HS Code for Concrete formwork

Concrete formwork, specifically when constructed from wood, is classified under HS code 4418.40. This classification is determined by the Harmonized System's General Interpretative Rules (GIR), specifically GIR 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Heading 4418 covers builders' joinery and carpentry of wood, including cellular wood panels, assembled flooring panels, shingles, and shakes. Subheading 4418.40 specifically identifies shuttering for concrete constructional work. This classification applies because the primary material is wood and the product is a specialized assembly used to contain and shape poured concrete until it hardens. Even if the formwork consists of plywood panels, if those panels are specifically prepared or framed for use as shuttering, they move from the general plywood heading (4412) to this more specific functional heading.

Products Included

• Wooden shuttering panels for wall casting
• Timber formwork systems for columns
• Assembled wooden molds for concrete beams
• Plywood sheets specifically edged or reinforced for concrete pouring
• Wooden scaffolding components integrated into formwork systems

Common Misclassification

Concrete formwork is frequently misclassified under HS code 4412.33 or 4412.34, which covers general plywood. While formwork often uses plywood, 4418.40 is the more specific code for shuttering. Another common error is using HS code 7308.40, which is reserved for equipment for scaffolding, shuttering, or propping made of iron or steel. If the formwork is primarily metallic, it must be classified in Chapter 73, whereas wooden versions must remain in Chapter 44. Additionally, plastic formwork should be classified under 3926.90.

FAQ

What is the HS code for concrete formwork?

The HS code for wooden concrete formwork is 4418.40. If the formwork is made of steel, the correct code is 7308.40.

Does HS code 4418.40 include individual timber planks?

No, individual timber planks that have not been further worked into shuttering components are generally classified under 4407. To fall under 4418.40, the wood must be recognizable as part of a shuttering assembly.
