Courier sample delivery and on-site pickup are both supported. In Shenzhen, engineer home visits can be booked; Dongguan and surrounding areas can arrange dedicated vehicles; out-of-town clients simply follow our sample submission guide. We have bases in Tangxia, Dongguan and Bao'an, Shenzhen, allowing nearby scheduling.
How do I submit samples? Can out-of-town clients ship them?

Will you subcontract our projects?
Projects within TMC's own capabilities are always done in-house. For the occasional specialty project requiring a partner laboratory, we'll tell you in advance and honestly note the subcontractor and subcontracted items on the report. Passing off subcontracting as in-house capability is against this industry's bottom line.
What if my client/certification body doesn't accept your reports?
Before submission, give us the client's original requirements — do they need English reports, a designated laboratory, or extra formatting requirements? After verification, we give you written confirmation: if we can meet them, we proceed directly; if not, we tell you directly — no wasting your time.
We already have a regular partner laboratory — why choose you?
We're not asking you to replace your existing supplier — we want to be your second supplier. When they can't fit your deadline or can't do certain items, you have an emergency option. The first order can start with a small project — expand once you find us reliable.
Will testing timelines delay our mass production milestones?
Let's work backward together. Tell me your report date and count back: report preparation N days, testing itself N days, sample receipt confirmation 1 day — that determines the latest day samples must reach us. I'll send written confirmation of that date, and both sides will track it together.
The budget hasn't been approved yet — can you give a quotation first?
No problem. I'll compile the plan, quotation and justification into a document you can hand directly to leadership, clearly stating the risks of not doing this testing (customer rejection, rework, line stoppage). It'll be easier for leadership to approve; once approved, we can start anytime.
Still have unresolved questions?
