Frequently asked questions

What is the difference between OEM and ODM at GDK?
With OEM, GDK manufactures to your specification. With ODM, GDK develops the formula, package and concept for your brand, then manufactures it. Both follow the same 10-step process and quality system.
How is my product information protected?
An NDA is signed in step 3, together with the quality test agreement, before any concept, package or formula development begins.
Can I get samples first?
Yes. GDK's value chain starts with Samples & Market Approaches: we propose samples and a market approach before moving to customised development.
When is quality tested during development?
At three points: quality test criteria are agreed with you in step 3, the product is assessed for usability, compatibility, stability and safety in step 5, and ingredients and packaging materials are inspected in step 8 before production.
When is the final product confirmed?
In step 6, after the concept, package and formula are developed (step 4) and assessed (step 5). The order and manufacturing schedule follow in step 7.
Does support end at delivery?
No. Step 10 is delivery of product and marketing support, so the marketing concept developed in step 4 carries on after launch.
