Direct identification vs substitution manufacturing
| Path | Enterprise example |
|---|---|
| 19 U.S.C. 1313(a) direct identification manufacturing | Imported input is actually used in the exported or destroyed manufactured article. |
| 19 U.S.C. 1313(b) substitution manufacturing | Imported duty-paid merchandise or merchandise classifiable under the same 8-digit HTS subheading is used in production, and qualifying articles are exported or destroyed. |
Manufacturing data needed
- Import entries and duty paid
- Input product master, HTS, quantity, value, and origin
- Bills of material and production orders
- Yield, scrap, relative value, or allocation support
- Inventory receipt and transfer records
- Export or destruction records for finished articles
- Applicable general manufacturing ruling acknowledgment or specific manufacturing drawback ruling approval structure
- Reviewer notes explaining provision selection and calculation
Why this is high value
Manufacturing drawback is often the best path for chemicals, pharmaceuticals, electronics, automotive parts, industrial equipment, and oil and gas supply chains. It is also evidence-heavy. A weak manufacturing record can turn an otherwise valuable claim into a CBP review problem.
