Substance Regulations

Japan RoHS (J-MOSS) Compliance

Find the six specified substances across your BOM so you can mark each product correctly under Japan's J-MOSS standard, with the content data behind every declaration.

The six specified substances, found across your BOM

J-MOSS asks you to disclose six substances through a green or orange mark on seven product categories. Compliance Manager finds them per part and supplies the content data, so here is what you get.

How Z2 helps

/1

Out-of-the-box coverage

Most of your BOM assessed for the six J-MOSS substances on day one from Z2's FMD and CoC database.

/2

Compliance status

Each part returned Affected, Not Affected, or Noncompliant.

/3

Item rollup

Substance presence at every level of the product hierarchy.

/4

Compliance evidence package

The per-part content behind a green or orange mark, ready to download.

/5

Supplier outreach

Z2-led campaigns collect the FMDs and CoCs you're missing.

/6

Monitoring and alerts

Notified when the JIS C 0950 standard is revised.

BOM assessment

Find the Six Specified Substances

Load a BOM and every part is checked for the six substances J-MOSS covers.

  • Each part returned as Affected, Not Affected, or Noncompliant.
  • Strong day-one coverage from Z2's FMD and CoC database.
  • Assessed alongside your EU RoHS and REACH work in the same pass.

Content data

The Data Behind Each Mark

J-MOSS is a disclosure regime, so each result carries the substance content used to justify the mark.

  • Per-part content drawn from declarations in Z2's database.
  • The presence and location of any substance above the limit made clear.
  • Gaps in supplier data closed through Z2-led outreach.

How J-MOSS works

A Disclosure Mark, Not a Ban

J-MOSS requires products to declare substance presence through a mark rather than prohibiting it.

  • Six substances are specified: lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE.
  • A green mark shows a product is under the limits; an orange mark discloses a substance above them.
  • The requirement applies to seven consumer product categories.

One platform

Part of Z2 Compliance Manager

J-MOSS is one of 270-plus regulations Compliance Manager runs on a single BOM.

  • Assessed next to EU RoHS, China RoHS, REACH, and your wider program.
  • Item rollup shows substance presence up through the product hierarchy.
  • Z2's in-house materials scientist tracks JIS revisions.

Common Questions

How does Z2 handle J-MOSS's disclosure model?

J-MOSS (JIS C 0950) requires covered products to disclose six specified substances through a mark rather than ban them: a green mark when the product is under the limits, an orange mark with a content table when a substance sits above them, across seven consumer product categories. Compliance Manager assesses each part against the six substances and shows where any sits above the limit, which is the input that determines the mark.

Which substances does Z2 assess for J-MOSS?

Six: lead, mercury, cadmium, hexavalent chromium, and the PBB and PBDE flame retardants, each assessed at the homogeneous-material level against the 0.1% weight limit (0.01% for cadmium).

How does Z2 help me choose the green or orange mark?

Compliance Manager assesses each part for the six substances and shows where any sits above the limit, which is the status that determines the mark and the content table, so your marking decision rests on the underlying material data.

How does J-MOSS fit with the rest of my compliance program in Z2?

J-MOSS runs on the same BOM as more than 270 regulations in Compliance Manager, evaluated alongside EU RoHS, China RoHS, and REACH, with item rollup across the product hierarchy.
