In July 2026, the Civil Aviation Administration of China (CAAC) made global headlines by publishing the first official compliance directory for manned eVTOL manufacturers, naming EHang, XPeng AeroHT, Volant Aerotech, and AutoFlight (Fengfei) as the inaugural batch of companies eligible for accelerated type certification. The message was clear: China’s low-altitude aviation industry is no longer a collection of flying prototypes — it is a regulated, commercializing sector where credentials matter more than press releases.

For international buyers evaluating a Chinese drone or eVTOL supplier, investors screening a potential portfolio company, or law firms advising on cross-border aviation transactions, this is both good news and a warning. The good news: a clear certification framework now exists. The warning: marketing claims in this sector routinely outpace regulatory reality. A company may have flown a dramatic demo at an airshow, but that tells you nothing about whether its aircraft are legally permitted to carry paying passengers, whether its production line meets quality standards, or whether the entity you are contracting with is even the same legal person that holds the certificates.

This guide walks you through the practical verification steps that separate legitimate operators from companies that look impressive on a brochure but would collapse under due diligence. We will decode the CAAC certificate maze, explain how to cross-check a company’s claims against official Chinese government databases, and identify the red flags that should make you pause before wiring a deposit.

1. Why Verification Is Non-Negotiable in China’s Aviation Sector

Unlike consumer electronics or general merchandise, where a sample order can quickly tell you whether a supplier is real, aviation products carry irreversible safety, regulatory, and financial consequences if due diligence is skipped. Three factors make verification uniquely urgent in China’s low-altitude sector right now:

First, the certification race has created powerful incentives to overstate progress. A single press release announcing “TC accepted” can move stock prices or unlock venture funding, but “accepted” merely means the CAAC has agreed to review the application — it is not an approval, and the average TC review cycle for a manned eVTOL still takes 2–3 years. We have encountered multiple companies that present an “acceptance notice” as if it were a type certificate in marketing materials targeted at foreign buyers.

Second, complex group structures can obscure who actually holds what. Many eVTOL companies use holding companies, operating subsidiaries, and special-purpose vehicles in different cities. A certificate may be held by a subsidiary, while your purchase contract is signed with a parent or affiliate that lacks operational authority. Tracing these relationships requires access to China’s official enterprise registry data, not just a company’s English-language website.

Third, foreign recognition of Chinese certificates is still uneven. The CAAC’s type certificates are not automatically recognized by the FAA or EASA. If you plan to operate or resell a Chinese-built aircraft outside China, you must verify whether bilateral airworthiness agreements cover the specific model and category — a question that goes far beyond the manufacturer’s assurances.

2. Decoding the Four Certificates: TC, PC, AC & OC

Before you can verify a company, you need to understand what each certificate actually authorizes. Chinese aviation regulation follows a sequential four-certificate model, and holding one does not imply holding the others.

As of September 2026, only EHang’s EH216-S holds all four certificates globally — TC, PC, AC, and OC — enabling it to legally carry paying passengers on commercial routes. AutoFlight’s V2000CG cargo eVTOL holds TC, PC, and AC (the world’s first certified eVTOL above one ton takeoff weight) but has not yet been issued an OC for commercial cargo. All other Chinese manned eVTOL developers remain somewhere in the TC application pipeline.

3. Step 1 — Corporate Registry & Shareholder Verification

Before you evaluate an aircraft, verify the entity. Many international disputes with Chinese suppliers ultimately trace back to one simple failure: the buyer contracted with a different legal entity than the one that owned the assets, certifications, or intellectual property they thought they were buying.

Start by obtaining an official enterprise credit report from the National Enterprise Credit Information Publicity System (NECIPS) or, for deeper analysis, a professionally compiled business credit report. At minimum, verify the following:

• Unified Social Credit Code: Confirm the company’s 18-digit code matches the one on any certificates, contracts, or invoices. Discrepancies here are an immediate red flag.
• Registration status: The company should show as “存续” (active / existing). Watch for “注销” (cancelled), “吊销” (revoked), or “迁入/迁出” (relocation in progress) statuses.
• Registered capital: A low registered capital figure (e.g., under RMB 10 million for an aircraft manufacturer) relative to claimed operations may suggest a shell entity. Note that under China’s subscribed capital system, registered capital is not the same as paid-in capital — a paid-in capital check reveals how much shareholders have actually contributed.
• Shareholder structure & actual controller: Identify the ultimate beneficial owner (UBO). Aviation is a sector with foreign ownership restrictions; if a foreign entity is shown as a controlling shareholder in a manned eVTOL operator, verify that necessary approvals are in place.
• Business scope: The registered business scope (经营范围) must explicitly include “民用航空器制造” (civil aircraft manufacturing), “民用航空器运营” (civil aircraft operations), or relevant categories. A company registered only for “technology development” or “import/export” may not legally manufacture or operate aircraft.
• Historical changes: Frequent changes in legal representative, registered address, or shareholders within a short period can signal instability, restructurings, or attempts to shed liabilities.

A standard enterprise credit report will give you the fundamentals; for aviation transactions, we recommend upgrading to a professional-tier report that traces equity penetration through multiple holding layers, identifies related-party transactions, and cross-references key personnel across affiliated entities.

4. Step 2 — Intellectual Property & Patent Landscape Checks

In the eVTOL and drone industry, intellectual property is the moat. A company that lacks core patents in its own name — particularly in flight control algorithms, electric propulsion systems, battery thermal management, or vertical takeoff-and-landing mechanisms — is likely an assembler rather than a technology developer, with obvious implications for after-sales support, spare parts supply, and product iteration.

Key questions to answer through a patent search:

• Volume vs. quality: How many invention patents (发明专利) does the company hold, as opposed to utility models (实用新型) or design patents (外观设计)? Invention patents undergo substantive examination and are a far stronger signal of genuine R&D capability.
• Technology coverage: Are patents concentrated in the company’s declared core technology? For example, a company claiming expertise in tilt-rotor architecture should have filings specifically covering tilt mechanisms, not just general drone frame structures.
• Inventor team: Are the named inventors consistent with the company’s claimed technical leadership? A mismatch — e.g., key patents filed by founders who have since left — can indicate brain drain.
• Licensing-in vs. ownership: Are core patents owned by the company, or exclusively licensed from a university, research institute, or third party? Dependence on licensed-in technology introduces continuity risk.
• Geographic coverage: Patents filed only in China offer no protection if you plan to operate or resell the aircraft internationally. Check for PCT international filings or filings in your target market.

Patent searches in China can be conducted through the China National Intellectual Property Administration (CNIPA) database, but English-language interfaces are limited and classification can be opaque. A dedicated IP verification report, mapped to the company’s product architecture, is often a worthwhile investment before signing a technology partnership or distribution agreement.

5. Step 3 — Red Flags: Administrative Penalties & Litigation Risks

Even well-funded, well-certified companies can carry hidden liabilities. Chinese government databases publish a range of enforcement records that should be screened before any transaction:

6. Step 4 — Deep-Dive Signals: Bidding Records, Social Insurance & Investments

Beyond basic corporate records, three data points offer a far more honest picture of a company’s actual operational capacity than any pitch deck:

Government and SOE bidding records (招投标记录). In China, state-owned enterprises, government agencies, and public institutions are required to publish tender and award notices publicly. Winning bids from organizations like the State Grid, China Post, or local public security bureaus is a strong validation signal: these buyers conduct their own rigorous qualification reviews. Conversely, a company that claims massive commercial deployment but shows up in zero public bidding records may be overstating its traction.

Social insurance contribution headcount (社保缴纳人数). Companies in China must disclose how many employees are covered under their mandatory social insurance registration. While this figure is not a perfect headcount (it may exclude contractors or employees at subsidiaries in other cities), it is one of the hardest-to-fake indicators of real team size. A company claiming 500 engineers but showing only 30 insured employees is almost certainly inflating its scale. For eVTOL developers, expect to see several hundred insured employees at the TC stage, reflecting the large engineering, flight test, and quality teams required.

Outbound investments and subsidiaries (对外投资). Tracing a company’s investment portfolio reveals its strategic footprint: where its production bases actually are, whether it has established operating subsidiaries in low-altitude pilot zones (Shenzhen, Hefei, Guangzhou, Chengdu), and whether it has spun off any entities that hold key certificates separately. This is also how you detect “license parking” arrangements where a certificate held by one entity is used to market services offered by an unrelated entity.

7. Your Actionable Due Diligence Checklist

The table below summarizes the verification steps, the data sources, and what to look for at each stage. Use it as a working checklist when evaluating any Chinese drone or eVTOL counterparty.

China’s low-altitude aviation market is moving faster than any comparable market in history, and that speed creates both extraordinary opportunity and extraordinary information asymmetry. The difference between a successful partnership and a costly mistake rarely lies in the quality of the demo flight; it lies in whether you have verified that the entity, the certificates, the intellectual property, and the people you are counting on are everything they claim to be.

As the market matures through 2026 and 2027 — with an estimated 5–10 additional eVTOL models projected to receive type certificates, and cargo drone networks scaling across dozens of Chinese cities — the window for easy, unvetted deals is closing. Buyers and investors who approach this sector with the same rigor they would apply to any highly regulated aerospace supply relationship will be the ones who capture the upside without the surprises.
