Import Tips

• Provide end-user statement or contract proving use in cellulosic pulp/paper machines to qualify for this specific provision

• Include technical specs showing fixed ratio design and compatibility with pulp refiners; misclassification to general gearboxes common

• Ensure customs declaration specifies 'for pulp/paper machines' to avoid default to higher-duty 8483.40 categories
