An estimate is not a formal quote

Unknown hardware, incomplete unfolded dimensions or missing processes prevent a complete estimate. An engineer resolves these before publishing a formal quote.

Engineering review

Estimates are indicative USD amounts converted with a daily-checked USD/CNY reference rate calculated from same-date ECB data. A formal quote requires engineering review and a confirmed currency snapshot. Shipping, taxes, special packaging and full product assembly are outside the standard scope.

The 12% gross margin applies only to qualifying confirmed batches of 50+ fabricated parts. Samples and small batches retain their stated cost multipliers. No unapproved contingency is added.
