Questions procurement asks
- Which grades are suitable for ductile iron in Japan?
- Buyers often start with ZW01 or ZW02 when they need higher fixed carbon and lower listed nitrogen (100–200 ppm on the sheet). Confirm the contractual nitrogen ceiling in writing.
- Can Jiushun match Japanese particle-size preferences?
- Listed sizes include 0–2 mm, 1–5 mm, 3–5 mm and 5–8 mm. Other ranges are available when stated on the order.
- How do Japan buyers enquire?
- Send company, grade, size, quantity and destination port via the contact form, email sales@jiushuncarbon.com, or WhatsApp. We reply the next business day (UTC+8).
