What is a three-piece tin can?
The three pieces are the cylindrical body, the bottom end and the top end. For tinplate packaging, the body material is tin-coated steel. The closure arrangement and final filling or closing process must be agreed for the intended product. “Three-piece” does not by itself establish food suitability, airtightness or resistance to a particular filling process.

Confirm the complete packaging system
Ask the supplier to confirm the can body, ends, coating and closing process as one specification. If your product has special content-contact or processing requirements, provide them before sampling. A sample approved for appearance alone does not confirm suitability for the intended contents.
Questions buyers ask
What sizes are available?
Share the diameter and height you need, or a measured reference sample. Available sizes and tooling requirements are confirmed by project; no standard size list is published here.
What is the minimum order quantity?
MOQ depends on the format, tooling and print requirement. Request a quotation for the quantity per size and design rather than assuming one site-wide minimum.
Can three-piece cans carry custom artwork?
OEM projects can include your branding. Share the artwork and requested finish so the proposed layout and sampling requirements can be reviewed.
