Each batch of products shall be accompanied by a quality certificate, and its content shall be implemented in accordance with the provisions of the marking.

6.2 The product is inspected by batch, taking one batch of ingredients as a batch; and the maximum batch quantity is 50t.

6.3 Sampling of solid or bulk products shall be carried out in accordance with the provisions of GB/T 6679. Sampling of liquid products shall be carried out in accordance with GB/T 6680.

6.4 Place the sampled product in a clean, dry container and mix quickly. Take 600 g of solid sample or 600 mL of liquid sample; divide them into two clean, dry containers, seal and label them, indicating the name of the manufacturer, product name, batch number or production date, sampling date, and sampler’s name. One bottle is used for product quality analysis, and the other bottle shall be kept for at least two months for re-inspection.

6.5 After multiple fractionation of the solid sample, take out about 100 g, quickly grind it until all of it passes through a 0.50 mm sieve (if the sample is wet, it can pass through a 1.00 mm sieve), mix well; and place it in a clean, dry container for determination.

6.6 After shaking the liquid sample for several times, quickly take out about 100 mL of it; and place it in a clean and dry container for determination.

8 Packaging, Transportation and Storage
