Classification of hair perm solution under HS 3305.20
HS code 3305.20 is the specific classification for preparations used for permanent waving or straightening of the hair. This code is part of Chapter 33, which deals with cosmetics and toilet preparations. The classification is determined by the chemical function of the product, which is designed to alter the structure of the hair fiber permanently or semi-permanently. Heading 3305 covers all hair preparations, and 3305.20 is the designated sub-heading for products that facilitate waving or straightening. This includes both the active waving lotions and the neutralizing or "fixing" solutions used in the process. These products often contain thioglycolates or other reducing agents that break the disulfide bonds in the hair. The classification is specific to the chemical action of the product rather than its physical form (liquid, cream, or gel). If a product is marketed and formulated to straighten or curl hair through chemical modification, it must be classified here. This distinguishes it from temporary styling products like gels or sprays which only provide a surface-level hold. Proper classification is vital for regulatory compliance, as these chemicals are often subject to specific safety standards.

Codes often confused with 3305.20
Common mistake. These solutions are often misclassified under 3305.90 (other hair preparations). While 3305.90 is a catch-all, 3305.20 is more specific for structural hair modifiers. They should also not be confused with 3824.99 (chemical products n.e.c.) because they are retail-ready cosmetic preparations.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
