Import Tips

• Include ethoxylation degree (e.g

• 2-3 moles) in technical specs to confirm as surface-active agent

• Avoid packaging confusion with finished shampoos, which go to 3405; bulk shipments require bulk certs

• Test for insolubles per Chapter note to prevent reclassification as non-qualifying preparation
