Separate four places in the supply chain
Company address: where an entity receives official correspondence. Printing location: where the selected artwork is applied to a case. Stock or assembly location: where blank cases and components are held or prepared. Dispatch location: where the finished order enters the delivery network. One address may serve several roles, but a company address alone does not establish any production step.
For a project with several designs or phone models, ask whether the answer applies to every requested combination. A supplier may need to confirm details for the actual order rather than make a blanket statement about its entire catalog.
Ask questions that can be answered for your project
- Which step happens where? Ask for the city and state where your artwork would be printed, and identify the specific process you are asking about.
- Who operates that step? Distinguish the business operating the printing site from a warehouse provider, brand storefront, or registered agent.
- What is still unknown? Ask separately where the blank case originates, where any other finishing occurs, and where the order ships from. Do not fill gaps with assumptions.
- Does the answer cover every item? Share your exact model and design list. Request a project-specific answer if your mix could use more than one workflow.
- How should it be described? Agree on the precise wording for an internal procurement record before using it in your own marketing. A printing-location statement should not silently become an all-components origin claim.
These questions help compare suppliers. They are not a legal determination of country-of-origin labeling; seek appropriate advice before making a regulated origin claim.
What OneTwo can say about its own printing
OneTwo Tech Inc. operates phone case UV printing at 20531 E Walnut Dr N, Walnut, CA 91789 and 14210 Telephone Ave, Chino, CA 91710. Those are confirmed printing locations for our business, not evidence that every blank case or accessory is made in the United States. Our U.S. phone case UV printing page explains the business inquiry route.
For a particular order, contact the team to confirm the requested phone models, artwork, quantity, production terms, and which location or steps apply. Do not treat either address as a walk-in counter or a destination for unsolicited samples or returns. Ask before visiting or shipping anything.
Keep a short, dated supplier record
Write down the requested products and the supplier's response in separate fields: artwork printing location, blank-case origin, other processing, dispatch location, and items still to confirm. Add the date and the name of the person who answered. If the order mix changes, ask again rather than copying the old answer into a new purchase order.
Then use the artwork brief to define the actual designs and models, and the quote comparison worksheet to compare commercial terms on the same assumptions. Neither worksheet substitutes for a written, project-specific supplier answer.
