Frequently Asked Questions about Ammonium Bifluoride

What forms of ammonium bifluoride do you supply?

ABF is offered as free-flowing fine powder (D50 50–100 µm), flake (mm-scale platelets), and pre-dissolved 30% aqueous solution. The flake form is preferred for oilfield acidising; the powder for laboratory and electronics use.

Is ammonium bifluoride suitable for oilfield well-stimulation acidising?

Yes. Our oilfield-grade ABF is supplied in 25 kg moisture-resistant bags, with assay 98.5% min, free fluoride 32% min, water-insoluble matter < 0.05%, and chloride < 0.05%. Bulk shipments to drilling-services contractors include certified UN-1727 packaging.

What is the transport class for ammonium bifluoride?

ABF is regulated under UN 1727 (solid) and UN 2817 (solution), Class 8 (corrosive), Packing Group II. We ship with full IMDG / DGR / ADR documentation and UN-certified packaging.

What is the standard packaging for Ammonium Bifluoride?

Ammonium Bifluoride 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.

Product Reference Data

Chemistry & Physical Properties

Ammonium hydrogen fluoride, formula NH4HF2 (or NH4F·HF), formula weight 57.04 g/mol. White crystalline flakes or prills with characteristic ammoniacal odour. Melting point 126°C. Density 1.50 g/cm3. Highly water-soluble (~63 g/100mL at 20°C). Aqueous solutions are strongly acidic (pH ~3.5 at 1% solution) and release HF on contact with stronger acids.

Standards & Specifications

Industrial grades conform to generic supplier specifications and IS 9966-2 for inorganic fluorides. Glass-etching grade typically targets 98%+ assay with controlled chloride content (< 0.1%). USP and EP grades are not commonly specified for this compound. Reference standards include ASTM C1191 for industrial fluorides.

Regulatory & Transport Profile

CAS 1341-49-7. UN 1727 — Class 8 (Corrosive), PG II. GHS pictograms: GHS05 (corrosive), GHS06 (toxic), GHS09 (environmental hazard). REACH registered (EC 215-676-7). TSCA listed. Special transport rules: SAFEX/IATA/IMDG require HF-rated PPE and calcium gluconate first-aid availability.

Product Information & Resources

Frequently Asked Questions

How does it compare to HF acid for glass etching?
NH4HF2 is the preferred form because it is a free-flowing solid rather than a liquid acid — safer to handle, store, and dose precisely.
Does it release HF on storage?
Sealed containers in cool, dry conditions are stable for 24+ months. Moisture ingress will cause slow HF release — keep packaging tight.
Available in flake or powder?
Both — flake (5-15mm) for free-flowing dosing, powder for dissolution applications, and prills for automated handling.
What MOQ applies?
25 kg minimum for stock items. Sample lots of 100-500g available for technical evaluation.
