MARKET / JAPAN
Brown Fused Alumina Supplier for Japan
Documented, batch-tested brown fused alumina for Japanese abrasive makers and surface preparation users, with inspection carried out against the specification agreed for each order.
WHAT JAPANESE BUYERS ASK FOR
Documentation and repeatability come first
Japanese buyers typically open with the paperwork: the grading standard, the chemistry limits, and how each lot is verified. Our standard production and inspection follow the FEPA F and P grading systems. If your acceptance documents work to a different standard, send them with the inquiry — production and inspection for your order are then carried out against the standard agreed between us, and that agreement is what the batch is released against.
Every shipment travels with its own batch test report, and retained samples are kept so any later question can be checked against the material that actually left our plant.

What a Japanese order usually looks like
If an element limit matters to your process — iron, silicon, titanium or another value — name it in the inquiry. Different furnace types give different chemistry bands, and the matching band is selected for your specification.
SHIPPING & DOCUMENTS
From Luoyang to Japanese ports
Containers load at Tianjin or Qingdao, a short crossing to the main Japanese gateways: Yokohama and Tokyo for the Kanto region, Kobe and Osaka for Kansai, and Nagoya for the Chubu industrial belt. Quotations are available FOB or CIF.
WHY CHAOYAN
Process control behind the paperwork
Luoyang Naibao has worked in brown fused alumina since 1999; the CHAOYAN trademark was registered in 2014, and combined supply capacity is about 80,000 tonnes a year. Fixed and tilting furnaces, roller crushing and air classification give us control over chemistry, grain shape and grading — the three things your acceptance inspection will measure.
