How much deposit should renting and sharing cases take?

Answer: 1.2–1.5 times case value, per unit rather than per batch — RMB 960–1200 on a case worth RMB 800. Above 1.5 times, clients drift toward purchase, so pair the number with a ten-day refund window.

How is cleaning priced?

Answer: 8–15 per case against six minutes and four steps, water below 40 °C. Standing water, salt on the latch seats and solvent-lifted print cause most rejections.

When does a scratch become chargeable?

Answer: Beyond 0.5 mm deep, at 30 per square decimetre. A broken latch bills 35, a gasket strip 28, and a cracked body settles at 60%–80% of depreciated value.

How long should turnaround be?

Answer: 7–21 days by job type — 7–10 for inspection rounds, 10–14 for trade shows, 14–21 for cross-region work. Overrun bills at 1.5 times daily.

What count variance is acceptable?

Answer: 1%. In a pool of 1000, counting 990 is normal; trace the shortfall through transit, then stop lending for a week.

Renting and Sharing Cases: Deposit and Wear

Quick answer: Renting and sharing cases runs on three settings: deposit at 1.2–1.5 times value, six minutes of cleaning per return, and a 0.5 mm scratch waiver.

FAQ

1. Setting the deposit

A case worth RMB 800 takes an RMB 960–1200 deposit, or 1.2–1.5 times its value. That band is two exposures added up. Loss is the first: a vanished case settles at depreciated value, so a deposit below replacement cost leaves a hole. Heavy repair is the second, and a full latch set, a gasket and a body patch can pass 120 on one unit. At 1.2 times the formula covers both; 1.5 times holds room for collection and payment terms.

More deposit is not more safety. At twice the case value, the client's finance team reclassifies the order from rental to purchase. Settle the refund window first — ten working days after acceptance — and the number agrees itself.

Charge per unit, never per batch. When 120 cases come back in three shipments, refund forty at a time, or the first two stay locked until the third lands.

The deposit is right or wrong on the day it is refunded.

2. Rate structure and turnaround

Daily rent runs 1.5%–3% of case value, so a case worth RMB 800 bills RMB 12–24 a day. Past five consecutive days most operators switch to a weekly rate counted as 4.5 days, handing a small discount to short high-frequency work. Quote both; a daily figure alone invites the client to multiply by thirty and reach a number nobody charges.

Item	Basis	Note
Deposit	1.2–1.5 times value, per unit	Refunded 10 working days after acceptance
Daily rate	1.5%–3% of value	Part of a day counts as one day
Weekly rate	4.5 days	Quoted beside the daily rate
Cleaning	8–15 per case	Billed once at return
Overrun	1.5 times the daily rate	Starts after the turnaround ceiling

Turnaround sits between 7 and 21 days and follows the job: inspection rounds 7–10, trade shows 10–14, cross-region projects 14–21. It also sets fleet size — with 200 cases, a 10-day cycle and three uses a month, about 60 are in circulation and the rest are dispatchable stock. Leave the cycle unwritten and scheduling happens by phone.

One clause sits beyond the ceiling: overrun bills at 1.5 times the daily rate. It exists to bring cases back, not to earn. Most lost efficiency in renting and sharing cases hides inside the phrase "two more days".

3. Cleaning in six minutes

Cleaning bills at 8–15 per case against six minutes of labour, and four steps fit: strip removable parts, 1 minute; rinse at ambient temperature, 2 minutes; wipe the gasket groove and latch seats, 2 minutes; dry and rack, 1 minute. The goal is acceptance — one grain of grit in the groove fails the next pressure test.

Keep water below 40 °C. Polypropylene softens above 60 °C and thin walls take a permanent set, while a heated gasket swells and sits 0.3 mm proud of its groove.

Three faults cause nearly every rejection: water standing in the groove, salt on the latch seats, and silkscreen lifted by solvent. The first two yield to a cloth and a low-pressure lance; the third needs a different cleaner, because ketone and chlorinated solvents bloom the print.

Every case passes a visual check before it goes back on the shelf: no standing water, no crystallised salt, no residual odour. Fail any of the three and it returns to step two.

4. Inspection and wear bands

Inspection happens on the return day with six photographs: one per corner, the sealing face, the nameplate. The pictures are your baseline, not the client's evidence — three returns of the same case show whether a scratch is spreading. Nine disputes in ten in renting and sharing cases come down to whether a mark was there last time.

Band	Condition	Settlement
1	Scratch 0.5 mm deep or less	Waived, logged in history
2	Scratch deeper than 0.5 mm, or print lost	30 per square decimetre
3	Latch broken, gasket flat, body cracked	35 per latch, 28 per strip, 60%–80% of depreciated value

Inside band 3 the contract needs one sentence: a cracked body is not repaired, it settles at depreciated value and the case becomes the lessor's property. Loss follows the same band at 60%–80%, straight-line over five years, so a case in its third year settles at 40% of original.

The damage baseline is 2%–5%. Out of 100 cases in one cycle, two to five arriving with visible marks is ordinary wear; above 5%, check turnaround intensity and packing before discussing money. In renting and sharing cases the bands discipline use rather than generate revenue, and saying so in the preamble beats saying it after the table.

Why 0.5 mm and not 0.2 or 1.0? Marks under 0.2 mm appear within a week of handling, so charging for them turns every return into an argument; past 1.0 mm they catch a fingernail, and waiving those costs real money. Half a millimetre is the line both sides accept.

5. Nine clauses and a count variance

Nine clauses carry the agreement: deposit, term, rate and overrun, cleaning, acceptance, wear bands, loss, stock count, disputes. Everything else belongs in an annex; the shorter the body, the faster it gets signed.

Count stock quarterly with a 1% tolerance. In a pool of 1000 cases, counting 990 is normal — trace the ten through transit and the repair bay, then book them as lost after two working days. Above 1%, the ledger has drifted from the floor, and a week off-rent beats another month of lending.

A clause with no matching field on the acceptance form does not exist.

Conclusion

The operating rules of renting and sharing cases reduce to three settings. Deposit at 1.2–1.5 times value, per unit, refunded in ten working days. Cleaning at 8–15 a case, six minutes, water under 40 °C. Wear in three bands — 0.5 mm waived, 30 per square decimetre, then 35 a latch, 28 a gasket, cracked bodies at 60%–80% — inside a 2%–5% damage baseline and a 1% count tolerance. Put them into nine clauses, tie them to six photographs, and the return day stops having a second version of the truth.
