What is counterfeiting?

According to the International Trademark Association:

A counterfeit is an unauthorized replica of a product or an imitation of something authentic. The counterfeiting of electronic components is big business—and the effects can be costly and potentially harmful or deadly. At Partstack we're committed to protecting our user community from the negative effects of counterfeiting.

Mixed parts

Mixing "good" parts with "bad" parts and selling as all good parts, or mixing lower specification parts with high specification parts and selling as all high specification parts.

Fraudulent sales

Selling low specification "low-spec" parts and making them look like high specification “high-spec” parts.

Being used parts

Selling used, repaired, or refurbished parts as “new” or “new and original” products.

At Partstack, we're committed to authentic purchasing experiences

How in-house testing labs can benefit

Testing is an expensive investment in equipment, materials, and qualified operators for distributors. Smaller distributors will typically outsource testing to third-party test labs. Larger independent distributors may employ their own lab facility as a value-add to reduce costs and shipping time to you.

Testing hybrid model

Many distributors use a hybrid model for testing where some tests are performed in-house and more advanced testing is performed at a third-party lab if required by your purchase order. All methods are valid. You'll need to decide which option works best for your needs.

types of testing
Common types of testing

Visual inspection

Compares your parts to a known good sample (when available) and to the part's datasheet.

Detailed visual inspection

This testing is typically performed with a high-powered microscope and other tools.

X-ray inspection

Goes to the heart of the device to ensure internal bond wires are in place and the die is intact.

Resurfacing testing

Uses chemicals to test the ink markings and paint adherence on the parts.

Electrical testing

Ensures that the part’s electrical characteristics match the manufacturer’s specifications on the datasheet.

And many others!

You can always ask Partstack sellers which testing options they provide or recommend.

Collaborative efforts

Counterfeiting requires work and input from everyone. If we all do our part, counterfeiters will have a harder time moving and passing off their fraudulent goods.

What we're doing?

What we're doing?

To maintain the integrity of our user community and trading platform, Partstack will investigate all reported instances of potential suspect/counterfeit part listings appearing on the site, and may, at its own discretion, conduct investigations without having received a formal report.

Any user that is determined to have engaged in the sale or offering of counterfeit material on Partstack.com or any digital PPP, will be immediately suspended and reported to the manufacturer and other relevant authorities.

We're helping our community identify suppliers with a great industry track record, in-house testing capabilities, and other positive indicators that reduce the chance of knowingly or unknowingly selling counterfeit material.

We are working on advanced algorithmic tools and inventory monitoring ai to suppress certain listings from our supplier stack.

What you can do?

What you can do?

While this may not always be possible, it is the absolute best way to ensure that the parts you receive are authentic. Not only can you assure that your parts are not counterfeit, you'll also be able to tap into warranties, help/support desks, and other resources the manufacturer may offer its customers.

If the manufacturer does not have what you need, look for authorized distributors. These are distributors that the manufacturers have partnered with to sell their products. They may also be able to offer product support and pass along warranties from the manufacturer should you run into an issue down the road.

Last (but not least!), check with other market distributors — but do your due diligence. At Partstack we promote market transparency so that great “indies” can shine. The best of the best will have:

Quality certifications

Choose distributors with third-party quality certifications like ISO 9001, AS9120, and AS6081. These certifications indicate annual inspections by an unaffiliated quality-auditing agency, ensuring reliability.

Testing capability

Look for distributors with in-house testing capability, as this indicates a commitment to internal quality. Reputable suppliers will gladly provide sample test reports or equipment lists to earn your trust. For added assurance, choose a distributor whose lab is included in a quality certification's scope or carries its own certification.
