You can learn more in one email than in three factory visits, if the email asks the right things. These are the ten questions worth sending before you commit anything — with the answer you should expect, and the answer that should make you slow down.
Copy them straight into your first message if that is useful.
1. Which company name holds the certificates, and is it the company invoicing me?
Expect: one company name, given immediately, matching the quotation. Worry if: the certificate is in a different name from the invoice, or the answer is vague. That usually means you are talking to a broker who will place your order elsewhere.
2. Where does the blending physically happen, and can I visit?
Expect: an address, and a yes. Manufacturers are generally pleased to show people the line. Worry if: the visit is deferred, or the only space offered is a meeting room and a showroom.
Seeing the filling line also tells you, in thirty seconds, whether they can actually make your format.
3. Is my product type inside your certified Halal scope?
Expect: a yes or no, and an offer to send the certificate page listing it. Worry if: the answer is "we are Halal certified" without addressing the scope.
Halal certification is scoped to specified product categories. A plant certified for beverage powders is not automatically certified for savoury seasoning.
4. Which of GMP, HACCP, ISO 22000 and MeSTI do you hold, and under what numbers?
Expect: certificate numbers, and copies on request. MeSTI in particular is a legal prerequisite for manufacturing food in Malaysia — a factory without it should not be making your product. Worry if: you get logos on a website but no numbers.
For reference, D&O holds Halal (JAKIM, MS 1500), GMP (SIRIM QAS, MS 1514:2022, cert. GMP 00203), HACCP (SIRIM QAS, MS 1480:2019, cert. HACCP 00425), ISO 22000 (cert. FSMS 00229) and MeSTI (cert. ME0523069-0/1).
5. Which fill formats do you run in-house?
Expect: a specific list — sachet, stick pack, jar, tin, bottle, bulk — and a straight answer about whether yours is among them. Worry if: the answer is "anything you need". Filling lines are physical equipment; nobody runs every format.
If your plan is a sachet box for social commerce and the factory is geared for 25 kg drums, that is the wrong factory however good its formulation team is.
6. Under an OEM arrangement, who owns the formula?
Expect: you do, and they will put it in writing before development starts. Worry if: the answer is comfortable but verbal.
Ask the follow-up too: what happens to the formula if you move production elsewhere later.
7. Do you manufacture your own retail brands in this category?
Expect: a direct answer either way. Some good manufacturers do; the point is knowing. Worry if: the question is deflected.
D&O does not sell competing retail brands in the categories it manufactures.
8. What is the sample process, and what does it cost?
Expect: a clear sequence — brief, costing, bench sample, revision, pilot run, production — and a clear statement of what is chargeable. Worry if: samples are promised instantly with no brief. A sample produced before anyone has asked your target price is a stock product with your name on it.
At D&O the first bench sample is free and made to your brief.
9. What decides the minimum order quantity for my product?
Expect: an explanation — format, fill weight, run size, changeover — and a number quoted against your specific brief. Worry if: a single MOQ figure is quoted before anyone has asked what you want made. That number cannot be meaningful yet.
10. Who is my contact when something goes wrong?
Expect: a named person, and a sense of who covers production versus quality versus commercial. Worry if: the only channel is a shared inbox.
Most of the value in a manufacturing relationship shows up on the day something does not go to plan.
The short version you can paste into an email
- Which company holds the certificates, and does it match the invoice?
- Where is the blending done, and can I visit?
- Is my product type inside your certified Halal scope?
- Which of GMP, HACCP, ISO 22000, MeSTI do you hold, and under what numbers?
- Which fill formats do you run in-house?
- Who owns the formula under OEM?
- Do you make competing retail brands?
- What is the sample process and what does it cost?
- What decides the MOQ for my product?
- Who is my named contact?
If a supplier cannot answer those ten in one reply, that is itself the answer.
Frequently asked questions
How do I tell a manufacturer from a trading company? Ask where the blending happens, who runs quality control, and whether you can visit. A manufacturer answers all three immediately.
Should I ask for the certificates up front? Yes, and check three things on each: the company name matches, the scope covers your product, and the certificate is current.
Is it rude to ask whether they make competing brands? No. It is a normal commercial question and a good manufacturer expects it.
What if the MOQ is too high for me? Ask what would change it — a different format, a simpler formula or a longer first run often move the number more than negotiating does.
Can I ask these questions of D&O? Please do. Every answer above is ours, and the certificates are supplied on request — send us your brief.
