The US auto parts market keeps growing, and more of that spending moves online every year. For sellers, that raises two questions at once: where to list your parts, and how to manage inventory and orders across channels without losing track.
In this guide, we focus on the US market (with notes for sellers targeting Canada) and walk you through the best platforms to sell car parts online. From eBay Motors, Amazon, and Walmart to newer channels like TikTok Shop, Temu, and Shein, we’ll show you what sells there and how to start.
Why Auto Parts Are Booming Online
Americans are driving their cars longer, and older cars need more repairs and parts. The US light vehicle aftermarket is expected to grow 5.2% in 2026 and reach $500 billion by 2029, according to the Auto Care Association and MEMA forecast.
More of this spending is moving online. In 2025, US online sales of auto parts and accessories were projected at around $44.6 billion. About half of that comes from marketplaces like eBay, Amazon, and Walmart.
Shopping for parts online has also become easier. Fitment tools on major marketplaces help buyers match a part to their exact year, make, and model. Besides, prices online are often lower than in physical stores.
Sellers benefit too. You can list the same parts on several marketplaces at once, and multichannel tools let you sync inventory and pricing with your system, instead of managing each channel separately. Steady replacement demand and a large online buyer base are major reasons the category keeps growing in US e-commerce.
But what’s the best way to sell auto parts online? Where do the automotive parts buyers shop? Let’s break it down.
eBay – Still a Top Gear for Auto Sellers
Available: US (eBay Motors), Canada (eBay.ca) · Best for: used, rare, and OEM parts
Looking to sell car parts on eBay? For US sellers, it’s one of the easiest ways to reach buyers actively searching for rare, used, or OEM parts (Original Equipment Manufacturer).
eBay remains one of the best places to sell car parts online, and the numbers back it up. The marketplace counts around 136 million active buyers, and sales in its auto parts category grew faster in early 2026 than in any quarter since 2021. Demand for used, rare, and hard-to-find components is a big part of that.
Whether you want to clear out your garage or run a full-blown shop, eBay puts your parts in front of all sorts of buyers. Tail lights, mirrors, wheels, and vintage accessories for older Hondas, Subarus, or pickups sell fast, mainly OEM.
In the US, vehicle parts and accessories are sold through eBay Motors. Canadian sellers can list on eBay.ca, which has its own vehicle categories. Since American buyers often shop cross-border for parts, listing on eBay Motors is worth considering even if you’re based in Canada.
Which auto parts you can sell on eBay Motors
Here are the best-selling categories, from the top down:
- Wheels & tires;
- Exterior & body parts;
- Electrical & electronics;
- Accessories & add-ons;
- Suspension & brakes;
- Interior components;
- Tools & equipment.
A few auto-related products live outside Motors, though, in the main eBay categories:
- Car care & detailing (waxes, polishes, cleaners, brushes) > Home & Garden > Tools & Workshop Equipment > Car Care & Cleaning.
- Car electronics & gadgets (phone mounts, chargers, Bluetooth adapters) > Consumer Electronics, unless tied to vehicle fitment.
- General tools & equipment (jacks, wrenches, compressors) > Business & Industrial > Tools or Home & Garden > Tools.
- Lifestyle accessories (air fresheners, LED strips, logo keychains) > Home & Garden or Collectibles.
- Tires (in some regions) > often Home & Garden > Yard, Garden & Outdoor Living, not always under Motors.
The simple rule: if the item requires vehicle compatibility (fitment), it belongs to eBay Motors.
Get fitment right – it’s what sells
That 2018 Subaru headlamp? It can go for $120+ on eBay, while sitting ignored elsewhere. Shoppers here search by make, model, and year, and they know exactly what they’re looking for.
Use eBay’s fitment tool (Parts Compatibility) to map your parts to specific vehicles. Sellers who use fitment data get more impressions and higher conversion rates.
You don’t have to add compatibility data manually, one listing at a time. With the eBay Motors Parts Compatibility integration by M2E Cloud (for Shopify, BigCommerce, WooCommerce, and others), you can assign compatible vehicles to multiple products from your catalog at once.
The app allows you to copy fitment from an existing listing to other eBay items, or manage it in bulk via CSV. Magento (Adobe Commerce) sellers can use the M2E Pro eBay Motors extension with the same capabilities.

Extra tips for selling parts on eBay
Bundle your parts by model or year. Selling multiple items for the same vehicle, such as a set of interior trims and a center console for a 2010 Mustang, increases cart size and drives repeat purchases.
eBay is also beginner-friendly. You can create your own listing right away, and there’s no need to match your product to an existing catalog entry as on Amazon. If you want to start an auto parts business, eBay gives you the tools and traffic to grow fast.
Amazon – Big Traffic, Bigger Competition
Available: US (Amazon.com), Canada (Amazon.ca) · Best for: new, branded, fast-moving parts
Amazon is where millions of American drivers start their search for car parts. They usually search with a specific vehicle and part in mind, and they expect Prime-speed delivery, which matters a lot when the repair is urgent.
That makes Amazon strongest for fast-moving, repeat-purchase items: filters, wiper blades, bulbs, fluids, sensors, and accessories. Anything that wears out and gets replaced on a schedule fits the Amazon model well. However, if you’re selling highly technical, safety-critical, or hard-to-identify parts, Amazon may not be the best choice.
Canadian sellers have their own marketplace, Amazon.ca, which you can manage from the same Amazon account. The opportunity is smaller, though: fewer customers, more complex cross-border logistics, and higher shipping costs for buyers. In terms of scale, the US marketplace is usually the stronger channel.
Popular auto parts you can sell on Amazon
- Routine maintenance parts: air filters, oil filters, brake pads and rotors, spark plugs, wiper blades, batteries (standard & AGM).
- Engine & performance parts: ignition coils, timing belts, fuel pumps, sensors (O2, mass airflow), radiators & fans.
- Suspension & steering components: shocks and struts, control arms, ball joints, tie rod ends.
- Exterior parts & accessories: headlights & taillights, side mirrors, grilles and bumpers, license plate frames, and LED light bars.
- Interior accessories: seat covers & floor mats, dash cams, steering wheel covers, phone mounts & chargers, storage organizers.
- Tools & equipment: car jacks, socket and wrench sets, scan tools (OBD2 readers), tire inflators.
- Fluids & chemicals: engine oil, coolant, brake fluid, windshield washer fluid (Follow hazmat guidelines).
Before you start, remember to check Amazon’s policies and guidelines on selling automotive products. Amazon requires a Professional selling account for the Automotive & Powersports category, and some subcategories need approval.
What makes Amazon harder than it looks
Amazon isn’t the easiest marketplace for auto parts, and it’s worth knowing why before you sell there:
- Fitment is critical. Just like on eBay, buyers search for parts by year, make, and model. A part that doesn’t fit means a return and often a negative review. Instead of standard flat files, you must submit the compatibility data using Amazon’s Automotive Fitment Manager.
- Competition is intense. The same parts are sold by dozens of sellers, so you often compete on price alone. Make sure your margin can survive Amazon’s fees.
- Catalog work is demanding. Auto parts need accurate attributes, correct vehicle matching, and careful variation setup.
Much of that catalog work can be handled for you. M2E Cloud’s Amazon integration allows you to list auto parts on Amazon, using the catalog you’ve already built in your store.
You can map your existing catalog data to Amazon attributes and reuse it automatically for your listings. M2E Cloud also helps validate your products against Amazon’s requirements so you can publish accurate auto parts listings from the start.
Selling with Magento 2 (Adobe Commerce)? Try M2E Pro Magento Amazon extension.
If you’re new to Amazon, you can get a special offer. Register on Amazon and enjoy a 30-day free trial of M2E Amazon Integration for M2E Pro users and M2E Cloud users.
Extra tips for selling parts on Amazon
Start with a small catalog of everyday parts that are light, easy to ship, and unlikely to be returned. For example, it can be filters, wipers, or interior accessories rather than bumpers and fluids. Make sure the fitment data on those first listings is clean, and invest in strong product content. Clear photos, technical specs, and OEM cross-references help buyers trust the listing.
Once your return and conversion rates look healthy, expand into adjacent parts. As you add heavier or bulkier items, recheck the shipping math, especially for Canadian orders.

Walmart – Mainstream Reach, OEM Trust
Available: US, Canada · Best for: new and OEM-grade parts and accessories
Walmart is the most American marketplace on this list. Millions of customers trust it for everyday shopping, and that trust extends to its online marketplace. For sellers of new, branded, or OEM-grade auto parts, that’s the main advantage.
Walmart has two more points in its favor. There are no monthly or setup fees, so you pay only when you sell, which makes it a low-risk channel to test. And in many auto categories, it’s less crowded than Amazon. Fewer competing listings mean better visibility and more potential sales.
What auto parts sell best on Walmart
Walmart shoppers are everyday car owners looking for practical parts:
- Replacement parts;
- Tires and wheels;
- Accessories;
- Tools and equipment;
- Performance parts.
Before you plan your assortment, check Walmart’s prohibited products policy for auto and motor vehicles. Also, note that Walmart Canada applies stricter rules on top, with motor vehicles prohibited and some parts categories restricted.
Listing discipline matters on Walmart just like on any other marketplace. Every product needs a GTIN. Fitment data and competitive pricing decide whether you show up in search.
M2E Cloud Walmart Integration connects your Shopify, BigCommerce, WooCommerce, etc. store to Walmart so you don’t have to manage auto parts listings fully by hand. The integration keeps your listings, inventory, and prices synced with your store, so the data Walmart requires stays accurate without manual updates.
Magento store owners can use the Walmart extension by M2E Pro.

Extra tips for selling parts on Walmart
Start with parts that are easy to identify and less likely to be returned, such as filters, wiper blades, floor mats, or other common accessories. Once your listings and fulfillment run smoothly, you can add heavier items and parts that depend on precise fitment.
Overall, Walmart is a reliable channel, and it works especially well as a second or third marketplace after eBay or Amazon. It can help reach more buyers without adding monthly platform fees.

TikTok Shop – Where Views Turn into Sales
Available: US · Best for: visual, easy-to-install accessories
TikTok Shop works differently from every other marketplace in this article. If you’re wondering how to sell spare parts on a platform where nobody searches for them, that’s the place. On TikTok, buyers discover parts they didn’t know they wanted, through short videos, live demos, and creator content. That makes it a discovery channel first and a storefront second.
An installation clip or a before-and-after video can explain a part faster than any product description and put it in front of thousands of viewers who never typed a search query.
What parts sell best on TikTok Shop
Products that show well on camera: LED lights and light bars, floor mats and trim, phone mounts, organizers, cleaning and detailing products, and other easy-to-install accessories. If the result is visible in a 30-second video, it can be sold on TikTok Shop.
Hard technical components are a different story. Safety-critical parts, complex mechanical items, and anything with a high return risk are more difficult to sell through short-form videos. Buyers need more evidence than a TikTok clip can provide, especially for expensive or branded parts.
What to know before you start
- Fitment matters. If a part only fits certain vehicles, say so clearly in every listing description and caption. Vague compatibility claims confuse buyers and can increase returns.
- Some auto parts need approval. TikTok requires documentation for certain automotive categories through its Seller Center. You may also be required to pass category qualification.
- Content is the real work. Success takes frequent videos, clear hooks, and consistent testing. The selling doesn’t stop after the listings go live on TikTok.
The less time you spend on managing listings, the more you have for content. That’s where M2E Cloud’s listing automation helps. With TikTok Shop integration, you can publish products from your store catalog on TikTok. Features like category and attribute mapping cut the time spent on listing details as the app matches your catalog product data to TikTok’s requirements.
And if you already sell auto parts on eBay, Amazon, or Walmart, M2E Cloud allows you to copy these listings to TikTok Shop. You can also run TikTok Shop promotions and ads from your store’s admin, while inventory and orders stay in sync automatically. This way, your time and effort go into videos, not routine tasks.
Managing a Magento 2 store? You can try TikTok Adobe Commerce integration by M2E.
Extra tips for selling parts on TikTok Shop
Start with accessories that are easy to show. Film simple problem-solution videos (the pain point, the part, the installation, the result) and see how your audience engages with them. On TikTok, product-market fit shows up in views and comments first, and only then sales.
TikTok Shop won’t replace eBay or Amazon as the best place to sell car parts online. But as an impulse-sales channel alongside them, it’s hard to beat. TikTok Shop is great for attention and brand-building, as long as your visuals are sharp and your fitment info is clear.

Temu – Fast-Growing Reach for Auto Accessories
Available: US · Best for: value-priced accessories and styling parts
Temu has become one of the fastest-growing shopping apps in the US, and its buyers respond quickly to products with visual appeal. For auto sellers, that makes it an interesting channel for accessories: items that look good in a photo and don’t need a long explanation to sell.
Temu is also one of the easier marketplaces to start on, which makes it a good place to test new products. If an accessory performs well here, that means it can be just as successful on your other channels.
Which auto parts you can sell on Temu
Accessories and styling parts lead the way: trim pieces, seat and steering wheel covers, decals, organizers, floor mats, LED add-ons, and other cosmetic upgrades. Buyers here shop by look and price, so products with strong photos and simple appeal perform best. Bundles with car accessories may perform well on Temu.
As for more technical parts, they aren’t as popular since Temu buyers mostly come for accessories, not brake components. But if you already sell these parts on eBay or Amazon, you have everything Temu needs: descriptions, compatibility data, and the documentation Temu may request for regulated categories. With few technical sellers on Temu, your parts will have less competition than on the big marketplaces.
M2E Cloud helps with moving your listings to the new channel. The Temu integration makes it easy to start selling from your e-commerce platform (Shopify, BigCommerce, WooCommerce, etc.) thanks to automated tools and features:
- Copy your existing eBay, Amazon, or Walmart listings to Temu
- Publish products from your store with category and attribute mapping matching your catalog data to Temu’s requirements
- Run Temu promotions from your store’s admin
- Keep inventory and orders in sync between your store and marketplace
Magento sellers are welcome to try the Adobe Commerce Temu integration by M2E Connect.
If you are new to Temu Marketplace, you can receive a 30-day free trial of M2E Temu Integration for M2E Connect users and M2E Cloud users.
Extra tips for selling parts on Temu
Start with low-risk accessories (trim, covers, decals, organizers) and treat the first months as a test. Track what sells, what items get more returns, and what accessories buyers ask about. If a product or a bundle does well on Temu, bring it to your other channels.
That’s the best way to sell auto parts online: let one marketplace show you what items work, then expand them to the rest.

Shein Marketplace – Fresh Channel for Car Accessories
Available: US · Best for: lifestyle and interior car accessories
Shein built its name on fashion but now goes well beyond apparel, including auto categories. Its shoppers make quick, visual decisions, and they bring the same style-first mindset to car products. Shein Marketplace is a place where a seat cover sells because of how it looks, not its part number.
There are no monthly fees on Shein, advertising is free, and payouts come fast. However, it’s hard to qualify as a seller. The Shein US marketplace currently requires sellers to be US-based businesses that ship domestically and have at least $5 million in annual revenue.
Which auto parts you can sell on Shein
Top sellers include:
- Hanging air fresheners;
- License plate frames with slogans or LED lights;
- Car trash bins;
- Seatbelt clips;
- Backseat storage organizers;
- Pet car seat covers;
- Aesthetic dashboard decorations.
Strong photos and clear dimensions matter more here than technical specs. Shoppers decide fast and buy what they can picture in their own car.
Heavy or technical parts are a poor match. Shein isn’t built for compatibility-heavy products, and there’s no deep fitment structure to present them properly. Overall, Shein works best for inexpensive products that sell quickly, while your core business stays on eBay, Amazon, or Walmart.
If you’re ready to try Shein, adding it to the list of your sales channels takes less setup than you’d expect. M2E Cloud Shein integration helps publish products from your Shopify, BigCommerce, WooCommerce, etc. store on Shein Marketplace, match your catalog data to Shein’s categories and attributes, and keep inventory and orders in sync.
Adobe Commerce (Magento) sellers are welcome to try the Shein Magento integration by M2E.
Register as a seller on Shein Marketplace and get a 30-day free trial of M2E Shein Integration for M2E Connect and M2E Cloud users.
Extra tips for selling parts on Shein
When it comes to how to sell spare parts on Shein, the assortment matters more than anything. Begin with a small set of visual, interior accessories and watch how they perform. With no monthly fees, testing items on Shein costs little and lets you experiment.

What It Costs: Marketplace Fees for Auto Parts
Fees decide your margins on auto parts, and they’re rarely one flat percentage. On a $200 brake kit, the difference between a 12% and a 15% referral fee is $6, which is enough to matter when you compete on price.
Rates change by category and account type, so treat the numbers below as a starting point. Also, check each marketplace’s current fee page before pricing your items.
| Marketplace | Fees | What you should know |
| eBay | ~13.6% | Rates vary by category |
| Amazon | 15% up to $300, 8% above $300 + $39.99/month | Professional plan is required for Automotive & Powersports category |
| Walmart | 12% referral fee | Flat rate for Automotive & Powersports; no monthly or setup fee |
| TikTok Shop | Varies by category and program | No published rates for the automotive category. Check your seller account’s fee page |
| Temu | No fees for product listing | Learn more |
| Shein Marketplace | Up to ~10% referral fee | No monthly fee; the rate depends on category |
Summary
There’s no single best way to sell auto parts online. The question is which channel to start with, and which to add next. Want to sell used, rare, or OEM parts? Start on eBay. New, fast-moving replacement parts? Amazon, if your fitment data is clean. Then add Walmart for its lower fees and lighter competition, and TikTok Shop, Temu, or Shein for accessories that sell on looks.
Beyond these, you can sell auto parts on Mirakl-powered marketplaces, from distributor-led platforms like Driven Brands to retail channels like Best Buy and Lowe’s. We’ll cover them in a separate article.
Most sellers end up running two or three channels from one catalog. Keeping listings, stock, and prices aligned across all of them is where M2E Cloud comes in. Connect Shopify, BigCommerce, WooCommerce, or another platform, and sell on all these marketplaces from one place. Magento sellers can use M2E Pro.
