Sodium Bicarbonate Price — Technical Grade Supplier

Q: What is the difference between sodium bicarbonate and soda ash?

Sodium bicarbonate (NaHCO3) is a mild alkali — around pH 8.3 at one per cent — and acts as a buffer. Soda ash (Na2CO3) is far stronger, around pH 11.5 at the same strength. Bicarbonate is chosen where pH has to be raised without overshooting; soda ash where alkalinity per rupee is what matters.

Q: What is the HSN code for sodium bicarbonate?

The HSN code for sodium bicarbonate is 2836 30 00 (Sodium hydrogencarbonate (sodium bicarbonate)). Grade does not change the code — technical, food and feed grade sodium bicarbonate all sit on the same line.

What we supply

Sodium Bicarbonate in bulk, against a written specification.

Sodium bicarbonate is the mild alkali of the soda family. A solution sits around pH 8.3 almost regardless of strength, against roughly pH 11.5 for soda ash, and that ceiling is why plants choose it: it lifts pH without the risk of overshooting into caustic territory. The number is not buffering in the textbook sense — bicarbonate is amphiprotic, so the pH settles near the mean of its two dissociation constants, about ½(6.35 + 10.33). The ceiling does assume the dissolved carbon dioxide stays in the water: a solution left standing, heated or hard aerated drifts towards carbonate and climbs past 8.3, which is exactly what happens in an aerated ETP basin.

It is a dry, free-flowing white powder that decomposes rather than melts. Heating drives off carbon dioxide and water and leaves soda ash behind — slowly from around 50 °C, faster as the temperature rises, and completely by about 270 °C. Two industries exploit that directly: bakers, who use the gas as a leavening agent, and flue-gas treatment plants, where bicarbonate injected into a hot duct — typically well above 150 °C — decomposes on the spot into a fine, highly reactive soda ash that scrubs sulphur dioxide and hydrogen chloride out of the stream. The same behaviour is why it must be stored dry and cool.

Grades & packing

What goes out, and how it is packed.

These are the formats we most commonly supply. Other grades, packing sizes and pack marking are available — ask at the enquiry stage.

Product	Formula	Grade	HSN	Packing
Sodium Bicarbonate	NaHCO₃	Technical grade	2836 30 00	25 / 50 kg bag

No tested values are published here. The certificate of analysis for the batch actually loaded travels with the despatch documents, and a representative COA and the safety data sheet go out before any commercial discussion.

Applications

Where sodium bicarbonate earns its place.

Flue-gas treatment

Dry sorbent injection to remove SO₂ and HCl from incinerator, boiler and furnace gases.

Effluent & process pH

Buffered pH correction in effluent plants, dye houses and process water, where overshoot has to be avoided.

Food, feed & pharma

Leavening agent, rumen buffer and pharmacopoeial uses exist, but these are licensed trades in India and we quote them only as set out below.

Leather & textiles

Deliming and neutralising in tanneries; neutralising after acid treatment in textile processing.

Fire & cleaning

Dry-powder extinguisher media and mildly abrasive cleaning and blasting media.

Handling & storage

What to get right before the load arrives.

Worth reading before you order rather than after. If any of this is a problem at your site, tell us — it usually changes what we would quote.

Site notes

Store in a cool, dry, covered store, away from acids and away from heat. Sodium bicarbonate picks up moisture and cakes in Indian monsoon humidity, and prolonged storage above about 50 °C will slowly convert it to soda ash. In practice moisture pickup and caking are what limit shelf life in Indian conditions, so rotate stock and keep bags sealed and off damp floors.
It is not classified as a dangerous good for transport and is not corrosive. There is no harmonised GHS classification, but producer safety data sheets in India do classify it — Tata Chemicals, for one, as Eye Irrit. 2B, H320 — so work from the safety data sheet for the lot you receive rather than from a blanket “not classified”. It is mildly alkaline in contact with moisture and no occupational exposure limit is assigned. Use dust extraction at tipping and bag-splitting points, side-shielded glasses and a dust mask.
It reacts with acids and releases carbon dioxide, sometimes vigorously. Do not add it to a closed or nearly full vessel of acid; add it slowly, with venting and stirring.
Carbon dioxide is heavier than air, so dosing bicarbonate into acidic effluent in a sump, pit or covered tank displaces oxygen at the bottom. Treat that as confined-space work: ventilate, gas-test before entry, and never lean into the opening. Keep it segregated from strong oxidisers as well as from acids.
Sodium bicarbonate is also traded in food, feed and pharmacopoeial grades, and those are separate regulated channels, not a different bag of the same thing. Food grade sits under the FSSAI regime, where the distributor is a food business operator in its own right and needs its own licence; IP-grade material is a drug substance and needs a wholesale drug licence (Form 20B/21B) from the state drug controller. We list technical grade here and will not quote a food or pharmacopoeial grade unless the licensing is in place at both ends. Tell us the end use at the enquiry stage.

Price

What actually moves the sodium bicarbonate price.

Sodium bicarbonate is priced off soda ash, since it is made from it, and moves with soda ash and carbon dioxide costs plus grade and packing. Food grade carries a premium over technical. We quote per kg or per MT in writing, landed at your delivery point, with a stated validity.

Questions

Sodium Bicarbonate — what buyers ask us.

What is the difference between sodium bicarbonate and soda ash?

Sodium bicarbonate (NaHCO₃) is a mild alkali — around pH 8.3 at one per cent — and acts as a buffer. Soda ash (Na₂CO₃) is far stronger, around pH 11.5 at the same strength. Bicarbonate is chosen where pH has to be raised without overshooting; soda ash where alkalinity per rupee is what matters.

Is sodium bicarbonate the same as baking soda?

Yes — baking soda is the common name for sodium bicarbonate. The difference that matters commercially is grade, not name: food-grade material is made and documented to a food specification, technical grade is not.

Do you supply food-grade sodium bicarbonate?

We list technical grade. Food grade in India sits under the FSSAI regime and pharmacopoeial (IP) material is a drug substance needing a wholesale drug licence, so we will not quote either unless the licensing is in place at both ends. Tell us the end use at the enquiry stage and we will say plainly what we can and cannot supply.

What is the sodium bicarbonate price per kg?

Sodium bicarbonate is quoted per kg or per MT, landed, and is priced off soda ash, so offers carry a stated validity. Food grade costs more than technical grade.

Are you a sodium bicarbonate manufacturer?

No — Velora is a bulk supplier and trader, not a manufacturer. Sodium bicarbonate is sourced from established Indian soda producers and supplied in 25 and 50 kg bags.

What is the HSN code for sodium bicarbonate?

The HSN code for sodium bicarbonate is 2836 30 00 (Sodium hydrogencarbonate (sodium bicarbonate)). Grade does not change the code — technical, food and feed grade sodium bicarbonate all sit on the same line. Source: the Indian customs tariff as listed in the GST HSN directory, checked September 2026.

Documentation

Sodium Bicarbonate — MSDS, COA and what travels with the load.

Not classified as a dangerous good for transport, so no TREM card is required. The safety data sheet still applies.

We do not publish blank certificates to download. A certificate of analysis belongs to a batch, so a generic one tells you nothing about the material on your vehicle — and the safety data sheet is the producer’s document for the grade actually quoted. Ask and both are emailed, usually the same working day.
