It is necessary for importers to establish effective quality control procedures to ensure the timely delivery of finished products that meet all relevant quality and safety standards. For brands or retailers, active quality control is essential to meet these challenges and optimize supply chain performance.

There are different types of toilets on the market. Common toilets on the market are generally divided into one-piece toilet assembly and two-piece toilet assembly. In recent years, some companies have chosen to develop smart toilets through continuous technical research, which have warm water washing, warm air drying, and seat Loop heating, sterilization and other intelligent and humanized functions.

HJ Service provides inspection services for toilets at every stage: from supplier investigation, audit to the quality control, and final delivery of toilets during the process.

HJ’s quality experts understand the customer’s requirements, ensure that on-site inspections are properly performed on-site, and finalize clear reports to explain and explain all details.

Throughout the quality control process, we will verify the appearance quality, specifications, functions, safety of your household appliances, and whether it meets the US, EU, and many other specific standards.

During the Pre-shipment inspection, the inspector should find various defects by inspecting the packaging, markings, labels, instruction manuals, accessories, barcodes, functions, and the appearance/appearance of the product. During the inspection of toilets, we found some common major and minor defects, including but not limited to broken, crack, deformed, glaze bubble, cover deviation, stains, scratches, missing accessories, sharp corners, incorrect barcodes, poor paint, and poor assembly, etc.

• Identify any issues in product size/specification to save cost and time.
• Reduce defects/flaws in the product and maintain a good brand image of the product.
• Save on possible rework and product recall costs.
• Confirm that the homeware/Kitchenware will not be damaged during packaging and loading.

We will identify and classify defects based on your Acceptance Quality Limits (AQL), verify the quality of mass production, perform product function and reliability tests on-site, and assess your compliance with product specifications and sizes.

Assess the quality of your product materials and workmanship, using a number of quality control checks and tests, including:

1. Barcode Scanning Test

Conduct a barcode scanning test to ensure the accuracy of product information and prevent errors in tracking and inventory management.

2. Instruction Manual Check

Verify that the instruction manual is clear and easy to understand, providing correct guidance for installation and usage to ensure that users can operate the product smoothly.

3. Accessories Check

Check for the completeness of all accessories to ensure they meet design specifications and avoid potential installation issues.

4. Assembly Check

Inspect the assembly of all toilet components to ensure they are securely fitted together, guaranteeing the structural safety and stability.

5. Water Leakage Check / Leak Tightness Check

Perform water leakage testing to ensure the toilet is watertight during normal use, preventing any water loss and potential damage.

6. Stability / Wobble Base Check

Evaluate the stability of the toilet after installation to ensure it does not wobble during use, providing comfort and safety for users.

7. Ball Emissions Testing

Test the flushing performance of the toilet to ensure effective waste removal and prevent clogging issues.

Place 100 polypropylene balls (each ball 19mm dia. 3g) in the toilet, starts flushing, test 3 times, The emission balls shall not less than 85pcs in 3 testing average.

8. Destructive Test for Seat Cover

Conduct a destructive strength test on the seat cover to ensure it does not easily break or fail upon repeated use.

9. Water Consumption Check

Measure the water usage during flushing to ensure compliance with international water conservation standards.

10. Splash Pollution Check

Test the design of the flushing action to ensure it does not cause excessive splash pollution during use.

11.Flushing tests

a.1 Sawdust test (or by ink):

20g of fine dry wooden sawdust. Moisten the complete inner surface of the WC pan below the flushing rim and above the surface of the water in the trap. Immediately afterwards, sprinkle that sawdust as completely and evenly as possible over the moistened surface. Flush the WC pan and measure any unwashed area. Repeat this procedure 5 times.

a.2 When tested in accordance with a.the arithmetic average of any unflushed area below the rim and above the surface of the water in the trap shall not be more than 50 cm2 after five flushing operations.

b. Flushing of toilet paper:

12 sheets of toilet paper: individuals sheets shall have a size of approximately 140 mm x 100 mm. Individually loosely crumple 12 sheets of toilet paper and drop them separately one after the other into the WC pan within a time of 14 s to 18 s. Operate the flushing mechanism within 2 s of the last sheet being dropped into the WC pan. Check for and remove any paper not flushed out of the bowl and the trap. Repeat this test 5 times.12 sheets of toilet paper shall be flushed out of the WC pan a minimum of 4 times out of five tests.

Performance and reliability are critical to ensure consumer satisfaction. especially Smart Toilets. However, some reliability tests cannot be performed at the inspection site. It requires a specific environment and test equipment to ensure compliance with applicable safety standards and regulatory requirements. AQI Service Inspectors can randomly take samples in production according to customer requirements and forward them to tested by an accredited laboratory.

12. Weight Check / Loading Test

Inspect the weight of the toilet and its load-bearing capacity to ensure safety during regular use.

13. Colour Comparison Check

Ensure that the color of the toilet matches the design specifications, maintaining consistency and avoiding appearance issues due to color variance.

14. Fatigue Test

Conduct durability testing under prolonged use to evaluate the toilet’s reliability under various usage conditions.

15. Product Size Measurement

Verify that the dimensions of the toilet conform to design specifications, facilitating installation and meeting the needs of domestic and international markets.

Summary

These quality control measures are essential for ensuring that toilets exported from China meet international standards. By implementing these checks diligently, we can reduce the risk of customer dissatisfaction and recalls, thereby maintaining the reputation of our products in the global market.
