Effervescent tablets contract manufacturing in India
Effervescent tablets need a low-humidity dry-room process, typically contract manufactured at an MOQ of 5,000–10,000 tubes, costing roughly ₹60–120 per 20-tablet tube ex-factory. First batch generally takes 8–14 weeks given the extra humidity-control validation this format needs, under an FSSAI licence.
Key facts
| Typical MOQ | 5,000–10,000 tubes of 20 tablets (around 400–800 kg of blend at 4 g per tablet, before losses) |
|---|---|
| Typical pack sizes | 10-tablet and 20-tablet tubes, strip or sachet variants |
| Indicative cost per unit | ₹60–120 per 20-tablet tube (ex-factory) |
| What the cost covers | Ex-factory: effervescent blend, compression, tube, foil or screw cap with desiccant, and label included; excludes GST, freight, shipper carton, brand margin |
| Lead time, brief to first batch | 8–14 weeks from brief and dry-room trial to first compressed batch |
| Key licences and certifications | FSSAI licence; product must comply with the FSS (Health Supplements, Nutraceuticals, Food for Special Dietary Use, Food for Special Medical Purpose, Functional Food and Novel Food) Regulations; Legal Metrology labelling for pre-packaged goods |
| Typical shelf life | 15–24 months, strongly dependent on packaging moisture barrier |
| Common formats | Effervescent tablet; dissolves in water before consumption |
How it is made
Formulation with acid-base system
Citric and/or tartaric acid is paired with sodium bicarbonate at a ratio tuned to give controlled fizzing without excess residue, alongside actives and flavour.
Dry-room granulation
Granulation is carried out in a humidity-controlled dry room, usually below 25% relative humidity, since any moisture triggers premature effervescent reaction.
Compression at low humidity
An effervescent-rated tablet press compresses granules into large-format tablets, with the press room held at the same low-humidity condition as granulation.
Tube filling with desiccant
Tablets are dropped into tubes along with a desiccant plug or cap insert and sealed immediately to block ambient moisture pickup.
Moisture and dissolution testing
A sample from each batch is checked for moisture content, dissolution/fizz time in water, and tube seal integrity before release.
What drives the cost
raises cost
Dry-room validation and running cost
Maintaining a low-humidity room through granulation and compression adds energy and validation cost compared with standard tablet lines.
raises cost
Tablet weight and acid-base load
A higher effervescent tablet weight (for stronger fizz or higher dose) uses more acid-base system per tablet, raising material cost.
raises cost
Tube and desiccant choice
A moisture-tight tube with an integrated desiccant cap costs more than a basic strip pack but protects shelf life in humid markets.
raises cost
Flavour and effervescent masking agents
Stronger flavour systems to offset the salty or metallic aftertaste of some mineral actives add formulation cost.
lowers cost
Batch size
Larger dry-room occupancy runs spread the fixed humidity-control cost across more tablets.
raises cost
Rework from humidity excursions
A humidity spike mid-run can spoil a partial batch; this risk is priced into smaller trial runs.
Common mistakes first-time brands make
Treating this as a standard tablet project
Brands who brief this like a normal tablet often underbudget for the dry-room requirement and are surprised by the cost difference.
Underestimating flavour masking needs
Mineral-heavy actives can leave a metallic aftertaste that needs a stronger flavour or sweetener system than a standard tablet would.
Choosing a tube without a desiccant feature
A plain screw-cap tube without a desiccant insert can let tablets absorb moisture and start fizzing inside the sealed tube.
Skipping accelerated stability testing
Without stability data under humid storage conditions, shelf-life claims for this format can prove optimistic in the field.
Choosing a manufacturer for effervescent tablets
Dry-room capability
Confirm the manufacturer runs a dedicated humidity-controlled room for effervescent granulation and compression, not a general tablet line.
Certifications
FSSAI licence is the baseline, with GMP certification showing documented humidity and batch-record control for this moisture-sensitive format.
Capacity fit
Check their effervescent-rated press and dry-room occupancy against your 5,000–10,000 tube MOQ.
Sampling under real storage conditions
Ask for a sample tube stored for a few weeks at ambient humidity to check it hasn't picked up moisture before full commitment.
Frequently asked questions
- Why do effervescent tablets cost more than regular tablets?
- They need a dedicated low-humidity dry room for granulation and compression, plus moisture-protective tube packaging, both of which add fixed and per-unit cost.
- What is the MOQ for effervescent tablets?
- Most manufacturers set MOQ at 5,000–10,000 tubes, partly because dry-room occupancy makes very small runs inefficient.
- How long does an effervescent tablet batch take?
- Allow 8–14 weeks: extra time goes into the acid-base ratio trial and humidity-controlled compression setup before the commercial batch.
- Does effervescent format need a different licence?
- No, the same FSSAI food supplement licence applies; the difference is in process control, not licensing.
- Can effervescent tablets be made without added sugar?
- Yes, with a sugar-free sweetener and flavour system, though the fizz profile and aftertaste masking may need extra formulation trials.
How BrandForge helps
BrandForge screens for manufacturers with an actual validated dry room and effervescent-rated press, not just a general tablet line, before matching your brief double-blind. A success manager tracks the humidity validation and stability sample through to your first sealed-tube batch.
