Recycled materials in cars? Many people instinctively ask: Will OEMs agree?

The reality is: it's not about whether it's possible, it's a must. The EU ELV New Regulation (EU) 2026/1738 is already in black and white—by 2032, new models should have at least 15% recycled plastic, and by 2036, at least 25%.

Even more magical, the threshold for automotive-grade recycled nylon is even stricter than many virgin materials.

This article explains the label of "automotive-grade" thoroughly: why it's so expensive, how can it be obtained, and where the sources of materials are reliable?

The ceiling for recycled nylon is the cap: automotive-grade.

Wear it, and you can enter OEMs; If you can't, you can only make industrial and daily goods.

Once you put on this hat, the price of materials will go up a whole level—because behind it is a whole certification system, not just cleaning thoroughly.

Regulations are the biggest driving force

Half of the demand for automotive-grade recycled materials comes from regulations.

EU 2026/17 38: After September 1, 2028, for newly certified vehicles, the proportion of plastic recycled in the vehicle must be no less than 15% (effective from September 1, 2032); From 2036, it will be raised to 25%, with at least 20% of that must come from closed-loop recycling of end-of-life vehicles.

Although there is no one-size-fits-all mandatory ratio domestically, leading automakers have already taken action: SAIC, BYD, and CATL have set the procurement threshold for recycled nylon 6 at no less than 15% by mass.

What does this mean? It means that "automotive-grade" recycled nylon is not optional; it is a threshold that all materials wishing to enter the supply chain must overcome in the next five years.

The threshold for OEMs is higher than the regulations .

The law sets a lower limit, and OEMs set an upper limit.

Automotive-grade recycled nylon must pass three stages: performance — tensile, impact, temperature resistance, oil resistance, benchmarked item by application; Odor level—Odor level must be kept below level 3, low VOC is a hard requirement, and the engine bay must smell the same as new material; Traceability level—Every raw material, every additive, and every batch of recycled material must be entered into the IMDS system based on molecular formula and mass ratio. If one data error is made, the entire form is sent back for re-review, and a delay can take two to three weeks.

Starting in 2026, new models are increasingly required to have recycled material in key nylon components at least 10%—not because they want to use it, but because policy forces it.

That's why "automotive-grade" is expensive because of the system: certification, traceability, every batch of testing, stable supply—all of which cost money.

Closed-loop recycling: The hard constraint on turning scrap cars into new ones

The strictest rule is closed-loop recycling.

Starting in 2036, at least 20% of recycled plastics must come from scrapped vehicles for dismantling and recycling—that is, a "car-to-car" closed loop, rather than downgrading car waste elsewhere.

This means the source of automotive-grade recycled nylon should go toward "dismantled parts": nylon parts from end-of-life vehicles (intake manifolds, fans, wiring harness connectors) are removed, sorted, re-pelletized, and then returned to new vehicles.

The biggest bottleneck in this closed loop is sorting—scrapped nylon parts are mixed in variety and have inconsistent glass fiber content, resulting in insufficient sorting precision and poor recycled material quality. Whoever can properly dismantle and sort will be choked by the future supply of automotive-grade materials.

Material Supply Assurance: Why is direct sourcing from Southeast Asia key

Automotive-grade sources are scarce, making import channels a lifeline.

Vietnam, Thailand, and Malaysia are important suppliers of recycled nylon materials: Ho Chi Minh City, Vietnam, has customized modification factories for PA and PP recycled pellets serving the world; Bangkok, Thailand, has a PA66 recycled pellet manufacturer supplying hundreds of tons per month; Malaysia has a manufacturer producing PA66 automotive airbag resin recycling lines, with a single base capacity of about 12,000 tons per year.

For those selecting recycled nylon, the value of these imported materials is not cheap, but "stability"—PIR sprue material has a single composition, controllable heat history, and multi-country direct sourcing capabilities to ensure each batch has viscosity, ash content, and fiberglass balance.

Ningbo Cologne has built a material supply network in Southeast Asia for years, with direct sourcing from Vietnam, Thailand, and Malaysia. In short, the "traceability" of automotive-grade materials is established from the source—each material comes from a source, which batch, and what indicators are all known.

In conclusion: Five steps to certification clearance

1. Look at regulations: 15% in 2032 and 25% in 2036 are not long-term slogans, but supply chain red lines;

2. Check performance: benchmark item by application, don't just use a universal report to fool the senses;

3. Check odor: odor level below level 3, low VOC, and odor in the engine compartment;

4. Check traceability: IMDS data is complete, and can samples be kept for each batch;

5. Check the material source: whether there are stable channels and supplier qualifications for direct procurement in multiple countries, and whether a closed loop can be maintained.

In conclusion: Why is automotive-grade recycled nylon so expensive? It lies in regulations, systems, and material sources. Ningbo Kolong New Materials Co., Ltd. has been providing automotive-grade recycled nylon material sources and certification support for many years, from direct sourcing in Southeast Asia to IMDS traceability assistance. In short, it's about knocking on every door you enter the OEM factory in advance
