When harness factory purchasers send fixture inquiries to overseas suppliers, unstandardized RFQ details and ambiguous contract terms always lead to unexpected extra cost, delayed delivery or poor-quality finished jigs after production. This problem frequently happens among buyers from Mexico, Brazil and Paraguay, especially small & medium maquila workshops with limited sourcing experience. Many hidden overcharging and quality loopholes are set in vague quotation clauses, resulting in 20%~40% unexpected extra spending later.<\/p>\n\n\n\n

This practical RFQ guide sorts out the most common quotation traps and standardized inquiry rules, helping buyers complete accurate quotation comparison and cut unnecessary hidden expenses.<\/p>\n\n\n\n

1. Top 6 Hidden Quotation Traps in Fixture Procurement<\/strong><\/p>\n\n\n\n

1.1 Quotation excludes accessory & vulnerable part cost<\/strong><\/p>\n\n\n\n

Some suppliers quote low base fixture price deliberately, while positioning clips, replacement probes, fixing stoppers are listed as separate extra-charge items after order confirmation. It is the most common trick for South America small-batch orders, which finally raises overall procurement budget obviously.<\/p>\n\n\n\n

1.2 Separate design drawing & engineering charge<\/strong><\/p>\n\n\n\n

Several factories do not mark engineering cost on initial quotation. After confirming sample development, they charge extra CAD design fee, programming cost and fixture layout expense. Especially for complex test fixtures used in Mexican Tier1 production lines, hidden design cost is easy to exceed budget.<\/p>\n\n\n\n

1.3 Ambiguous material specification switching without notice<\/strong><\/p>\n\n\n\n

Quotation marks anti-static 12mm bakelite or standard 6063 aluminum, but replace with thinner non-antistatic sheet or recycled aluminum during production to cut cost. The finished fixture appears quick deformation and fails ESD workshop inspection.<\/p>\n\n\n\n

1.4 Shipping & custom document split additional cost<\/strong><\/p>\n\n\n\n

Initial quotation only counts product price, excluding export documents, plywood package fee, customs certificate and inland delivery from factory to port. Extra logistics expense pops up before shipment, commonly seen in Paraguay and Africa low-cost fixture orders.<\/p>\n\n\n\n

1.5 Unclear after-sales scope, spare parts all charged separately<\/strong><\/p>\n\n\n\n

Quotation does not specify free spare wear parts quantity and after-sale technical support. Once probes or positioning blocks wear out after arriving at destination, suppliers ask full payment for replacement accessories.<\/p>\n\n\n\n

1.6 Tolerance standard not fixed on contract<\/strong><\/p>\n\n\n\n

No written dimension tolerance requirement in RFQ and contract. Manufacturers produce fixtures with loose tolerance to reduce processing difficulty, causing positioning deviation after on-site installation and unable to meet OEM production standard.<\/p>\n\n\n\n
