Commercial terms belong in writing before a large order because they are what the purchase order will be measured against later. Minimum order quantity, price basis, and lead time are the three most common causes of a stalled project. Ask for the MOQ in pieces and per part number, since a 100A option and a 200A option may not share the same threshold. Price basis should state currency, unit, packaging, and Incoterms, plus whether tooling or setup is charged once or amortized into the unit price. Lead time should be split into sample lead time and mass-production lead time, because a fast sample says little about a 10,000-piece run. Warranty scope, change control, and documentation belong in the same thread. Ask what the warranty covers—workmanship, contact resistance drift, housing damage in transit—and how a claim is handled. Ask how changes are communicated, since a resin swap, a terminal plating change, or a tooling repair can alter performance. A written change-notice clause keeps the pack builder informed. Documentation is worth naming item by item: the technical datasheet with current rating and pin assignment, a RoHS declaration, material information for the housing, and dimensional inspection records. A manufacturer that makes a performance claim should be able to provide the document behind it. The DM80 details cover 2+6 pins, 100A and 200A options, a thermoplastic housing, a UL94V-0 material rating, and battery pack use. MOQ, price, lead time, inventory, warranty, and certificates require a confirmed quote or supplier document, so put them on the list you send out.
