Your First Glass Container OEM Order, Simplified

One of the most challenging steps for new cosmetic brands is packaging procurement. Glass container OEM involves more variables than plastic, including molds, finishing options, and accessory combinations, making the first order feel particularly daunting. This guide walks you through the actual process at JeongwooCos in 4 clear steps, from inquiry to delivery.

In a market where the average glass container MOQ exceeds 10,000 units, JeongwooCos offers production starting at just MOQ 5,000 pcs.

Step 1. Inquiry and Consultation: Designing Formulation and Container Together

The OEM process follows a formulation confirmation then container selection sequence. Having the following information ready will speed up your consultation.

Formulation type: serum, essence, cream, oil, etc.
Target volume: 15ml, 30ml, 50ml, 15g, 30g, 50g, etc.
Expected quantity: first production run (minimum 5,000 pcs)
Accessory preference: dropper, pump, cap, etc.
Finishing needs: frosting, color coating, PVD, printing, etc.

Tip: You can start container consultation even before your formulation is finalized. Container lead time (approx. 30 days) is often longer than formulation development.

OEM process 4 steps — Inquiry, sample, production, delivery - 4-step one-stop process

Step 2. Sample Review: Verify in Person

Once a suitable container is selected, request samples. Key items to verify at the sample stage:

Check Item	Checkpoint
Container appearance	Shape, clarity, wall thickness, weight
Neck compatibility	Dropper/pump/cap neck fitting check
Finishing sample	Frosting texture, color accuracy, print clarity
Content compatibility	Seal integrity after filling, discoloration check

Sample approval sets the standard for mass production. Review thoroughly before approving. Post-approval changes can result in additional costs and schedule delays.
