In foreign trade transactions, product quality is the core cornerstone of cooperation, different stages of inspection services can accurately control the whole process of production, to help foreign trade enterprises to avoid risk, to protect the quality of delivery. As a professionalthird party inspectionAgencies.Inspector OnlineAfter years of deep plowing in the industry, we will sort out the pre-shipment inspection for you (PSI), in-production inspection (DPI), prenatal testing (IPI) Three types of core inspection of the applicable scenarios, to help enterprises according to the actual needs of the precise choice, so that quality control is more efficient, more in line with the scene.

I. Prenatal Inspection (IPI): Control at the Source, Avoiding Initial Risks

In-Process Inspection (IPI for short), is the core inspection before the official mass production of products, focusing on the “pre-production” and “initial trial production” two core scenarios, is the “first barrier” for quality control. It is the "first gate" for quality control.

Its core application scenarios mainly include three categories: First, the first cooperation on new products, enterprises are not familiar with the supplier's production process, product materials, through IPI to verify the quality of raw materials, production equipment debugging, process feasibility, to avoid fundamental quality problems after mass production; Second, the production of customized products, non-standard sizes, special processes, customized packaging products, IPI can be confirmed in advance mold accuracy, raw material ratios to meet customer requirements. Second, customized product production, involving non-standard size, special process, customized packaging products, IPI can confirm in advance whether the precision of molds, raw material ratio meets the customer's requirements, locking the accuracy of customized details from the source; Third, supplier replacement or production line adjustment, after changing the cooperative supplier, through IPI inspection of the trial production samples, to verify that the production capacity of the new supplier, the quality of the standard to match the needs of the enterprise, to reduce the quality of the change of supplier fluctuations brought about by the risk.

In the IPI test, theinspection of goodsThe online professional team will focus on verifying whether the raw material specifications are in line with the contractual agreement, whether the production process parameters are up to standard, whether the appearance, size and performance of the trial production samples are in line with the customer's standards, and at the same time, record any problems that may exist in the initial production, and give targeted optimization suggestions to eliminate the loss of “batch reworking” from the source.

Second, in-production inspection (DPI): process control, intercepting the interim hidden danger

During-Production Inspection (DPI for short), is in the product mass production process (usually completed 30%-50% output) to carry out the inspection, focusing on the “mass production stage”, is the timely detection and correction of process problems of the It is a “critical line of defense” for timely detection and correction of process problems.

The core application of this type of inspection scenarios are focused on: the mass production of products with a long production cycle, such as large furniture, batch clothing, electronic product assembly, etc., the production cycle of such products is long, if the initial no problem but the middle of the process deviation, can be intercepted in time through the DPI, to avoid the subsequent batch of unqualified; the second is the production of products with high requirements for production stability, such as children's products, medical equipment parts, automotive parts, etc., which are demanding quality details. Secondly, for products requiring high production stability, such as children's products, medical equipment parts, auto parts, etc., which have strict requirements on quality details, DPI can monitor the process stability in real time during the production process, so as to avoid batch quality problems due to workers' operation errors and equipment failures; thirdly, for orders that customers require stage-by-stage follow up, and some overseas customers pay attention to the progress and quality of the production, DPI can provide stage-by-stage inspection reports, so as to enable customers to grasp the real-time situation of the products' production, and to enhance the degree of trust in the cooperation.

When DPI is performed online, random samples of products in mass production are inspected, focusing on whether the production process continues to comply with standards, whether product consistency is up to standard, and whether there is any material loss or dimensional deviation during the production process. At the same time, production quantities and schedules are verified to ensure that the products can be delivered on time, and to avoid delays in production due to mid-term quality issues.

Pre-Shipment Inspection (PSI): the final gatekeeper, to ensure the quality of delivery

Pre-Shipment Inspection (Pre-Shipment Inspection, referred to as PSI), is the final inspection carried out before the product is fully produced, packaged and ready to ship, focusing on the “final confirmation before shipment”, is to protect the quality of delivery of the “l(fā)ast barrier ”, is also the most commonly used inspection services in foreign trade transactions.

The applicable scenarios cover most of the foreign trade orders, in particular: regular bulk product shipments, such as daily necessities, household appliances, hardware accessories, etc., through PSI to confirm the quality of the final product, the number of packages in line with the contract requirements; secondly, the customer explicitly requires pre-shipment inspection of the order, the overseas buyers usually designate the third-party inspection organization to carry out PSI, as the core basis for payment, release of goods; thirdly, the whole container of large-volume orders. The third is the whole container shipment of high-volume orders, such orders, once quality problems, rework, return and replacement costs are extremely high, PSI can be completed before shipment of a comprehensive check to avoid the whole container of goods in the bulk unqualified; Fourth, the product involves multiple rework or production adjustment of the order, after the pre-adjustment or rework of the product, the shipment of the product, through the PSI before the final confirmation is required, to ensure that all the problems have been rectified in place.

as a professioninspection companyThe PSI service of Goods Inspection Online covers all dimensions of verification: whether the appearance, size, function and performance of the product are in full compliance with the customer and contractual standards; whether the packaging is solid, clearly marked and adapted to the needs of long-distance transportation; whether the number of units shipped is in line with the order, and whether it is recommended to be matched with a product that meets the customer's specifications.Container Supervision ServiceIn order to ensure that the loading process is standardized, no damage to the goods, and ultimately issued a detailed inspection report for the delivery of foreign trade enterprises.

IV. Core differences between the three types of tests and the logic of choice

The three types of inspections cover the whole process of product production, and the core difference lies in the “intervention stage” and “core objective”: IPI focuses on the “source”, with the goal of avoiding the initial production risk and guaranteeing the IPI focuses on the “source”, the goal is to avoid initial production risks and guarantee production feasibility; DPI focuses on the “process”, the goal is to control the quality of mass production, and timely interception of medium-term risks; PSI focuses on the "end game", the goal is to confirm the quality of the final delivery and guarantee the transaction landing.

Enterprises in the choice, can follow the “on-demand combination, accurate adaptation” logic: the first cooperation of customized products, you can choose the “IPI + PSI” combination, from the source control to the final delivery of the whole chain of protection; regular batch products and short production cycle, the priority to choose PSI; long production cycle of complex products, you can choose “DPI + PSI” combination, real-time control of process quality to avoid large-scale problems in the final inspection. For regular batch products with a short production cycle, PSI is preferred, taking into account both efficiency and quality; for products with a long production cycle and complex processes, the "DPI+PSI" combination can be chosen to control the process quality in real time and avoid large-scale problems in the final inspection.
