What buyers ask us about soda ash.
Should I order dense or light soda ash?
Glass plants use dense (higher bulk density, less dusting in batch handling). Detergent, textile and water treatment typically use light. If you are replacing another supplier, match their bulk density spec — send it to us and we will confirm the grade.
What iron level do you guarantee for glass applications?
Fe₂O₃ ≤ 0.004% (40 ppm) per the standard specification; tighter iron on request for low-iron glass — ask with your target and we will quote against current production lots.
Can you handle large recurring volumes?
Yes — monthly recurring FCL programs are our core business. Recurring buyers get production scheduling priority and a fixed documentation format for faster clearance.
Is there a trade investigation affecting soda ash imports into India?
Yes. India's DGTR initiated a safeguard investigation into soda ash imports in March 2026 (notified to the WTO in April 2026), assessing whether import volumes justify quantitative restrictions or duties. This is separate from the existing minimum import price mechanism. If you import into India, ask us for the current status before committing to a shipment schedule — we track this and will flag any change that affects your landed cost.
