5.4.3 If the buyer has other special requirements, they shall be determined through negotiation between the supplier and the buyer and shall be noted in the purchase order.

6.1 Chemical composition

6.1.1 The chemical composition analysis of recycled nickel battery raw materials shall be carried out in accordance with the provisions of YS/T 1342.1.

6.1.2 The analytical method for determining the actual nickel alloy content of recycled nickel alloy raw materials is as follows:

a) Extract a sample from the raw material, weigh and record the sample mass m;

b) When the sample contains non-nickel metals and inclusions, it should be crushed and sorted; if it cannot be separated, it should be treated as non-nickel metals.

c) Weigh and record the mass m1 of the separated nickel alloy.

6.1.3 The chemical composition analysis methods for other raw materials shall be carried out in accordance with the provisions of GB/T 15923, YS/T 341.1, YS/T 707, etc., or as specified by the supplier. It needs to be determined through negotiation between both parties and noted in the order form.

6.2 Appearance Quality The appearance quality of the raw materials is inspected visually.

6.3 Hazardous substances Hazardous substances in raw materials are inspected visually.

6.4 Other requirements Other requirements for raw materials shall be determined by sensory inspection or by negotiation between the supplier and the buyer.

7.1 Inspection and Acceptance

7.1.1 The raw materials shall be inspected by the supplier or a third party, and the quality of the raw materials shall comply with the provisions of this document and the purchase order.

7.1.2 The buyer may inspect the received raw materials in accordance with the provisions of this document or the purchase order. If the inspection results are inconsistent with those of this document or the purchase order...

The matter should be resolved through negotiation between the supplier and the buyer. If arbitration is required, it should be conducted by [the relevant authority/organization]. Both the supplier and the buyer will jointly take samples and process them at the buyer's location.

7.2 Batching Raw materials should be submitted for inspection in batches. Each batch should consist of raw materials of the same category, group (if any), and grade, with no limit on batch weight.

7.3 Test Items and Sampling

7.3.1 The inspection items for raw materials shall comply with the provisions of Table 2.

7.3.2 Raw material sampling shall be conducted randomly and in accordance with the provisions of Table 2.

7.4 Judgment of Test Results

7.4.1 The numerical rounding of the test results shall be performed in accordance with the provisions of GB/T 8170, and the rounding value comparison method shall be used for determination.

7.4.2 If any of the test results for the chemical composition, appearance quality, hazardous substances, or other requirements of the raw materials fails to meet the requirements, the entire batch of raw materials shall be deemed unfit. The material is substandard.

8.2 Packaging

8.2.1 Raw materials of different categories, groups (if any) and grades should not be mixed.

8.2.2 Raw materials should preferably be supplied in packaged or compressed form. Powdered and loose metals should be delivered in ton bags, or as agreed upon by both the supplier and the buyer. Determine the packaging method and specify it in the order form.

8.3 Transportation and storage

8.3.1 Raw materials should be properly protected during transportation to prevent packaging breakage, leakage, spillage, rainwater soaking, and exposure to direct sunlight, and should be kept separate from other items. Store and transport separately.

8.3.2 Raw materials should be stored in a dry, well-ventilated warehouse free of corrosive substances. They should not be stored together with chemicals such as acids, alkalis, and oils, and should be protected from rain. Damage, corrosion, moisture, etc.

8.3.3 To make full use of cargo space, when different categories and groups of raw materials are individually packaged, each truck, ship, or container may carry two or more types mixed together. Raw materials should be grouped, but should be placed in categories and clearly labeled.
