Frequently Asked Questions about Potassium Fluoborate

What grade of potassium fluoborate is required for abrasive grinding wheels?

Abrasives-grade KBF₄ is supplied at 98% min KBF₄, water-insoluble matter < 0.5%, free fluoride < 0.1%, particle size D50 ≈ 5–10 µm (fine, free-flowing). Each batch ships with a particle-size distribution and bulk density report.

Can KBF₄ be used as an Al-Ti-B grain refiner?

Yes. Our aluminium-grade KBF₄ is used together with K₂TiF₆ in the manufacture of Al-Ti-B master alloys for foundry grain refinement. Both feedstocks are sized to controlled particle distributions for in-melt dissolution efficiency.

What is the standard packaging for Potassium Fluoborate?

Potassium Fluoborate is supplied in HDPE woven bags with inner LDPE liner (25 kg / 50 kg net), HDPE drums (25 / 50 / 250 kg), and FIBC jumbo bags (500 / 1000 kg) for solid grades. Liquid grades ship in HDPE-lined steel drums (250 kg) or 1000 L IBC totes. Custom packaging — including nitrogen-blanketed, moisture-tight, or food-grade containers — is available on request.

What is the minimum order quantity (MOQ) and typical lead time?

Standard MOQ is 1 metric tonne for solid grades and 200 kg for liquid grades; pilot quantities of 5–25 kg are available for R&D qualification. Stock items dispatch within 7–10 working days from confirmed PO. Made-to-order grades and large export consignments require 3–4 weeks. Indian deliveries by road typically reach 4–7 days; export FCL shipments depend on destination port.

Do you provide MSDS / SDS and a Certificate of Analysis (COA)?

Yes. A 16-section GHS-format SDS is dispatched with every shipment and is also available in advance from marketing@sbfluorochem.com. A batch-specific COA accompanies every consignment and is emailed before dispatch for goods-receipt verification. Test methods follow IS / ASTM / USP / IP / EP as applicable.

Which countries do you export to and what Incoterms do you offer?

SB Chemicals exports to over 35 countries across South-East Asia, the Middle East, Africa, Europe, and the Americas. We hold IEC, GST, and APEDA registrations. Shipments move CIF / FOB / CFR / FCA / EXW from Mundra, Nhava Sheva (JNPT), or Hazira ports. Letter of Credit (LC), TT, and DA terms are accepted subject to credit approval.

Are your products manufactured to ISO 9001:2015 quality standards?

Yes. SB Chemicals operates an ISO 9001:2015 certified Quality Management System at the GIDC Vapi facility. Every batch undergoes raw-material testing, in-process control, and final QC release before despatch. Clients are welcome to schedule a third-party audit of the plant.
