Japan's lower duty (15.05% vs 27.05%) lets it price up to 10.4% above China at the factory and still match on duty-inclusive customs cost. But on the LATEST measured prices, China actually lands cheaper — $22.83/kg vs $26.62/kg (duty in, freight out).
12 Chapter-99 measures name Japan; scope mapping is partial (several annexes are PDFs) — absence never means exemption. They do not sum, and some are product-specific — the collected rate above is the composed truth.
