Services

How we support your production

Beyond supplying parts, we take over the coordination work that slows down purchasing and production teams.

BOM

BOM One-Stop Sourcing

Send a full bill of materials and receive a consolidated quotation covering every line — availability, price, alternative options and delivery. One order, one invoice, one shipment.

STK

In-Stock & Shortage Supply

Fast-moving lines are held in stock in Shenzhen. For urgent production stoppages we prioritise finding available stock and confirming it before quoting.

ALT

Alternative & Cross-Reference

When a part is obsolete or has a long lead time, we propose cross-referenced alternatives with datasheet comparison for your engineering team to approve.

QC

Incoming Inspection

Brand, part number, date code and packaging are checked before dispatch. Documentation is provided with the shipment on request.

KIT

Kitting for SMT Lines

Components for a production run are consolidated and labelled by line item, so the material can go straight to the assembly floor.

SHP

Export Packing & Shipping

ESD-safe packaging, export cartons and documentation, with express or air freight to your factory or nominated forwarder.

Ordering process

  • Step 1 — Inquiry. Send a BOM (Excel/CSV), a list of part numbers, or a description of the shortage you need resolved.
  • Step 2 — Quotation. We reply in writing with manufacturer, part number, quantity, unit price, packaging, stock status and estimated dispatch date.
  • Step 3 — Confirmation. You approve the quotation; the order is documented before payment, including any approved alternatives.
  • Step 4 — Dispatch. Goods are picked, inspected, packed and shipped with tracking information and commercial documentation.

We supply businesses and manufacturers. Minimum order quantities vary by part; please state your target quantity in the inquiry for the most accurate pricing.

What to include in your inquiry

  • Manufacturer part number (MPN) and brand if specified
  • Quantity required, and whether partial shipment is acceptable
  • Target date the parts are needed on your line
  • Any packaging requirement — reel, tube, tray, cut tape
  • Whether alternatives are acceptable for out-of-stock lines
