Pre-shipment Inspection

Pre-shipment inspection is offered to exporters and importers and comprises a detailed inspection of equipment or materials after manufacture, but prior to shipment. Scope can include Quality & Quality, Packing & Marking and Supervision of Loading. A Certificate of Inspection can be provided against a Letter of Credit and authorized by a Chamber of Commerce.
We also offer a host of specifically developed sampling techniques to ensure an accurate representation of the cargo is taken. Our skilled staff can oversee the drawing of these samples, or take them manually if required.

Testing Services

SPECTRO recently invested in a state-of-art metals & minerals testing laboratory. At SPECTRO we know that time equals money. That is why we are proud of our industry leading turnaround times. Through our network of specific minerals and metals testing laboratories we can provide an independent determination of quality when you need it.

  • Metals and minerals - Using Inductively Coupled Plasma - MS (ICP-MS)
  • Classical wet bench chemistry as well as technologically advanced instrument determination
  • Verification of material condition and segregation
  • Representative testing of samples
  • Moisture determination

Coal Sampling and Analysis

SPECTRO has established its own coal testing laboratories at many locations in India and also in Indonesia. It has plans to setup more labs at places like Dubai, Muscat, South Africa etc.

Superintending Services

SPECTRO can now deliver accurate, timely and reliable superintending services with integrity to the coal trading community. Through our experienced surveyors and technicians, we can help to minimize losses and maintain quality at various stages of the coal production process, its transportation at origin and destination.

Quantity Determination
  • weight/volume of coal at stockpile by using a theodolit
  • weight of coal for loading/discharging to/from barge and/or vessel determined by draught survey method as per the United Nations Economic Commission (UNEC / ESC) standard

SPECTRO Coal Laboratory can analyze and certify quality of coal originating from pre-shipment and/or stock pile before loading. We also offer quality certification services for coal sampled during loading and discharging.

Stockpile Measurement Services by Laser Survey

SPECTRO can measure and quantify dry bulk inventory stockpiles, such as coal and petroleum coke, using advanced laser surveying technology. Laser surveying provides faster stockpile measurement times, better accuracy, and real time results. This laser survey accurately determines the volume of an irregularly-faced stockpile, without the necessity of complete stockpile grooming. In fact, minimal stockpile grooming is ideal for best results.
Inspection reports include 3D images of the stockpile, and can be quickly produced.
Laser surveying experts measure bulk inventory stockpiles, including coal, minerals, petroleum-coke, agricultural products and dry bulk chemicals.

Petroleum Coke and Fly Ash Testing
