I.Customer demand analysis 
1,Preliminary communication: Our professional sales team first conducts preliminary communication with the customer to understand the specific needs of the customer, including the application field of the required biological additives (such as which specific link in the petroleum industry), performance requirements, environmental protection standards and the expected results. 
2,Technical evaluation: According to the specific needs provided by the customer, our technical team will conduct a detailed technical evaluation to analyze whether the existing technology can meet the customer's needs, or whether further research and development of customized solutions are needed.

II.Scheme Design and Customization
1,Scheme design: Based on the technical evaluation results, our R & D team will design a preliminary product scheme, including the formula, production process and expected performance indicators of bio-additives, and prepare a detailed technical scheme report. , 2,Customer confirmation: submit the preliminary design scheme to the customer for in-depth discussion and modification to ensure that the scheme fully meets the actual needs and technical specifications of the customer. 
3,Customized development: After the customer confirms the scheme, we enter the customized development stage, including laboratory test, pilot test and amplification, until the samples that meet the requirements are produced.

III. Sample test and verification 
1,Internal testing: After the sample production is completed, we first carry out internal quality inspection and performance testing to ensure that the product meets the design standards and customer requirements. 
2,Customer validation: Samples are sent to customers for testing and validation in their actual production environment to confirm the suitability, stability and environmental performance of the product. 
3,Feedback and optimization: According to the customer's test feedback, we make the necessary adjustments and optimization to ensure that the final product can meet all customer expectations. 

IV. Mass production and delivery 
1,Preparation for mass production: After the sample is verified, we will make preparations for mass production, including production line adjustment, raw material procurement, production plan formulation, etc. 
2,Formal production: According to the production plan, large-scale mass production is carried out, and strict quality control is implemented to ensure that each batch of products meets the quality standards. 
3,Logistics and distribution: According to customer requirements, we arrange professional logistics and distribution services to ensure the safe and punctual delivery of products to the customer's designated location. 

V. After-sales service and technical support 
1,Instructions for use: We provide our customers with detailed product usage guidelines and operation training to ensure that our customers can use our biological additives correctly. 
2,Technical support: Set up a 24-hour customer service hotline and a technical support team to answer customers' questions at any time and provide remote or on-site technical support. 
3,Continuous tracking and improvement: pay regular visits to customers, collect feedback on product use, and constantly optimize products and services to ensure the stability and development of long-term cooperative relations.
