What a Tooling Amortization Clause Should Say for Custom Wellness Devices

What is a tooling amortization clause and why does it matter for your ODM project?

A tooling amortization clause divides the one-time cost of custom molds across a set quantity of units, so both you and the factory share the risk of that upfront investment. When you commission a custom product — a heated massager housing, a silicone cover for an eye mask, a molded bezel for a red light panel — the factory must machine a mold before the first unit can be produced. That mold costs real money, and the factory carries that cost until you buy enough units to repay it.

Industry-typical tooling costs for small plastic and soft-touch parts range from roughly $3,000 to $30,000 per mold, depending on cavity count, material, and surface finish. Most factories amortize tooling over 12-24 months or a fixed unit volume. The amortization clause is the contract language that governs who owns that mold, how fast it gets repaid, and what happens if your project stalls.

Buyers who skip this clause often discover, mid-project, that their "free tooling" actually locked them into an indefinite purchase commitment, or that the factory holds the mold hostage after the relationship ends. A well-written clause prevents both outcomes.

How should the amortization amount and per-unit repayment be written into the clause?

The clause should state the total tooling cost in USD, the exact per-unit amortization fee, and the unit quantity at which the tooling is fully repaid. Look for five specific numbers before you sign: the total mold cost, the per-unit amortization fee, the total units to full repayment, the deposit timing, and a separate buyout figure.

Here is what each number does:

• Total tooling cost — the full amount the factory spent machining the mold. If the clause quotes "free tooling," it means the cost is hidden inside the unit price. Ask for the breakdown either way.
• Per-unit amortization fee — the amount added to each unit's price until the tooling is repaid. Industry-typical fees range from $0.10 to $2.00 per unit for small molded parts.
• Units to full repayment — how many units you must buy before the fee drops away. Most factories set this at 80-100% of a stated minimum purchase quantity.
• Deposit timing — when the initial tooling contribution is due. A 30% deposit at order placement and 70% before shipment is common in the category.
• Buyout figure — the price to pay off the remaining tooling balance early and gain immediate ownership. This is your escape hatch.

At LIGHT BDB, the per-unit amortization structure typically aligns with the MOQ tier you select, so a larger first order repays the tooling faster and lowers your landed unit cost sooner.

What should the clause say about tooling ownership, exclusivity, and transfer?

Ownership of the tooling should transfer to you once amortization is fully repaid, with a defined exclusivity window and a buyout option written in. Without these three elements, a factory can legally keep your mold, sell your design to another brand, or refuse to release the tooling when you switch suppliers.

Negotiate these specifics:

• Ownership transfer point — the clause should state that after full repayment, you own the mold, its drawings, cavity inserts, and any custom fixtures. You should be able to request mold drawings upon request once repaid.
• Exclusivity window — industry-typical exclusivity runs 12-24 months, during which the factory may not use your tooling for another client. After the window, many factories ask for a small annual storage fee to keep the mold in their facility.
• Transfer terms — once repaid, moving the tooling to your nominated forwarder or a new assembly partner should be allowed. Many factories charge a removal and shipping fee; the industry-typical range is 5-10% of the original tooling cost.
• Buyout option — if you want ownership before full repayment, a fair buyout is typically the remaining unamortized balance plus 10-20%, not a full repurchase at original cost.

LIGHT BDB works with your nominated forwarder and ships FOB Shenzhen, which makes tooling transfer logistically straightforward once ownership is yours.

How do LIGHT BDB's MOQ tiers interact with tooling amortization?

LIGHT BDB's MOQ tiers are Lite (100-499), Slim (500-999), and Pro (1,000+), and each tier changes how fast your tooling cost is amortized. Your tier selection determines both your unit price and how quickly the mold repayment is completed.

The Lite tier is intentionally small — 100-499 units — so you can validate demand before committing to a large amortization schedule. The Slim tier is the most popular and balances per-unit cost with a manageable commitment. The Pro tier delivers the best unit cost and unlocks full customization, because the factory can absorb design engineering across a longer run and repay the tooling faster.

Regardless of tier, LIGHT BDB's lead time stays 4-8 weeks from deposit to FOB Shenzhen for most SKUs, and samples arrive in 7-14 days with the sample fee refundable against your first purchase order.

What happens if you cancel, pause, or delay production before full amortization?

A clear clause defines a cancellation fee equal to the unamortized tooling balance, with a grace period for pauses and a re-start window for delays. Buyers rarely read this section until they need it, and it is the most negotiated part of the contract.

Push for these three protections:

• Cancellation fee formula — the clause should state that cancellation before full repayment costs you the remaining unamortized balance, not the full original tooling cost. That is the fair math.
• Pause grace period — a 30-60 day pause window, during which no unit purchase is required but the exclusivity clock keeps running. This covers you during a packaging redesign or supply-chain hiccup.
• Re-start credit — if you resume within 6-12 months, prior amortization payments should still count toward the balance. Industry-typical factories credit prior payments when a project resumes within a year.

Also check how lead-time delays are handled. If the factory quotes 4-8 weeks and misses it, the amortization clock should pause; otherwise you are paying for tooling while the factory holds up production. LIGHT BDB's standard lead time covers most SKUs within that window, so a delivery clause anchored to 4-8 weeks is realistic, not aspirational.

What contract terms and certifications should you verify alongside the amortization clause?

Verify payment terms (T/T 30/70 or L/C at sight), lead time of 4-8 weeks, and certifications such as ISO 9001, ISO 14001, BSCI, UL registered, and Sony Green Partner. The amortization clause exists inside a larger contract, and those adjacent terms determine whether the deal actually works.

Check these before signing:

• Payment terms — T/T 30/70 means 30% deposit at order placement and 70% before shipment. L/C at sight is available for letter-of-credit buyers. Both are industry-standard for ODM work.
• Shipping terms — FOB Shenzhen means your forwarder takes responsibility at the port; confirm the factory will work with your nominated forwarder, as LIGHT BDB does.
• Warranty — LIGHT BDB offers a 500-day limited warranty, which is one of the longest in the wellness-device category. Confirm how warranty claims are handled before the amortization clause takes effect.
• Certification scope — ISO 9001 covers quality management, ISO 14001 covers environmental management, BSCI (amfori) covers social compliance, and UL registered factory status plus Sony Green Partner cover factory-level safety and materials compliance.
• Category honesty — LIGHT BDB is a wellness-device ODM; its products are designed for comfort and wellness, not regulated medical use. Confirm that the factory's certifications actually match your product category before committing to custom tooling.

Honest trade-offs: what a fair amortization clause costs you and what it protects

A fair amortization clause protects your tooling investment but commits you to a minimum purchase quantity, so weigh cancellation risk against unit-cost savings. No clause is free, and the best one is the one you read twice.

The real trade-off is commitment. In exchange for a lower per-unit price and ownership of a custom mold, you accept that a failed product costs you the unamortized tooling balance. That is the deal. The alternative — buying off-the-shelf products with no tooling cost — means no customization and thinner margins.

Two more honest caveats. First, standard molds tie you to the factory until repaid, so negotiate the buyout option even if you never use it. Second, don't negotiate a clause so one-sided that the factory loses all protection; a factory with zero recourse will simply inflate your unit price to cover the risk. The goal is a clause where both sides can point to the math if the relationship ends.

LIGHT BDB mitigates the risk on its side with a 500-day warranty and refundable sample fees, so the money you spend before committing to tooling is not wasted. That is the kind of alignment a good clause formalizes.
