Calcium Chloride CaCl₂

We do not publish prices. Calcium chloride is quoted per consignment because the landed cost depends on which grade you take, and the grades are not comparable per tonne: a tonne of 94–97% anhydrous carries about 1.22 to 1.31 times the contained CaCl₂ of a tonne of 74–77% flake (1.22 comparing 94% against 77%, 1.31 comparing 97% against 74%), and a tonne of 32–35% solution is mostly water. Quotations also move with the production route, with origin — China is the largest exporter, so Chinese offers, sea freight and the rupee set the ceiling on imported material — and with packing, volume, credit terms and delivery point. Send us the grade, the quantity, the packing and the delivery location and you will get a landed price against the producer’s COA.

No. It has no UN number, class or packing group in any form or concentration, under the UN Model Regulations, ADR/RID, IMDG, ICAO/IATA or DOT. The GHS label (Eye Irrit. 2, H319) still applies to the package. If you are shipping in bulk rather than bagged, check the IMSBC Code position for your voyage — we have not confirmed a schedule either way. And do not let anyone in your freight chain read “chloride” as “chlorate”: calcium chlorate is a Class 5.1 oxidiser, UN 1452 or UN 2429, and is a different product entirely.

In practice, no — not because it is banned, but because the dose that works does not fit inside the chloride budget. IS 456:2000 clause 8.2.5.2 and Table 7 cap total acid-soluble chloride in the concrete, from every source — cement, aggregate, water and admixture — at 0.6 kg of Cl per m³ for reinforced concrete and concrete containing embedded metal, 0.4 kg/m³ for prestressed and for steam-cured concrete, and 3.0 kg/m³ where there is no embedded metal. Note the unit: IS 456 works in kg per m³ of concrete, not per cent by mass of cement, which is where pages copying ACI or BS figures go wrong. Working it through at a cement content of 350 kg/m³, the 0.6 kg/m³ ceiling is about 0.17% Cl by mass of cement; anhydrous CaCl₂ is 63.9% chloride, so the entire chloride budget — before counting the chloride already in the cement, sand, aggregate and water — is about 0.94 kg of CaCl₂ per m³, roughly 0.27% by mass of cement. The dose usually quoted for acceleration is 0.5–2% by mass of cement. That arithmetic is ours, and the cement content assumed is stated, but the conclusion is not marginal: it exceeds the limit at the bottom of the accelerator range and grossly exceeds it at the top. For prestressed concrete the limit is stricter still and chloride accelerators are not used, for the well-established reason that chloride causes stress-corrosion cracking of high-tensile prestressing steel. IS 456 never names calcium chloride at all; the codes to read for a prestressed or admixture decision are IS 1343 (prestressed concrete) and IS 9103 (admixtures), neither of which we have been able to obtain, so this answer rests on IS 456’s chloride ceiling and on the mechanism rather than on a clause in either. IS 456 also requires the chloride content of an admixture to be tested independently for each batch before acceptance, and trial mixes to establish strength and slump loss. Where calcium chloride is still used in concrete work it is in unreinforced concrete, and even then it attacks the paste itself: it reacts with hardened cement to form calcium oxychloride, an expansive phase that causes spalling and scaling around joints. Take a structural engineer’s decision on this, not a supplier’s.

Not at present. Calcium chloride is a permitted food additive in India — FSSAI’s Appendix A allows it in thermally processed fruits and vegetables at up to 350 ppm, in candied and crystallised fruit and murabba at GMP level, and in cheese at up to 200 mg/kg of milk; internationally it is INS 509, a firming agent, and JECFA sets no numerical ADI. But selling material for food use makes the seller a food business operator under the Food Safety and Standards Act, needing its own FSSAI registration or State or Central licence on the turnover thresholds. Our calcium chloride is offered as technical grade only. Two things worth knowing if you are a food buyer: food-grade material is normally specified to FCC/USP or Codex rather than to IS 1314, and calcium chloride is not among the additives named for paneer or chhana in FSSAI’s dairy chapter, whatever it is permitted in for cheese.

No. Pharmacopoeial-grade material is a different regulatory question from technical grade — wholesale dealing in drugs in India is licensed under the Drugs and Cosmetics Rules 1945, in Form 20B and, for Schedule C and C(1) products such as injectables, Form 21B, with a registered pharmacist or qualified competent person on the premises. We supply technical grade and do not offer pharmacopoeial grades.

Calcium chloride is not a specified fertiliser under the Fertiliser (Control) Order 1985 — it is not in Schedule I Part A, and the 2022–23 FCO amendments that added several new products did not add it. So it may not be sold or labelled as a fertiliser in India, and no FCO dealer registration covers it. We supply it as an industrial chemical. Growers who use it as a calcium source are working outside the FCO framework, and we do not make agronomic claims or give dosage recommendations for it.

Not in the acid or caustic sense — there is no free alkali, and it is not classified for skin corrosion. But it is a concentrated chloride brine, and that is a different and more expensive problem. It causes chloride stress corrosion cracking of 304 and 316 stainless steel from as low as 38 °C, worse in wet-and-dry service where evaporation concentrates chloride locally; it drives corrosion of steel reinforcement in concrete; and it forms expansive calcium oxychloride in hardened cement paste. Store brine in epoxy-lined carbon steel, or in FRP or HDPE for smaller tanks at near-ambient temperature — not in ordinary stainless, and not in galvanised equipment.

Not a single number, and any supplier quoting one is inviting a rejected consignment. IS 1314:1984 specified the pH of a 5% solution at 25 °C as 7.0–8.5 for the technical types. That is the kind of figure a buyer holds a supplier to — but note the edition: IS 1314 was superseded by IS 1314:2024 and we have not been able to read the 2024 requirement tables, so treat 7.0–8.5 as the 1984 limit and agree the pH window against the current edition and the lot COA. A dilute solution of pure calcium chloride is essentially neutral to slightly acidic (about pH 6.0–6.5 at 0.1 mol/L); concentrated commercial liquor typically reads alkaline, around 8–10, because the process route often leaves residual lime-derived alkalinity — and pH measurement is unreliable anyway at the ionic strength of a 35% brine. Tell us the pH window your process needs and we will quote against the COA.

Work back from what you need it for. For brine make-up and dust suppression, buy on contained CaCl₂ landed, which often means anhydrous inland and solution near the source. For drying duty, the anhydrous grade is the one — IS 1314 Type B is defined as the drying agent. For refrigeration brine, flake dissolves with a far gentler exotherm than anhydrous, which matters if you are mixing by hand. And if the material is going into anything where the impurity profile matters more than the assay, tell us the application so the production route can be specified.

No — Velora is a bulk supplier and trader, not a manufacturer. We source from producers and supply against the producing plant’s certificate of analysis for each lot, with the SDS and, on request, the TDS.

No. Velora supplies bulk only — 25 kg bags upwards, jumbo bags and drums, with tanker supply on enquiry — and does not supply retail packs or laboratory reagents.

The HSN code for calcium chloride is 2827 20 00 (Calcium chloride). Heading 2827 covers chlorides; 2827.20 is calcium chloride, an 8-digit ITC(HS) line with no Indian sub-split. Anhydrous, dihydrate, flake, prill, granule, powder and 32–35% solution all share the code — Chapter 28 Note 1(a) covers separate chemically defined compounds “whether or not containing impurities”, Note 1(b) covers them “dissolved in water”, and physical form is not a classification criterion anywhere in the heading. An anti-caking or anti-dusting additive does not move it either. Two things worth knowing that are not the code: there is no 10 kg pack rule here (unlike potassium chloride and ammonium sulphate, where packs ≤10 kg gross move to 3105 10 00). The pack-size rule that does exist is Chapter 98 heading 9802 00 00, laboratory chemicals, which catches chemicals imported in packs of 500 g or 500 ml or less that are identifiable as lab reagents. Note 3 to Chapter 98 was amended in September 2024 to require that such imports be for the importer’s own use, “other than purposes like trading, further sale etc.” Velora supplies bulk only and no lab or reagent packs, so 9802 does not arise. GST rate is not published here. The rate shown in commercial HSN databases could not be verified against the CBIC rate notification (cbic.gov.in was unreachable), and site policy is to publish no GST rates. Treat this as information, not tax advice: confirm the code and the applicable GST rate with your tax adviser and cross-check the code against your own purchase invoices.
