A backpack issued for the 2008 Beijing Olympics was reported still in use at the 2026 Aichi-Nagoya Asian Games, 18 years later. Fabric specification alone does not explain that service life. Soft cases fail first at five load-transfer points, and four of the five are fixed before tooling is cut.

Material plus labour does not explain a custom protective case quotation. Most of the cost sits in five engineering decisions taken before the first unit exists: how tight the cavity tolerance has to be, how many functional layers the material stack needs, whether the interior is formed in one piece or assembled by hand, what the tool is made of, and how much compliance testing the destination market requires. This note sets out what each variable changes in the quotation, where buyers pay for tolerance they do not need, and what to put in the RFQ so that two quotations can be compared on the same footing.

Social compliance audits are won and lost on documents, not on the shop floor. Before you commit to a protective case supplier, request the full audit report with its scope page, the open corrective action list, three reconciled weeks of wage and attendance records, and a written subcontracting declaration. If the site address on the report is not the site making your goods, the report does not cover your order.

Where the weeks go in a custom protective case programme: the four blocks from requirement to production, how concurrent engineering overlaps them, and the three points where FZ® recovers time.

How the OEM, ODM and JDM models differ for custom protective cases, where each one fails, and how product maturity should decide which model to buy: DFM review, design ownership and prototype quantity.

Why a low purchase price can raise maintenance spend: the TCO formula for custom protective cases, the lifecycle costs that never appear in a quotation, and how replacement interval drives cost per operating hour.

Two numbers decide whether a custom protective case programme survives R&D: the minimum order quantity, and the tooling charge that resets with every design change. This note shows how a tiered MOQ structure removes that fixed cost.

FZ® shares 10 practical sourcing pitfalls industrial buyers should avoid when procuring custom protective cases — from sample gaps to COA traceability.
