How OEM Works
with YUMESEI.

Tell us what you want to create

Begin with the customer you want to reach and the product you have in mind. Our OEM Product Request Sheet (ORS) brings the commercial and technical questions into one brief, even if your idea is still taking shape.

• The category and product idea
• Who the product is for
• Ingredients you would like to include
• Preferred format and serving size
• Taste, aroma and texture direction
• Your packaging concept
• Expected volume and price target
• The country where you plan to sell
• Other market or business requirements

Choose your development route

The amount of development work should fit the project. We look at what is already available, what you want to change and the time and budget you can commit.

Build the base formulation

The Base Formulation (BF) is the first complete recipe for evaluation. It includes the ingredients behind your product concept, together with components that help the product taste, mix, keep and manufacture as intended.

Collagen peptides, botanical materials, vitamins or hyaluronic acid may be part of the brief. Their interaction with the rest of the recipe matters: a drink, powder or jelly needs a workable balance of flavour, texture and stability as well as a clear ingredient story.

Balance the formula with your target price

A price target is useful before the recipe is settled. The amount and grade of each ingredient, its source and the intended serving all affect cost. We review these choices alongside the customer experience and the market position you want.

• Brand positioning
• Consumer expectations
• Market requirements
• Quality level
• Target budget

Japanese laboratory evaluation

Before samples are prepared, the technical team checks whether the proposed recipe and pack can work with the selected manufacturing route. An initial review commonly takes around 1–2 weeks; the scope and materials can change that estimate.

• Ingredient compatibility
• Manufacturing feasibility
• Stability and taste
• Ingredient availability
• Packaging compatibility
• Production-line requirements
• Applicable manufacturing standards
• Commercial feasibility

Indicative timingTypical initial evaluation: approximately 1–2 weeks

Develop laboratory samples

Laboratory Samples (LS) let you evaluate the proposed product in practice. After the recipe direction and preliminary commercial basis are agreed, the team obtains the necessary materials and prepares samples. Allow roughly 2–4 weeks for this work, depending on the project. Any development charge is put to you for approval in advance.

• Taste, aroma and sweetness
• Acidity
• Texture and consistency
• Appearance and mixing
• Technical feasibility

Indicative timingTypical sample development: approximately 2–4 weeks

Taste, test and refine

Try the sample in the way your customer would use it. Describe the change you want in clear terms, such as a less sweet finish or a lighter texture, and use measurable feedback where possible. A project may include around 2–3 trial rounds; the agreed scope determines what is included and whether further work needs a new quotation.

Approve the product

Your accepted sample becomes the reference for the commercial product specification. We settle the recipe, production conditions, pack requirements and business terms so that manufacturing preparation has a clear basis.

Create your brand and packaging

Your brand direction guides the pack: the audience, visual identity, colours and product story should work together. Packaging support is agreed for the project, and artwork is normally supplied in production formats such as AI and PDF.

Confirm artwork and print proof

Print approval is a separate decision from liking the design. The artwork needs technical checks and corrections, followed by your sign-off. A suitable colour, material or physical proof may be used for the selected pack. Once the print run starts, a change can mean extra cost or waiting for another run.

• Proofread the text and numerical details
• Check the required label information and proposed claims
• Verify the barcode information
• Review the colour and layout proof
• Sign off the production artwork

Indicative timingCustomized packaging mass printing may take approximately 4 weeks

Made-in-Japan mass manufacturing

The production estimate starts once the required materials and manufacturing conditions are in place. A first run commonly needs around 4–8 weeks from that point. More involved projects can need about 12 weeks or longer; the facility confirms the schedule for your order.

• Product complexity
• Ingredient availability
• Packaging production
• Factory and line schedule
• Testing and quality requirements
• Order quantity
• Seasonal manufacturing demand

Indicative timingTypical first production: approximately 4–8 weeks after requirements are ready; complex projects can take longer

Documentation, export and international logistics

We help coordinate the documents and shipment preparations handled in Japan. The agreed commercial arrangement sets the responsibilities for delivery; possible terms include FOB, C&F/CFR or CIF.

Your importing team checks the destination market before the product goes into commercial production. This includes product classification, any registration, label details, allowed claims and entry requirements. A food-category route may be appropriate, but it depends on the complete formula and the country's rules.
