HS Code 4010.35 – Rubber; vulcanised, endless synchronous belts, of an outside circumference exceeding 60 cm but not exceeding 150 cm
HS code 4010.35 is the 6-digit subheading for rubber, vulcanised, endless synchronous belts, of an outside circumference exceeding 60 cm but not exceeding 150 cm. It is used for automotive timing belts, industrial synchronous belts, robotics drive belts, CNC machine belts and printer timing belts.
What HS 4010.35 covers
Synchronous belts, often called timing belts, are essential for applications requiring precise timing and power transmission without slippage, such as in automotive engines, industrial automation, and robotics. This specific size range (60-150 cm) covers a vast array of medium-sized machinery and equipment. International trade in these belts is driven by the global manufacturing sector's need for precision components. Countries with significant automotive industries (e.g., Germany, Japan, USA, South Korea) and advanced manufacturing (e.g., China, EU nations) are major importers, requiring these belts for both OEM and aftermarket replacement. Exporters are typically nations with strong rubber and precision engineering industries. Key considerations for trade include tooth profile accuracy, material composition (e.g., neoprene, polyurethane with fiberglass cords), and resistance to wear and temperature fluctuations, which are crucial for maintaining machinery performance and longevity.

Codes often confused with 4010.35
Common mistake. This code might be confused with 401036 (synchronous belts > 150cm to 198cm) or 401039 (other transmission belts), as the key differentiator is the precise circumference range.
Top exporters and importers of HS code 401035, 2025
In 2025, the largest exporter of HS code 401035 in UN Comtrade data was Italy, with 22% of world exports; the largest importer in UN Comtrade data was Germany, with 13% of world imports. The United Kingdom reports $218M of its chapter 40 exports without product detail (confidential), so it may also belong among the top exporters.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

What are common misclassifications for HS code 401035?
This code might be confused with 401036 (synchronous belts > 150cm to 198cm) or 401039 (other transmission belts), as the key differentiator is the precise circumference range.
Which countries are the top exporters of goods under HS code 401035?
In 2025, the top exporters of HS code 401035 in UN Comtrade data were Italy ($150M, 22% of world exports), Germany ($133M) and China ($67M). World exports came to about $668M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). The United Kingdom reports $218M of its chapter 40 exports without product detail (confidential), so it may also belong among the top exporters.
Which countries are the top importers of goods under HS code 401035?
In 2025, the top importers of HS code 401035 in UN Comtrade data were Germany ($84M, 13% of world imports), Poland ($67M) and France ($49M). World imports came to about $631M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
How is HS code 401035 structured?
HS code 401035 is a 6-digit subheading under the Harmonized System. The first 2 digits (40) identify the chapter, digits 3-4 (10) identify the heading, and digits 5-6 (35) specify the subheading. This code is standardized globally by the World Customs Organization.
What is the Brazil NCM code for HS code 401035?
In Brazil, HS code 401035 is NCM 4010.35.00. The last two digits are 00 because Brazil does not split this HS code further.
