6 Things to Check Before Choosing a Syrup Manufacturer in India

With over 500 WHO-GMP certified pharmaceutical facilities in India (CDSCO, 2024-25), India supplies over 60% of global UNICEF-procured pharmaceutical requirements by volume (UNICEF Supply Division, 2023) — much of it oral liquid formulations. Six specific checks, including a format decision most buyers get wrong, determine whether your syrup supply chain survives shipping to a tropical climate market.

About 9M India Limited — examples and standards referenced in this guide

9M India Limited is a WHO-GMP certified pharmaceutical manufacturer established in 2009, located in Birkoni, District Mahasamund, Chhattisgarh. The company holds DCGI-approved manufacturing licences for 200+ molecules across dry syrups, ready-to-use syrups, and oral suspensions, including anti-malarial and paediatric antibiotic formulations. This guide uses 9M India’s documentation standards as the benchmark — COPP, FSC, COA, and stability data available within 24 hours, exports to 15+ countries.

Why these 6 checks matter — industry context

India supplies over 60% of global UNICEF-procured pharmaceutical requirements by volume (UNICEF Supply Division procurement records, 2023), with paediatric antibiotic dry syrups and anti-malarial suspensions among the most volume-significant exports to Sub-Saharan Africa. A verification challenge specific to syrups: dry syrup and ready-to-use (RTU) formats require entirely separate stability data — powder before reconstitution, and suspension after — and many buyers don’t realise both are needed until a registration query reveals the gap. These six checks are the practical buyer’s verification framework, drawn from the documentation requirements of NAFDAC (Nigeria), TFDA (Tanzania), NDA (Uganda), and WHO prequalification guidelines.

Format Selection

Confirm dry syrup vs RTU format capability for your export market

The format decision made at the enquiry stage determines your cold-chain requirements for the entire supply chain.

#1 of 6

Dry syrups (powder for oral suspension) require no cold chain before reconstitution and are strongly preferred for Africa and South-East Asia — lighter to ship, longer shelf life, lower heat-degradation risk. Ready-to-use (RTU) syrups are pre-mixed liquid, requiring specific storage temperature management during shipping. Not every syrup manufacturer in India produces both formats.

Why format choice is a supply-chain decision, not a formulation preference
For antibiotic syrups exported to Sub-Saharan Africa specifically, dry syrup format is standard and often expected by buyers and regulatory authorities alike. Confirm the manufacturer’s actual production capability for your specific format before finalising any formulation discussion.

How to verify - step by step

  • State your target market and cold-chain reality upfront: This determines which format is realistic for your supply chain.

  • Confirm the manufacturer produces your required format: Not every syrup manufacturer offers both dry syrup and RTU.

  • Ask about reconstitution instructions and diluent: Confirm these meet your target market’s labelling requirements.

  • Check shipping weight and packaging implications: Dry syrup’s weight advantage affects freight costs meaningfully at scale

Format Cold Chain Needed Best Suited For
Dry Syrup (powder) No — until reconstitution Africa, South-East Asia, remote supply chains
RTU (ready-to-use) Yes — temperature-managed shipping Markets with reliable cold chain infrastructure

 

Why this check matters for export

Procurement agencies and regulatory authorities in Sub-Saharan Africa frequently specify dry syrup format explicitly in tender and registration requirements — offering RTU when dry syrup was required is a common cause of disqualification.

Red flags to watch for

Manufacturer offers RTU when dry syrup was specifically requested · No clarity on reconstitution stability period after mixing · Cannot confirm format capability without a formal quote request · Packaging doesn’t match stated format (e.g. liquid-appropriate bottle for a powder product)

WHO-GMP Certification

Verify the WHO-GMP certificate expiry date — not just the existence of a certificate

The most common buyer mistake is confirming a WHO-GMP certificate exists without checking whether it's currently valid.

#2 of 6

When sourcing from a syrup manufacturer in India, request the actual WHO-GMP certificate document. It must show the facility name, manufacturing site address, licence number, dosage forms covered, issue date, and expiry date. WHO-GMP certificates in India are issued by CDSCO following an on-site inspection.

What is WHO-GMP certification in India?
WHO-GMP is a pharmaceutical-specific manufacturing standard covering facility design, water systems, air handling, process validation, analytical QC, and batch documentation. It is time-limited and requires periodic re-inspection. It is distinct from ISO 9001, which is not accepted for pharmaceutical export drug registration.

How to verify — step by step

  • Request the actual document: Ask for a PDF or scan on official CDSCO letterhead.

  • Check the expiry date explicitly: Do not accept a certificate without a visible expiry date.

  • Confirm dosage forms covered: The certificate should list oral liquid manufacturing specifically.

  • Cross-verify on CDSCO database: Cross-reference at cdsco.gov.in using the licence number.

Why this check matters for export
NAFDAC, TFDA, and NDA all require submission of a valid, unexpired WHO-GMP certificate for drug registration. An expired certificate is grounds for automatic rejection. (WHO Technical Report Series No. 986, 2014)

Red flags to watch for

Certificate older than 3 years with no re-inspection documentation · Certificate does not list oral liquid dosage forms · Manufacturer cannot provide certificate within 24 hours · Certificate shows a different manufacturing site

DCGI Approval

Confirm DCGI approval at the molecule and dosage-form level

Syrup approval is separate from tablet or capsule approval for the identical molecule.

#3 of 6

The DCGI manufacturing licence for oral liquid products is separate from approvals held for the same molecule in tablet or capsule form. A manufacturer approved for Amoxicillin capsules is not automatically approved for Amoxicillin dry syrup.

Why this distinction matters for syrups specifically
Confirm the manufacturer holds DCGI approval specifically for the oral liquid form of your molecule, at your required strength and concentration (e.g. 125mg/5ml vs 250mg/5ml are distinct approvals).

How to verify — step by step

  • Request the manufacturing licence for the oral liquid form specifically: Not a tablet or capsule approval for the same molecule.

  • Confirm the exact concentration is listed: 125mg/5ml and 250mg/5ml require separate approvals.

  • Verify format-specific approval: Confirm the licence covers your required dry syrup or RTU format.

  • Cross-check against your target strength requirement: Ensure it matches exactly, not just the same molecule at a different concentration.

Why this check matters for export

Import regulators require the dossier to cite a dosage-form-specific manufacturing licence — a generic molecule approval without oral liquid specificity is a common cause of registration query.

Red flags to watch for

Manufacturer shows tablet/capsule approval when oral liquid approval was requested · Concentration on the licence doesn’t match your requirement · No clarity on format-specific (dry syrup vs RTU) approval · Licence shows a different manufacturing site

Stability Data

Request ICH Zone IVb stability data — for both unconstituted powder and reconstituted suspension

Dry syrups need two separate stability studies, not one — and most buyers only ask about the first.

#4 of 6

For export to Africa, the Middle East, and South Asia, stability data under ICH Zone IVb conditions (30°C/75% relative humidity) is required for drug registration. For dry syrups specifically, this means separate stability data for the dry powder before reconstitution and the suspension after reconstitution — these are genuinely different stability studies.

Why reconstituted stability data is the check most buyers skip
Powder stability confirms the product survives storage and shipping before use. Reconstituted stability confirms the mixed suspension remains effective and safe for the labelled in-use period (commonly 7–14 days after mixing, stored appropriately). A manufacturer without both studies has not fully validated the product for real-world use.

How to verify — step by step

  • Request Zone IVb data for the dry powder specifically: 30°C/75% RH, covering the full claimed shelf life before reconstitution.

  • Request separate reconstituted stability data: Covering the labelled in-use period after mixing

  • Confirm dose uniformity is included in reconstituted data: Especially critical for paediatric antibiotic and anti-malarial suspensions.

  • Check the reconstitution instructions match the stability conditions tested: Diluent type and volume should be identical to what’s on the label.

Why this check matters for export
Import regulators specifically request both unconstituted and reconstituted stability data as part of the Quality module of the dossier — providing only one is treated as an incomplete submission.

Red Flags to Watch For

Only unconstituted powder stability data offered · No reconstituted stability data available · Dose uniformity data missing from reconstituted stability study · Reconstitution instructions don’t match what was actually stability-tested

Certificate of Analysis

Request a sample Certificate of Analysis within 24 hours — and know what to look for

A genuine syrup manufacturer in India holds batch release data and can share a sample COA immediately.

#5 of 6

A Certificate of Analysis (COA) is the batch-level document proving a specific production batch meets all specifications. A legitimate syrup manufacturer generates a COA for every batch — a sample should be available within 24 hours.

What a complete syrup COA must contain
Beyond assay, syrup COAs require pH, viscosity, microbial limits, preservative content, and — critically for suspensions — dose uniformity data, since accurate dosing in a liquid suspension depends on the active ingredient being evenly distributed, not settled.

How to verify — step by step

  • Request a real sample COA: From an actual recent batch, not a template.

  • Confirm dose uniformity data is included for suspensions: This is the parameter most often omitted.

  • Check preservative content is tested, not assumed: Especially for multi-dose bottle formats.

  • Verify the signing authority: Should be signed by a Qualified Person or pharmacist.

Parameter Why It Matters
Assay (potency) Confirms active ingredient at label strength
pH Confirms stability and patient tolerability
Viscosity Confirms correct pour and dosing consistency
Microbial limits Confirms contamination within acceptable range
Preservative content Confirms multi-dose formulation efficacy
Dose uniformity (suspensions) Confirms accurate dosing — critical for paediatric use

Why this check matters for export
International regulators require actual numerical results — a COA missing dose uniformity data for a suspension product is treated as incomplete for paediatric drug registration submission.

Red Flags To Watch For

COA not available within 24 hours · Dose uniformity data missing for suspension products · COA is a blank template without real batch data · Preservative content not tested

Export References

Ask for export references in your specific target country — an existing COPP saves 6–12 months

If the syrup manufacturer has already registered products in your market, your registration timeline shrinks dramatically.

#6 of 6

A Certificate of Pharmaceutical Product (COPP) confirms a specific product is authorised for manufacture and sale in India. If a syrup manufacturer has already exported to your target country and holds an active COPP, your registration timeline can shorten by 6–12 months.

What is a COPP (Certificate of Pharmaceutical Product)?
A COPP is issued under the WHO Certification Scheme by CDSCO for products manufactured by a DCGI-licensed manufacturer at a WHO-GMP certified facility. For syrups, confirm the COPP references your exact format (dry syrup vs RTU) and concentration. (WHO Technical Report Series No. 986, Annex 10)

How to verify — step by step

  • Ask “Have you previously exported to [country]?” — request the specific product name and year of first registration.

  • Ask “Do you hold an active COPP for [country]?” — confirm it matches your exact molecule, format, and concentration.

  • Ask “Can you provide a CTD or ACTD dossier?” — export-experienced manufacturers typically hold ready dossiers.

  • Ask about NHM or UNICEF procurement experience if relevant: This signals stronger documentation discipline for institutional buyers.

Why this check matters for export
Dossier review queues in Africa are long; an existing, format-matched COPP eliminates the initial 30–90 day waiting period entirely — particularly valuable for time-sensitive paediatric and anti-malarial procurement programmes.

Red Flags To Watch For
Vague answers about prior export experience · COPP offered doesn’t match your specific format or concentration · No CTD/ACTD dossier despite claimed export history · Cannot name a specific country or product previously registered

Frequently asked questions

  • Why is dry syrup preferred over RTU syrup for African markets?

    Dry syrups require no cold chain before reconstitution, have longer shelf life as dry powder, and are significantly lighter to transport than pre-mixed liquid — all of which matter for markets with less reliable cold-chain infrastructure and higher shipping costs.

  • How do I verify a WHO-GMP certificate for an Indian syrup manufacturer?

    Request the actual certificate on CDSCO letterhead showing facility name, site address, licence number, dosage forms covered, issue date, and expiry date. Cross-reference at cdsco.gov.in.

    Reference: Central Drugs Standard Control Organisation (CDSCO)

  • What should a syrup Certificate of Analysis contain?

    A complete COA shows batch number, dates, assay, pH, viscosity, microbial limits, preservative content, and — for suspensions — dose uniformity data, with actual numerical results, not just pass/fail.

    British Pharmacopoeia 2024

  • Why does a dry syrup need two separate stability studies?

    Powder stability confirms the product survives storage before reconstitution. Reconstituted stability confirms the mixed suspension remains safe and effective for its labelled in-use period — these are genuinely different conditions requiring separate validation.

  • What is Artemether+Lumefantrine suspension and why does format matter?

    It is the WHO-recommended first-line paediatric anti-malarial treatment. As a suspension for children too young to swallow tablets, dose uniformity and correct reconstitution are clinically critical — confirm your manufacturer’s COA includes dose uniformity data specifically for this product.
