Vegan cosmetics manufacturing
An EVE VEGAN certified facility gives brands a credible starting point for vegan product lines. Combined with GDK's plant-based ingredient work — from rice, mugwort and black soybean to patented plant-extract compositions — it supports brands targeting clean and conscious beauty consumers. Vegan claims for each product are reviewed per project.


Quality checks built into development
- Step 3 – quality test agreement: test items and criteria are agreed with you before development.
- Step 5 – assessment: usability, compatibility, stability and safety are evaluated.
- Step 8 – incoming QC: raw materials and packaging materials are inspected; only approved materials go to production.
GDK's QA department is staffed with qualified inspectors for packaging components and finished goods, aiming for quality, consistency and safety under GDK's own demanding standards and global regulatory practice. See the full process.

Fingerprint-free process
The same product, to the same quality, every time.
The same product should have the same quality whenever it is made. GDK runs a smart, automated process in which workers' hands do not touch the product:
Start → Automated cutting → Automated folding → Automated insertion → Automated filling → Automated packaging → Automated wrapping → Completion
Manufacturing facilities
GDK's head office and manufacturing site in Incheon combine large stainless steel manufacturing tanks with pipework and pressure gauges, pouch filling lines, conveyors and unit-carton packaging equipment. Capacity is 13,000 kg of bulk per day, 55,000 skincare units per day and 460,000 mask and patch units per day.
