How RoHS and REACH Compliance Affect Your Metal Material Selection Process

If a purchase order has ever come back because your material failed a compliance check, you know the cost. It’s not just the material. It’s the schedule, the customer conversation, and the documentation scramble that follows. Getting ahead of RoHS and REACH starts with your bar stock supplier.

At Precision Ground Metals in Palos Hills, IL, we’ve sourced and supplied compliant ferrous and non-ferrous materials for over 30 years. Compliance isn’t something we add at the end. It travels with every order we process, so your procurement team isn’t left chasing paperwork when your customer asks for it. Our customers come back because we’re a dependable supplier, not just a catalog.

What RoHS and REACH Mean for the Materials You Specify

Both regulations shape which grades you can use and what documentation you need to provide downstream. RoHS restricts specific hazardous substances in electrical and electronic equipment. REACH covers substances of very great concern across the full supply chain. Either one can create a compliance gap if your supplier isn’t prepared to back their material with proper disclosure documentation.

The good news is that compliance doesn’t eliminate your material options. It focuses them. Knowing which grades are straightforward to document and which require closer attention lets you make smarter decisions earlier in the process. That’s where working with a supplier who maintains RoHS and REACH compliance on every order makes a real difference.

RoHS and Lead Content in Free-Machining Alloys

Every grade we supply is tailored to your exact application needs, whether that’s a precision-ground shaft for a Swiss machine or a compliance-ready bar for a defense assembly. The most common RoHS conversation we have involves lead in free-machining brass. C360 Free-Machining Brass contains 3% lead, which gives it excellent machinability for precision components and valves. If your finished product ships into a RoHS-regulated market, that lead content needs to be disclosed and documented before production starts, not after a rejection.

C360 isn’t automatically off the table. Your supplier needs to confirm what’s in the material and provide the right documentation to support it. If C360 does create a compliance problem for your specific application, we also stock C260 Cartridge Brass and C230 Red Brass. Both are available in precision-ground form when dimensional accuracy and composition both matter.

REACH and Substance Disclosure Across Your Supply Chain

REACH doesn’t just apply to finished goods. It covers substances of very great concern at every level of the supply chain. When your customer requests a substance disclosure or declaration of compliance, that request flows back to your material supplier. If your supplier isn’t prepared, you’re the one absorbing the delay.

We supply most of our materials from domestic sources and maintain REACH compliance, so your team gets clean documentation without a lengthy back-and-forth. Certain alloying elements present in tool steel grades like D2 and H13, and alloy steels like 4140 and 4340, fall under REACH monitoring. Sourcing from a compliant supplier closes that documentation gap before your auditor finds it.

How Compliance Affects Stainless Steel and Aluminum Selection

Stainless steel is often a strong choice in compliance-sensitive applications. Our precision-ground stainless bars cover austenitic grades 303, 304/304L, 316/316L, 321, and 310/310S, ferritic grades 430 and 409, martensitic grades 410, 420, and 440C, duplex grades 2205 and 2507 Super Duplex, and 17-4 PH. Austenitic grades generally avoid the substance concerns most flagged under RoHS and REACH.

Aluminum is another low-friction path through compliance review. Grades 6061 and 7075 are our most common requests from aerospace, medical, and robotics customers. Our precision-ground aluminum bars hold tolerances within ±0.001 inch. The alloy family tends to avoid the substance concerns that complicate compliance conversations in leaded or heavily alloyed materials.

DFARS: The Third Compliance Layer for Defense Suppliers

If your work touches defense contracts, DFARS domestic sourcing requirements apply on top of RoHS and REACH. Managing all three from a single supplier simplifies your procurement significantly. Most of the materials we supply are domestically made, which positions us to support DFARS requirements directly without sourcing exceptions.

Defense and aerospace buyers frequently face all three frameworks on the same order. Stainless grades like 316/316L and 17-4 PH, aluminum grades 6061 and 7075, and our full alloy steel range, including 4140 and 4340, are all available with compliance documentation. Getting material, documentation, and dimensional precision from one source reduces the number of conversations your team has to manage.

Tolerances Are Not Affected by Compliance Scope

Compliance documentation doesn’t change what a precision-ground bar delivers dimensionally. Our stainless steel precision-ground bars hold h6, h7, and h8 tolerance classes with surface finishes of Ra 0.2 to 0.8 µm. Alloy and carbon steel precision-ground bars hold ±0.0005 inch or better. Tool steel precision-ground bars hold ±0.001 inch or better.

Dimensional precision and compliance travel together on every order we ship from Palos Hills. Whether you’re running Swiss machines, linear motion components, or precision shafts, the bar stock performs to spec. Your documentation is ready for your customer before they ask for it.

Get Compliant Bar Stock With the Documentation Your Team Needs

Precision in Every Shape & Size is more than a tagline for us. It means every bar we ship meets your dimensional and compliance requirements together. Quality is our top priority on every order, and that includes the documentation that travels with your material.

Every order can also include straightening, chamfering bar ends, cutting to length, protective packaging, and reliable shipping so your material arrives ready to run. On-time delivery is essential to how we operate, and we build it into every order we cut, package, and ship from Palos Hills.

Frequently Asked Questions

Does RoHS or REACH limit which grades I can order?

Not always. It may influence grade selection with leaded alloys like C360 Brass. We stock compliant alternatives and can discuss substitutions based on your application requirements.

Do you provide RoHS and REACH documentation with orders?

Yes. Specify your compliance requirements in the quote form notes field. We include the documentation your procurement team needs with every applicable order.

Does DFARS apply to our project?

If you supply a prime or sub-tier defense contractor, it almost certainly applies. Most of our materials are domestically sourced to support DFARS requirements directly.

Which grades do you stock for compliance-sensitive applications?

Stainless grades 304/304L, 316/316L, 17-4 PH, aluminum 6061 and 7075, copper C10100 and C11000, and full alloy, carbon, and tool steel ranges. All available with compliance documentation.
