The CTC logo is composed of C (China) + T (Test) + C (Certification)—China Testing and Certification. Through simple variations in line design, it delivers a direct visual impression. With the letter T at the center and two identical C's on either side, the logo forms an abstract representation of a balance scale, symbolizing the corporate philosophy of impartiality and authority. The slightly slanted strokes convey a sense of dynamic movement, suggesting a readiness to advance—a reflection of our innovative pursuit to keep pace with the times and pursue continuous development. The sky-blue color represents rationality, wisdom, scientific rigor, and steady progress, foreshadowing CTC's vast development potential as expansive as the blue sky. Since its inception, the CTC logo has stepped into the public eye alongside the company's rapid growth, becoming increasingly recognized by a growing audience.
