Make 0/1 columns cod_flag (from cod) and returned_flag (from returned), 1 meaning Yes. The inputs X are category, order_value, discount_pct, delivery_days, customer_orders and cod_flag, with category one-hot encoded by pd.get_dummies(..., columns=["category"], dtype=int). The answer y is returned_flag. Split with train_test_split (test_size=0.25, random_state=42, stratify=y).
Built-in importance can favour columns with many values. Permutation importance shuffles one column at a time on the test part and measures how much the score drops. Train RandomForestClassifier(n_estimators=100, random_state=0), run permutation_importance on the test part (n_repeats=5, random_state=0), and store the column with the biggest mean drop in result.
