In the customization of hardware structural parts, mold ownership is an issue that is frequently overlooked in procurement contracts yet often sparks disputes: once the mold fee is paid, who actually owns the mold? Can the mold be taken away if the supplier is changed? A common industry adage goes: “Who pays is just the starting point; actual ownership depends on the black-and-white terms of the contract.”
This article outlines three common models of mold ownership, relevant legal regulations, and key contractual points.
I.
Three Payment Models, Three Ownership Outcomes
- One-time Buyout: The mold fee is calculated separately from the product quote. Once the client pays the mold cost in full, ownership transfers to the client, who has the right to request the transfer of the mold at any time. This is the most common model and the most favorable to the purchaser.
- Amortized Cost: No mold fee (or only a partial fee) is paid upfront; instead, the mold cost is amortized into the price of each product until the accumulated orders offset the total cost.
Before the cost is fully offset, ownership usually belongs to the supplier or is shared by both parties; once offset, ownership transfers to the client as agreed. - Shared Ownership Based on Contribution Ratio: Both parties share ownership based on the proportion of mold costs they each paid, though the right of use belongs to the client.
According to industry contract templates, such arrangements typically specify that “the mold is jointly owned by both parties, while the right of use belongs to the buyer.”

Legal Perspective: Rules Under the Civil Code
Legally, mold manufacturing falls under the category of a contract for work (or contract for services).
According to the relevant provisions of the *Civil Code of the People’s Republic of China*, the transfer of property rights in movable property takes effect upon delivery; whether the mold has been delivered and whether payment has been settled directly affect the transfer of ownership and the supplier’s right of retention.
Judicial precedents indicate that when parties have a clear agreement regarding the ordering and payment of molds—and the fees have been fully settled—courts rule that ownership belongs to the paying party. However, in the absence of such an agreement, the mere possession of an invoice for mold-making charges often leads to disputes over the transfer and ownership of the molds.
In other words, ownership is not automatically acquired upon payment; rather, it is the result of the combined factors of “agreement, payment, and delivery.”

Molds Are More Than Just “Chunks of Iron”: Assets Require Separate Provisions
Senior legal experts advise that the mold itself, 3D drawings, machining programs, and trial-run parameters constitute four distinct categories of assets. The mold itself is movable property; its ownership is determined by the contract and the act of delivery. Drawings and machining programs involve intellectual property rights; the contract should explicitly state that these belong to the customer and prohibit the supplier from copying or imitating them. Trial-run parameters represent technical know-how and similarly require protection through confidentiality clauses.
Standard industry mold custody contracts typically stipulate that molds are manufactured according to customer specifications and that all intellectual property rights—including product appearance, patterns, and logos—belong to the customer;
suppliers are prohibited from modifying, copying, or imitating them without written consent.
Simply stating that “the mold belongs to the customer” is far from comprehensive.
IV. Five Key Contract Elements for Purchasers
- Mold Inventory: Itemize mold numbers, dimensions, and photographs to serve as a ledger and the basis for acceptance;
- Ownership Clause: Explicitly state that “ownership of the mold belongs to the buyer, with the supplier acting only as custodian,” and stipulate that this takes effect upon full payment of mold fees;
- Right of Inspection: Stipulate the customer’s right to inspect the mold’s condition at the supplier’s facility at any time;
- Obligation to Return: Stipulate that upon contract termination or at the customer’s request, the supplier must return the mold or destroy it according to the customer’s instructions within a specified timeframe;
- Outstanding Fees and Exclusivity: Clearly define the conditions for settling mold fees and stipulate that the supplier may not use the mold for third-party products (an exclusivity commitment) to prevent “multi-use of a single mold.”
V. Trend: Asset-Based Management of Molds
An increasing number of enterprises are now managing molds as formal assets. This involves maintaining digital records of mold codes, status, service life, and storage locations, ensuring traceability during factory transfers or production shutdowns;
practices such as mold insurance and third-party warehousing are also becoming widespread. Industry experts advise addressing mold ownership issues at the very start—upon contract signing—rather than waiting until a factory transfer occurs.
Ensuring consistency across the contract, payment terms, invoices, and acceptance documentation offers the most reliable guarantee of mold ownership.
