Anyone can print “quality assured” on a carton. If you are a distributor, hospital procurement officer, retail chain buyer or private label client, you need a way to tell the difference between a company that means it and one that has simply bought the right font.
The five signs below are things you can actually check. None of them require you to be a pharmacist. All of them are difficult to fake under questioning.
Sign 1: They Own Their Production
Start here, because it determines who is accountable for everything else.
Many companies selling medicine do not make it. They outsource to third-party contract manufacturers, put their own label on the output, and distribute. This is a legitimate business model and some contract manufacturers are excellent. But it introduces a layer between you and the quality decisions.
When you ask an outsourcing company why a batch behaved unexpectedly, they have to ask someone else. When you ask about raw material sourcing, they may not know. When you want a corrective action, they have to negotiate it with a supplier who has other clients.
What to ask: “Do you manufacture this product in your own facility, or is it contract manufactured?”
What good looks like: A direct yes, with the site named, and a willingness to discuss what happens on that site — formulation, sourcing, in-process checks, final release.
Warning signs: Evasiveness. Answers that describe the company’s “network” or “partners” without naming a facility. Inability to say who performs final release testing.
If a company does outsource, that is not disqualifying — but they should be able to name the manufacturing site, show its licence and GMP status, and describe how they audit it.
Sign 2: Raw Materials Are Tested, Not Trusted
Bangladesh imports 80 to 90 percent of its active pharmaceutical ingredients, largely from India and China. That makes incoming material control the single highest-leverage quality step in the whole operation. A perfect production process cannot fix a wrong starting material.
A serious manufacturer treats every incoming consignment as unverified until proven otherwise: material arrives, goes to quarantine, is sampled according to a defined plan, is identity-tested and assayed in-house, and only then moves to approved status. Suppliers themselves are qualified before first use and re-assessed periodically, with audits for critical materials.
The weak version of this is accepting a supplier’s certificate of analysis at face value and releasing the material into production. It is faster, cheaper, and it is how substandard and adulterated ingredients enter finished products.
What to ask: “What testing do you perform on incoming active ingredients, and do you rely on supplier certificates of analysis?”
What good looks like: Description of a quarantine and release process, in-house identity testing at minimum, a written supplier qualification programme, and named responsibility for material release.
Warning signs: “Our suppliers are reputable.” That is not a control.
Sign 3: Every Batch Has a Traceable Record
This is the test that separates functioning quality systems from decorative ones, and it is the easiest to verify.
Take a product you already hold. Read the batch number off the strip. Ask the manufacturer to trace it.
A company with a working system can tell you, within hours: when it was made, which raw material lots went into it, which equipment was used, what the in-process check results were, who signed each stage, whether any deviation occurred and how it was resolved, what the finished-product test results were, when it was released, and where it was distributed.
A company without one will offer a general reassurance about their commitment to quality.
Batch traceability is not a nicety. It is what makes a targeted recall possible. Without it, a company facing a problem has only two options: do nothing, or recall everything. Both are bad, and one of them is dangerous.
What to ask: “Here is a batch number from a product of yours. Can you walk me through its record?”
What good looks like: Willingness to do it, a specific timeframe for the answer, and detail rather than summary.
Warning signs: Delay, deflection, or a response that describes policy rather than the batch.
Sign 4: Quality Has Authority Over Production
In every pharmaceutical company there is a structural tension. Production is measured on output and schedule. Quality is measured on compliance. When a batch is borderline and a shipment is due, those two pull in opposite directions.
How that tension is resolved tells you almost everything.
In a properly built organisation, the quality unit reports independently of production, and quality alone releases or rejects a batch. Nobody in commercial or manufacturing can override that decision. An out-of-specification result triggers a documented investigation before any disposition, not a retest until a passing number appears.
You cannot see the organisation chart from outside, but you can probe the culture.
What to ask: “Tell me about a batch you rejected in the last year. What happened and why?”
What good looks like: An actual example, described without embarrassment, including the investigation and the corrective action. Rejection is normal in a working system.
Warning signs: “We have never had to reject a batch.” Either they are not testing rigorously, not documenting, or not telling you the truth. Perfect records over years are a red flag, not a boast.
Follow-up question: “What is your out-of-specification investigation procedure?” The answer should describe root cause analysis and corrective and preventive action, not just retesting.
Sign 5: Complaints Are Investigated, Not Managed
How a manufacturer handles a complaint reveals whether quality is a system or a department.
The weak model treats complaints as customer service: apologise, replace the product, close the ticket, move on. Nothing is learned, and if the complaint indicated a real batch problem, that problem stays in the market.
The strong model treats every product complaint as a potential quality signal. The complaint is logged against the specific batch record. The retained sample from that batch is examined. The quality unit investigates whether the issue is isolated or systemic. If systemic, the remaining batch is assessed for recall. A written response goes back to the complainant. And the complaint feeds into a trend review that looks across time for patterns no single complaint would reveal.
What to ask: “What happens internally when a pharmacy reports a problem with one of your products?”
What good looks like: The words “batch record,” “retained sample,” “investigation,” and a named quality function. A description of who responds and within what timeframe.
Warning signs: An answer that begins and ends with product replacement.
Two Quick Additional Checks
Documentation on demand. Ask for a GMP certificate, a manufacturing licence, and a product specification sheet. A prepared manufacturer sends these the same day. Check the dates and check that the certificate covers the specific site and dosage form you are buying, since GMP certification is site- and line-specific.
A site visit. Serious buyers should visit. You do not need to be an auditor to notice whether gowning procedures are followed when nobody is performing for you, whether quarantine and released material are physically segregated, whether equipment logs are filled in contemporaneously or completed in one handwriting at the end of the week, and whether the quality laboratory looks used.
A manufacturer confident in their operation will schedule the visit. Reluctance is data.
Why This Matters More in 2026
Bangladesh’s Drugs and Cosmetics Act 2023 replaced legislation from 1940 and 1982, made WHO GMP compliance an explicit statutory requirement, brought cosmetics and medical devices under DGDA authority, and introduced severe penalties — up to life imprisonment — for manufacturing or selling contaminated products.
At the same time, LDC graduation is pushing the sector toward more demanding export markets where buyer audits are routine. The gap between manufacturers with genuine quality systems and those with certificates is about to become commercially visible in a way it has not been before.
For buyers, that is an opportunity. The questions above will get better answers from good manufacturers this year than they would have five years ago, and worse answers from weak ones.
Frequently Asked Questions
What is the difference between quality assurance and quality control?
Quality control is the testing function — analysing samples against specifications. Quality assurance is the wider system that ensures the process itself produces compliant product: procedures, validation, training, documentation, deviation management.
Can a small manufacturer have a strong quality system?
Yes. Scale determines capacity, not rigour. A small facility with disciplined documentation and genuine quality independence can outperform a large one with weak culture.
How often should I audit a supplier?
Common practice is an initial qualification audit followed by periodic re-audit, with frequency based on risk — more often for critical products, sterile forms, or after any quality incident.
What does a batch number tell me?
It identifies the specific production run. It is the key that unlocks the entire manufacturing history of the product in your hand, which is why products sold without a visible batch number should never be accepted.
Is a GMP certificate enough on its own?
No. Check what site and dosage forms it covers, when it was issued, and what the inspection history behind it looks like.
Summary
Five checks: they own their production, they test incoming materials rather than trusting them, every batch is traceable on demand, quality has authority to reject, and complaints trigger investigation rather than replacement.
PROMIXCO Pharmaceutical Limited operates its own production unit rather than outsourcing to third-party contract manufacturers. Raw materials are tested on arrival from approved suppliers, production follows documented batch records with in-process checks, finished goods are tested before release, and complaints are logged against the batch record and investigated by our quality team.
