Key Takeaways
- Capacity growth on India-China lanes makes it easier for Canadian importers to shift sourcing between the two, but CUSMA origin claims fall off and MFN duties apply.
- SIMA covers dozens of steel, chemical, and textile HS codes from both India and China; switching suppliers without checking subject-goods lists can trigger 50%+ anti-dumping margins.
- Every CAD filed through the CARM Client Portal requires an HS 6-digit classification, and similar-looking goods from India versus China often fall under different headings with different duty rates.
- If your supplier changes country of manufacture mid-contract, update your importer records and tell your broker before the first shipment clears—post-release corrections are painful under AMPS.
Sourcing shifts between India and China touch every CAD you file
Container capacity on the India-China trade has jumped in the past six months. Ningbo Ocean Shipping, X-Press Feeders, and a handful of regional carriers have added vessel slots and expanded port calls between Nhava Sheva, Shanghai, Ningbo, and the Pearl River Delta. That capacity growth makes it cheaper and faster for manufacturers in both countries to exchange components, and it makes it easier for Canadian importers to switch suppliers between the two markets when lead times tighten or prices move.
From a customs brokerage perspective, those sourcing shifts land on your desk as HS classification changes, origin-declaration updates, and SIMA compliance questions. A steel valve body machined in Pune falls under a different SIMA finding than the same part forged in Dongguan. A polyester-blend woven fabric from Gujarat may attract MFN duty of 18 percent, while a similar fabric from Zhejiang may be subject to anti-dumping margins on top of the base rate. The underlying commercial logic—lower FOB price, shorter lead time, better quality control—doesn't change the fact that every Commercial Accounting Declaration filed through the CARM Client Portal requires accurate country of origin, correct HS 6-digit classification, and a defensible customs value.
We've seen three recurring problems in the past quarter as clients move purchase orders between India and China, and all three create post-release headaches that are easier to prevent than fix.
CUSMA origin claims disappear when you leave North America
If your current supplier is in Mexico and you're claiming CUSMA preferential duty, switching to India or China means you lose that tariff preference. MFN rates apply, and depending on the HS heading, the difference can be eight to twenty percentage points. Textile and apparel imports (chapters 61, 62, 63) are the most common trap: CUSMA brings the rate close to zero, but MFN duty on woven garments from India sits at 18 percent, and China faces the same base rate plus potential SIMA measures on certain fibres.
The same principle applies to CETA origin if you're currently sourcing from the EU. Goods transshipped through India do not automatically qualify for CETA unless the EU supplier provides an EUR.1 certificate and the goods meet the direct-transport rule. A container that stops in Mumbai for consolidation and then moves to Montreal still qualifies if it stayed under customs seal, but if the goods were unpacked, relabeled, or mixed with non-EU cargo, the preference is lost.
Before you issue the first purchase order to the new supplier, confirm the landed-duty math. We run duty calculations for clients weekly, and the all-in cost difference between CUSMA-qualified and MFN can flip the commercial case. If you're importing 40-foot containers monthly, a ten-point duty swing is twenty to thirty thousand dollars per year.
SIMA subject goods multiply when you source from both countries
The Special Import Measures Act covers more than 150 product-country combinations as of 2024, and both India and China appear on dozens of those findings. Steel pipe and tube (HS 7306), rebar (HS 7214, 7308), photovoltaic modules (HS 8541), certain fasteners (HS 7318), and concrete reinforcing bar all carry anti-dumping or countervailing duties from one or both countries. The margins range from single digits to over 200 percent, and they apply on top of MFN customs duty and GST.
If your supplier changes from India to China—or the other direction—check the current SIMA measures list published by CBSA before the first shipment leaves the origin port. The fact that your existing Indian supplier's goods cleared without SIMA duty does not mean the new Chinese supplier's identical product will. Conversely, some findings cover India but not China, or apply to specific manufacturers rather than country-wide.
When CBSA identifies subject goods on a CAD, the system automatically calculates the SIMA amount and adds it to the RPP monthly statement (K84). There is no discretion and no grace period. If you didn't budget for the margin, your cash-flow forecast is wrong the day the container releases. The downstream fix—applying for a SIMA exclusion or proving the goods are out of scope—takes months and requires engineering data, production records, and sometimes lab testing. Build the SIMA check into your supplier-qualification process, not your post-release cleanup.
HS classification shifts with country of manufacture more often than you expect
Two goods that look identical may fall under different HS headings depending on material composition, manufacturing method, or intended use, and those differences often correlate with country of origin. Indian manufacturers may use a different alloy blend, polymer formulation, or textile weave than their Chinese counterparts, and those technical differences can push the product into a different HS 6-digit classification.
A steel flange forged in India might classify under HS 7307.91 as a malleable cast-iron fitting, while the same flange cast in China using a different carbon content falls under 7307.19 as a non-malleable fitting. The duty rate difference is two to three percentage points, but the real risk is AMPS penalties if CBSA audits your CAD filings and decides your classification was unreasonable. Under the Administrative Monetary Penalty System, a single misclassification that results in lower duty can trigger a CAD 1,500 to CAD 25,000 penalty depending on the duty shortfall and your compliance history.
If you're switching suppliers between India and China, treat it as a new product introduction. Get the technical spec sheet, the material declaration, and photos of the finished good. Run the HS classification before the first shipment, and if the new supplier's product differs in any material way, file the CAD under the correct heading from day one. Post-release corrections are possible under section 32.2 of the Customs Act within four years, but voluntary disclosure does not erase AMPS exposure if CBSA concludes you should have known better at the time of import.
Warehousing and release prior to payment under CARM
Most Canadian importers filing CADs today operate under release prior to payment, posting an RPP bond and settling duties monthly through the K84 statement. When you add a new origin country or increase volumes from an existing one, your monthly duty and GST liability can spike, and if it exceeds your bond coverage, CBSA will hold future shipments until you top up the security.
We typically recommend clients keep their RPP bond at 150 percent of average monthly exposure, but if you're running pilot orders from a new India or China supplier and the duty rate is materially higher than your current mix, recalculate the bond math before the container arrives. A 40-foot container of subject goods with a 60 percent all-in duty and SIMA margin can add CAD 40,000 to your monthly liability. If your bond sits at CAD 80,000 and you're already using CAD 50,000 for existing shipments, you're over the line.
Once the goods release, most of our clients cross-dock through FENGYE's Montreal location for deconsolidation and LTL distribution, or hold in the bonded zone if final customs compliance review is still open. If you're mixing India and China cargo in the same container, make sure the commercial invoice breaks out the two origins clearly. CBSA's risk-assessment algorithm flags mixed-origin consolidations more often than single-country loads, and an examination request adds two to four days to your release timeline.
What to do before your next PO to India or China
Confirm the HS classification, check the current SIMA measures list, calculate the all-in landed duty, and update your importer-of-record details in the CARM Client Portal if the supplier's country code changes. If you're moving volume between the two countries on a regular basis, treat each origin as a separate SKU for compliance purposes, even if the product description and your internal part number stay the same.
We file CADs for clients importing from both India and China daily, and the cleanest clearances come from importers who brief us on sourcing changes before the booking confirmation goes to the freight forwarder. If your container is already on the water and you're not sure whether SIMA applies or your bond is large enough, that's a problem we can still solve, but it's faster and cheaper to get it right on the front end.

Frequently Asked Questions
What is a CAD and when do I need to file one?
A Commercial Accounting Declaration (CAD) is the CARM-era customs declaration that replaced the old B3 form. You file a CAD for every commercial import into Canada, typically within five business days of release under the release prior to payment model. The CBSA CARM Client Portal handles the submission.
Does CUSMA (USMCA) cover goods manufactured in India or China?
No. CUSMA preferential duty rates apply only to goods originating in Canada, the United States, or Mexico under the rules of origin in Chapter 4 of the agreement. Imports from India or China pay MFN (most-favoured-nation) tariff rates unless covered by another FTA or GSP.
What is SIMA and how do I know if my HS code is subject?
The Special Import Measures Act (SIMA) imposes anti-dumping and countervailing duties on specific goods from specific countries. The Canada Border Services Agency maintains the current list of SIMA measures; as of 2024 there are over 150 active findings covering steel pipe, rebar, chemical products, and textiles from China, India, and other jurisdictions.
Can I claim CETA origin for goods transshipped through India?
Only if the goods originated in the European Union and meet the direct-transport rule under CETA Article 14. Transshipment through a third country (India, China, Singapore) is allowed if the goods remained under customs control and did not undergo further processing. You'll need a EUR.1 or origin declaration from the EU supplier plus transshipment documentation.
How long do I have to correct an HS classification error on a CAD?
CBSA allows voluntary corrections within four years under section 32.2 of the Customs Act, but penalties under AMPS increase the longer you wait. If you catch the error within 90 days and the duty difference is small, we typically file a B2 adjustment. Beyond that, expect a formal Section 32.2 request and potential interest on unpaid duties.
What happens if CBSA opens a verification on my India or China shipments?
CBSA may request commercial invoices, packing lists, bills of lading, manufacturer affidavits, and payment records to verify value, origin, or HS classification. The importer has 30 days to respond (extendable on request). Failure to substantiate the declared information can result in re-assessment at higher duty rates plus AMPS penalties starting at CAD 1,500 for Level C infractions.
Do I need a different RPP bond if I start importing from a new country?
No. Your release prior to payment (RPP) bond covers all imports regardless of origin country. However, if your volumes or duty exposure increase significantly due to new sourcing, CBSA may request a bond increase. Most brokers recommend keeping your bond at least 150 percent of your average monthly duty and GST liability.
How do I find the right HS 6-digit code for a product made in India versus China?
The HS code is the same at the 6-digit level worldwide, but Canada's 8- or 10-digit classification can differ. Use the HS classification tool or consult the Canadian Customs Tariff published by CBSA. If the good's material composition or use differs between suppliers, the classification may also differ.
