Question 1

How do you keep mass production consistent with the approved sample?

Accepted Answer

The approved sample is paired with a controlled specification or BOM. SONGJU records agreed materials, critical dimensions, finish, marking, packaging, inspection points, and permitted substitutions. Changes require review instead of silent replacement.

Question 2

What quality checks are performed before shipment?

Accepted Answer

Checks are selected by product risk and buyer requirements. Typical controls include dimensions, operation, drive fit, ratchet direction, joint movement, edge or face condition, marking, piece count, case retention, labels, carton quantity, and visual workmanship.

Question 3

Which certifications does SONGJU currently publish?

Accepted Answer

Certification and compliance documents are confirmed against the exact model, supply scope, and destination market. If your program requires ISO, IEC, VDE, CE, RoHS, REACH, or third-party test evidence, provide the market, model, and required document so SONGJU can confirm applicable evidence and availability.

Question 4

Can material or inspection reports be supplied?

Accepted Answer

Yes, when defined before quotation. Available evidence depends on the item and may include material declarations from the approved source, dimensional or functional inspection summaries, hardness records, torque verification data, packing lists, and retained-sample records.

Question 5

How are engineering or packaging changes handled after order confirmation?

Accepted Answer

A requested change is reviewed for price, MOQ, schedule, tooling, obsolete material, and inspection impact. Production proceeds only after the relevant drawing, BOM, sample, or artwork revision is approved by the responsible parties.
