Importing Polypropylene from China: Tariffs, Applications, and Supplier Scam Prevention

After two decades sourcing plastics from China, I can tell you that polypropylene (PP) remains one of the most versatile and cost-effective materials—even with the 25% Section 301 tariff. US importers often overlook Chinese PP because of the duty, but smart buyers know that the right supplier can still deliver better margins than domestic alternatives. Here’s what you need to know to source PP from China profitably and avoid the common pitfalls.

What is made of polypropylene?

PP is used mostly in:

• packaging industry
• electrical and equipment manufacturing
• household appliances industry
• automotive industry
• construction materials.

There are many things on the market made of polypropylene:

• film for fresh food
• beach slippers, durable bags, luggage
• medical equipment
• furniture
• toys
• plastic bottles
• food containers and kitchen items
• car parts.

Who sources polypropylene from China?

The main destinations of polypropylene exports from China are Asian countries:

• Vietnam
• India
• Bangladesh
• Turkey
• Pakistan.

China is the 1st largest importer of polypropylene in the world. Why is that? China is the biggest manufacturer and needs materials to keep up with the demand.

Customs duty on PP

Importers must pay import tax, known as customs duty/tariff during customs clearance.

• TARIC is a database of trade measures in the European Union. The EU customs tariff on propylene (polypropylene, PP), HS code 3902 10 00 20, is 6.5%.
• HTS is a classification system used to determine customs duties to be paid on imports into the US and more. Polypropylene (HTSUS code 3902 10 00 00) imported to the US is subject to a general tariff of 6.5%. But in terms of importing PP from China, there is an additional tariff of 25%.

How to avoid China supplier scams

The key to profitable PP sourcing isn't just finding a low price—it's finding a reliable supplier who delivers consistent quality. Before placing any large order, always verify the factory with a third-party inspection and review their export history. At China-Check, we help US buyers vet suppliers, conduct on-site audits, and inspect shipments to ensure your polypropylene meets specifications. Don't let a cheap quote turn into an expensive mistake.

• always verify your potential partner – there are many unreliable suppliers!
• sign a commercial contract and make sure to include all provisions (Chinese and English versions)
• conduct inspections at various stages
• if you receive an email informing you that your supplier bank information has changed, reach out to them to verify it
• do not make any decisions in a hurry.
