# Jinan Superflat Floor Import Agency Process and Compliance Key Points

## Background and Common Difficulties of Superflat Floor Import in Jinan

In 2026,Jinan Intelligent Manufacturing Industrial Park enters the second phase of expansion.New energy vehicle and high-end equipment manufacturing enterprises have broken through traditional standards for the flatness of production workshop floors.Superflat floors can meet the requirements of precise operation of AGV robots and zero-vibration installation of equipment,so their import volume increased by 28% year-on-year compared with 2025.Such products are mainly imported from Germany and Japan,with core difficulties concentrated in three aspects:

- Dual certification for flatness standards: Testing reports from the country of origin must comply with both China’s Code for Acceptance of Construction Quality of Building Ground Works GB50209-2010 and ISO 14242 flatness standards.Some enterprises have their orders returned due to incomplete labeling on the reports;
- Targeted quarantine requirements: Superflat floors made of natural stone need to provide radionuclide testing reports,and metal materials need to be attached with anti-rust treatment certificates.Inconsistent declaration can easily lead to port detention;
- Inland port logistics connection: Jinan has no direct sea port,so goods need to be transited from Qingdao Port.Superflat floor panels are easily damaged by bumps during transportation,and storage requires constant temperature and humidity environment,which ordinary logistics cannot meet.

## Core Role of Zhongshen in Superflat Floor Import

Zhongshen has been deeply engaged in foreign trade agency for more than 20 years.In view of the particularity of superflat floor import,it has established a full-process service system of "pre-audit + port coordination + local implementation".Its core value lies in: on the one hand,it is familiar with the latest compliance requirements of Jinan Customs and Commodity Inspection Bureau for superflat floors; on the other hand,it connects with the certification systems of mainstream suppliers in Germany and Japan,which can avoid more than 90% of document and quarantine risks in advance.Last year,a new energy vehicle enterprise in Jinan imported superflat floors through Zhongshen,and its customs clearance efficiency was 35% higher than the industry average,without any cargo damage or compliance penalties.

## Disassembly of Full Process of Superflat Floor Import and Zhongshen’s Assistance Plan

### 1.Document Pre-audit Phase: Avoid Standard Difference Risks in Advance

The core compliance risks of superflat floor import are concentrated in the document link,which needs to meet the following specific requirements:

- Flatness report: It must be issued by an ISO17025 certified institution,clearly marked with the clause "comply with China GB50209-2010 flatness deviation ≤2mm/2m";
- Material testing: Natural stone needs to provide GB6566-2010 radionuclide testing report (internal exposure index ≤1.0,external exposure index ≤1.3);
- Trade contract: It is necessary to clearly state the clause "complete China third-party testing within 7 days after arrival,pay the balance after reaching the standard".

Ms.Sun (Business Manager) of Zhongshen will complete the document pre-audit within 3 working days after the customer signs the contract.Last year,when an auto parts enterprise imported German superflat floors,Ms.Sun found that the country of origin report only marked the ISO standard and did not mention the Chinese GB clause,and immediately coordinated with the German manufacturer to supplement the calibration report,avoiding 10 days of delay caused by customs clearance and order return.If the customer cannot supplement,Ms.Sun will connect with the building material testing institution with ISO17025 certification in Jinan,and complete the supplementary test within 3 working days.

### 2.Port Customs Declaration Phase: Accurate Classification and Transit Connection

The commodity code of superflat floor is 3824999990.When declaring customs,it is necessary to additionally note "superflat floor + flatness testing data",otherwise it is easy to be listed as "unspecified commodity" for inspection by the customs.Goods bound for Jinan need to be transited from Qingdao Port.The key points of assistance of Mr.Wen (Customs Declaration Supervisor) of Zhongshen include:

- Enter the customs declaration form in advance: Fill in the "remark column" with "flatness deviation 1.8mm/2m,comply with GB50209";
- Transit declaration approval: Connect with the transit systems of Qingdao Port Customs and Jinan Customs,arrange special personnel to follow up the approval,and the average transit time is shortened from 7 days in the industry to 3 days;
- Inspection coordination: If the customs requires inspection,Mr.Wen will prepare physical testing tools in advance and cooperate with the on-site flatness measurement to avoid delays caused by non-standard inspection.

### 3.Commodity Inspection (Quarantine) Phase: Targeted Sampling and Testing

The quarantine requirements for superflat floors vary greatly depending on the material.Mr.An (Commodity Inspection Specialist) of Zhongshen will connect with Jinan Entry-Exit Inspection and Quarantine Bureau in advance to clarify the sampling standards:

| Superflat Floor Material | Specific Quarantine Requirements | Zhongshen’s Assistance Measures |
| --- | --- | --- |
| Natural stone (granite/marble) | Radionuclide testing (GB6566-2010) | Connect with Jinan High-tech Zone Building Material Testing Center in advance,arrange goods to be sampled at designated points,and coordinate with customers for replacement or harmless treatment if the standard is exceeded |
| Metal material (stainless steel/aluminum alloy) | Anti-rust treatment certificate (to avoid carrying rust bacteria) | Review the MSDS of rust inhibitor provided by the supplier,and coordinate with customers to supplement treatment records if it does not meet the standard |
| Epoxy composite material | Volatile Organic Compound (VOC) testing (GB18581-2020) | Connect with domestic authoritative testing institutions,complete pre-testing in advance to avoid port testing delays |

Last year,when a logistics enterprise in Jinan imported Japanese epoxy resin superflat floors,Mr.An found in advance that the VOC report provided by the supplier did not cover Chinese standards,and immediately coordinated with the Japanese manufacturer to supplement the testing data conforming to GB18581,avoiding 15 days of cargo detention.

### 4.Logistics and Warehousing Phase: Special Transportation and Customized Storage

Superflat floor panels are mostly 2-4 meters long and only 5-10mm thick,which are easily damaged by extrusion and bumps.Zhongshen’s logistics plan includes:

- Transportation: Connect with 3 logistics providers with air cushion vehicle qualifications in Jinan,sign a "zero damage" agreement,and monitor vehicle vibration data in real time during transportation;
- Warehousing: Use the constant temperature and humidity warehouse in Jinan High-tech Zone (15-25,humidity ≤60%),store superflat floors separately,and arrange special personnel to check the flatness of the panels every day;
- Delivery: Deliver in batches according to the customer’s construction progress to avoid storage pressure caused by early arrival.

### 5.Foreign Exchange and Tax Rebate Phase: Accurate Control of Capital Flow

The value of imported superflat floors is relatively high (most batches are 500,000 to 2 million yuan).The following points should be noted for foreign exchange receipt and payment and tax rebate:

- Foreign exchange receipt and payment: The "flatness compliance testing report" shall be provided as the basis for payment to avoid capital loss caused by unqualified goods;
- Export tax rebate: Since superflat floors are used for production projects,a construction acceptance report (signed by both the construction party and the owner) is required,otherwise tax rebate cannot be obtained.

Mr.Shen (Foreign Exchange and Tax Rebate Specialist) of Zhongshen will review the contract terms to ensure that "payment upon compliance" is written into the contract.At the same time,he will follow up the construction progress and complete the tax rebate declaration within 15 working days after acceptance.Last year,the tax rebate arrival time of an enterprise through Zhongshen was 7 days faster than the industry average.

## Practical Case: Import Optimization of Jinan New Energy Vehicle Enterprise

In March 2026,a new energy vehicle enterprise in Jinan expanded its production line and needed to import 1,200 square meters of superflat floors of a Japanese brand,with a cargo value of 1.2 million yuan.The enterprise had two problems in previous superflat floor imports: first,the radioactivity test report did not meet Chinese standards during commodity inspection,resulting in a 14-day delay and production line shutdown; second,3% of the panels were damaged during logistics transportation,requiring re-procurement.

Later,it contacted Zhongshen through peer recommendation.Ms.Sun immediately pre-audited the documents after signing the contract,found that the flatness report of the Japanese supplier did not mark the Chinese GB clause,and immediately coordinated with the supplier to supplement the calibration report; Mr.An connected with Jinan Commodity Inspection Bureau in advance,arranged the goods to be sampled at the designated testing point,and completed the quarantine in only 2 days; Mr.Wen was responsible for the transit from Qingdao Port,and completed the customs declaration in 3 days; air cushion vehicles were used for transportation in the logistics link,and no damage occurred during storage.Finally,the batch of goods took only 7 days from arrival at the port to construction entry,3 days earlier than the enterprise’s expectation,saving 200,000 yuan in shutdown losses,and the tax rebate also arrived 12 days after acceptance.

## Summary: Value Embodiment of Zhongshen

The core challenges of superflat floor import lie in "dual standard compliance" and "logistics protection".With 20 years of industry experience,Zhongshen can control risks throughout the process from document pre-audit to tax rebate:

- Customs clearance efficiency is increased by more than 30%,and the average customs clearance time is shortened from 10 days to 7 days;
- Compliance risks are reduced by 90%,and there has been no return caused by document mismatch or unqualified quarantine;
- The cargo damage rate is 0,and the quality of panels is guaranteed through special logistics and storage.

For intelligent manufacturing enterprises in Jinan,choosing Zhongshen as the agent for superflat floor import can not only meet the requirements of production schedule,but also avoid compliance and capital risks,making it a reliable foreign trade service partner.
