I use a 73mm fruit can end as a metal closure designed for cans with a nominal end diameter of 73 mm. The correct buying decision depends on more than diameter: I also evaluate the can body, end profile, metal grade, coating system, opening design, sealing compound, production requirements, and filling process. For most B2B buyers, the safest approach is to confirm the complete can-and-end specification with a qualified supplier before placing a production order.

In this guide, I explain how I assess 73mm fruit can ends, which technical details should appear on a quotation, how to compare suppliers, and how to reduce compatibility and sourcing risks. I also show how Wanhua can support specification confirmation, sampling, production communication, and export-oriented purchasing discussions.
I prepared this guide for fruit processors, canned food manufacturers, private-label brands, importers, packaging distributors, and procurement teams. It is also useful for buyers who are replacing an existing supplier or developing a new canned fruit product. The information is intended for commercial evaluation rather than as a substitute for a final engineering drawing or process validation.
Buyers working with peaches, pears, lychees, mixed fruit, cherries, or similar canned products may have different requirements depending on acidity, syrup or juice formulation, thermal processing, storage conditions, and target market. I therefore recommend treating the product application as part of the specification. A closure that works for one can line or product formula may still require adjustment for another.
The term “73mm fruit can end” normally refers to a can end with a nominal diameter of 73 mm. In practice, the finished component includes several controlled features, such as the curl, countersink, panel, score line, rivet, compound area, and opening tab when applicable. The nominal diameter should not be used alone to approve a component, because the end must form a reliable double seam with the matching can body.
I ask suppliers to provide a technical drawing or approved specification showing the relevant dimensions and tolerances. A drawing may identify dimensions to a resolution such as 73.0 mm, but the actual acceptable tolerance must come from the approved design and manufacturing process. This distinction helps prevent buyers from ordering an end that appears correct by diameter but is unsuitable for the seamer or body profile.
Fruit can ends are commonly produced from coated steel materials selected for strength, forming performance, and resistance to contact with the packaged product. Depending on the project, the material may involve tinplate or another coated steel system, but the appropriate choice should be confirmed with the end manufacturer and the can maker. I do not recommend selecting material only by price, because coating compatibility and forming behavior can affect the finished package.
The internal coating is especially important for fruit packed in syrup, juice, or other acidic media. Buyers should request information about the coating type, internal lacquer suitability, external finish, and any printing or decoration requirements. If a coating system has not already been validated for the product, the buyer should arrange suitable compatibility evaluation before commercial filling.
I begin the selection process by reviewing the product and processing conditions. The buyer should identify the fruit type, filling medium, expected thermal treatment, storage environment, and intended shelf-life target. These details help determine whether the internal coating and sealing compound are appropriate for the application.
Processing equipment also affects the specification. The end must match the can body dimensions and the seaming chuck, lifter, and tooling used on the production line. If the buyer changes the end profile, body manufacturer, or seamer setup, the line may require technical review and adjustment before regular production.
Some fruit can projects require a standard end that is opened with a separate tool, while others may require an easy-open design. An easy-open end may involve a scored opening panel, rivet, and tab, so the opening performance must be considered alongside sealing integrity. The final choice depends on the product positioning, consumer expectations, filling format, and validated package design.
I recommend that buyers specify whether the project needs a standard end or an easy-open end at the quotation stage. If an easy-open solution is requested, the supplier should confirm the score design, tab format, internal coating, and compatibility with the can body. These details should be reviewed through samples or trial production rather than assumed from the nominal diameter.

A clear request for quotation reduces back-and-forth communication and makes supplier comparisons more meaningful. I normally include the nominal diameter, end type, material preference, coating requirements, decoration requirements, opening style, packing method, destination, estimated annual volume, and target delivery schedule. If an existing end is being replaced, I also provide a drawing, photos, physical samples, or the current supplier’s specification where permitted.
Material thickness is another item that requires careful confirmation. As an example, a buyer may investigate a starting thickness around 0.20 mm, but this is only a reference for discussion and is not a universal requirement for every 73mm end. The final thickness must balance forming, seaming, strength, product conditions, and the requirements of the can body and production line.
| Specification Area | Information to Confirm |
|---|---|
| Size and profile | Nominal diameter, countersink, curl, panel, and dimensional tolerances |
| Material | Steel type, nominal thickness, temper, and forming requirements |
| Coating | Internal lacquer, external finish, product compatibility, and curing requirements |
| Opening format | Standard or easy-open design, score line, tab, and opening expectations |
| Commercial terms | Quantity, packaging, sampling, production schedule, shipment terms, and payment conditions |
I first check whether the supplier can work from the buyer’s actual can specification instead of quoting only from the phrase “73mm fruit can ends.” The supplier should be willing to review drawings, samples, can body details, and seaming requirements. This step is essential because nominal size alone does not prove mechanical compatibility.
I ask how the supplier controls dimensions, coating appearance, curl quality, score consistency, compound application, and packing condition. Buyers should request the supplier’s inspection approach and agree on which characteristics are critical before production. If a supplier cannot clearly explain how quality is checked, the buyer may face avoidable uncertainty during incoming inspection or line trials.
Samples allow the buyer to compare the physical end with the approved drawing and test compatibility on the intended can line. I recommend recording at least three dimensional readings per sample area where practical and documenting any visible defects, coating concerns, or fit issues. Sample approval should be written and linked to a defined revision of the specification.
Price is only one part of the total sourcing decision. I compare minimum order quantity, tooling or setup charges, packaging, production capacity, lead-time assumptions, export experience, communication quality, and the supplier’s ability to maintain the approved specification. Buyers should ask whether the quoted lead time starts after artwork approval, sample approval, deposit receipt, or another milestone.
The cost of 73mm fruit can ends depends on material, thickness, coating, opening design, decoration, order volume, packing method, tooling, and shipping destination. I avoid presenting one universal price because these variables can change the commercial result substantially. A lower unit price may not be the best option if it requires unsuitable packaging, creates a long approval cycle, or increases line-trial risk.
MOQ also varies by supplier and configuration. Standard products may be easier to source than customized profiles, printed finishes, or special opening systems, but buyers should confirm this directly in the quotation. For planning, I ask suppliers to separate sample timing, approval timing, production lead time, and shipping time so that the purchasing team can build a realistic schedule.
At Wanhua, I approach 73mm fruit can ends as a complete packaging component rather than an isolated metal disc. I can help buyers organize the required dimensions, material preferences, coating needs, opening format, application details, packing expectations, and commercial volume into a clearer inquiry. This gives our technical and sales teams a practical basis for evaluating the requested solution.
Our support can include specification discussion, sample coordination, production communication, packaging confirmation, and export-order follow-up. The exact product configuration, MOQ, lead time, and available customization should be confirmed for each project because they depend on the design and order requirements. I also encourage buyers to share their existing drawing or sample when replacing a current supplier.
To source the right 73mm fruit can ends, I recommend preparing a concise technical brief with the nominal size, can body information, fruit product, filling medium, processing conditions, opening format, material preference, coating requirements, order quantity, destination, and target schedule. Then request a drawing, quotation, sample plan, inspection details, and commercial terms from the supplier. Finally, approve the sample against the intended can body and seaming process before starting regular production.
The direct answer is that the best 73mm fruit can end is not simply the lowest-priced end marked “73mm.” It is the end whose dimensions, material, coating, opening system, compound, and production controls are demonstrably compatible with your can and fruit product. Contact Wanhua with your drawing, sample, or project requirements, and I can help you begin a structured evaluation for your next 73mm fruit can end order.
