About Delttex Traders - Mineral Products Supplier in Pakistan

Delttex Traders operates from Pakistan and currently lists six distinct mineral products in its catalogue. The product set includes construction sands, silica sand, land reclamation sand, granite aggregates, drilling‑grade barite lumps, and bentonite clay. These items are grouped under the categories Sandstones & Sands, Silica Sand, Aggregates, Other Ores & Minerals, and Clay as indicated in the supplier data. The catalogue references HS code families 2505, 2517, 2511 and 2508, which correspond to silica sand, granite aggregates, barite and bentonite respectively. The supplier’s active product count of six reflects a focused portfolio of bulk mineral commodities.

Product Range and Specialties of Delttex Traders

The listed construction sands and land reclamation sand are bulk silica‑based materials typically graded for particle size distribution between 0.1 mm and 2 mm, with moisture content below 0.5 % for optimal compaction. Silica sand (HS 2505.10) is described as high‑purity with 99 % SiO₂, a grade commonly required for glass manufacturing, silicon metal production and semiconductor substrates, where grain fineness and low iron content are critical. Granite aggregates (HS 2517.10) are crushed natural igneous rock with a felsic composition, usually supplied in 20 ft or 40 ft containers as 25 mm to 40 mm crushed stone for concrete, road base and railway ballast applications. Drilling‑grade barite lumps (HS 2511.00) are natural barium sulfate, typically meeting a specific gravity of 4.2 or higher and used as weighting material in oil‑field drilling fluids; standard specifications call for low impurity levels and particle size under 4 mm. Bentonite clay (HS 2508.10) is natural montmorillonite, often supplied as sodium‑activated or calcium‑activated forms with swelling indices above 15 % and moisture contents around 12 %, suitable for drilling mud, foundry sand binders and landfill liners.

Trade and Export Information - Delttex Traders

Pakistan’s mineral sector exports silica sand, aggregates, barite and bentonite primarily to the Middle East, South‑East Asia, Africa and parts of Europe, where construction, glass production and oil‑field services generate steady demand. HS chapter 25 covers the listed products, and buyers usually request compliance with ASTM C144 (silica sand), ASTM D422 (aggregate grading), API BP 2 (barite) and ISO 14688 (bentonite) standards. Common certifications include ISO 9001 quality management, SGS inspection reports and, where required, CE marking for EU markets. Shipping is typically arranged on bulk cargo vessels or in 20 ft/40 ft containers, with FOB or CIF terms prevailing; moisture control and bulk bag sealing are standard packaging practices to preserve material integrity during transit. Pakistani exporters benefit from established mining licenses and government‑approved export procedures that facilitate customs clearance under the mentioned HS codes.

Sourcing from Delttex Traders - Buyer Guidance

When sourcing silica sand from Delttex Traders, request a recent material test report showing SiO₂ content, grain size distribution, loss on ignition and iron impurity levels; these parameters verify the 99 % purity claim. For granite aggregates, ask for a particle size analysis, crushing strength test (MPa) and bulk density data to confirm suitability for concrete or road base specifications. Barite purchases should be accompanied by a certificate of analysis indicating specific gravity (≥ 4.2), BaSO₄ purity and moisture content, as well as an SGS inspection certificate. Bentonite orders require a swelling index test, cation exchange capacity and moisture content report, together with confirmation of sodium or calcium activation. Verify that the supplier can provide the relevant HS codes on commercial invoices and that packaging meets bulk bag or container standards before confirming the order.

What purity level does the silica sand from Delttex Traders have?

The catalogue specifies high‑purity silica sand with 99 % SiO₂ content, which aligns with typical glass‑making requirements. Buyers usually request an SGS‑issued material test report to confirm the exact purity and impurity profile.

Which HS code applies to the granite aggregates?

Granite aggregates are listed under HS code 2517.10, covering crushed natural igneous rock. This code is used for customs documentation and aligns with standard aggregate export classifications.

What is the typical specific gravity for the barite lumps offered?

The product is described as drilling‑grade barite with a specific gravity of 4.2, a common benchmark for weighting agents in drilling fluids. A certificate of analysis should confirm the exact specific gravity before shipment.

Can I obtain a sample of the bentonite clay before placing a large order?

Yes, suppliers of bentonite typically provide a small bulk‑bag sample (1‑5 tonnes) for testing swelling index and moisture content. Request a sample together with the material test report to verify compliance with your project specifications.

What packaging formats are used for the construction sands?

Construction sands are generally shipped in bulk bags (1 tonne each) or directly loaded into 20 ft/40 ft containers for larger volumes. The packaging is designed to limit moisture ingress and allow easy unloading at the destination site.

Which certifications should I ask Delttex Traders to provide for mineral exports?

Buyers should request ISO 9001 quality management certification, an SGS inspection report, and any ASTM or API test reports relevant to the specific mineral (e.g., ASTM C144 for silica sand, API BP 2 for barite). These documents verify that the product meets internationally recognised standards.
