Date of issuance of ruling:

This is in response to your request for an advance ruling on the tariff classification of Dekol SN NEW. This product is manufactured by BASF SE (Germany).

TRS Number: 271240
Classification Number: 3906.90.00.90
Effective Date:

Product Description

According to the information received, this product is an acrylic copolymer salt in water that is described as a clear, yellowish, viscous liquid. The information received indicates that this product is used as a sequestering or chelating agent designed to scavenge calcium and magnesium ions in textile processes.

Analysis and Justification

Legal Note 4 to Chapter 39 states, in part, that the expression "Copolymers" covers all polymers in which no single monomer unit contributes 95 % or more by weight to the total polymer content.

The above Note further states that, for the purposes of Chapter 39, copolymers and polymer blends are to be classified in the heading covering polymers of that comonomer unit which predominates by weight over every other single comonomer unit.

Legal Note 6 to Chapter 39 states, in part: "In headings 39.01 to 39.14, the expression "primary forms" applies only to the following forms:

Heading 39.06 provides for "acrylic polymers in primary forms". The first paragraph of the Explanatory Notes to 39.06 reads:

The expression "acrylic polymers" covers polymers of acrylic or methacrylic acid, of their salts or esters, or of the corresponding aldehydes, amides or nitriles.

Based on the information provided, and given that the acrylic comonomer unit predominates by weight, the product meets the terms of heading 39.06 being a copolymer in primary form.

Given that the acrylic comonomer unit predominates by weight, and that the product is not a polymer of acrylamide, it meets the requirements of being an acrylic polymer in primary form, and as such, it is classified in heading 39.06.


Section 10 of the Customs Tariff directs that classification of imported goods shall be determined in accordance with the General Rules for the Interpretation of the Harmonized System. Section 11 of the Customs Tariff states that in interpreting the headings and subheadings, regard shall be had to the World Customs Organization's (WCO) Explanatory Notes to the Harmonized Commodity Description and Coding System.

General Interpretative Rule 1 (GIR 1) directs that titles of Sections, Chapters and sub- Chapters are provided for ease of reference only. For legal purposes, classification shall be determined according to the terms of the heading and any relative Section and Chapter Notes. Similarly, General Interpretative Rule 6 (GIR 6) directs that classification shall be determined according to the terms of those subheadings and any related Subheading Notes.

The Dekol SN NEW is classified under 3906.90.00.90 as other acrylic polymers in primary forms by GIR 1 and 6.
