Frequent questions

Before you write.

A few things people ask most often. If your question isn't here, just send it — we'd rather answer than have you guess.

Do you ship parts internationally?

Yes — we regularly ship to Taiwan, China, Japan, Singapore, the US and the EU. We handle export documentation; the customer typically handles import duties.

What's a typical lead time on in-stock parts?

3–5 business days from order confirmation for items marked "In stock" on the Product page. Refurbishment programs vary by scope — typically 6–14 weeks.

Do you offer warranty on refurbished tools?

Yes. Refurbished tools come with a standard 6-month parts warranty plus on-site support during the qualification period. Extended terms available on request.

Can you support tools not listed on the Business page?

Sometimes. We focus on Canon, TEL/DNS and AMAT — but adjacent systems (LAM, Nikon, ASML) come up regularly through our parts network. Ask and we'll tell you straight.
