FAQ
Q: Do your middle back mesh chairs comply with European and North American safety standards?
A: Yes. Our chairs are fully certified under ANSI/BIFMA X5.1 (USA) and EN 1335 (Europe) for commercial structural safety and durability. Official test reports issued by SGS or TÜV are available upon request.
Q: What is your standard Minimum Order Quantity (MOQ)?
A: Our standard MOQ is 50 units for standard stocking configurations. For custom mesh colors, OEM private labeling, or custom box artwork, the MOQ is 200 units per model.
Q: How does your sample fee refund policy work?
A: Samples take 5–7 working days to build. While sample costs and freight are paid upfront, 100% of the sample fee is credited back to your account once your first formal container order is placed.
Q: How many units can fit into a 40' HQ container?
A: Thanks to our high-density Knocked-Down (KD) packaging design, we can load up to 700 units into a standard 40' HQ container, significantly reducing your sea freight cost per unit.
Q: What is your average production lead time for a 40HQ container?
A: Mass-production lead time is 25 to 30 calendar days following deposit confirmation and artwork sign-off.
Q: How do you ensure the backrest mesh doesn't sag after long-term commercial use?
A: We use high-tension polyester-nylon matrix mesh installed with automated pneumatic stretch machinery. The mesh undergoes 50,000+ Martindale fatigue cycles in our lab to guarantee long-term surface tension stability.
Q: What warranty coverage do you offer on commercial bulk orders?
A: We provide a 5-year structural warranty (frame, base, tilt chassis) and a 3-year component warranty (gas lift, casters, mesh upholstery) under standard commercial office operating conditions.
Q: What are your accepted payment terms and trade terms?
A: We support FOB, CFR, CIF, and DDP trade terms. Standard payment terms are T/T (30% deposit upfront, 70% balance against Bill of Lading copy) or irrevocable L/C at sight for large volume contracts.
