Sample policy, MOQ, lead time<\/strong> \u2014 these three procurement levers decide whether a transformer or cable accessory order ships on schedule: sample policy (the terms under which a supplier provides a physical sample), MOQ (minimum order quantity, the smallest batch a factory will produce), and lead time (the total interval from confirmed order to shipment).<\/p>\n\n\n\n

Late clarification is the most common cause of stalled accessory procurement. A buyer locks a project timeline against a quoted lead time, then discovers the figure excluded the sample-approval loop or assumed a quantity above the actual MOQ. The order returns to engineering for re-quotation, and a two-week RFQ cycle stretches toward six. On a substation package with eight or ten line items spanning bushings, fuses, and cold-shrink kits, every unconfirmed parameter compounds the risk.<\/p>\n\n\n\n

What matters most is how the three levers interact, not any single value. A favorable unit price loses meaning if the MOQ sits at 500 pieces when the project needs 60. A short headline lead time misleads if sample approval adds three to four weeks on top. In field experience, the orders that energize on schedule are the ones where sample terms, batch minimums, and stage-by-stage lead time were fixed in writing on the proforma invoice. The same discipline governs both product systems, the transformer accessories range<\/a> of bushings, tap changers and fuse assemblies, and the cable accessories range<\/a> of cold-shrink and heat-shrink terminations and joints. Custom-configured items in either family follow different sample, MOQ, and lead-time logic than standard catalog SKUs, which is exactly why the questions below belong at the front of the conversation.<\/p>\n\n\n\n

Sample Policy: What to Clarify Early<\/h2>\n\n\n\n

A sample request feels routine, but the terms attached to it shape both cost and schedule. The core questions are who pays, how long the sample takes, and whether it genuinely represents the bulk run.<\/p>\n\n\n\n

Paid vs. free sample conditions and credit-back terms<\/h3>\n\n\n\n

Suppliers handle sample cost according to the item’s value and tooling needs. Low-value standard parts are sometimes free, with the buyer covering only freight. Higher-value or custom-configured items, a molded medium-voltage bushing, a non-standard fuse assembly, usually carry a sample charge that may be credited back against a later bulk order above a stated quantity. Confirm the credit-back threshold and whether courier freight (often 30\u201380 USD per small parcel) and import duty fall to you, since ambiguity here is a frequent source of post-shipment disputes.<\/p>\n\n\n\n

Sample lead time vs. bulk lead time<\/h3>\n\n\n\n

These are separate numbers, and conflating them distorts planning. An in-stock standard sample may dispatch within 2\u20135 business days, while a custom sample requiring a short tooling or casting run can take 2\u20133 weeks before it even ships. Ask explicitly whether sample preparation and bulk production run in parallel after approval, or whether bulk only starts once the sample is signed off, that single distinction can move the final delivery date by weeks.<\/p>\n\n\n\n

Ensuring sample-to-production spec parity<\/h3>\n\n\n\n

The most consequential clarification is parity. On one project, a 15\/25 kV medium-voltage bushing sample arrived with a different terminal stud configuration than the production drawing specified, because it came from existing stock rather than the quoted build. Confirm in writing that the sample’s voltage class, current rating, creepage distance, material grade, and terminal interface are identical to the production item and that it carries the same routine-test basis the bulk order will.<\/p>\n\n\n\n
