A 73mm fruit can end is a can closure identified by a nominal 73 mm size, but that designation alone is not enough to confirm compatibility with a can body or seaming line. Buyers should verify the end profile, material and coating, opening style, seam requirements, and suitability for the product’s filling and processing conditions. In this guide, we explain what to include in an inquiry and how to assess suppliers so you can request a more accurate quotation and evaluate samples against your own packaging requirements.
You can find more information on our web, so please take a look.
This guide is for fruit can manufacturers, food packers, packaging distributors, and sourcing teams assessing 73mm can ends. It is especially relevant when you are qualifying a new supplier, changing a can format, or troubleshooting fit and seaming concerns. The information can also help purchasing and engineering teams align on the technical details needed before comparing offers.
End requirements vary by can design and production setup, so this guide does not prescribe a universal end profile or a guaranteed specification. Your can maker, seaming-equipment provider, and end supplier should confirm the applicable dimensions and process requirements together. For a specific project, use the approved drawing or a verified sample as the reference.
A fruit can end is the closure fitted to a metal can, commonly joined to the can body by a double seam. The “73mm” label identifies the nominal size used to describe the format; it does not, by itself, define every dimension or prove that the end will fit a particular can body. The end’s curl, countersink, panel profile, compound, and other design details may also matter to fit and seam formation.
Can ends help close and protect the filled package, but performance depends on the complete can system. The body dimensions, end geometry, seaming rolls and chuck, machine setup, and product process all contribute to the final package. A supplier’s confirmation should therefore be based on the intended can and line details rather than on the size designation alone.
Ask what metal substrate and coating options are available for the exact end design. Suitability depends on the food product, contact conditions, filling and processing method, and the relevant requirements in the destination market. Request the supplier’s product documentation for the proposed material and coating, then have your technical or regulatory team assess whether it meets your project needs.
Do not assume that two ends with the same nominal diameter use the same substrate or internal coating. The coating selection should be reviewed for the actual contents and processing conditions, including any factors your team identifies as relevant to product compatibility. If your specification names a material or coating, include it in the inquiry and ask the supplier to confirm it against the offered product.
Confirm whether the project requires a plain end or an opening feature, such as an easy-open design, and specify the intended opening arrangement. Availability depends on the supplier’s product range and the complete package design, so request confirmation rather than assuming a particular style is standard for every 73mm format. The end profile and curl should also match the can body and the seaming setup.
Provide the approved drawing or sample wherever possible. At minimum, ask the technical teams to confirm the end’s relevant dimensions in mm, including the nominal diameter and the profile details needed to establish fit and seam compatibility. The required values must come from the can design and equipment requirements; they should not be inferred from the 73mm designation.
| Specification area | What to confirm | Why it matters |
|---|---|---|
| Nominal size | 73 mm designation and the supplier’s reference drawing | Establishes the format for initial matching, but does not prove compatibility by itself. |
| End profile | Curl, countersink, panel, and other specified geometry | These details can affect fit and seam formation. |
| Material and coating | Substrate, coating description, and supporting product documentation | Allows review against the food product and applicable market requirements. |
| Seaming requirements | Compatible can body, seamer setup, and acceptance criteria | Supports evaluation of the complete closure system in production conditions. |
| Supply details | Quantity, packing method, destination, and requested delivery window | Enables a supplier to prepare a relevant commercial offer. |
Start with the can body that will actually be used, not a general description of the product. Share the body specification, drawings, or a physical sample and identify the seaming equipment where the end will be applied. If the package will undergo a defined filling or thermal process, communicate the relevant process conditions to the supplier and confirm that the proposed end is suitable for evaluation under those conditions.

Also describe the contents and how the can will be handled and distributed, since these details inform the technical review. Do not treat a supplier’s general product description as evidence of suitability for every fruit product or process. Your quality and engineering teams should define acceptance criteria for the package and review the results from a trial using the intended materials and line setup.
The trial is a buyer-side validation step, not a substitute for supplier documentation or engineering review. Agree in advance who will supply the can bodies, what inspection method will be used, and how findings will be recorded. If the trial identifies a mismatch, pause approval and resolve the specification before moving to routine purchasing.
Pricing for a can end depends on the confirmed specification and the supplier’s commercial terms. Factors to clarify may include material and coating, opening style, order volume, packing configuration, customization, and delivery destination. A 73mm description without a drawing or material details may not provide enough information for a like-for-like quotation.
Minimum order quantities and lead times are supplier- and project-specific; we recommend requesting them directly rather than relying on a general estimate. Ask whether sample quantities are available, whether a production schedule depends on specification approval, and how the supplier defines the delivery point. Compare the full offer, including packaging and shipping assumptions, rather than comparing unit prices alone.
Clear answers make it easier to compare suppliers and reduce the risk of an order being placed against an incomplete specification. If key details remain open, record them as questions or conditions in the inquiry rather than treating them as confirmed. This creates a shared reference for purchasing, engineering, quality, and the supplier.
At Wanhua, we can review your 73mm fruit can end inquiry against the information you provide and discuss the specification, application, and commercial details needed for a quotation. To help us assess the request, share your drawing or sample reference, can-body information, material and coating requirements, opening style, order quantity, destination, and target delivery window. We can then clarify which points require technical confirmation before an offer or sample evaluation.
Where compatibility is not yet established, we recommend agreeing on the reference dimensions and trial responsibilities with the relevant packaging and equipment teams before production approval. This approach helps keep the discussion grounded in your actual package rather than assumptions based on nominal size.
A 73mm fruit can end is a starting point for specification, not a complete purchase description. Confirm the end profile, material and coating, opening style, body compatibility, and seaming requirements using an approved drawing or sample. Then evaluate the offer’s MOQ, lead time, documentation, and delivery terms, and validate the proposed end in a controlled trial on the intended package.
For your next step, prepare the can-body reference, application details, required quantity, destination, and any technical documents you have available. Send them to Wanhua for an initial sourcing discussion, and identify any open technical questions before requesting final approval. A precise inquiry gives both buyer and supplier a clearer basis for quotation and evaluation.
