Small-part finishing for factories in TFD Industrial Estate
TFD is the newer of the Chachoengsao estates on this site, at Tha Sa-an in Bang Pakong, and it contains a free zone — which changes the paperwork around a subcontracted job more than it changes the job.
We run one plant, and it is in Samut Sakhon. This page covers collection and delivery for customers in Chachoengsao — it is not a branch or a facility in Chachoengsao.

IEAT-designated covers both estates operated by the Industrial Estate Authority of Thailand and joint-operation estates run with a private developer. A dash means we could not confirm a single status for the whole area — some of these names describe a factory district rather than one designated estate.
A dash in the port row means the estate sits inland between two ports and we will not guess which is nearer. Nothing on this page is a distance, a drive time or a delivery-time promise.

What this estate is
TFD is an IEAT joint-operation estate run with a private developer, at Tha Sa-an in Bang Pakong district, Chachoengsao, inside the Eastern Economic Corridor. IEAT’s own record dates the estate to 2550 in the Thai calendar, which makes it the newest of the three Chachoengsao estates on this site, and it divides the land into a general industrial zone and a free zone. Two rows on this page are blank — the corridor and the port. IEAT’s record for this estate names no highway number, and Bang Pakong sits between Bangkok Port and Laem Chabang, so neither row is filled in by guesswork.
What this estate asks of a small part
Two things shape the work from here. The first is the material spread you get from a general industrial zone, which is why the material designation on the drawing is the first thing we ask for. The second is the free zone. When parts leave the zone for finishing and come back, they move under customs control, and the part we can actually govern is that the delivery note and the test record match the part numbers and quantities we received, exactly, and that any rework is traceable to the pieces it was done on. We do not advise on your customs procedure — that is your broker’s work, and we will not pretend otherwise — but our paperwork will not be the reason your figures fail to reconcile.
Services for factories in this estate
Hardening, Cr3+ zinc plating, phosphate coating and in-house lab testing, all on small parts at bulk volume.

The corridor row is deliberately empty. IEAT’s record for this estate gives the address at subdistrict and district level without a highway number, and the roads around Bang Pakong include the Bangna–Trat corridor and the Chachoengsao side roads, so we do not pick one on the estate’s behalf. The actual collection route is planned with sales, lot by lot. The port row is empty for the same reason as the other two Chachoengsao estates: we have nothing that grounds which port is nearer.
Questions we get from this estate
Which highway and which port serve this estate?+
Because we could not ground either one. IEAT’s record for this estate names no highway number, and Bang Pakong lies between Bangkok Port and Laem Chabang. We would rather show a gap with a reason than a confident-looking value we invented. Everything else on the page — province, district, IEAT status, EEC status — is checkable.
We are inside the free zone. Can parts go out for finishing?+
The customs procedure belongs to your broker and your own customs team; we do not advise on it and will not pretend to. What we control is the processing side: the lot is counted and recorded against your part numbers, the delivery note and the test record that come back state matching quantities, and if anything is reworked we say in the paperwork which pieces and what was done, so your figures reconcile.
