1. What is the main purpose of a trial order?
A: A trial order is a necessary step before establishing a stable supply relationship. Its core purpose is to verify the supplier's overall capabilities, focusing primarily on the following four aspects:
Product Quality: Assessing whether the surface, dimensions, and mechanical properties of the cold-rolled coils meet requirements.
Delivery Timeliness: Verifying the supplier's ability to fulfill commitments, including production cycle and logistics efficiency.
Service Level: Examining their performance in communication, contract execution, and problem response.
Price Competitiveness: Understanding the supplier's pricing strategy and negotiation space through small-batch transactions.
2. What is the most appropriate trial order quantity?
A: There is no absolute standard for the trial order quantity, but the core principle is "sufficient for assessment, but not enough to cause significant loss." A recommended starting point is 20-50 tons, which is usually the size of a minimum shipment unit. If the quantity is too small, such as a few tons, the supplier may lack the incentive to produce or schedule production, and it is also impossible to effectively test their capacity for bulk supply; if the quantity is too large, it defeats the purpose of the trial order in controlling risk.
3. How to ensure a smooth trial order process?
A: A rigorous trial order process typically includes the following steps, forming a closed-loop management system:
**Clarify Requirements and Define Specifications:** First, you need to be very clear about your needs. This includes the steel type (e.g., SPCC, DC01), grade, specifications (thickness, width), surface treatment (e.g., bright, roughened), mechanical property requirements (yield strength, tensile strength, etc.), and order weight.
**Select Suppliers and Request Samples:** Screen 2-3 potential suppliers in the market and obtain their samples or material reports as a basis for initial screening. Request samples from suppliers for testing; samples are the first quality check before the transaction.
**Communicate Details and Sign a Contract:** After selecting a supplier, clarify all transaction details in writing (e.g., a purchase order or simplified contract). This is a crucial step to avoid later disputes.
**Track Production and Confirm Logistics:** After signing the contract, regularly communicate with the supplier about the production progress and confirm logistics information and transportation status before shipment.
4. What are the main aspects to check during the acceptance process of a trial order?
A: Acceptance is the most crucial step in the trial order process and must adhere to the technical standards stipulated in the contract. The main acceptance items include:
Appearance Quality: Inspect the surface for defects such as scratches, dents, rust, and oil stains. Standards will be more stringent for applications requiring high surface quality (e.g., those used in appliance panels).
Dimensional Accuracy: Measure the thickness and width of the steel coil using professional measuring tools to confirm that they are within the allowable tolerances stipulated in the contract.
Mechanical Properties: Verify that the mechanical properties meet the standards. This mainly includes yield strength, tensile strength, and elongation. These data typically need to be tested by a qualified third-party laboratory.
Chemical Composition: Confirm, through methods such as spectral analysis, whether the content of major elements such as carbon, silicon, manganese, phosphorus, and sulfur meets the requirements of the standard grade.
5: If quality issues are discovered after a trial order, how does the contract protect me?
A: The contract is your core protection tool. When signing a trial order contract (or formal order), the following key clauses must be included to mitigate risks:
**Clear Quality Standards and Acceptance Methods:** The contract should clearly cite national standards (such as GB/T), industry standards, or mutually agreed-upon enterprise standards as the basis for acceptance, and specify the detailed inspection methods and sampling rules.
**Set a Quality Objection Period:** Clearly stipulate that you have the right to raise written objections to the quality within a specific number of days after delivery (e.g., 15 or 30 days). Exceeding this period may be considered acceptance of the goods as is.
**Define Clear Liability for Breach of Contract:** Specify in detail the handling methods for products that are not up to standard, such as returns, exchanges, price reductions, and compensation for losses such as lost wages.
**Preserve Evidence:** All communications with the supplier (emails, chat logs), samples, contracts, payment vouchers, inspection reports, etc., should be properly preserved. In case of a dispute, these will be the most compelling legal evidence.
