The 5000-piece MOQ hits harder if you're only prototyping or running a small batch, so we usually suggest ordering samples first to test fit and finish — we've had some folks order the full quantty and then realize teh 360° rotation isn't what they needed for a fixed-angle cabinet door, and that's on them, not us.

What it does well is hold up over time with that iron construction and electroplating or painting finish, so for high-traffic furniture like kitchen cabinets or wardrobes where the hinge gets opened and closed constantly, it's actually reliable — we run HPLC and salt spray tests to catch corrosion issues early, typically 72 hours in the chamber, and we'll share the COA with your order.

Anyway, the 4x3 standdard size fits most European-style hinge cups, but if your board thickness is off, you might need to shim it — we include a retest policy if the first batch doesn't meet spec, just return the unused units within 30 days (check lead time though, as at 500,000 pieces monthly and we book up fast).
It's not suited for outdoor furniture or high-moisture environments unless you specify the painted finish, and even then, we'd recommend stainless instead — but for indoor use, the ten years of normal operation, and most buyers go with the electroplated version for the smoother look.

Packging is 50 per box, 2000 per carton, and our company can customize logo or color if you order 10,000 pieces or so — the HS code is 8311300000, which usually clears customs without issues, but confirm your local duties because we don't track that for you.
You can pick either electroplating or painting depending on your finish preference. We can mix treatments across different batch orders, just let us know the quantities for each option.
Yes, the 10-year warranty covers all JFSD-ALH1004 hinges regardless of customization—logo, color, or packaging changes don't affect it. It's tied to the hinge's iron material and 360° rotation mechanism.
We generally stick to 5000 pieces as the minimum, but for first-time buyers we can sometimes do a sample order of a few hundred pieces. That won't get the custom packaging or logo, but you'll get the standard 50PC/box packaging to test the hinge.
Standard production takes about 15-20 working days for 5000 pieces. Custom logo printing adds roughly 3-5 days to that, depending on the complexity. Our monthly capacity is 500,000 pieces, so we can scale up fast if needed.
Sure, we can provide a material composition report and a surface treatment certificate (electroplating or painting) upon request. For bulk orders, we also include a quality inspection report with each shipment.
