BTI (Binding Tariff Information) is an official EU customs decision confirming the classification of goods. Valid for 3 years, binding across all EU member states.

Product characteristics and tariff classification

CN code 390710 covers polyacetals (POM, polyoxymethylene) in primary forms. POM is a crystalline engineering polymer with excellent dimensional stability, low coefficient of friction, high fatigue resistance and good elastic properties. Two types are distinguished: POM-H (formaldehyde homopolymer) and POM-C (copolymer of formaldehyde with trioxane and dioxolanes). POM-C has better thermal stability while POM-H has higher stiffness. Products classified under this code come as granules or powder. POM is used in manufacturing precision mechanical parts, gears, bearings, zip fastener elements, fittings and automotive fuel system components. For customs classification, POM should be distinguished from other polyether polymers.

Regulatory requirements for import

Importing POM into the EU is subject to REACH. Formaldehyde monomer is carcinogenic Category 1B with CLP classification, imposing strict requirements on controlling residual formaldehyde content in the polymer. POM releases formaldehyde during thermal processing, requiring adequate ventilation in processing facilities. Food-contact POM must comply with Regulation (EU) No 10/2011, including a specific migration limit for formaldehyde of 15 mg/kg. POM in electrical equipment is subject to the RoHS Directive. POM for drinking water contact is subject to national regulations on water contact materials. The importer should have a certificate of analysis with residual formaldehyde content.

Trade and customs procedures

When importing POM under CN code 390710, customs documentation should include a technical specification covering POM type (homopolymer or copolymer), MFI, residual formaldehyde content and commercial form. Duty rates should be verified in the TARIC system. Major POM producers include Celanese (Celcon, Hostaform), BASF (Ultraform), DuPont (Delrin), Polyplastics and Korea Engineering Plastics. POM is one of the most important engineering polymers with annual production exceeding 1.5 million tonnes. POM granules are transported as non-hazardous goods. Preferential duty rates may be available under FTA agreements.

Frequently asked questions

What is the difference between POM-H and POM-C?

POM-H (homopolymer, e.g. Delrin) is a formaldehyde polymer with higher stiffness and mechanical strength. POM-C (copolymer, e.g. Hostaform, Celcon) contains comonomers improving thermal stability and hydrolysis resistance. Both types are classified under code 390710 as polyacetals in primary forms.

What formaldehyde limits apply to food-contact POM?

Food-contact POM must meet a specific migration limit for formaldehyde of 15 mg/kg food under Regulation (EU) No 10/2011. Additionally, the global migration limit is 10 mg/dm2. The manufacturer is required to issue a declaration of compliance confirming these limits are met.

Is POM subject to the CBAM mechanism?

No. Polyacetal POM and other plastics from Chapter 39 are not covered by the CBAM mechanism. This mechanism applies only to products from high CO2-intensity sectors such as steel, aluminium, cement, fertilisers, hydrogen and electricity.
