Water — Manufacturer Sourcing Guide

How to find, ask, vet, and choose a Thai factory to bottle your own purified-water brand — in plain English, start to first delivery.

Project: Water Market: Thailand 🇹🇭 Path: OEM / private-label Updated May 2026

The big picture (read this first)

You are not building a water factory. You are renting one. This is called OEM (or "private label") — an existing, licensed factory bottles water and puts your brand on it.

In Thailand there are dozens of these factories that already have the machines, the licenses, and the experience. You bring the brand and the orders; they do the production. Most of them offer a "one-stop" package, which usually means three things:

🏭 What the factory does for you

  • Sources & purifies the water (RO / mineral)
  • Supplies the bottle, cap, and shrink-wrap
  • Prints your label (often designs it too)
  • Files the อย. (FDA) number for your product — often free
  • Delivers to you

🙋 What you do

  • Pick your bottle size(s) and quantity
  • Decide your brand name + label look
  • Compare factories and choose one (this guide)
  • Place the order and sell it 💰
  • Handle your own marketing & distribution
Why this matters: Going OEM means you can launch a real, legal water brand for a few thousand baht and a few weeks — instead of millions of baht and a year to build your own plant.

1 Your 7-step roadmap

From "I want to sell water" to "boxes arrive at my door." Each step feeds the next.

  1. Decide your basics. Bottle size(s), rough monthly quantity, budget, and who you'll sell to (shops? restaurants? events? online?). See "Decide first."
  2. Build a shortlist. Use the Thai search terms and the starter list to find 3–5 factories.
  3. Ask everyone the same questions. Message them on LINE / phone / email with the question list. Log answers in the comparison table.
  4. Get written quotes + free samples from your top 2–3. Always get pricing in writing (a LINE message is fine).
  5. Check the licenses (อย. / GMP) and, if you can, visit the factory or do a video walkthrough. See red flags.
  6. Lock the brand + label + อย. number. Most factories file the product registration for you — confirm it's included.
  7. Place a small first order, check the quality yourself, then re-order and scale up.

2 Decide these 4 things before you call

Factories will quote you faster and more accurately if you can answer these up front.

1. Bottle size(s). The 600 ml bottle is the everyday best-seller. You can start with one size and add others later. See the size table.
2. Rough quantity. Per order or per month. Be honest — small is fine to start, but it affects your price per bottle and which factories will take you.
3. Budget & price target. What can you pay per bottle, and what will you sell it for? Use the cost estimator.
4. Your buyer. Shops, restaurants, hotels, offices, events/temples, or online. This shapes size, label style, and quantity.

3 Bottle sizes & what they're for

SizeBest forUsually sold as
220 ml cup (แก้ว)Events, meetings, temples, seminars, giveawaysTray (~48 cups)
350 mlHotels, cafés, a "premium small" feelPack of 12
500–600 mlThe everyday best-seller — shops, restaurants, retailPack of 12
1,500 ml (1.5 L)Families, offices, dining tablesPack of 6
18.9 L gallon (ถัง)Offices & homes with dispensers, subscription deliverySingle bottle

"Pack" (แพ็ค) usually means a shrink-wrapped bundle. When a factory quotes a minimum in "packs," always ask how many bottles are in a pack.

4 Cost & minimum order — rough anchors

Real numbers vary a lot by factory, volume, label finish, and bottle size. Use these as a sniff-test, then get a written quote.

ItemRough figure (public, May 2026)Notes
Price per 600 ml bottle (OEM)from ~฿2.80; budget ~฿3–6Lower with higher volume & simpler label
Minimum order~500 packs / 600 bottles & upVaries widely — confirm bottles vs packs vs cases
"One-stop" starter packagefrom ~฿3,500Some include free อย. + label design + delivery
อย. factory assessment fee~฿3,000This is the factory's cost — in OEM it's already done
Lead time (first branded order)~30 daysFaster on repeat orders
Treat every number here as "verify me." These come from public manufacturer websites in May 2026 and are starting points, not quotes. Your real cost depends on your size, volume, and label.

5 Licensing made simple (อย. / GMP)

Drinking water is a regulated food in Thailand, controlled by the FDA (อย.สำนักงานคณะกรรมการอาหารและยา). It sounds scary; for an OEM brand owner it usually isn't, because there are two separate layers:

Layer 1 — The factory's license

The production site needs a food-production license and must pass a GMP (Good Manufacturing Practice) inspection. This is the factory's job and is already done if they're established. You just need to confirm it's valid.

Layer 2 — Your product's อย. number

Your specific branded label needs its own อย. serial number (เลขสารบบอาหาร) printed on it. Most OEM factories file this for you, often free as part of the package. Confirm before you commit.

Rough timeline if papers are in order: about 1 month. As an OEM brand owner you normally do not build a factory or hold a production license yourself.

What the factory's paperwork actually involves (background)

For their site license, a factory registers via the FDA e-Submission system (OPEN ID account), pays an initial assessment fee (~฿3,000), and passes a GMP inspection. Documents include the site map & layout, machine list, water-treatment system details, lab water-quality test results, and a sample label. You don't do this in OEM — but it's good to know what a legitimate factory has already been through.

6 Questions to ask every factory

Tick these off as you go. Ask all of them to each factory so you're comparing apples to apples.

Your ticks are saved in this file on this computer, so you can come back to them.

7 Red flags & how to vet

No valid อย. / factory license, or they won't show certificates → walk away.
Won't provide samples or a recent lab test. A real factory is proud to show these.
Verbal-only, vague pricing. Get every number in writing (LINE/email is fine).
Big deposit demanded before you've seen the factory or any proof. Be cautious.
Can't name other brands they already produce for.
Two quick checks that protect you: (1) Ask for the factory's อย. license number and verify it's real (the FDA food site is food.fda.moph.go.th). (2) Visit the factory in person if you can, or ask for a live video walkthrough.
