Door Hinges OEM/ODM Handbook for Interior Fit-Out Firms: the 2026 season Guide No.709

For Switzerland, door hinges are a steady, replenishable line, and getting the sourcing right decides whether the category is profitable or a returns headache. This guide for Interior Fit-Out Firms sets out what to check, what to ask and what to document before you place an order.

Choosing the Right Supplier

Ask the factory how many door hinges lines it runs and whether your order shares a line with another buyer. Check how the factory handles subcontracting, because hidden sub-lines are the most common cause of inconsistent quality. Confirm who owns the moulds, the artwork and the tooling, especially if you intend to reorder the same design next season. Visit or video-audit the line; a five-minute walk-through reveals more than a page of certificates.

Materials and Construction

For door hinges, the construction matters as much as the material: watch the knuckle fit and screw countersink. A good door hinge starts with the cold-rolled steel or stainless with pins, so agree the material grade before you discuss price. Ask to see how the product looks after it has been used for a week, not only on the day it leaves the factory.

Planning the Production Calendar

Standard production for door hinges runs 30 to 60 days after sample approval, so build the calendar from the approval date. Keep a second qualified factory on file, because a single-source season carries avoidable risk. Review the schedule weekly against actual output, not against the original promise. Split large programmes into two or three deliveries so that early stores are fed and later stores are not overstocked. Build a buffer of seven to ten days between the ex-factory date and the sailing date for the unexpected.

Cost and Price Structure

Freight, duty and inland handling can add more than the factory price difference, so compare landed cost, not FOB. Most price gaps between quotations come from a different material grade or a thinner finish, not from factory margin. The price of door hinges breaks down into material, labour, finishing, packing and margin, and only some of those move with volume. Watch the raw material index and the energy surcharge, because both move the cost of door hinges during a long programme.

Compliance and Certification

Ask for social compliance documentation such as a BSCI, Sedex or WRAP audit dated within the last twelve months. Chemical and packaging rules differ by market, so confirm the destination requirements before you finalise the packing spec. Confirm that the test house is accredited and that the report names your product, not a generic specimen. Request test reports for restricted substances and, where relevant, product safety standards for the destination market.

Quality Control

Test the product the way a customer would use it, because laboratory conditions hide the failures that matter. Insist on a pre-shipment inspection against an AQL plan, with the report sent to you before the goods leave. Book an in-line inspection at 30 percent completion: that is the cheapest moment to fix a problem. Photograph the inspection, the packing and the pallet; images settle most disputes faster than documents.

Five Boxes to Tick Before You Order

Specification signed, sample approved, inspection booked, packing confirmed, documents ready. Tick these five boxes and your door hinges shipment will most likely arrive as planned.
