What it costs
The chamber’s Join Us page carries no rate card: it is a contact form. These figures are published instead in Chapter 3, Article 14 of their own By-Laws, and are carried here rather than treated as unpublished because a page prints them, even though it is not the page a first pass would check.
Natural person
Individual members.
Juristic person
Company and organisation members.
The chamber’s "Join us" page is itself a contact enquiry form rather than an application page: prospective members write in and the Chamber follows up directly. Join us, on mtcc.or.th
What members get
Partner offers as MTCC publishes them on its own Members Benefits page, each with their own validity window.
