How a Korean Soju Brand Got 200,000 Custom Bottles in 18 Days for New Year Launch

A Korean soju brand's design studio discovered just 20 days before the New Year launch that their original supplier could not deliver 750ml custom soju bottles on time. By providing tiered pricing for fast order confirmation, a transparent production schedule, and 100% in-house inspection, we produced and delivered 200,000 custom glass bottles to the Korean filling plant within 18 days — 2 days ahead of the client's deadline. The client subsequently added us as their preferred supplier with a full-year supply contract.

For a seasonal spirits release, missing the launch window means losing an entire year of sales. This case study breaks down exactly how we compressed production, inspection and ocean shipping into an 18-day window — including the 48-hour production schedule that gave the client confidence to commit.

The client is the founder of a well-known design studio based in Seoul, Korea, acting on behalf of their brand client. The end client is a mid-to-premium soju brand in Korea, with products sold through convenience stores, restaurants, and gift channels. The project was directly tied to the brand's image, production schedule, and New Year product launch — there was zero margin for error.

The client contacted us through a B2B platform with an initial requirement of 200,000 units of 750ml custom soju bottles. The specification called for high-white glass, a classic soju bottle silhouette, but with a customized shoulder curve and a proprietary embossed design on the bottle base.

After sample approval and just before the order was to be placed, the client raised two urgent concerns:

• Extremely tight lead time: The client required all bottles to arrive at the Korean filling plant within 20 days to meet the New Year launch window. Standard soju bottle production and ocean shipping typically take 35–45 days.
• Serious quality concerns: The client admitted that past purchases of glass spirits bottles from China had suffered from high breakage rates — bottles could not withstand the pressure of automated filling lines, causing frequent line stoppages and yield losses. The client stated clearly that if the same problem occurred again, they would permanently abandon Chinese suppliers.

In addition, producing 200,000 units in 18 days is an extreme capacity scheduling challenge for any glass bottle factory.

The client's concern was not unreasonable — a bottle that cannot survive the filling line is a liability, not a saving. What they needed was evidence, not promises.

We did not offer vague promises. Instead, we responded to the client's two core concerns with data-driven and visual proof.

• Lead time: Production to delivery completed in 18 days. The client's New Year launch proceeded as scheduled.
• Breakage rate: The client's filling line reported a breakage rate below 0.5%, far better than the previous supplier's 5%–8%. The filling line experienced no stoppages due to bottle quality issues.
• Client feedback: After receiving the goods, the client proactively sent this message: "NEWRAY proved its professionalism through action. They are not just a supplier, but a truly reliable solutions partner."
• Long-term partnership: The client named us their preferred supplier and added multiple full-year supply contracts covering regular products and holiday special editions.
