Importing diamond tools from China takes 60–90 days end to end: 1–2 weeks to source and sample, 3–5 weeks to produce, 4–6 weeks by sea to most of the world. Typical process is: request samples and test, place a 30% deposit, approve pre-production samples, factory produces, pre-shipment inspection, balance payment, ocean freight, customs clearance, and last-mile delivery. Diamond tools are not dangerous goods and ship freely by sea or air.
List 3–5 factories. Compare them on the criteria in our vetting guide. Ask each for samples of the exact SKUs you plan to stock. Do not skip this — the sample test decides everything.
Send a written purchase specification: product, diameter, arbor, segment height, bond, quantity, packaging, and delivery port. Get the factory to quote against it in writing. This becomes your contract.
Standard terms: 30% T/T deposit, 70% balance against copy of bill of lading. Ask for a proforma invoice that lists bank details, HS code, and INCOTERM (FOB Shenzhen/Yantian is common for southern China factories).
At JOY TECH, our range of diamond saw blades and core bits ships FOB Xiamen, a deep-water port with direct sailings to North America, Europe, the Middle East, and Southeast Asia.
Production takes 25–35 days after deposit. Ask for weekly photo updates. Before shipment, do or commission a pre-shipment inspection. The balance is only paid once you are happy with the inspection report.
| Method | Cost | Time | Best for |
|---|---|---|---|
| Express (DHL/FedEx) | High | 3–7 days | Samples, small urgent orders |
| Air freight | Medium | 7–12 days | High-value small orders |
| LCL sea | Low | 25–35 days | Trial orders under 5 CBM |
| FCL sea (20GP/40HQ) | Lowest per unit | 30–45 days | Repeat container orders |
Have your forwarder handle customs. You will need: commercial invoice, packing list, bill of lading, and certificate of origin. Typical duties on diamond tools are 0–8% depending on HS code and your trade agreements. Budget 5–10% of goods value for duty plus clearance.
Importing is as much a cash flow exercise as a logistics one. Budget three money moments: the 30% deposit at order, the 70% balance against bill of lading, and duty plus freight collect at destination. For a USD 10,000 order, you need roughly USD 13,000 available over the 60-day cycle. Do not commit your last dollar to the deposit — leave margin for unexpected delays, port storage, or a third-party inspection. Once you have three repeat orders under your belt, you can negotiate better terms and predict the cycle. For the first order, pick a product you know will sell rather than experimenting with five new SKUs.
For first-time importers, a forwarder who specializes in China-to-your-country lanes is worth every dollar. They book the ship, handle customs, and call you when documents are missing. Ask other importers in your industry who they use — a forwarder familiar with diamond tools will know the HS code and any local duty quirks. For LCL shipments, the forwarder consolidates your goods with others; for FCL, they book a whole container. Expect to pay USD 150–300 for LCL and USD 1,500–3,000 for a 20 ft container to the US West Coast. Budget another 10% for customs clearance and drayage.
Keep digital copies of every shipping document in a cloud folder: invoice, packing list, B/L, and inspection report. When customs asks for a document two years later, you will have it. Paper files in a drawer get lost; cloud files do not.
Keep your supplier's lead time in writing on the PO. If they say 30 days, hold them to it. A delay beyond seven days should come with a reason and a new ETA, not silence.
Once the first container lands and you have cleared customs without surprises, the whole process becomes much easier. The second order is smoother because you already know the documents, the forwarder, and the port.
A: No. They are metal goods with no chemicals, batteries, or powders. They ship as general cargo.
Common codes are 6804.22 (agglomerated diamond tools). Confirm with your customs broker, as rates vary by country.
A: Yes, DDP terms are available from most forwarders. They cost more but remove customs hassle for first-time importers.
Buy marine insurance (around 0.3% of cargo value). Claims are processed against the bill of lading.
Importing from China is a predictable process once you have a reliable factory. The hard part is the first 90 days; repeat orders then flow every 45 days. Contact JOY TECH for a proforma invoice and freight estimate to your port.
