Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as other methadone (INN) intermediates not specifically named
Unnamed methadone intermediates fall under the residual methadone subheading 2926.90.4300.
If for the corresponding non-nitrile alcohol precursor
Precursor alcohols without nitrile function classify under heading 2903 for halogenated/sulfonated/nitrated alcohols.
If pre-mixed with immunological products for hormone synthesis
Chapter Note 2(e) excludes immunological products to Chapter 30, but pure intermediates remain in Chapter 29.

Import Tips & Compliance
• Use UN-approved packaging for powders to prevent dusting; include MSDS with emetic identifiers if required for safety
• Verify batch purity >98% with HPLC certificates to match tariff's chemically defined compound requirement
• Avoid bulk packaging over 25kg drums, as it may raise diversion concerns during CBP examination
