2026 Plastic Import & Export Agency: Avoid Solid Waste Identification and Anti-Dumping Duties Pitfalls

2026 Plastic Import & Export: Don’t Let "Solid Waste Identification" and "Anti-Dumping" Ruin Your Orders

In 2026’s foreign trade environment,the import and export of plastic products are far more than simple "declaring customs and shipping goods".As a veteran who has been deeply involved in this industry for 20 years,I have seen too many enterprises whose goods were stuck in ports for months due to insufficient policy prediction,and even faced the painful situation of return or destruction.Especially with the tightening of global environmental regulations and the rise of trade protectionism in various countries,Solid Waste Identification and Anti-Dumping Duties have become two sharp swords hanging over all plastic traders.

Relying on Shanghai Port’s geographical advantage and combined with a global agency network,Zhongshitong has been helping various plastic enterprises sort out compliance paths.Today I will not talk empty words,but directly target the most tricky pain points in plastic import & export,and break down a set of operable logic.

Import Section: "Identity Crisis" of Pellets and Solid Waste Red Lines

For plastic imports,whether new materials or recycled materials,the biggest fear is that customs question the "attributes" of your goods.Under the 2026 regulatory environment,customs’ crackdown on "solid waste" remains at a high level.Once your goods are judged as foreign waste,it is not just a matter of tariffs,but also environmental violations,facing huge fines even criminal liability.

Many importers easily confuse the boundary between "recycled plastic pellets" and "solid waste".In fact,customs’ judgment standards are very strict,mainly based on the Specifications for Identifying Solid Waste in Imported Recycled Plastic Particles.

• Appearance Consistency: Whether the size and color of pellets are uniform,and whether there are obvious impurities.
• Source Clarity: Whether you can provide complete foreign procurement contracts,invoices,and ISO-standard test reports.
• Odor and Toxicity: Whether the goods have pungent odor,and whether heavy metal content exceeds the standard.

I once handled a case where Manager Cai imported a batch of recycled PE pellets from Southeast Asia.To save freight,the supplier mixed some marginal materials.As a result,the goods were placed under customs inspection at Shanghai Yangshan Port,and samples were taken for inspection.Because it failed to pass the solid waste attribute identification,the goods were detained for 45 days,and finally had to be returned to the country,causing heavy losses.

Therefore,before import declaration,you must require the supplier to provide test reports issued by qualified third-party institutions,and truthfully fill in key information such as "source","whether recycled",and "brand" in the declaration elements.Do not take chances and try to "rush through customs".Zhongshitong usually advises clients to send samples to the pre-classification institution at Shanghai Port for consultation before shipment,confirm the correct HS code before arranging shipment,which can avoid more than 90% of classification risks.

Export Section: Compliance Breakthrough Under EU and US Anti-Dumping Duties

"If import is about preventing "waste",then export is about preventing "tax".In 2026,anti-dumping investigations by the EU and the US on specific Chinese-made plastic products (such as PVC,PET,and certain rubber products) remain normalized.If your destination country is the EU or the US and the product is on the anti-dumping list,high tax rates will directly eat up all your profits."

Many clients ask me how to avoid it?There is no shortcut,only a compliant path:

• Flexible Application of Certificate of Origin (Form A/RCEP): If it involves RCEP member countries,be sure to apply for RCEP Certificate of Origin to take advantage of tariff concession rules.If it goes to ASEAN countries,Form E is necessary.But note that destination country customs strictly verify the origin standards,and you must ensure that your "Chinese origin" composition meets the standards or meets the value-added criteria.
• Compliant Operation of Transshipment Trade: For products with extremely high anti-dumping tax rates,some enterprises will choose third-country transshipment.But in 2026,this requires extremely high risk control capabilities,which must be substantial processing in the third country,and obtain the third country’s certificate of origin,not just "changing containers".Zhongshitong’s global network can provide compliant transshipment logistics support in Malaysia,Thailand and other places,ensuring complete document chain.

In addition,export tax rebates are the lifeline for exporters.The HS codes for plastic products are very complex: for the same material,the tax rebate rate may be different when made into pellets and finished products.When declaring,"declaration elements" must be completely consistent with the actual goods,including "component content","monomer unit","purpose",etc.Once customs find that the declaration elements are inconsistent with the actual goods,not only will you not get the tax rebate,but you may also be identified as tax fraud,which is a dead spot for foreign trade enterprises.

Core Risk Control: HS Code Classification and Valuation Logic

Whether import or export,HS Code is the core of the core.Plastic products are distributed in Chapter 39 (Plastics and Articles Thereof) and Chapter 40 (Rubber) in the Tariff Schedule.Incorrect classification directly leads to incorrect tax rates and missing regulatory documents.

For example,ethylene polymers (PE) and propylene polymers (PP) differ by only one character,but their regulatory conditions are completely different.Another example is that some engineering plastics may be classified as "primary shapes" or "finished products".This directly affects whether an "Import License for Dual-Use Items and Technologies" is required for import.

In addition to classification,Customs Valuation is also a high-risk area in 2026.Plastic raw material prices are greatly affected by crude oil price fluctuations.If your import unit price is lower than the international market price in the same period,or the export price is significantly higher than the domestic average level,the system will automatically trigger the valuation risk control.

To deal with valuation,Zhongshitong advises enterprises to prepare sufficient price supporting documents: payment vouchers,insurance policies,freight notes,and even official quotation lists from manufacturers.For long-term cooperative old clients,we will even help establish a "advance price ruling" mechanism,locking the price interval recognized by customs in advance,avoiding valuation questions every time you clear customs,thus shortening the clearance time.

Practical Case: Inspection Lesson Caused by Inconsistent Declaration Elements

Let me share a real case from the end of 2025,which is highly referential for 2026 operations.Manager Mo is an enterprise specializing in exporting plastic seals,with products mainly sold to Germany.All along,they have declared HS codes as "vulcanized rubber (excluding hard rubber)",with a good tax rebate rate.

However,in one export,the customs system randomly placed the goods under inspection.The customs inspector found that although the material of the goods was rubber,they were "vulcanized" and had "metal reinforcing ribs".According to the Import and Export Tariff Schedule and Classification General Rules,rubber products with metal reinforcing ribs should be classified into another specific HS code,and the regulatory conditions involve "Exit Cargo Clearance Certificate".

Since the element of "reinforcing material" was not declared during the declaration,leading to HS code classification deviation.Although it was ultimately not identified as smuggling,the goods were detained for rectification,and the tax rebate process was suspended,resulting in Manager Mo’s capital chain being tight for a whole month.Afterwards,Zhongshitong helped Manager Mo sort out the declaration elements of all products,standardizing fields such as "brand,model,material,composition,purpose,whether reinforced",and established an internal declaration database.Since then,their clearance efficiency has increased by more than 40%.

This case tells us that Details Determine Success or Failure.In 2026,customs’ "document review" has been upgraded to "data profiling".Any tiny deviation in declaration elements may trigger the system’s risk control model.
