Frequently Asked Questions
Do imports of concrete mixers (HTS 847431) require any special certifications or import licenses for US entry?
Yes, concrete mixers must comply with US Environmental Protection Agency (EPA) emissions standards for non-road engines under 40 CFR Part 1039. Importers must file an EPA Declaration Form (3520-21) with Customs and Border Protection (CBP) and may need to provide a certificate of conformity from the engine manufacturer demonstrating compliance.
What are the specific packaging and crating requirements for shipping concrete mixers (HTS 847431) by ocean freight to ensure they are not damaged and clear customs smoothly?
Concrete mixers require robust, waterproof crating that fully protects the drum, engine, and hydraulic components from salt spray and impacts. The skid or crate must allow for safe lifting by container top-handlers, and all fluids must be drained with a declaration attached. Proper packaging with clear, durable markings of the gross weight and center of gravity is essential to avoid delays from customs or carrier rejection due to unsafe stowage.
Common Classification Mistakes for Concrete Mixers (8474.31)
A frequent error is classifying mobile truck-mounted concrete mixers under 8705.40 (special purpose motor vehicles) instead of 8474.31. The legal notes for Chapter 84 generally take precedence, making 8474.31 correct for the mixing function. Another mistake involves separately classifying the mixing drum or blades; these are considered parts of the mixer and should be classified under 8474.90 (parts). Ensure the machinery is not a simple mixing tub, which would fall under heading 7324 or 6810, but is a powered machine designed for mixing concrete.
