A 99mm tomato paste can bottom end is a closure component sized for a can system described as 99mm; that nominal size alone does not confirm compatibility. The end must match the can body’s opening, profile, material, coating, and seaming requirements. Before ordering, compare the supplier’s technical drawing with your can-body specifications and validate the match through a controlled production trial. At Wanhua, we recommend sharing the intended application and packaging details early so a supplier can assess the requirements before quotation.

This guide is for food-can manufacturers, tomato paste producers, packaging procurement teams, and importers sourcing 99mm can bottom ends. It is also useful when qualifying an alternative supplier or investigating a fit or sealing issue. The information is intended to support supplier discussions, not replace the specifications approved for your can line.
A can bottom end closes one end of a metal can body and forms part of the package’s mechanical and product-protection system. Depending on the can format, the end may be attached during can production or used as a component in a particular packaging process. Its profile and dimensions must work with the body and seaming equipment to create the intended closure.
For tomato paste packaging, the end is one part of a complete package rather than a standalone solution. The can body, end, seams, internal coating, filling process, and applicable processing conditions all affect whether the finished pack is suitable. A 99mm label by itself cannot establish that the closure will perform as required.
Ask for the supplier’s drawing and identify the exact dimensions that control fit and seaming. These may include the end’s outside diameter, curl or flange dimensions, countersink depth, and other profile details shown on the drawing. Confirm how the supplier defines “99mm,” since nominal product descriptions may not provide every measurement needed for production.
Do not assume that two ends with the same nominal diameter are interchangeable. Differences in profile or tolerances can affect feeding, alignment, and seam formation on your line. Use the drawing and can-body specifications together, and have the responsible packaging or engineering team approve the match.
End materials and protective coatings should be selected for the can design, filling and processing conditions, storage, and sales market. Options may depend on the supplier’s available product range and the customer’s approved packaging specification. Ask the supplier to identify the proposed substrate and coating clearly rather than relying on a broad description such as “food-grade metal.”
For a tomato paste application, confirm that the internal surface system is suitable for the product and the intended process. Obtain relevant material documentation and verify regulatory requirements with your own compliance team. Requirements can differ by destination market, so avoid treating one supplier statement as confirmation for every jurisdiction.
When preparing an RFQ, a team might list a nominal diameter of 99 mm and request the supplier’s proposed stock thickness in mm and countersink depth in mm. Any thickness or depth entered by the buyer must come from an approved can design, not from an assumed industry standard. Values such as 0.20 mm thickness or 3.0 mm countersink depth are examples of how dimensions may be written only; they are not Wanhua specifications or recommendations for this product.

Start with the can body that will receive the bottom end, not just an existing product name or catalog description. Provide the body drawing, the end drawing if available, and details of the seaming process to the supplier. If the packaging line has specific tooling or feed requirements, include those in the technical review.
Where a drawing is unavailable or an existing closure is being replaced, provide a representative can body and end for evaluation if your supplier can accept samples. Agree in advance on what will be checked and who will approve the result. A practical trial can compare 3 sample ends against the same can-body specification, but this is a suggested evaluation approach, not a universal test standard or substitute for your approved inspection plan.
There is no single reliable price or lead time for every 99mm bottom end. Quotation terms can depend on the selected material and coating, order quantity, tooling or customization needs, packaging method, destination, and current production schedule. Request a written quotation that separates product price, minimum order quantity, sample or tooling charges where applicable, packing details, and delivery terms.
Ask the supplier to state lead time in calendar days or working days and clarify when that period begins, such as after drawing approval or deposit confirmation. Also confirm whether the quoted MOQ applies to a trial order or only to routine production. These details help buyers compare offers on equivalent terms instead of comparing a unit price without the associated conditions.
Clear answers are more useful than general assurances. If any critical specification is unresolved, record it as an open point and obtain written confirmation before placing a production order. Keep the approved drawing and quotation associated with the purchase specification for future replenishment.
One common mistake is ordering by nominal diameter alone and assuming that every 99mm end fits every 99mm can body. Another is omitting the coating or material requirement, which can leave room for different interpretations during quotation. Buyers should also avoid treating an unapproved sample as proof that a production lot will meet the final specification.
Do not rely on informal verbal descriptions for critical dimensions or delivery commitments. Request the applicable drawing, written quotation, and agreed inspection or approval process. If your can format or market requirements change, review the specification again rather than assuming the previous approval still applies.
As a packaging and printing supplier, Wanhua can discuss your 99mm tomato paste can bottom end requirements and help organize the information needed for a sourcing review. Share your target application, can-body details, drawing, material and coating expectations, order quantity, and destination. With these details, our team can respond to the specific questions that need to be resolved for a quotation and compatibility assessment.
A 99mm tomato paste can bottom end is suitable for your project only when its actual dimensions, profile, material, coating, and seaming compatibility match the approved can system. The next step is to assemble your can-body information and requirements, request a supplier drawing and written quotation, and agree on how samples or a production trial will be evaluated. Contact Wanhua with your project details to begin a focused B2B sourcing discussion.
