Quality & sampling methodology
Sampled at source. Sealed. Lab-tested.
LTC's quality assurance begins at the loading point, not on arrival. Every consignment is witnessed and sampled during loading by Mitra S. K. Private Limited (MSK) — a Kolkata-headquartered, accredited testing, inspection and certification agency whose mineral and metal certificates are recognised across the industry.
Increments are drawn day-wise as the truck is loaded, combined into a representative composite, and prepared for analysis. Samples are jointly sealed with numbered tamper seals and retained, so results can always be traced back to sealed material.
Each composite is tested for Moisture, Total Iron [Fe(T)] and Metallic Iron [Fe(M)] at the laboratory, and the result is read against the buyer's acceptance specification before the material is cleared for dispatch.
This gives both supplier and buyer a single, independent record of what actually shipped — the foundation of a clean LC presentation and a dispute-free delivery.
A full truck sampled, live, during loading
On the first loading, LTC's appointed inspector witnessed the sampling of a complete truck — 70 MT — drawn during loading. Increments were collected in three progressive rounds as the vehicle filled, then combined into a single composite sample in line with IS 15774.
Witness & collect
Increments drawn day-wise during truck loading, under inspector supervision.
Composite & prepare
Increments combined and reduced to a representative composite sample per IS 15774.
Seal & retain
Samples jointly sealed with numbered tamper seals and retained for reference.
Analyse & report
Moisture, Fe(T) and Fe(M) determined at the lab; result read against buyer spec.
Sampling and analysis carried out by MSK. Inspection findings reflect the material at the time and place of sampling and support, but do not replace, the commercial terms agreed between buyer and seller.
