High-Tech Enterprise
💰 Significantly Reduced Tax Costs This is the most direct and widespread benefit. The corporate income tax rate is reduced from the statutory 25% to 15%. This means that, for the same level of profit, companies can retain more funds for growth. In addition, there are several cumulative benefits: Extended Carryforward Period for Losses: Unrecovered losses from the five years prior to the year in which a company qualifies as a high-tech enterprise may be carried forward, with the maximum carryforward period extended from 5 to 10 years. This effectively helps smooth out early-stage R&D losses for technology companies. Additional Deduction for R&D Expenses: R&D expenses can be deducted at a higher rate before taxation, further reducing the tax base. Additional VAT Deduction: Eligible high-tech enterprises in advanced manufacturing may enjoy a 5% additional deduction on input VAT. 🏆 Enhancing Corporate Brand and Market Value The certification itself serves as a “stamp of approval” with multiple commercial benefits: National-Level Accreditation and Prestige: This is currently one of the most prestigious national-level accreditations available to many small and medium-sized enterprises (SMEs) and serves as authoritative proof of technological innovation capabilities. A “Stepping Stone” to the Market: When participating in bidding for major projects or applying for government science and technology programs, High-Tech Enterprise certification serves as a key advantage—and in some cases, a prerequisite for entry. A “Booster” for Capital Markets: It effectively enhances a company’s valuation and serves as a crucial metric for demonstrating corporate value and growth potential during financing, mergers and acquisitions, and initial public offerings (IPOs). 🏛️ Access to Local Support and Preferential Resources To foster the high-tech industry, local governments typically implement a series of concrete support policies: Direct Financial Incentives: Many...

Foreign Trade Operator Filing and Registration Form
🔑 Obtaining “Import and Export Operating Rights”: This is the key credential that grants a company the legal qualification to engage in the import and export of goods or technology, and it serves as the “entry requirement” for entering the foreign trade sector. 📋 A prerequisite for customs clearance: Without it, customs authorities will not process customs declaration and release procedures for a company’s imported or exported goods; it can be described as the “pass” for the entire foreign trade process. 🏛️ The foundation of government regulation: As a result of the transition from an approval system to a filing and registration system, it reflects a shift in the government’s regulatory approach—from strict pre-approval to gathering information and conducting in-process and post-event supervision through filing and registration.

AAA Credit Rating Certificate
The 3A rating is the highest credit rating assigned by rating agencies. It refers to bonds or companies that have received the highest credit rating from Standard & Poor’s or Moody’s, and is denoted by the rating symbol “AAA.” The 3A rating (also known as the AAA rating) is the highest credit rating assigned by rating agencies (such as Standard & Poor’s, Moody’s, China Chengxin International, and United Credit Rating) and applies to corporate entities or bonds. The long-term credit rating system used in China generally follows a three-tier, nine-grade structure, with AAA as the highest grade. An AAA rating indicates that a company has a high level of creditworthiness, low debt risk, sound operations, strong profitability, and promising prospects for growth. A corporate issuer with a long-term credit rating of AAA demonstrates an extremely strong ability to repay debt, is largely unaffected by adverse economic conditions, and has an extremely low risk of default; A long-term credit rating of AAA for a bond indicates that the bond is extremely safe and carries an extremely low risk of default. Obtaining an AAA issuer credit rating is an authoritative certification of a company’s comprehensive strength and reputation, helping to reduce financing costs and broaden financing channels. In the United States, only two companies—Johnson & Johnson and Microsoft—hold an AAA rating.

Compared with other traditional rotor profile designs, Jinjing rotor can save up to 15% energy.Our precision machined large-size roller bearings help to make our air end have a long service life. All these, together with our state-of-the-art internal manufacturing processes and strict manufacturing tolerances, provide excellent quality synonymous with the Jinjing name.Jinjing adopts an international advanced frequency conversion module, a special motor with speed up and down characteristics, and a set of PID parameters especially suitable for screw compressors. The control software has been tested by hundreds of thousands of compressors, with simple parameter settings and a friendly man-machine interface. The cooling of the frequency converter is specially designed. In order to support the user to set the best working pressure, the filtering area of the filter element of the oil-gas separator is increased.
