MOQ, OEM/ODM, certifications, lead time, payment terms and warranty — the questions B2B buyers ask us most. Still unsure? Send us an inquiry.
What is your minimum order quantity (MOQ)?
It depends on the item — typically 50 units for welding machines and 5,000 pcs for consumables; both are negotiable. If you want to evaluate first, you can order a single sample unit.
Can you produce under our own brand?
Yes. We support OEM and ODM: logo and branding, retail packaging, colour, and firmware or app customisation. Send us your artwork and target specification and we will confirm feasibility and tooling requirements.
We can also supply under your own brand, or under our house brand RIGHTEST, so you can start with a ready product line instead of creating new artwork. If you need brand assets or a distributor authorisation letter, tell us and we will confirm what we can provide.
Do the products have the certifications we need?
Our products are manufactured to meet CE, FCC and RoHS requirements, and we can request test reports, UN38.3 lithium-battery transport reports and MSDS from the manufacturers for the specific models you are considering. Certification and registration requirements differ by market, and the importer of record is responsible for confirming compliance in the destination market. Tell us which models and which market you need, and we will provide the documents we hold before you place a bulk order.
What compliance obligations apply in my market?
As the importer you are responsible for market access requirements in your country. Typical examples — EU: CE marking under the applicable directives (machinery, EMC, low voltage), RoHS, WEEE / EPR producer registration, an EU responsible person under the General Product Safety Regulation, and importer details on the label; US: California Proposition 65 warnings where applicable and any relevant CPSC requirements. We will tell you which documents we can provide for each model, and we support your testing and registration process. This is general information, not legal advice for your market.
How long is the lead time?
Sample orders: dispatched within 3–5 business days. Wholesale orders: production typically 20–35 days from deposit and artwork confirmation, plus sea transit. Final dates are confirmed in the sales contract.
Who pays for shipping and import duties?
We quote FOB or CIF. Sea freight, import duties, taxes and customs clearance in your country are the buyer’s responsibility. Sample orders are quoted with shipping included, door to door.
Can I order a sample before committing to a bulk order?
Yes — and we recommend it. The sample fee is credited against your first wholesale order.
What are the payment terms?
Wholesale: 30% deposit on order confirmation, 70% balance against copy of Bill of Lading. Samples: prepaid in full via PayPal. We accept bank transfer (T/T) and PayPal.
What is the warranty?
12 months against manufacturing defects, counted from arrival at the destination port or 15 months from the date of shipment, whichever occurs first. Spare parts are supplied with subsequent orders, and we can include a recommended spares kit with your shipment.
Can you help with spare parts and after-sales?
Yes. We can supply spare parts, consumables and technical documentation, and we will support you and your end customers on technical questions.
How do I get a price list?
Send us your target models, quantities and destination market through the inquiry form or WhatsApp, and we will send the wholesale price list and MOQ sheet within one business day.
