Overview

J-MOSS is Japan's marking standard for chemical substances in electronics, set out in JIS C 0950. It does not ban anything. It tells a buyer, through a simple mark, whether specified substances sit below or above set thresholds in a product.

Key point

J-MOSS is a marking rule, not a ban. A green mark means content stays below the thresholds. An orange mark means a substance is over the limit and a content table must follow.

How the marking works

The standard covers the same six substances as the original RoHS. For each product, the question is whether any of these substances exceeds its threshold.

Green mark
All specified substances stay below the thresholds. No content table is required.
Orange mark
At least one substance is above its limit. The product must carry a content table showing where it occurs.

The content table behind an orange mark gives detail by part of the product, so a reader can see which component holds the substance above the threshold.

How it relates to other topics

  • The six substances come straight from the original RoHS.
  • A side-by-side view of these regimes sits in the regulation comparison.
  • chemSHERPA is the Japanese scheme for passing the underlying substance data along the supply chain.
