FREE basic specification and sourcing-requirements review
Eligible first orders may receive up to 3%
Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements. Final savings depend on supplier confirmation, product type and order value.
US business buyers only. Factory quotes stay subject to named-supplier confirmation.
Uneven replies
One factory quotes a unit price on nitrile. Another quotes FKM, a different inner diameter, or a different Incoterm. The gap is not a market saving.
automotive rubber grommets on one basis
Compare factory replies for automotive rubber grommets only when compound, size, quantity, packing and documents match. Rubber Grommets Sourcing does not publish a discount calculator.
Same-basis checklist, not a savings engine
Use this layout to see which quoted scope differences explain a price gap. Tick a row only when both offers answer it. The form does not compute a percentage and does not promise a lower total.
Situation cards for reading a gap
Compound swap
NBR quoted against FKM on a body-panel pass-through is not a courtesy upgrade. Thermoplastic elastomer samples also are not a drop-in for vulcanized rubber when the buyer asked for compression set at engine-bay heat. Re-issue the line with the compound and ASTM D2000 callout visible.
Size drift
If the request named a 0.375 inch inner diameter and the offer names a neighbouring size, the substitution has to be written down before anyone talks about money.
Specification move
A change in Shore A, panel thickness or destination state is a new request. Keep the original approved line on file so later lots can be compared.
Send both offers with the original request
This desk will not recast an Incoterm or compound change as a percentage saving. Eligibility for any sourcing support is confirmed after product, quantity, destination and requirements are reviewed.
