HIC (Humidity Indicator Card)

Cobalt Dichloride has been used as the main material in conventional HICs. However
EU lists Cobalt Dichloride as carcinogenic category 2, and requires to mark “R49” if
Cobalt Dichloride level exceeds 0.01%.

Our CDF Series are Cobalt Dichloride Free.

Strengths of CDF series
1. Color changes from Blue(dry) to Pink(wet) like conventional HICs.
2. Cost Effective
3. Passed Colorimeter Test under JEDEC standards


JEDEC and IPC published J-STD-033B Standard about handling, packing, shipping and
use of moisture sensitive surface mount devices, and HIC. Our HICs are in compliance
with the standard.
