Frequently Asked Questions
Are there any specific import licensing or regulatory compliance requirements for importing NBR rubber under HTS 400259, such as from the U.S. International Trade Commission (USITC)?
Yes, imports of NBR rubber under HTS 400259 are subject to an active antidumping duty order from the USITC (Investigation No. 731-TA-1498). Importers must file form ENTRY/SUMMARY with U.S. Customs and Border Protection (CBP) and may be required to provide a certification from the foreign exporter to prove the product is not subject to the order, or pay cash deposits of estimated antidumping duties.
What are the critical packaging requirements for shipping bulk acrylonitrile-butadiene rubber (NBR) in primary forms to prevent contamination and damage?
NBR in primary forms (e.g., bales, crumbs, or pellets) must be packaged in strong, sealed polyethylene liners within weatherproof containers to prevent moisture absorption and oxidation, which degrade the rubber. For sea freight, using 20ft or 40ft dry containers with proper blocking and bracing is essential to prevent shifting and damage to the bales during transit.
Common Classification Mistakes for NBR/SBR Rubber
A frequent error is misclassifying NBR/SBR blends under heading 4002.99 for 'Other' synthetic rubber instead of the correct 4002.59. Subheading 4002.59 is specific for copolymers of acrylonitrile-butadiene (NBR) and styrene-butadiene (SBR). Another mistake involves classifying finished articles like simple seals or washers here; if they are 'machined' or ready for use, they typically belong in Chapter 40 heading 4016 or 4017. Also, ensure the material is not a latex (heading 4002.11/4002.19) or a mixture with natural rubber that would change the heading.
