TSCA 6(h) Article Exemptions: What the EPA Really Says

Clarifying the Myth of TSCA Section 6(h) Around "Articles"

When the U.S. Environmental Protection Agency (EPA) finalized restrictions under TSCA Section 6(h), many manufacturers assumed they were unaffected because they only deal with "articles," not chemicals. It’s a common and costly misunderstanding.

TSCA does not provide a blanket exemption for articles. In fact, depending on how a PBT substance is used in or on an article, and whether exposure can reasonably occur, the exemption may not apply at all.

Let’s break down what the EPA actually says—and what manufacturers need to know.

What Qualifies as an "Article" Under TSCA Section 6(h)?

According to EPA guidance, an article is a manufactured item:

• That is formed to a specific shape or design during production
• Has end-use functions dependent on that shape or design
• And does not release or result in exposure to a chemical substance under normal conditions of use

Examples include:

• Insulated wires
• Circuit boards
• Molded plastic housings
• Fasteners, brackets, enclosures

But simply meeting this definition does not automatically exempt an item from TSCA Section 6(h).

TSCA Section 6(h): When Articles Are Still Regulated

TSCA Section 6(h) covers five PBT substances, including PIP (3:1) and DecaBDE, which are commonly used in electronics, wiring, and plastic components.

If a PBT substance is:

• Intentionally added to the article, and
• Can result in exposure to humans or the environment

…then TSCA 6(h) restrictions likely apply—even if the item is an article.

The EPA clarified this position in response to industry pushback when finalizing its 2021 and 2024 rule updates. (See: EPA PBT Final Rule Update October 2024)

Common Misconceptions of TSCA Section 6(h)

Myth: Articles are exempt from all TSCA chemical restrictions.

Reality: Articles are not exempt when they intentionally contain a listed PBT and exposure is possible.

Myth: Coated parts are excluded.

Reality: If the coating contains a regulated PBT (e.g., PIP 3:1), and that coating could result in exposure (e.g., during handling or disposal), the rule applies.

Myth: "We buy components, we don’t make them"—so we're not responsible.

Reality: Importers and downstream users are responsible for ensuring compliance.

Industry Examples: When Articles Trigger TSCA Section 6(h))

• Wire harnesses using insulation that contains PIP 3:1
• Plastic enclosures flame-retardant-treated with DecaBDE
• Connectors that use rubber parts formulated with PCTP

If these components are imported, processed, or distributed in the U.S. without valid exemptions, they fall under TSCA Section 6(h).

What Manufacturers Must Do

1. Don’t assume article exemption applies. Evaluate whether the article:
   • Contains a PBT
   • Was formulated with intentional use
   • Could result in exposure
2. Request supplier declarations identifying:
   • PBT content
   • CAS numbers
   • Intended use
   • Exemption status
3. Screen BOMs for TSCA PBT CAS numbers and assess exposure risk
4. Review exemption criteria carefully, especially for:
   • Articles in contact with humans
   • Workplace exposure scenarios
   • Articles disposed as hazardous waste

Don’t Forget Section 12(b): TSCA Export Notifications

If you export articles containing a PBT listed under Section 6(h), you may also be subject to TSCA Section 12(b) export notification requirements. These apply even if the article is exempt from commercial restrictions domestically.

Tools to Make This Easier

Platforms like Acquis help automate:

• Screening of BOMs and part libraries for PBT risk
• Collection of supplier declarations with article-level detail
• Documentation of exemption justifications and audit trails

Reflection

The EPA is clear: Being an article isn’t a free pass. What matters is how the PBT substance is used—and whether exposure is possible. For manufacturers, that means being proactive, not passive.
