What Data for This Category Looks Like
Data for due diligence in the plastics and rubber industry comes from customs import and export declaration forms, commodity spot trading platform quotes, industry association monthly reports, and public quality inspection reports from manufacturing enterprises. Update rhythms vary significantly: spot quotes update daily, industry reports are released monthly or quarterly, and customs declaration data lags by 1 to 2 months. Document structures include basic fields such as HS code, batch number, gross weight, net weight, product grade, and origin, plus quality inspection indicators including tensile strength, melt index, and density. Most field units are kilograms, tons, MPa, and g/10min.
What Constraints These Characteristics Impose on Workflow Orchestration
Differences in multi-source data formats require workflows to be configured with multiple parsing node types, to adapt to CSV-format transaction data, PDF-format quality inspection reports, and real-time web-based quotes. Data sources with different update rhythms need to be bound to distinct scheduled trigger rules. This avoids frequently pulling static industry reports or delaying retrieval of real-time spot data. Inconsistent field units require additional unit conversion steps. Without these steps, LLMs cannot accurately recognize the meaning of cross-source indicators. Parsing long documents such as annual industry reports requires adjusting splitting parameters, to prevent key indicators from being truncated.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Documents such as plastics and rubber quality inspection reports and customs declaration forms have high content density. Long document parsing takes a long time, and 600 seconds covers most batch parsing scenarios |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Bulk uploaded industry annual reports and packaged files of multiple batches of declaration forms have large volumes. 2000 MB meets conventional bulk import requirements |
Segment Length | 800–1200 characters | Core plastics and rubber indicators such as melt index and tensile strength are mostly concentrated in single paragraphs. Excessively long segments interfere with key information extraction |
Knowledge Base Retrieval Count | Top 6 entries | Industry segmented data mostly consists of professional information for the same category. Too many retrievals introduce redundant content, while too few fail to cover all key indicators |
Similarity Threshold | 0.75–0.85 | Differentiate between different grades of plastics and rubber products in the same category. A threshold that is too low introduces irrelevant product data, while a threshold that is too high misses valid matching items |
API_REQUEST_TIMEOUT | 120 seconds | Workflows complete multi-source data pulling, parsing and integration. The timeout period must adapt to the total duration of multi-step execution |
The parameter values provided on this page are all conventional recommendations used as starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Mistakes
- Phenomenon: Calling the published workflow API returns a
408 Request Timeouterror. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and parsing time for plastics and rubber bulk declaration forms or long quality inspection reports exceeded the default timeout limit. - Phenomenon: Key indicator fields are missing or have incorrect units in the generated due diligence report. Cause: No unit conversion node was configured, and units of data from different sources (tons and kilograms, US dollars and RMB) were not unified, causing the LLM to fail to correctly recognize field meanings.
- Phenomenon: Content misalignment occurs after long text processing, and markers are not added as required. Cause: The
Segment Lengthparameter was not adjusted for the long text workflow, and segmentation logic does not match the content distribution rules of plastics and rubber industry documents.
How to Confirm Proper Configuration
- Upload a single plastics and rubber customs declaration form, check whether parsed text is split according to the
Segment Lengthparameter, with no excessive truncation or redundant segments. - Call the workflow test API, pass preset test parameters, and verify whether returned results correctly reference configured knowledge base content.
- Upload a packaged file with a volume close to
UPLOAD_FILE_MAX_SIZE, confirm that upload and parsing processes have no errors, and the file reading function works properly. - Simulate a bulk data processing scenario, check whether API requests complete responses within the duration set by the
API_REQUEST_TIMEOUTparameter.
