, flash point, water or sulphur content, as well as other indicators essential to the quality and compliance of petroleum products. According to the company, it is the only independent third-party laboratory in Romania accredited by RENAR under ISO 17025 for this type of testing.

If the cargo then travels by rail to Constanța, verification moves with it. The wagons may be weighed, the product may be sampled again, and further quantity and quality measurements are carried out when the vessel is loaded. SGS has teams in Romania’s main petroleum and port locations, including Constanța, Midia, Agigea, Brăila, Galați, Drobeta-Turnu Severin and Giurgiu.

Why are these checks necessary? Because the product is moving and conditions change. A wagon previously used to carry another cargo may create a contamination risk. The inspector needs to identify that risk before loading, not after the product has been compromised. Likewise, a laboratory result is relevant only if the sample being analysed accurately represents the product in the tank, wagon or vessel.

In the Oil, Gas & Chemicals sector, inspection is a preventive tool, not merely a way of documenting what has already happened. SGS specialists are present at critical points along the operational chain, where quantity discrepancies, changes in quality or situations with significant commercial consequences may arise.

Who do we trust?

There is another issue that neither standards nor automation can solve on their own: who produces the information that all parties are expected to trust?

A producer may analyse its cargo in its own laboratory. But if the product is sold to a trader and then to another buyer, every participant needs a result it can accept without relying exclusively on the assessment of the seller.

“AI and digitalisation are rapidly transforming the Oil, Gas & Chemicals industry, but the value SGS continues to provide remains the same: independent, objective and reliable information that allows the parties involved to make decisions based on verified facts,” says Daniel Nedelcu-Damiciuc, OGC Manager at SGS Romania.

SGS Romania’s inspection activities are accredited by RENAR under SR EN ISO 17020, while the company says its field personnel work according to internationally recognised standards and practices for hydrocarbon measurement and sampling. “Through its technical expertise and global presence, SGS helps manage commercial and operational risks by providing independent information on the quantity, quality and compliance of petroleum products throughout the Oil & Gas supply chain, from production and storage to custody transfer and final delivery,” concludes Silvia Pătrunjel.

Products are becoming increasingly standardised and information is moving ever faster. In a world where data is available instantly, the independent inspector remains the essential link between documents and reality. The figures and the contract describe the transaction, but trust is built when someone confirms that what happens on the ground matches the commitments that have been made.
